Power Supply Making Loud Noise

Question: Power Supply Making Loud Noise

I have a home built computer, (not built by myself) and the power supply makes loud noise almost like the fan is hitting against something. I have checked the fan, and it is clear of all contact, and this is not constant. There are times where it will be too loud to even sleep with from across the house, and times where it runs quiet as a mouse.

When it was making the loud noise, I was moving the computer to get a good look at it, and when it hit into the corner of my desk, the impact stopped the noise. I know it is coming from the power supply fan, but there is nothing for it to be hitting so I don't know whats causing it.

OK, so for a few months now, my one year old computer's power supply box has been making a very loud noise after I start up my computer. It lasts anywhere from 3 to 10 minutes. And lately the sound comes up even when my computer has been on for any amount of time after I turned it on.I recorded the sound:http://www.youtube.com/watch?v=i9-s7mUXfH8It's pretty loud if you're there in the same room, or even outside the room.Now, I opened up my computer because I naturally thought that it was dusty, which it was. So with my computer off, switched to 0 and unplugged, I dusted it inside and out. I made sure to hold each fan still (one on the mother board, one on my graphics card and the one in the power supply) while I cleaned the dust using a pressurized can of air. (FALCON Dust-Off Professional)I did open up my power supply and dusted everything in there to, very carefully. I then made sure that nothing was hitting the fan in the power supply while it spun, there were no obstructions, everything seemed that it'd be running smoothly. I then put everything back together and made sure everything was in place. Turned on my computer and it still made that noise. So I'm still not sure why it makes that noise. I checked to see if my computer was overheating, but it wasn't hot at all, and it's definitely in a ventilated place, all sides of it (vents) have nothing in their path. So I'm still not sure why that sound it happening or what is making it. ... Read more

I have an "ANTEC EARTH WATTS 500watt 80 Plus" psu that is starting to make loud noises. It's happening when I turn the pc off for a while... Say 5 minutes or more. It'll start humming loudly until I shut it off, and press the power button 5-10 seconds after shutting it off. It always comes back on without the humming sounds and works perfectly the second time around.

Today it was acting even weirder. I had the pc off for a while so as usual it made the sounds when I powered it on, but than next thing you know it went away on it's own after about 2 minutes.

Does anyone know what could be causing this? I tried vacuuming the back fan vent. It doesn't look SO dirty back there. Just normal dust build up... This thing is about a year old. I also looked back there to see if the fan wasn't spinning at anytime, and that's not the case because it seems to spin fine with and without the loud sounds.
Thanks

The fan on my power supply is making a strong whining noise. Do I have to replace the unit or is ther something else I can do to remove noise. At the moment I'm giving it a dunt and it stops for a short time. If I do need a new power supply are they all standard and are they easy to replace.Many thanks.

Answer:Fan on power supply is making whining noise?

I personally wouldn't go into a power supply, I would just replace it. Are they standard? Yes to a certain degree but what make and model of computer do you have as some manufacturers use non standard power supplies?

I built my own pc about a year ago. Lately whenever I boot the machine up it makes this weird buzzing, clicking noise. It generally stops after it gets fully booted up. Then it is quiet, but sometimes it will start making a buzzing noise after it has been on for awhile (I leave it on all the time). At first I was worried it might be the hard drive, but I have not had any real trouble with the machine. I figured if it were the hard drive, it probably would have died by now or I'd have some serious issues. So, what do you think? It would have to be the power supply or one of the internal fans right? Should I replace my 400 watt power supply?

Thanks!

Answer:PC making loud noise, could it be the PS or something else??

Its probably a fan. I would take it out and take a look at it and put it back. You first have to find out wich fan it is.

I have had similar problems. I used to hit the fan a few times wih a screwdriver and it fixed the problem. I am not recommending it though. It was my PSU fan. Maybe u should clean it. Be careful.

What happened to me one is that the CPU fan's mounting came loose and was not stable. Check to see if everything looks secure on it.

Hi, when I bought my PC two years ago, it was silent, it barely made any noise. However, I later made a huge mistake. I opened the case to clean the inside of the computer with an air compressor, but while I was cleaning the fans I wasn't holding them so the air compressor made them spin faster than normal. Following that, every time I boot my PC now, it makes a loud noise and also the PC makes a lot of noise in general. A lot more than when I bought it, to a point where sleeping next to it when it is turned on is a hard thing to do. Now, I'm wondering if that mistake is the cause of the noise. When I look at the fans, they don't seem to be damaged at all. I have 3 fans: The case fan, the graphics card fan and the power supply fan. My PC is cleaned regularly so I know it's not dust or anything that's causing the problem.

Here's some interesting info: It only makes noise when it's booting after the computer has been turned off for more than 30 minutes. If it's less than that, it doesn't make the loud noise. I have no idea why. Also, about 3% of the time, the desktop doesn't get to fully load because the computer freezes. It's a problem that started at the same time the noise started. If it is indeed one or multiple fans that are broken, how can I know which one(s) is?

I made a video of when I'm booting the computer so you can hear and see what is happening.

