1st Build Power Supply Question

Question: 1st Build Power Supply Question

Hi, Guys (And Gals) I'm attempting my 1st PC build and HAVE used the various online power supply calculators... however I'd like to hear some feedback from you all. No matter where I look online I always like to come here to be sure. My specs for the build are as follows:

MoBo: GIGABYTE GA-F2A68HM-H FM2+ USB 3.0 MATX
Amd A6 5400K 3600Mhz Blk Edt 1mb 65w Socket FM2


Video Card: XFX RADEON R7 240 2GB DDR3 LOW PROFILE
RAM: ADATA XPG V1 DDR3 1600 4GB

HDD: Seagate 1TB Serial ATA HD 7200/64MB/SATA-6G

I would really like to use one of the 350W or 400W power supply I stripped from my previous PC's. I'm thinking of hooking it to an HDMI or VGA projector eventually though (Haven't bought it yet) Can I get away with one of these and play a game like World of Warcraft? or do I need to order something like the
SolidGear 650W PS2 ATX Power Supply on Tiger Direct?

Thanks in advance for any advice & thoughts

Answer: 1st Build Power Supply Question

Over engineer the PS;

Calculate the actual needed power,

add a fudge factor and

multiply by 1.5.
Then round up to the next commonly available size

I have a W540, which currently uses a 170W power supply (20V 8.5A) I also just recieved a docking station for a P50 which has a 230W power supply showing 20V 11.5A. The connectors look the same, but I'm hesitant to try the 230W power supply in the W540. Should this be ok to use the 230W power supply with the W540?













Solved!

Go to Solution.

Answer:Power Supply Question - Can I use the 230W power supply with a W540?

230 watts is the maximum power supply, it only supplies the power needed by the computer. I sold my W540, so i can't test this for you. But i do the use the ThinkPad X1 Carbon with the 230 watts power adapter without any problem.

Hello, everyone - I have just assembled a new build. It will not power up. I need a suggestion to figure out if the problem is the case or the motherboard.

This is a mini-itx build. The case is Linkworld LC820-01B. This case comes with a 12 volt 65 watt external, laptop-style power supply that plugs into the rear of the case just like a laptop power supply plugs into a laptop - a barrel connector. Inside, this power connection connects to a power supply component that is not like a regular ATX power supply, but is on a printed-circuit board mounted on the case. This has several capacitors and other stuff. From that comes the 20-pin and 4-pin power supply lines for the motherboard.

I assume the 12-volt power supply for this external power supply unit is right, since it came with the case. It was 65 watt.

The processor is an IBM 1155 3220t, with TDP of 35 watts. Lower-powered CPUs can be put in a small 1155, so I assumed the power supply might be under-powered. I ordered a 90-watt 12 volt power supply with the right size barrel - and same polarity (pos inside).

The MB is an ASRock H61MV-ITX. It is 1155, mini-itx form factor.

Still, same problem.

Everything is connected correctly.

When I press the power-on button, an external CD drive I have plugged-in spins up for a while. But no power light comes on in the front of the case, there are no POST beeps, the fan for the CPU does not spin up. No other signs of life.

So, power is getting into the MB - the external CD drive i... Read more

Answer:New Build no power-up: case's power supply or MB?

Well, I figured out the problem.
I am planning to re-do the older mini-itx system I have; it has gotten riddled with Trojan software for kids downloading games; it basically has been de-commissioned already.

So, I took the pico-psu power supply from that older computer, and hooked it up to the one I am making. Everything went perfectly.

So, I un-did that, removed the MB from case, disconnected the barrel-power connection from the case, unscrewed and removed the power supply that had been mounted in the case, put the pico-psu power supply back in place (I had to drill the hole for the barrel-connection out to be a little bigger since the pico-psu internal/external connection is threaded and held in place by nut with lock washer), and routed wires to be clear of cpu fan, screwed MB to stand-offs, and closed it all up.

now, everything is great. I like this linkworld case, but the power supply is worthless. I may try to get a few dollars back from the ebay vendor, to make me happy with a case that is less than what I should have gotten, but is working for me; I don't want to wait on returns, etc.

Answer:New build...bad power supply?

This is a new computer and tested fine at the store before bringing it home...right?Just a shot in the dark, but have you checked the wall outlet where you have it plugged in?  Is the power to that outlet controlled by a switch on the wall?  If so, you may want to see if the outlet has electricity going to it by plugging something else into it.  If you're using a surge protector...is the surge protector turned on?If worse comes to worse...you can always take it back to the store...that's your best bet since it is under warranty.Keep us posted...

