Emachines power supply upgrade

Question: Emachines power supply upgrade

I have an older eMachines Desktop PC model EL1360G which has a 200 watt power supply.
I would like to upgrade it to at least a 400 watt power supply.
Does anyone have a suggestion as to where or what I should buy? I watched a few videos on youtube on how to do the replacement but how do I know all the plugs on the new unit are the same and will fit? Because if they don't, I'll be more confused than I already am.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Emachines power supply upgrade

Check and make sure all the connectors are the same as the ones you have

I'm not certain if the image above is what you have but I'm thinking it is.

Image above looks to have:

1x 20pin+4pin (ATX Power)

1x 4pin (P4)

2x SATA power
Does your power supply have these and only these?

I am trying to repair an emachine that I believe has a bad PSU:

emachines T2682
2.60 Ghz Intel Cerelon
CD/RW 48x
DVD Rom 16X
56K Mdm
256 MB
3d Intel Extreme Graphics AGP

Replaced Power supply with an Antec 500 W Basiq model.

PROBLEM: Seeing that the previous power supply was dead so after installing the replacement I noticed that the Power Light just stays yellow. The processorfan does not turn on nor does my harddrive spin. However, if I unplug the IDE connection to the hard drive, the power HDD spins. I noticed when I power off the computer (by off switch on PSU - CPU power button completely unresponsive) the Processor fan slightly moves.

THOUGHTS: I've read several post on this site that point to bad PSU causing MoBo problems with the emachines. I chalked it up as the MoBo being dead, but when I saw the fan attempting to move I thought I could be incorrect. Any ideas?

This is my first post so I apolgize to all if this is not in the right place or forum.


Answer:EMachines Strikes again - Power Supply

The motherboard is bad and it will need to be replaced. If you can find a board that will accept the old CPU and memory you can save some money. You will need to use a separate Windows Operating System disc. Any eMachines discs will be useless with the new motherboard

Well, my son was on his eMachine W4065 happily playing Half-Life 2 when suddenly the machine went dead. He tried turning it on but nothing happened.
I unplugged everything and then shook the machine (part of my testing regimen) and heard something knocking around in the power supply.
I removed the unit and found a small black capacitor rolling around loose that had popped out of the circuit board. It had some scorching evident on the board.
Well, I ordered a replacement supply and am waiting on it now.
I checked over the main motherboard and nothing seems to be burned or broken. I gave it a close smell test (another part of my testing regimen) and nothing smelled fried.
I'm hoping all other components are ok and that when the capacitor killed itself it didn't take anything else with it.
Anyway, I guess all I have to do is install the new power unit, plug everything in and hope it runs ok.
Is there anything else I should do or try before start it up?

My friend's computer (T2825) died. Turns out no power. Swap the power supply out with 2 diff. known good P/S.. the system turns on for about 1-2 sec.. Are these Bestec ATX 250 -12E specicially pinned for an E-machines motherboard. looks like theres an extra wire on each side of the 20 pin connector..
Any help is appreciated..

Answer:Emachines t2825 power supply?

I'd say if there is an extra pin on each side of the 20 Pin ATX, you don't have the right PSU.

Bestec ATX 250 -12E looks to be a HP OEM PSU, while eMachines is owned by Gateway. So again I would question these PSUs as being a proper fit.

1 dvd writer

Is anybody familiar with this machine, and if so can you recommend a powersupply to fit?


Answer:Upgrading power supply in emachines T6410

If you are on a tight budget, then something like this would be good:

450W with 30amps on the (dual) 12v rails.

If you have a bit of cash lying around, this one is a bit more "future proof" (can handle future upgrades).
550W, with TRIPLE 12v rails totalling over 50amps on the 12v rails. This PSU looks amazing (just came on the market).

I was tinkering with my brother's PC, trying to take out his floppy drive because I needed one as mine doesn't have one. I did absolutely nothing with the power supply or anything, but for some reason the thing won't turn on. There's no indication of what's wrong with it; there's no light on the motherboard to indicate whether it's on or not, and the thing just doesn't turn on at all. So I don't know if the motherboard's fried, which I don't see how that could have happened, or if the power supply's busted, which I also can't see how that would have happened.Is this common for eMachines? Is there something I could have unplugged and plugged in wrong? There are three wires from the button on the case that you push to turn the thing on, and they were connected to a part of the motherboard. However, I don't know where exactly they were positioned (although I do know what they were connected to), but no matter how I seem to connect them, nothing seems to help. Would this be part of the problem? Where can I find a diagram or something of the motherboard? This is the one that he has: help would be appreciated, otherwise I have to buy him another PC.