Answer:My PC is making a loud noise

You didn't tell us the brand and model of the computer.
Using an air compressor is very bad, because you risk the damage of static electricity that is generated in amazing amounts. Next time, us canned air designed for use in cleaning computers.
Replace the CPU fan, us buy a new CPU cleaning kit, and any fans that blow air to the outside, and replace the power supply with one of decent quality. Clean the dust of fan blades and computer walls with a soft rag soaked in denatured alcohol. Get some nylon or plastic ties to hold the cables together and away from any fans. Tie down SATA and EIDE cables so they cannot block air or rattle. Make sure all air flow passages are free and allow full movement of cooling air. All these will likely return your computer to normal. You could also buy "silent" cooling fans for very little money which would reduce your noise even more..

Answer:My Satellite C855 is making very loud noise

On this virtual way we cannot say for sure what the problem is but I can imagine that cooling fan is responsible for this.
From the first moment when you switch your notebook ON cooling fan is active so I would like to know if you can hear this noise from the first second after start-up.

Is there some other kind of vibration?

Of course it is also interesting to know if your notebook has valid warranty or not. If yes I strongly recommend you to contact nearest Toshiba service provider, explain the situation and ask for help.
They can order and exchange cooling vent.

I never had this problem before until recently I noticed that my fan was making this loud buzzing noise. It was bearable at first. I thought that the fan might be dusty inside because I haven't cleaned it ever since I bought it. Last week, I tried to open the laptop so I can check why it is making that loud noise. I saw that the fan was dirty. I tried cleaning it. When I turned on my laptop, it was still making that loud buzzing noise. So I just ignored it. After a week, It suddenly got louder. It didn't sound normal anymore. I tried restarting the laptop but it still makes that noise. Its annoying. I took a video so you can hear what my fan is making.  It just keeps doing like this even if my laptop is just on stanby, like I'm not doing anything with it. This is what it sounds like when I did the Dust Removal tool on Energy Management.   Since I kept using the Dust Removal tool.. Now its making this weird noise, like the fan is getting stuck on something. I don't know what to do anymore. Its been 2 years since I bought this laptop so I don't have anymore warranty and I never had problems with my laptop except for today. I have never dropped it so I don't know why this is happening to my laptop. Please help me.

Answer:Lenovo Y510P fan making really loud noise.

Hi there, Xbelleh -
Thank you for writing in to the Lenovo Forum - happy to have you here today.
 
This video would leave me to believe that a piece of paper or other debris shifted inside and is now coming in contact with the fan blades.
 
When you use the dedusting cycle the debris is temporarily being blown out of the way of the blades.  What I would do is use a can of compressed air and blow out the fan assembly from both directions and see what is blown out.  Compress air is available at any office supply store, electronics store or big box discount store.  When using the compressed air use short bursts as an extended burst may damage the fan's bearings from over revving. 
 
Also, when using the laptop take note of its position.  If the fan is quiet on a flat surface, but is noisy when sitting at an angle like on your lap.  That might be a good indication that the fan bearings are failing. 
 
Worst case scenario is you need a fan replacement.  The fan is something that the owner can replace if you are comfortable working inside it.
 
As a do-it-yourself project it can be fixed in an afternoon. At this point I would try the compress air and we'll go from there.  
 
Update us how it goes.

But if I ever moved it, the vibrating noise would come back. But today, the noise got really loud and it wouldn't stop this time unless I shut it down or something. Why is this? Is there any solutions to get this fixed, too?

So my laptops fan started making this really loud rattling noise. It makes me very self-conscience about me when I'm in public, so I just don't bother bringing it along. But I really need my laptop with me. The sound usually comes out at random. I've searched the HP Part Picker Store and under the fan section it just lists the fan pad, which isn't what I need. I do believe that I need to completely replace the fan at this point (I've tried fixing the problem from cleaning the fan out from dust to checking it for any damage, but can't find what the problem is). Would anyone know where I can find a replacement fan for my laptop and would I need to buy it with the whole heat sink and thermal compound? I'm pretty experience in computer repair so I have some confidence that I can do it, plus my warranty expired in 2014 so I won't be voiding that anyways. If it helps any, the product # is A3E83AV.

I bought the HP Pavilion x360 m3 Convertible 2 in 1 laptop online from Amazon September of last year. Everything was fine until around November where it was making this soft, but noticeable mechanical sound when I turned it on. I didn't pay much attention to it because it was not obnoxiously loud at the time, and I make sure that the fans are breathing and not collecting dust. However, now it appears that the fans are like jittering and making this whining noise when I'm on. I don't run a lot of programs at once on there nor do I leave it running for a long time. The noise is really bothering me because I can't even bring it to class with me because of how loud it sounds!  I tried everything, updating the BIOS, doing system checks and diagnosis through the HP support assistance, I always keep it clean and I use compressed gas to blow the dust that I could find in or around the laptop as thoroughly as possible. Still nothing. I have no clue what to do so I hope someone can help me, please. Thanks!

It seems like some sort of fan problem because usually I can feel the heated air coming out from the side but right now I don't feel it so I guess the heat cannot escape because the fan wouldn't blow the heat out!

My warranty is over too, it's slightly over a year that I bought it.