Hi all,

This question is in regards of what wattage PSU I should use for this build. I don't do lan gaming but I do like games. I want to play Crysis.

Case: Lian Li V2000B, ThermalTake Armor, CM Stacker T-01
Processor: E6700 Conroe
Mobo: Don't know yet
Video Card: Nvidia 8800GTX or new release
HD's: 3 or 4 500gig Seagates Sata2
Sound Card: Creative Sound Blaster Audigy 2ZS Platinum Pro or newer
HSF: Thermalright X1-14 when released
Floppy
Card Reader
Two DVD- Burners

I will go to water cooling from Swiftech probably a year or so down the road.

My current system has a PC Power & Cooling Turbo- Cooled 510 ATX-PFC Deluxe and it has done me right. My PC was on one night and I was sleeping, a storm hit and I awoke to a burning smell that morning. My PSU was fried but it didn't take any of the components with it. That smell stayed in the house for three weeks.

I was personally thinking of a 850 watt PSU but if I'm off base here let me know. I looked around at PC Power & Cooling site and didn't see that size.

Open for advice, thanks.
 

Answer:Power Supply? For new build

You can get 1000watt psu's now, they arent hard to find, check thermaltake, silverstone, I know they have good ones. 850 would probably be minimal for that thing you're running.

My only concerne with the 500w it that i will not have enough power. And i dont know what the "Effencey" of the Ultra Power Supplys are? And i have seen on newegg.com that the "Effency" can be as low a 60%. So 40% of the power will be gone, meaning you dont rilly have 500w or 600w.

So if any one can help me with this, thanks in advance.

When I turn the power switch on, the fans all start spinning, but they all spin with this pulsating rhythm, and the case led display flashes with that rhythm as well.

On the mobo there are three power connectors that were supposed to go to my mobo; a 24 pin (got it), and 8 pin(got that too) and a 4 pin. I have 6 pin cables, a 4 pin jack on the mobo; i plugged in the 6 pin jack.

Hi all.

Originally, i was going to build a new PC with a single GTX 260 video card. I have since opted to build something a little different though. I was just wondering what size power supply you guys would recommend to me for my new build.

The full specs are:

CPU: AMD Phenom II x4 955 Black Edition
Mobo: Gigabyte GA-MA790X-UD4P
RAM: Corsair XMS2 2x2GB DDR2-800
HDD: Western Digital Caviar Black 1TB x2 (for Raid 0)
Video Cards: Asus ATI Radeon HD4850's in Crossfire
Optical Drive: Asus DRW-24B1LT

Cooling the CPU will be the Zalman 9700NT and will all be housed in the Antec Nine Hundred Two gaming case.

I was originally planning for a 650watt Corsair Power Supply Unit for this system. But i am beginning to wonder if that will actually be enough for the system. What do you guys think. Is it enough? If not, can you recommend me a good Power Supply?

Please dont say stuff like "you should get an Intel CPU and a single better video card" because i have already made my mind up on this system.

Thanks in Advance.
 

Answer:Need help choosing a Power Supply for new build

The Corsair line of power supplies is excellent. If you are not comfortable with the 650 try the 750; what do you need from the 12v in amps/wattage for Crossfire? Will you be overclocking?

By the way, love the cpu and 4850's in Crossfire and those WD Blacks have a good reputation. Is your system minus the psu ready to be assembled?

I currently have this (and don't want them to collect any dust:
Asus Motherboard
Quad Processor
DDR Memory

Plus a couple hard drives, but absolutely nothing else. Since this is new to me, I'm asking:

1 - Is there a way the more experienced users would suggest going about a new case and how to know the appropriate power supply to buy.

2 - I bought the MB used from newegg.com, and it didn't come with any wires/connectors. Can you tell me what I'd need to fully be ready when I have all the components?

Thanks!
 

Answer:New build case & power supply recommendations

I havnt done this in a while but here it goes.....

If you dont have the propor heatsink/fan combo you will need one of those for your processor.

For your needs just get a quality 500w PSU by Antec, Silverstone, Thermaltake ect ect. No $20 bargain buys. If you plan on putting in some super fancy graphics card, take the minumum requirments for that card off the box and add 100 watts.