Hey, I joined this forum because I am interested in doing a fair amount of modification to my current computer and I've got some basic questions to ask. I've got a eMachines T2825 PC and am interested in getting a GeForce 6800GT card to replace the one I currently have put in there, a FX 5700le. Doing so would require putting in a new power supply, but I'm interested in going further and buying a new case w/ power supply because for about the same price as a power supply I can get a better ventilated case that also should have a quieter fan (The current T2825 case heats up my upstairs room way to much and keeps those in the bedrooms around it up at night if I do not turn it off, while the other -older- eMachines here makes almost no noise and runs cooler to the touch...) My question is, how difficult would it be to transfer my system to a new case (I've done basic installation of cards and RAM, and know enough to indentify the hardware in there, but I've yet to tackle anything at this level; ) or would it be a smarter move to go for just a new power supply and card?

Answer:power supply upgrade

Hi hector 911. I have never heard of a power supply with an external 12V output socket. If you or someone you know is competent with a sldering iron and electronic components, then I would suggest taking an output from the 12V P4 connector that all ATX power supplies have these days, and feeding that via a suitably rated fuse to a connector at the back of the computer case. You should be able to find all the components you need at Maplin click here. But because of the amount of power available from an ATX power supply, this must be done by someone who is familiar with this kind of work.

From what I read elsewhere, you should still be able to use the power supply in question.  I personally did not try it, but others claim that you can use the pins on the 8pin connector that match up and let the others hang outdside the connector.  Some say, depending on the exact model of the Corsair PS, that the 8pin connect might be able to split.  Meant to split, not cut.

Hello Kelvin,

I suppose it depends on what new graphics card you are wanting to get to use with it. Some of the latest models (ex: GTX 480) can use around 295 watts themselves under full load.

Answer:Do I need OEM Power Supply to Upgrade?

Typically, eMachines never did come out with PSU's that were reliable.
Almost any standard replacement PSU in the 500w range will work just fine and give you some reserve power.

I replace PSU's in eMachines (and Dells) all the time and I've pretty well fallen in love with the Antec Earthwatts PSU's. I can buy them locally, whenever I need one, at the local Staples office supply stores.
Most will have the power switch on the back of the supply, although that's really not necessary, it comes in handy sometimes.

Good Luck,

Answer:power supply upgrade

What do you have now?
Think of your psu as the heart of your system. If you lose the psu, it can potentially take out everything. So obviously you don't want to skimp on it.

With a quality brand, it doesn't matter if its multi or single rail anymore, and your systems new enough any modern psu will be compatible.

Your current setup, with 5770, could easily run on 450ish W, so a 650W isn't too overkill, and allows for future upgrades.

I'd recommend a 650tx from Corsair... But they are pricey. - CORSAIR CMPSU-650TX 650W ATX12V &#47; EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply $89.99<-- Very good price, usually over $100 - Thermaltake TR2 TRX-650M 650W ATX 12V v2.3 &#47; EPS 12V v2.91 Modular Active PFC Power Supply $55 bucks after mail ins.

But basically paying over $75 before sales will give you a good psu.

Also remember, a quality psu can last multiple changes to your system

Answer:Power Supply Upgrade

I am system builder normally but decided to buy a Lenovo as a base to work from. I installed a PC Power and Cooling Silencer 750 in before I turned the thing on. I think my K230 had a 280 Delta, junk power supply. That is the most important piece in the machine in my opinion. You can always rely on Cosair and PC Power and Cooling supplies and they are readily available. Silverstone is another good option. I would lean toward Corsair or Antec for bang/buck and PC Power and Cooling for the ultimate supply. Its all preference and you can find good sales all day long. Also, you may not need 500 watts, as supplies are more efficient when you run them at a particular load so depending on what you are running on it you may only need 350-450 or another 250 but anything is better than what they put in there. Look for 80%+ efficiency and active PFC and you should be good, the one I have is one of the bigger supplies on the market and it fit fine with no modification so have at it and by all means I would!

Answer:Power Supply Upgrade

Here's a link for a PSU calculator. It will make a difference only if your PSU is too small for your system's requirements (or a low-quality PSU-some output much less power than rated as they get hotter). It won't harm anything if you do upgrade, though. JUst make sure it is compatible with your computer's mobo and will fit in your case.

I have a ThinkCentre M55 8810 low profile desktop and would like to upgrade the power supply to one that can handle some more power.  I was wondering if anyone had a suggestion for a power supply that would fit nicely in the case.