Hi Girom, It sounds like the one of the laptops fans have gone , Buying a likely replacement is not so difficult if you go the Ebay route search out your model in "laptop spares and accessories" ,Installing is not too hard to do either .
I don't think a laptop cooler will help you much as it's not direct on the CPU or GPU

Hello all,

I've been having this problem for a long time now (2 years) and no matter what I do I can't get rid of it.

My PC will freeze and make very loud buzzing noises a few times a day,even when left idle in the middle of the night it will sometimes wake me up with the buzzing sounds coming out of my headphones.

I'm clueless at this point as for what to do,I replaced my Motherboard,my network adatper, I disabled my sound card,played around with the BIOS settings and nothing works.

There is one way which seems to consistently recreate the freeze & buzzing sound and thats only when I run low graphic games and let me explain:

I can play heavy 3D games with demanding graphics and the PC wont freeze (Actually don't think it ever froze while I was playing a 3D game) however It will freeze after less than 10 minutes if I play a low demanding game like Stardew Valley,League of legends or even when the PC is just Idle or while listening to music on youtube.

I ran Memtest86 and Prime95 and didn't find any errors and the event viewer errors seem to just say its Error 41 which is an unexpected shutdown.

I would really be greatful if someone can help me solve this annoying problem for once and for all,I've been living with it for so long,it makes me paranoid when I'm gonna hear it while listening to music (the sound gets you jumped every time..)

Hey all,

First timer here with very little computer experience. I've been browsing the forum via google, and I noticed a bunch of people had the same problems as I do right now. However, I have no idea if I have the same problem as them, and I would be grateful if someone walked me through this. I have a DELL latitude D620 running XP SP3. I use McAfee Total protection 2012.

Basically, in the past month or so, my CPU has been gradually increasing to the point where every couple of seconds it becomes 100%. The computer is still usable, but it overheats signficantly and I want to catch the problem (if there is one) before it becomes worse. The biggest contributers to this problem are services.exe and about 8 different svchost.exe running at once (sometimes ALOT more than that). These typically take up at least 50% of the CPU at any given time.

Answer:XP making continuous loud whirling noise when starting system, no boot up

Sounds to me that maybe its a bios problem . When booting the default place that windows looks to get its startup info from is the HDD. If that was changed, say to cd drive then it would look there. No info there would mean its stuck in limbo. Try searching the site for bios or boot up problems. This situation is far from new and ,hopefully its not your machine, you will find the right solution for you.

Answer:Supply fan is making a lot of noise!

Lubricate the fan.If you are able to, then 1) Take the power supply out of the computer casing by unscrewing it. 2) Remove the cover of the power supply. 3) Carefully Unscrew the fan. 4) At the center of the fan will be a sticker. Remove that sticker. 5) After removing the sticker, there will be a small rubber cap fitted inside the center of the fan, take some sharp object or tweezers to remove that rubber cap. See this image: http://www.dansdata.com/images/fanmaint/peel500.jpg6) Buy a small bottle of one of these: http://ecx.images-amazon.com/images/I/21PYLXjAzRL._SL500_AA300_.jpg Its very handy. Called WD-40.7) After removing the cap, in the cavity, spray 1-2 small drops of this spray. Rotate the fan with your finger a few times. Hold the fan and move it up and down a few times slowly without breaking anything, so that the lubricant reaches inside properly.8 ) Re-fit everything. Be careful with the wires, they should not get stuck in the fan while re-fitting back.

Question: loud power supply

I have one of those cheap wal-mart hp pavilion 533w's. It's been good to me for three of four college years, but now the power supply is being louder than my neighbor on the weekend. I know I just need to replace the thing, but that's proving harder than I thought it would be.
I managed to put another harddrive in this user-NOT-friendly thing, but I can't for the life of me figure out how to get the housing off to get at the dern fan. Everything is either rivited in place or just too confusing. I'll post some pics of what she looks like on the inside, and from the back. If anyone knows how to perform this delicate little surgery, please share the love.

Yesterday me and a friend was building me a new computer and got everything hooked up(or so we thought at the time) and booted it up with no problems. Then we noticed we forgot to hook up the CD drive so we opened it back up and hooked it up.

Then this time when we turned the power supply switch on there was a loud pop that came from it and the only things that seem like they are working are the fans and the led lights inside the case.

Could it be the power supply at fault or could it have caused a problem somewhere else like maybe the graphics card or motherboard itself?

Answer:A loud pop from the power supply

I would get a new powersupply . you really cant diagnose anything else .

it is likely that something in the psu blew and it cant supply enough power to start the system

what brand and model psu is it?

Never had this noise before but now its making a lot of noise. Its annoying. Usually my PC is quiet, but this thing is loud all the sudden. When I get the noise, I shut off my PC and start it up and the noise is gone for about 5-10 minutes then it comes back again! I can pick up the front of the case with 4 fingers and drop it (no damage btw) and get a break in that noise. If I do that multiple times it goes to normal sound for a few min. WTF is going on? Can I fix? I don't want to buy a new one yet. Wanna fix it first.

so i bought a retailplus brand power supply and gforce 960 videocard less than a year ago and when playing games it gets loud...is this normal? I cant find reviews on this product but at the time i didnt know any better or how important is it not to cheap out on a power supply but my local staples store carries two brands and this is one of them. I dont want to even play my pc atm cause i'm worried it gonna fry or something. any specs are
amd a8-7600 radeon r7 10 compute cores rc+g6 3.10 ghz 8gb ram 64 bit os 64 based processor 600w retailplus powersupply geforce 960 4gb video card
 

Answer:power supply is loud when gaming

Never heard of retail plus and I would assume its a generic power supply of poor quality.
The quality of a PSU is paramount to ensure the system runs stable and also can handle any transients, they need to be efficient too.