Wires you will need are just your SATA cables.

The PSU should come with all you need to connect it to your motherboard.

I built myself a new PC:

Phenom II X2 550 3.2GHz
Gigabyte motherboard
2 x 2GB DDR3
Radeon HD770
Creative Audigy Soundcard
1 x 250GB SATA HDD
4 to 5 Case fans
1 x Optical Drive
1 x Floppy Drive

And I was using a 500W to power all that. After testing my PC out, it ran fine for a moment, then as I was adjust some power cables everything just shut off. PC would not turn on.

I tried another PSU of 450W with just the motherboard, and it worked. But as I started to connect more and more things. The exact same thing happened.

Do I need to buy a more powerful power supply? If so, what? I don't want to shell out $80 and have the same thing happen again. Should I go for something like 800W?

Please advise. Thanks.

Answer:Problem with Power Supply in my new-build - Urgent

Hi. I am a graphic designer switching to PC. i have done wok on my old mac (replaced ram, hard drive, dc in board) but this is the first time that I will be building a pc from scratch. Below are the parts I bought from new egg. there is one pretty obvious problem i think, the power supply is 400w. This was an error I originally had a 750w cooler amster and someone recomended switching brands and i was careless. i also forgot to get a wireless card. my question is, can I build this with the PSU I have and replace it later ( it was pretty in expensice and i am maxed out) or is it going to be a bad idea.

I have a server that I would like to upgrade to 20 1TB Hitachi HD's. They claim max startup current of 2A. and idling down in the .5A range. The platform will be a 775-series X48 with a 6600 Core Duo. Graphics card is small, does not even require aux power connector. Not needed to just supply the KVM with 1280x1024. No other signficiant sources of 12V drain exist other than the MB/CPU, a slim CD-Drive for installs, a slim floppy, and one additional 30GB SSD startup drive (2W when active).

I am looking at an 850W Corsair. I've heard these are quality supplies and I don't want multiple rails since no one really knows what sort of Voodoo goes on as to how they divide multiple rails up. And I don't want to get into that. I will be using a single-rail +12V PS. I can add a second if I need to but I'd rather not.

Do you think this will be sufficient for handling 20 Hitachi hard drives? "Green" drives are a non-starter since they will drive my Raid 6 controller, and then me, off the deep end with TLER issues. I do have staggered spin-up control of the drives with the controller.

Thanks for any help.
 

Answer:Power Supply Question & HD Power Consumption

Power Supply Question & HD Power Consumption, Pt. 2 - Laptop vs. 3.5"

My second question is this - I have a BTV server that needs to be on at all times during the season to record shows during day and evening.

Suffice it to say that you CANNOT reliably put one of the critters into sleep/hibernate mode and expect it to wake up and reliably record a show. It just won't happen.

Now, this is one case where I can use "Green" 3.5" drives, but I am also considering banking 500GB 7200RPM or even 5400RPM laptop drives. These will all be on a raid controller, but since they will be in pass-thru mode or RAID 0 mode the controller won't freak over TLER like it would with RAID 5/6 and mark the drives bad. The controller also has more than adequate cache to handle a 5400RPM spindle as OTA HDTV generates little more than 2.5MB per second per channel. Even 4 channels at once is 10MB/s and that should not tap the ability of a 3Ware controller with cache on 5400 RPM RAID 0 or even pass-thru drives.

My question is this - 2 500GB laptop drives burn much less startup and idle current than a single 1TB 3.5" drive. Has anyone tried running multiple laptop drives on a RAID controller, and what sort of luck have you had? What sort of sustained throuput can you obtain?

Electricity is a huge factor here, at 12 cents per KWh. I can recover the marginal cost of 2 500GB laptop drives vs. 1 1TB 3.5 drive.

Hey everyone,

Got a new compy a little under a month ago, and earlier this week the power supply crapped out on me. Big scorchmark around one of the big white wires inside it... not a great sign

Anyway my friend Paul who built the thing for me (certified tech and all that jazz) put in a 300W he had extra until we can get in a replacement part. Some of my friends are freaking out telling me not to even turn the thing on until I get at least a 400W power supply put in.

Is that unreasonable? Seems a bit excessive since I'm running two drives (DVD burner/DVD reader) and just the one HD. The specs are as follows, if you're interested.

Pentium 4 2.4 C overclocked to 3.006 GHz, 1024 DDR RAM operating at 200 MHz I think (don't really know or care Paul knows a lot more about that stuff than me ), 120 GB hard drive, Radeon 9800 Pro, the afforementioned DVD duo, and to view it all a glorious 19" LCD... because who needs money anyway?

Answer:Power Supply Question

I suggest trying this first:

http://www.jscustompcs.com/power_supply/

(Note that the processor power consumption may be a bit off, since it reflects the highest "C" stepping model, the 3.0-3.2, unless you decided to crank up its core voltage).

I've seen many who a supply less than what is determined on the site, without any issues, but it's always a good idea to leave some headroom.

But also, in this case, supply quality is a big issue; spend a little more on one that will be most likely less prone to early failure.

Hey all,
I have a PC (eMachines 2.8 P4) that would not power on at all - no fan noise, lights, no nothing. I narrowed down the problem to a faulty power supply - power supply tester showed no power output and swapped in a new power supply and now have power.

Problem now is, I have no video to the LCD monitor. Graphics is onboard. The new power supply I put in is a standard ATX power supply that does not have the ATX2 12v 4-pin connector for the P4. Without this being connected, will this cause problems overall and specifically with the no video problem?

Also, I seen a inexpensive adapter to go to ATX2 using the standard ATX power supply. Any opinion on doing this? Thanks so much in advance.
 

Answer:Power Supply Question

Yes obvioously you do need the psu with the 4 pin connector.

I've been running the stock HIPRO 300W PSU on my system for years now (recently been making strange noises from the fan) and I've been recently adding more stuff to my system. My case and MOBO's form factor is micro ATX. when i see a micro ATX PSU, it looks small and/or it doesnt even have the same bolt pattern. is this what i would buy if i might need one? any help is much appreciated.

On the T61p does the external power connection have two or thre connections?  I Have seen some diagrams showing the outer and inner shell to carry the 20 vdc with the inner pin power good.  Others show the outter and inner chell to be common with the innery pin carrying the 20 vdc.  I get unexplained shutdowns only on the power brick.  Could it be the brick is dropping a power good signal forceing the CPU to shut down or the system to power off?

Recently my power supply got damaged due to a thunderstorm even tough I had a
good surge protector installed.

Obviously the best protection would be to disconnect the computer from the plug.

But I wonder if just switching the surge protector off would provide the same security ?
Or could a lightning still cause damages ?

Although highly unlikely, it's still possible that a really bad direct strike would still find it's way down the path in to your PC.

As long is there is an unbroken chain of wire from the house electric system to your PC, there is a chance (albeit an extremely small one) that you could still suffer some damage.

IMO - is this likely to ever happen? No. Don't worry about it.

Hello,

Trying to diagnose a computer problem.

The computer does not boot up. It starts, and all fans are spinning, and the HD ( I tried 2 hard drives actually) seems to be spinning.

I am wondering if the PS is failing?

If the PS is done, will you get ANY power at all, or will you press the on button, and get no juice?

Also, there is no burning or "heat" smell coming from the PS.

If it is not the PS, my next guess is the MOBO, but I am not really sure how to test if a MOBO is pooched.

Thanks in advance.

I am looking at new power supplies and was wondering if it pays to buy one larger than you need at this time?

Does a 550 watt power supply draw 550 watts all the time or only when needed? If they do not draw to their maximum capacity, it seems like it would be better to buy one larger than you need right now because the only cost would be the drive itself and not an increased electric bill and more heat.

Does anyone here know if the talk I've been hearing about GF4 Ti's needing a minimum of 300 watt's with the power supply is fact or if it is some peoples idea of problems with compatability on certain systems? I went to the Dell and Gateway websites and they offer the 4600 in their systems that are powered by 250 watt supplys. I was hoping to find some facts on this. Also no reviews ever mentioned it.
 

Answer:GF4 Ti & Power Supply question

Everyone gets pretty confused about this. No, the card in itself does not require 300w, but will draw apx. 50w & up to 75w under load (extreme gaming) However, adding another 50w draw may tax your system, necessitating a 300w psu, or better.

That seems really high.I'm planning on some travel out of the US and need to get a step down transformer and am a bit stumped by this. I would assume one of the little "wall wart" ones would do the job, but want to be careful not to fry my charger. Is that 40 Watt spec safe bet? More to the point - do I even need to worry about step down transformers - does the power supply automatically sense/switch?  (I think that's really the case, but don't want to assume anything) 













Solved!