Some brand that I tend to use are

Corsair
Antec
Thermaltake

What you need is something that is something that is

+80 bronze minimum efficiency certified
Has Active PFC
a SINGLE 12 volt rail with a minimum of 40 amps

if the PSU is making noise I would replace it immediately. Though it would be good to know what kind of noise it is making?

3 yr. old, gaming desktop (custom built); sounds as if a fan was hitting something; seemed to be coming from power supply; tech guy said, sounds like power supply; i sprayed condensed air, especially around fan; lifted up computer, moved it around a little: noise went away ! i had put a phone book on top of computer a few days ago (this probably has nothing to do with the noise); tech said he would charge $150 dollars, if it's only the power supply. is it 'ok' to keep using the computer, as long as the rattling, loud noise doesn't come back ? tech guy said maybe i need more power to play games; i was playing game 'risen'; some of the system requirements say you need 2 gb ram to play 'risen', others say 1 gb; my computer has only 1 gb ram; the game runs a little slow, choppy sometimes; thanks
 

Answer:Rattle (loud) : Power supply ?

Greetings, xjimmie6...

Sounds like a fan bearing going south, or the blades hitting a cable...

You can actually replace the fan in a power supply (it's no different than other system fans - you just have to make sure that the replacement has the same connections and footprint)...

As far as the memory needed for your game, I would think that more RAM would certainly help: even if the game only requires 1gb, a good chunk of your memory is being used for your operating system, other programs, etc...

Hi, so I have had a powering issue with my previous power supply which was the Corsair CX600W so i purchased a newer power supply - the EVGA SuperNova G2 550W. I unhooked my old psu, hooked up my new one and the PC turned on and I turned it back off from the power button on the case. I also hava a boot drive problem so I unplugged the sata cables from my SSD and wanted to try to turn on the PC with only my HDD. I did this with the PSU switched off and the power cord unplugged. When I tried turning the PC on again the PSU made a clicking noise and nothing turns on. The motherboard Led's are lit up so it is definitely getting power but when I go to turn the computer on it just makes a quick clicking noise and nothing turns on. Any help is appreciated, thanks!

Hi,

This morning I removed my main HDD to plug it into another PC and transfer some files. I have now installed it back in the original PC, but it will no longer boot. There is only a loud, high-pitched sound coming from the PC. I have cleaned the inside thoroughly with compressed air. If I remove the graphics card, the sound is no longer emitted. I have had a lot of trouble recently with my computer, most notably with my monitor remaining completely white upon startup. Turning the monitor on/off about ten times tends to fix the problem and the monitor will then display normally until the next shutdown/startup. I tried the monitor on the second computer and the same thing happened with a white screen that would fix itself after being turned on/off repeatedly. My main concern at the moment is the loud whining from my first computer on startup. I am not sure where to begin troubleshooting any further: does this sound like I need to replace my graphics card, PSU, or something else?

PSU: HEC-550TD-PTE
Graphics: GeForce 8800GT

Any help would be greatly appreciated.
 

Answer:No boot on power up w/ loud continuous high-pitched noise.

First, the hard drive. Sounds as if you have messed up the Master Boot Record by connecting it to another PC. This can be fixed by I need to know the OS.

Secondly it also sounds as if your graphics card has failed or the fan on it is making the noise which will need to be replaced.

Finally as your monitor is producing the same fault on another PC then it needs to be replaced.

Hi

About a year ago, a technician changed a Bios setting so that the computer would not be too loud. Last week, I was trying to identify a shut down error and reset the bios to default. The error was found, not to be a bios setting but a failing Power supply, which has been replaced by another technician. It is the same power supply I had - Antec 430. The computer is now very loud again.

I have an Asus A7N8XE-Deluxe board. I enabled Q-Fan Control . I left it at the default setting of 15/16 and the speed up/down response time as 4sec/8sec but this has not made a difference.

Please do you have any suggestions?

Thanks!!

My new X1 is great for crunching through data but the power consumption seems very high at idle or when I am doing simple tasks. I have BIOS version 1.27 (released 21/Oct/2011) and Power Manager 3.62 I have used Power Manager to set Power Use to "High energy savings". However, the power used is always >20W and usually around 25-27W. This results in excessive heat (so the fan goes at 4500rpm all the time) and the battery is lasting less than 1 hour if I give a Powerpoint presentation (no movies). Also, the Power Manager shows GPU at 100% all of the time - is this normal or might it be a cause of increased power requirements? I have tried all the solutions to fan noise in this thread:http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/x1-fan-Noise/td-p/469001 I have tried setting all power settings to maximise battery life in Windows 7 and then also in Power Manager but to no avail. Please help! What are the ormal power requirements and GPU% at idle?













Solved!

Go to Solution.