Go to Solution.

Answer:Power supply question

As long as the wall outlet voltage is within the specified range (in this case 100-240V), your AC adaptor should work as it is. Your concern is to get the right pin configuration for your wall outlet adaptor so that your AC adaptor can be plugged in.

I am still in the process of upgrading my sister's computer (question about switching from IDE to SATA hard drive earlier) and I have now hit a hurdle with the power supply.

She has a desktop case (which she will not change), so I was just using that and upgrading all the components. The only thing I am reusing, apart from the case, is the floppy drive. So, I ordered a new power supply, but it is too big. A local computer shop didn't have one the same size, saying they were specific to the case, so I take it these are special-sized components. Will I be able to get one at all? I am in the UK.

The one she has is 300W, but I wanted to get a more powerful one to run the newer components. I had to get converters for the power connectors, as the new hard drive and DVD writer are SATA and the existing PS did not have the necessary connectors. It looks like we may be forced to stick with that one, or else she needs to get a tower case. I have never worked with a desktop case before, so was unaware of this discrepancy in size.
 

Answer:Power supply question

There are several 'standards'.
You obviously need a psu to match the mounting screw and fan outlet positions, as well as the physical cube dimensions.

If it doesn't say something like NLX or SFX on the psu label post some pics and dimensions.

Answer:Hp power supply question

The easiest and quickest way to test the power supply is to take the tower to a shop where they have a power supply tester.

They can test the power supply and if the power supply is defective they also can "jump" a known good power supply to the motherboard to make sure that when the power supply failed it didn't take out the motherboard.

I do these tests quite often in my shop, takes about 30 minutes total time and the cost should be minimal perhaps $25-$30.

I put it to on and i push my power button on the front of my pc then it starts and stays on. Sometimes it doesnt work like that but rather after I toggle on and off the power switch on the power supply several times.

Answer:Power supply question

First of all STOP cycling the power on and off. You will make a bad situation much worse. Next replace the ps. Cold boot problems that go away after the first failed boot are almost always ps problems. Do not buy a cheap ps like powmax, deer, allied, foxconn, raidmax or any other cheap brand. Go with a quality unit like antec, enermax, coolmax, enlight, or sparkle. There are other good brands, however those are what I use in my builds.

I have a Thermal take 600w and It started behaving weirdly. The fan would speed up and down, I have several small LED fans on the case, and these would dim and slow down as well. The computer would run fine, no crashes, no re-boots and so on. If the PS fan was not working properly, would the PS overheat and cause a lowering of Wattage output? If so, then why the LED diminish, and no system problems?

Answer:Power supply question

Yes absolutely  a malfunctioning PSU fan will cause an overheating issue to the point that your computer will likely shut down. As to the diminishing brilliance of the LED lights that can also be the result of a malfunctioning PSU (inadequate power being provided). It can also be as a result of power fluctuations from the electricity source (provider/plug outlet/fault in the service within the location/other component malfunction). Not be ignored. truenorth

Hi everyone, I have a question.

I recently purchase a dell optiplex gx50 motherboard with a 1.1ghz, and 256mb ram. Its on its way right now, i havent recieved it yet. I'm using it for a project and I dont need to fit it in the original case. Anyway, the power supply for the mobo is available on ebay, but its considerably more expensive than a standard atx power supply, I think this is because its a small form factor so that it will fit into the gx50 case. NOw the gx50 power supplys seem to have a standard 20 pin connector on them to connect main power to the mobo. However, from what I can see from pictures the colors on the wires are different than most standard power supplys, my question is, do you think its just a dell thing and I can use any atx power supply or must I use the gx50 power supply. Also its a socket 370. I have seen on ebay some power supplys that say they support socket 370, I wonder if these will definetly work.

Thanks

Answer:power supply question

Yeah, that would be my best guess. If something says on it what it is compatible with it, then that. I'd say that your board gets power for like one miniscule bit of a second, then switches off, cause it knows that it ain't working with a p4. So if all other suggestions posted fail. Then that is probably what is wrong and you'll need a new psu.

I'm messing around looking at power supplies, and I saw this one http://www.newegg.com/Product/Product.aspx?Item=N82E16817159057&Tpk=CUG-600B and noticed it has three 12v rails. Cool. But.... the rails have a very strange amp setup: 12v1 is 13a; 12v2 is 21a; 12v3 is 13a. :confused Does that strike anyone else as strange?