Answer:X1 - high power consumption (>20W), GPU 100% all the time, short battery life, loud fan-noise

Check Task Manager to see if there's anything running that is using CPU.As far as I know, there aren't any tools for determining which program is using the integrated GPU. You may try ending services one at a time.

Question: Power Supply noise

I am having trouble with computer hanging up and it happens after start up...things can be running for a while but then a noise...sort of a soft grinding, but not really abrasive grinding if you get my drift, comes from the power supply. The fan is running smothly and doesn't change during the noise. i have isolated the noise to the supply. Hav e stoped the CPU cooling fan for example. Am I in need of a new power supply. Seems a weird thing to fail. No? could there be any relation to hard drive problems or is the noise a pretty determining factor that something is a miss with the power supply?

Question: Power Supply Noise

I bought a T61 back in June of 2008 (so about 10 months old), and I've recently noticed noise coming from the power supply.  Usually it is just a faint hum that often accompanies electronics, but often it 'chirps', or sounds like static. 1) From what I read online this isn't normal/ good. Is it common?2) What is the chance of the power supply totally going out?3) Is this a warranty issue? Thanks

Answer:Power Supply Noise

since you are within warranty, you can just call Lenovo up and ask for a replacement.  It could be on the way out, large chirping noise usually means something is loose in the adapter.

Question: Power supply noise

Is it possible for a power supply to make a mechanical type noise and I don't mean the fan itself. I have a 5 year old Dell 8250 and I think I finally isolated a case noise to the power supply area. The noise is intermittent and almost always present on boot-up. I stuck my ear next to the fan and it is starting to sound like the bearings are getting tired. Ordered a new one as they're so reasonable.

I only ask about the power supply because I really don't feel like buying one if I don't have to. Despite it's 250 watt rating I know Dell is very conservative in rating their supplies. It also seems that every time you change anything major on a Dell it's a nightmare due to their proprietary nonsense. With no moving parts(except fan) I would hope the supply is not my noise. Thanks for any opinions.
 

Answer:Power supply noise

there are lots of things that can start to oscillate in a PSU as it gets older
although I would not say it was mechanical, so it may be the fan

I'm looking at the two new antec truepower 2.0 550w power supplies. One is the normal 550w 2.0 with one 120 mm fan and a huge grill on the edge. The other is the 550wEPS12v with one 92mm fan and 1 80 mm i believe. Obviously one is going to make more noise than the other but also theoretically; cool better. I'm wondering which one to get. I have a 24 pin motherboard and a pci-e x800 pro but both of them support that. They are exactly the same power supplies besides the fans. They are only 2 dollars apart on zipzoomfly.com (EPS12V being $2 more)...please help me make this decision.

Answer:Silence vs. noise in a power supply?

An EPS version is normally meant for servers, where reliability is the main concern, and it will probably have been tested just that little bit more.
Their noise-levels appear identical.
The 2-fan version has that extra bit of safety built in, if one fan breaks down.
Either version will do great on your PC, as you will have plenty of reserve.
The 550w is slightly exaggerated, and is only PEAK-power, not sustained power.
As a rule of thumb, calculate your PCs powerneeds, then add at least 30% on top of that, so your PSU need not run at maximum performance.
Calculate here:
http://www.jscustompcs.com/power_supply/Power_Supply_Calculator.php?cmd=intel

Given the choice, I would go for the EPS-version.

Hello a guy just builded a computer for me. just someone in the Family knew him and i cant contact him again about this problem. so the problem is that when i run powerful programs that makes the computer very warm. a strange noise started coming from the computer for like 1 and a half month ago. and now the noise suddenly started getting louder. i think the problem comes from the Power supply. the noise only comes from the Power supply when i run Powerful programs like computer games that is very huge. for example the game grand Theft auto 5. the moment when i open that program the Power supply starts making a loud noise and sometimes the sound stops for 2 Seconds and then comes back.

i am getting a bit worried about this strange sound and specially if it comes from the Power supply. i also Wonder is it actually possible that the Power supply can start burning since there might be something wrong With it?

i have no idea how to open up a computer so i just hope someone here have any ideas what the problem could be?

Yes, a pw supply can smoke and or arc with sparks. You need to be sure the noise is in fact coming from the pw supply. In order to find out, you are going to have to open the case. If you are not comfortable working inside the case, then the next option would be to take it to a local shop and have them see what is causing the noise.

Just bought a replacement AC adapter for my Dell N7110 laptop off the secondary market, and it works fine except that it's emitting a constant high-pitched whining noise. The noise isn't loud, but I have never had an adapter make ANY noise before. Is this safe to use, or should I be sending it back?

It's a genuine Dell product, not an off-brand model, and was kind of hard to find. If I have to replace it, what's a good alternative to the Dell adapters?
 

Answer:Whining noise from power supply

i would send it back , although it may be OK and nothing to worry about

Ok, this started maybe 2-3 months ago with an "electronic scratching" noise coming from the vicinity of the power supply. I don't believe it is fan related, and hopefully it isn't a capacitor. It will respond to certain actions that I perform like moving the cursor around or increased cpu usage. It will however cease when my video card is under a heavy load, but it does not come from the gpu. The only info I have found about this has been with Mac users, which however I am not. Anyone out there have any ideas as to what is causing this, or how to resolve it?