Alright I'm a little frustrated right now but it might actually be a good thing. I was planning to buy an ULTRA X3 800w power supply from TigerDirect.com but when I looked today it was listed as unavailable, just my luck. The unit was listed at $199.xx and came to about $215 with shipping.

Anyways, I've been searching around and there are few retailers that sell this unit; it's been unavailable from ULTRA's online store. However, while I was browsing more listings I came across a sweet deal for the X3 1000w model, only $205. This model is listed on Tiger for $299 plus shipping. So, I just bought the unit because it was almost what I would have paid for the 800w on Tiger, came to $222 with shipping.

My question is, 1000w is probably way overkill for my system, would a PSU this powerful (70A on a single 12v rail) damage my system's components if I were to use it anyway? I think I need a minimum of 700w for this system - Intel q6600, two 8600GT's in SLi, three hard disk drives and two DVD drives. Not a very power-hungry setup so I am a bit worried about using this PSU. Any input on this would be greatly appreciated.
 

Answer:Power Supply Question

Wait for a second/third opinion, but I believe it would NOT, as the system would only draw the power needed from the PSU.

I recently changed from a 300W psu to a 480w psu. I have windoctor mobo monitoring software that came with my jetway mobo. This software shows the cpu speed, fan speed, temps, voltages etc.
Since the psu upgrade, the warning on the neg voltage (-12) is poping up an showing a value of right at -13 volts. Is this a problem to be concerned about?

But this one has to do with another cumputer here at work...

The power supply to one of the computers here at work is dead. Our tech guy came and took it with him but just called and lesft me a message asking how many pins the power supply has.

How/Where can I find this information?
 

Answer:Another Power Supply Question

If he has the power supply with him he should know how many pins it has. If he's asking about the main plug on the motherboard you can count the number of holes. It will either be 20 or 24.

My friend has an HP Pavillion with an AMD Athlon XP that just all of a sudden stopped powering up. I haven't personally looked at it yet, but it sounds like the power supply to me. Its about 3 years old and he leaves it on 24/7. Anyways, he wants me to change his power supply for him. My question is What kind of power supply do those computers use? I mean like is there a certain type of mount or am i just gonna hve to open it up and take a look at it myself? Can i just get any kind? I've never taken apart a store bought computer and his warranty is up so he asked me to do it for him. I'm trying to price out a power supply but don't know what to look for.

I have an old Dell 0M3918 Motherboard that has the original power supply. I'm looking to upgrade that power supply so that I can have more power, and most of the power supplies I've seen are 20 pin connectors. The board uses a 24 pin connector. Are these new PSUs compatible with my board? I can see they have a 4 pin connector that's 2x2, and my assumption is that you use that as well, but my PSU has one of those anyway and its currently plugged in at a different spot on the motherboard, well away from the main 24 pin connector.
 

Answer:Power supply question

All the 24-pin power supplies I've seen have a detachable four-pin part to make it compatible with the 20-pin boards. (The wiring is the same on the first 20 pins.) It usually is not visible in the product pictures; but, it is there. I have seen some detail pictures of supplies at NewEgg.com where you can see the demarkation point between the 20-pin part and the extra four pins. That's where it breaks.

As for the extra four-pin connection, that is separate entirely from the twenty-four pin part.

You can see fairly detailed pictures at NewEgg.

I have come to the realization that my IBM PC300PL 6565-85U's power supply can't handle two hard drives and a DVD-RW drive. It's a 140 watt. When I burn a CD, or start using the 2nd hard drive harshly if I have music playing it'll turn into a high-pitched squealing noise. Also, I get ticking noises out of two brand new Western Digital HDDs, in this machine while I didn't in my 480 watt Powermac. The ticking immediately goes away when I unplug a drive and boot with only one on.

I looked in my closet and I have a 200 Watt Astec ATX202-3525 power supply laying there that has the same layout as the one in the IBM now. I think it is still alive.

My question is basically what chance do I have of frying the board if this PSU isn't as good as I remember, and would those 60 extra watts help my case enough to justify putting it in. It came out of a Gateway GP5-166, and is a replacement for the original, so it's no more than 3 years old.

I really don't want to fry the board is the only thing, but I am getting sick of a dreadfully underpowered machine.

I just ran this: http://www.journeysystems.com/?powercalc
and I got a recommended minimum of 199 watts.

Any suggestions?
 