Answer:non-fan related noise coming from power supply

well its definately NOT going to be a capacitor. i would suggest cleaning ALL the fans in the comp unless you zeroed it down to the one fan making the noise. (you know, take the shot-gun approach, if you dont know which one is doing it, do all of them! )

So here's my problem. I've built/had my computer for about a year and I have had no problems yet until recently. So I turn my PC off for the night and in the morning when I turn it on nothing happens my computer wont turn on, but I hear this noise coming from the PSU. I check all the wires and everything is in place, so I try another plug in cord same thing. Then I switch the PSU with another one I had and the same thing happened, a faint buzzing noise coming from the PSU. Lastly I took the PSU and hooked it to one of my old computers and there was no buzzing. So it must be the motherboard any suggestions on what the problem could be thanks.  I don't have the specs in front of me but here is what I remember. 450W power supplyXFX MotherboardGeforce 9800gt4Gigs ddr2Pentium D Processor80gb hard drive

Answer:Buzzing noise coming from power supply.

Something is causing the psu to overload, therefore it will not turn on.  Could be hard drive, optical drives, graphics card, keyboard, mouse, RAM, or motherboard.  Disconnect optical drives and see what happens.  If same, disconnect hard drive and see what happens. Then graphics card.  It might even be a locked cpu or gpu fan.

Hi I recently bought a 500W power supply and its been working great for about 5 months now.But recently, I've been hearing this crackling noise and it took me 2 days to find out where it came from, and I found out that it is coming from my power supply.My power supply comes with this little knob which controls the speed of the PSU, and I decided to give it a try and slow it down, and as expected the sound died down with it. But, the crackling noise stays. Not too loud, but still annoying.Out of fear that my computer would overheat, I turn up the speed every once in a while. Proportionally the sound would get a bit louder.It goes something like this: CRACKLE -CRACKLE -QUIET -CRACKLE CRACKLE - QUIET. And theres an occasional quiet squeal along the middle.

I have recently purchased an Equium A100 series laptop and am generally very happy with it however I have noticed that there is sometimes a background noise coming through the speakers (crackling and whistling) - this only happens when the ac adaptor is plugged in not when running off the battery. The noise is present in the onboard speakers and headphones/external speakers if connected. It is definitely coming through the speakers/headphones not from the mechanical parts of the laptop or the battery itself.

I see that others have had a similar problem too but no solution seems to be posted. I wondered if anyone has resolved this issue yet?

Many thanks.

If your PSU is noisy then the only thing to do is replace it, if you fit a quieter fan to it you could find it might not give enough cooling in which case if yoy are lucky it will just cut out if not 1 P/C up in smoke. If you need a new psu have a look here click here

Just 3-4 days ago, my computer has now been occasionally making sort of a buzzing sound. The sound is made like around once every hour or two (so I haven't been able to check exactly where the sound is coming from).

The sound is made even if my computer is idle and I'm not doing anything (though I do notice that after I turn on my computer, that sound isn't made until about an hour or so in after using my computer).

The sound isn't always exactly the same actually. Sometimes it sounds kind of like a scratching sound and sometimes a buzzing sound (sometimes in between). The buzzing sound lasts 0.5-1 seconds at a time, and sometimes sound sharp and the sound is very noticeable when it's made (not too loud but it is loud enough to be really noticeably when it happens).

The reason why I think it's the power supply is because I hear it coming from the bottom/back of my PC, where the PSU (and just above that, the video card) is located (the HDD is in front).

I tried checking HDD status using speedfan and it seems everything is okay regarding my HDD (so don't think it's my HDD but I'll try checking it again soon by placing my computer in a spot where I can more easily pinpoint the location of the sound).

Now, the question is what is the worse case scenario for what may be causing the buzzing sound? Like does it mean the PSU is going to die soon (if it's the PSU that is making the sound) or something else? Besides the sound, not... Read more

Answer:Power Supply making buzzing sound sometimes?

Was unable to turn switch on my very old computer so took in for repair. They replaced faulty power supply unit. Since I got it back home, it has continuously sounded like scanning is going on. It never stops even for one minute. It loads at the same speed as before when starting it up, but it takes 10 minutes now to get home page of IE to show up. The HD is quite full but was before I brought it in. I've now deleted a bunch of programs using Add/Remove but hasn't done much, and at even one point, it showed less free disk space after I deleted a whole bunch of programs. I've done Disk Cleanup to compress and delete temp, also ran %temp% and deleted all those temp files, only have some remaining few files in the Recycle Bin, scanned PC with Norton and Malwarebytes and nothing at all found. I did a defrag even though it said there was only 1% free space, it was unable to defrag many files.Have downloaded all Window updates except for one Office one. Phoned the repair shop and they never heard of this problem after installing new power supply , they want me to bring it back in but not very convenient to do so, and to wait days and days for it again. . Would anyone happen to know what this could be?
It's a 466Mhz Intel Celeron with 1GB Ram, 72GB HD with only 1.16GB free, WinXP Home

Answer:Continuous scanning noise after replacing power supply

<<72GB HD with only 1.16GB free>>

Generally...Windows will not function properly if free space on the Windows partition is less than 10-15% of total partition size. I have taken free space down to 11% or so (as an experiment) with no problems...but the general opinion is that 15% and above is desireable.

Hi, my power supply is ant Antec Quatro TPQ-850 850W or something like that. Anyways, It constantly produces this very soft and very fast kind of crackling noise, like the noise of Pop Rocks candy in your mouth. Thats the best I can explain it. Everything seems to work fine, but this noise kind of concerns me. And the weird thing is, I sent my first Antec TPQ-850 PSU back because of this noise, and the new one they sent to me still makes the same noise. Should I be worried? Or could this be a normal noise? Should I try again for one without the noise?

Thanks for any help.

Hi,

I have the following problem with my new Satellite Pro M70.
When the power supply is connected to the notebook a strange low volume whistling sound happens.
This sound happens even with the notebook OFF when the power supply is connected.

This sound cannot be heard in a noisy room but is quite annoying when you work in a totally quiet room.

Does anybody else have the same problem?

Answer:Satellite Pro M70: Noise with notebook OFF if power supply connected

Hi,

Sounds to me like you either have a bad ac adaptor, or the ac plug-in on your computer is touching something inside and making these noises. Best bet is to take it to your nearest ASP and have them check out the notebook for any abnormalities. You can try and test the adaptor if you have a voltmeter and see if the voltage is correct.

And if you can find another adaptor try plugging it into your notebook to see if the whistling stops or if it continues even with a different adaptor. If it does you can rule out the adaptor and you know its more or less something on the notebook, most likely the motherboard.

Hope this helps, have a nice day.

Enermax 450W power supply EG465P-VE(FMA)There is a continuous significant humming / burring noise coming from this power supply unit. This is not due to the fans as it is a different type of sound and it stays the same volume when the outside fan is reduced to its lowest rpm. This is an annoying additional sound. Is this suppose to happen?My old 230W psu was much quieter with only fan noise (no additional humming noise).My current system load is only about 250-300W.This would put a max 66% load on the 450W power supply. For this load the power supply specification quotes a noise level of aprox 29dB, but the sound appears significantly louder. Is this a faulty power supply?ThanksDave

Hello folks.

I have a high pitched noise coming from my power supply. It happened recently, and it's been lightning around here to boot. It's on a surge protector, but obviously we know that doesn't mean it can't still be hit.

Anyways, I can hear it fine but my dad can't. Before the tumor jokes start, my little sister can hear it as well, so evidently we both have tumors. I ended up unplugging everything from the power supply, including the motherboard, and turned the power supply on and off, and the noise only started when the power supply was turned on.

It still works, but it annoys the heck out of me. Obviously I want to replace it but I'm not sure if I can get an RMA. Is there any risk running it like this?

Hello everyone,


I purchased this power supply a couple of days ago to replace a no name 450watt "Deer" brand psu I had in my system for over 2 years:

Enermax FMA II DXX EG465P-VE 460W V2.2 2Fan 20/24P 2x6P RoHS ATX PS



Product Info: http://www.canadacomputers.com/index.php?d...&cid=PS.808


I've been hearing a faint humming sound from inside my pc case since the moment I turned my pc on with the new psu installed. I know for a fact that it's got to be from my new psu because it wasn't there before. It's such a low noise but so present that it's driving me insane. I feel like I'm the victim in that old poem by Edgar Alan Poe going mad over repeated annoying sounds I can't control. I'm going insane here! So much so that I'm actually going to take this psu back to the store this week if I can't find a logical explanation as to why this new psu would do this fresh out the box. Could it be the fact that the psu has two fans? Anyways I actually made a new choice for a different psu which I hope doesn't suffer from a similar humming sound:

Antec EA-500 500W ATX12V V2.0 PSU 80mm Fan 80PLUS ROHS Power Supply

Answer:Power Supply Buzzing & Humming Noise, It's driving me insane!!!

I think your second choice is a better PSU anyway. The humming may be from the fans, it may be from some type of vibration. A friend of mine bought a PSU that made a really annoying vibration sound; we pinpointed that it was vibration by pressing down on top of the case right on top of the power supply; you could feel it vibrating. If you pushed on the power supply like you were trying to jam the PSU into the case from back to front (in other words, pushing on the PSU towards the front of the case) the noise would dissipate. The problem was solved by getting longer PSU mounting screws and thick rubber grommets (or O-rings) and mounted 2 grommets on each screw, one outside the case and one inside the case. That killed the sound. Returning the PSU wasn't really an option in this scenario due to the fact that it was mailorder, and downtime was NOT an option esp. for a minimum of 5 days.
If the sound doesn't seem to be a vibration sound, then there is a chance that it's due to an internal component buzzing which is not a good sign, but it could also be due to the fans. You can check it to see if it is indeed the fans by simply stopping the fans from spinning for a few seconds. You can do this a number of ways; removing all but one screw holding the fan guards and moving it out of the way (with the PSU powered down and unplugged) will provide full access to the fan(s). Simply hold the fan in place for a few seconds when you power on the PC. It won't harm anythi... Read more

Hello everybody:

I have a Satellite A200-12x. My power supply makes a little noise. The noise is not very loud but it is audible only when it is plugged in, and some work is being actually done with the laptop.