Answer:Power Supply Question

When it goes kaput, its failing circuits are capable of failing voltage regulations in all directions and can subsequently fry about anything in the system, including the board.

Frankly, I think cheap power supplies are responsible for more main board deaths than any other single cause; but, that is just my opinion.

My feeling is that you can't trust any power supply in the sub-fifty-dollar range and maybe it would be better to stick to $60 and up. It seems a lot of my main board problems started going away when I started buying Antec supplies in the $60+ range. Mine are all in the 400- to 480-watt range. I might not need quite that much wattage; but, buying lower wattages doesn't save enough to worry over. Also, the higher the wattage of a quality power supply, the less the strain and the longer the life.

Answer:power supply question

The SATA is used for connecting your drives. Your power supply for all I know doesn't need those type of connections. You just need SATA drives or SATA converters for your current drives, along with SATA cables. You could probably just by a power supply that has enough wattage for your motherboard and it should work.

Answer:Power Supply Question

As long as the voltages remain within the range of +5/-5% you have have problems. However, with a 500 watt PSU you see very little fluctuation. I would replace that one with a quality unit. Think of it this way. The PSU is the machines heart. Would you rather have a good heart or a Jarvic heart?

PSU1: 600w; 4 x +12v @ 18a each; +3.3v @ 36a; +5v @ 30a; 5vsb @ 3a; combined power for +12v 580w; 5 year factory warranty
PSU2: 650w; 2 x +12v @ 20a each; +3.3v @ 30a; +5v @ 54a; 5vsb @ 3a; 3 year factory warranty

Thanks.

(I'm not even sure that I need to upgrade my current PSU; it seems to be running fine, but it doesn't hurt to have a plan)

Why the off brand choices. I never heard of either one until today? If you want something reliable get a name brand Antec/ThemalTake/PC Power&Cooling heck even an Enermax over either of those two. Its your money. The first one has 4 - 12v rails and a 5 year warranty, and according to Newegg its pretty heavy, so it will have beefy caps and sinks.

Answer:Power supply question

I'm quite sure the answer is no.  No such data is passed from the PSU to some program in your computer or to Windows.  Some software tools, such as EVEREST Free Edition 2.20 can be used to obtain very detailed info about your hardware and software but I just looked at an Everest report on my system and it contains nothing about the PSU.

With the cost of electricity nowdays, I was wondering about power supply electrical consumption:
Does a typical power supply draw the exact amount of current it is rated at on a consistent basis or does it adjust itself to only use as much AC current as the computer is using at whatever time?
For example, say I have a computer that draws 150 watts of power for its use but it had a power supply that is rated at 450 watts. Would the electrical usage of this computer be 450watts, 150 watts or some other amount?
 

Answer:Power Supply Question

The power supply's energy consumption is directly related to the amount of hardware that's attached to it, therefore a 450W PS might draw a little more power than a 300W PS, but not necessarily depending on the PC's power requirements from the CPU and drives.

As per your example, I would expect the 450w supply to draw approximately just a little more than 150w.

The rating put on the supply is the max wattage drawn before the supply becomes overheated or unstable.

Nope. If your motherboard has a 24pin connector, and your PSU only has 20pins, it's not a good combo. Return the PSU before your computer suffers irreversible damage, and get the proper type of PSU.

Hello everyone ...

Although I am a huge PC enthusiast, I am building a different sort of machine that makes use of a typical PC Power Supply.

OK, I'll just admit it ... I'm making a food dehydrator ... and I need to rig some fans to facilitate airflow / convection.

Here's my idea: Use a powersupply, connected to several PC fans, to drive that airflow through the dehydrator itself.

My question: The main 20 pins connector (coming from the Power Supply) needs to have a jumper on some pins .... right? Which ones? How do I rig this puppy so it's stand-alone and powers the fans only?

Thanks!
 

Answer:Power Supply question

They are all posted on good power supply manufacturer sites... and in such books as Building and Repairing PC's.

The problem is that food properly handled in a dehydrator requires better, and more consistent airflow, and temperature controls, than any power supply I have seen can handle... leading to spoilage. You are likely to have quality control problems... no to mention insects.

That depends on what else is going to be in the system. If you are putting in a mid range graphic card then you will want a 400 watt psu. If not, then 350 would be fine. Also, its not only the watts that are important, but the amps on the 12 volt line that are important too.

350 watt HERE