As I say, is not a loud noise, it's a quiet "frying eggs" noise. Has anyone else noticed it? Should I get toshiba to change it for a new one?

Thanks in advance,

Regards

Manuel

Answer:Power supply of Satellite A200-12x makes some quiet noise

Hi there,

don?t worry, thats not a big deal. Since your AC must deliver many power to your machine (man, think about, you have a powerful A200 with really strong components -> CPU, VGA, RAM) and such a system needs a lot of power.

Due to this heavy power consumption, the capacitors and transistors in such AC-adapters are strong too.
You have to imagine that not only one capacitor is in there, no, there are over hundreds and some other components which have to regulate the power from the wall to your machine.

I have a Qosmio G30 and you wouldn?t believe what a noise its AC-adapter makes. It sounds like "Brrrrmmmmmmmmmmmm", like a little USV (a battery for desktop PC?s which prevents from data loss in a case of power failure..)

So, I would suggest you to accept it, since all AC?s of every new machine will make such noise.

I just got a new power supply aspire ATX 500W. Well now every time i scroll up or down a page with my usb Microsoft mouse the PS makes this noise that is so annoying. Everything works fine except for that dang noise. I have put the original PS in and it does not do the noise. Is there any way around this problem other then getting a new power supply. And if i do get a new one should i just return this PS for another Aspire or should i get a different brand. Thanks

Hi rezaulhasan , 
 
Welcome to the Community Forums. 
 
You can follow the power checkout guide as shown here on the hardware manual ( page 30-31). 
Checking on the LED status on each attempt would provide information on possible points of failure. 
Likewise while the machine is off, use the recovery button (item15 page79) to power on as this can also help isolate if the power button itself is having the issue or if the adapter / motherboard that needs further rechecking . 
 
Update us how it goes.

I did a search on this site to see what other people did when there PSU was having similar problems to mine. I ruled out that indeed it was the PSU, but using a tube so I could listen to where the source of the noise was coming from. So what I did was buy another PSU, I have a HP pavillion 753c ( i know ick, but it was a gift when I was in high shcool) I had a Bestec ATX-1956D B2 (0950-4106, 200W) - (atx1956d), and I figured I had to get one that was compatible, so I replaced it with a 200W micro ATX PS3 Power Supply. New PSU info link.
After the new PSU was install I turned the computer on and experienced the same problem, the noise was yet again coming from my PSU. Here is the catch though if I tap my hand on the back of the PSU fan from outside of the case it will stop making that noise, but the second I reboot it starts making that noise again. I dont believe two different PSU could be causing the same problem but yet when i listen it is coming directly from the PSU fan. Any ideas?
ANother question I wanted to ask is, is it possible for me to get any type of PSU which is supported by a P4.

Hey, everyone. I'm a first time poster but I feel that posting here will bring me far more useful answers than calling tech support.

My computer is a Compaq Windows Vista, Basic Home Edition. It's got 2.50 GHz of RAM and is fairly new in my opinion, purchased in the spring of 07. It has only one PS fan from the looks of it, the one facing the back to suck air out.

Shortly (guessing 3 months) after the purchase of my new computer, the Power Supply failed, and I had it sent off to the manufacturer for two weeks to be replaced. Since then it has been running very smoothly.

About a week prior to this occurrence, my computer made a similar noise (to the beginning of the video, link provided below) and more central in the computer. This was due to a dust build-up, which I cleaned out thoroughly. It was fine after that.

The matter at hand: This morning I turned on my computer to find it making ungodly grinding noises, coming from specifically the back of it. I turned it off and opened it up, cleaned out any remaining dust from the last time and turned it on with the side panel off to watch the fans. After listening and turning it off the second time, I decided it was coming from the power supply, since I'd realized that this was the only location I hadn't cleaned the last time.

I cleaned it with compressed air as carefully as I could, but there wasn't that much dust inside of it, nor on the fan. I turned it on a third time and the noises had quieted dow... Read more

hi mehilton,
 
Welcome to Lenovo Community Forums!
 
You can check your system's Hardware Maintenance Manual and check (page 45)
   this is a Part list and upgrade option. You'll find the Power Supply compatible for your system and its part number.

You can call Lenovo Spareparts (877 4536686 and prompts 4....3....2)    about the part number if you're planning to purchase one.
 
Technically a Generic ATX PSU will work on your system but the problem is some connectors on a K410 PSU is specially made for it and a feature like the Power mode Ambient light will require a original K410 PSU
see this discussion.

 
Hope this helps
Cheers!

Hi everybody, I would like some help!

I recently bought a new fan to help with cooling as the summer approaches. My new fan replaces my old chassis fan but is plugged in slightly differently as it is plugged into the 3 pin mother board connector (the old one was plugged into the molex and is now positioned as an intake fan at the front).

My problem is that since I've installed the new fan my computer is actually louder than before, Everest tells me that the revs for the new fan are 5114 rpm as I type this so it's clearly working too hard. I think it's working too hard because my processor fan is only idling by comparison at 1705 rpm. Which temperature does the chassis fan use to control it's speed and why has my CPU fan suddenly become lazy since I installed the new fan? Is there anything I can do to make the CPU fan work harder and take some of the burden off of the chassis fan?

Many thanks for any help!