Answer:M55 Power Supply Upgrade

Measure the size of you current Power Supply Unit . Then go online to the various Power Supply makers and look up the size of their units. Make sure you have enough room at the end of the units so that you have room for the wires to go down into the case. My computer is a Thinkcentre M50 model 8189 and the case is a uATX or microATX. The original PSU (230 watts) has a jog to allow the room for the wiring and the CD player. I replaced the unit with a 600 watt unit, but I had to remove the existing CD player, but I was replacing it with a SATA DVD burner which is 1.5 inches shorter than the old CD player was, and it allowed me just enough room for the wiring. If possible go with a Modular Power Supply Unit then you only have to use the wires that you need. The one I looked at was 160mm long and I would probably have had to put the DVD burner in the lower slot to allow room for the wiring.

I have a Dell 5150 (purchased in 2005, so four years old) and the fan of my power supply is dead. My computer is running fine but obviously it is not safe to keep going without a fan. It came with a 305W power supply, very low-end as expected. I am therefore in the market for a new power supply but have heard some conflicting advice.

I did some research online and read from one source that it is perfectly safe to add, say, a 550W power supply even if you only started with 305W. The source stated that a power supply only uses what it needs to use, so putting in a higher wattage will not harm your computer, fry your motherboard, or overwork any devices. When I called Dell, who is not well-known for perfectly sound tech advice, I realize... they told me to order the exact same power supply the computer came with because that is what the computer was created to run with and that it would "fry my motherboard" if I tried to put a higher wattage power supply in there.

I also have a new video card, a NVIDIA GeForce 8600 GT. It requires a minimum 350W power supply, which Dell now says I will not have because it's 'dangerous.'

Who is correct? Is it safe to upgrade your power supply in an older computer? Why or why not? I'd like a yes or no but also a bit of an explanation if anyone is willing.

Hopefully someone here can help clear things up for me. Thanks in advance.

Answer:Can I upgrade my power supply?

What Dell told you is not correct. You can use a higher wattage power supply, and it will only use the power that it needs. A replacement power supply needs to be of good quality, needs to physically fit into the Dell case, and the power pinout for the 24 pin connector needs to match the motherboard (Dell used to use a non-standard pinout but stopped the practice a few years ago).

I am trying to find a more powerful psu for my HP Pavilion 7955. THe original psu is only 200w and it loads down . I have added a second HDD , a nVidia 256mb video card and a seconf DVD writer/player. It is obvious that the psu is under powered because I can here it labor under laod and the video card response to adjustments is very slow. The psu is a certain physical spec and I am having a hard time finding anything that will fit into the case. Any suggestions?
I was considering running two 200w psu's but would rather have a 350 or 400 w psu instead.

The computer only comes with a 460w power supply, with no option to upgrade. Is this a problem? For a quad core, 1gb video card, and 6-8gb of ram, I would imagine he would want a bigger one, at least to be safe. What do you guys think?

Answer:Need help on whether to upgrade power supply

If this is a custom build, then there should be no issues with upgrading the power supply.
It may run ok with 460W, but if it were me i'd get something better. probably 650w or better.

Hi, I want to upgrade my crap 300W ATX PSU to this one:
I don't know if it will fry my motherboard. I have an Amberine M Asustek mobo. Do I need an exact match? How can I find out if I can replace my 300W with this 500W? Is there a limit to the amount of power my motherboard can handle? Thanks in advance.

Oh yeah... It says on my 300W power supply something like ATX-300-12Z Rev: BD

Answer:How do I upgrade my power supply?

Just a word to the wise anything that is "FREE" is usually worth it!!!!!.........All 450 - 600 Watt ATX power supply's should work, the most important thing is the connectors as All PSU's put out the same voltages just the connectors vary in some cases.............Its a simply swap just disconnect the Computer from the Power Main(unplug) then open case and disconnect the connectors coming from the PSU to the HD's, MBO etc then undo a few screws and out pops the PSU, you can/should mark the connectors............I would stick with a Brand Name "Thermaltakes" are good and very reasonable in price, but there are plenty of others................That 500w PSU that goes for "FREE" has been going around the circuit for awhile, and have yet to hear anybody claim it is any good.

Answer:Power supply upgrade help

What makes you think it is too small?  Are you trying to upgrade something?No, it is crucial that you buy a quality unit from a brand such as Corsair, Seasonic, XFX.etc.  You should expect to pay at least $1 for every 10w that the unit is rated for.  Also, consider how much you actually do need, why 750w?  That is a lot for most systems.

Answer:power supply upgrade question

Let me guess. Did you get those "requirements" from the graphics card manufacturer?

The requirements are nearly always overestimated. The card manufacturers want to protect themselves in case a user buys a mediocre 500 watt power supply that can only supply 300 clean and reliable watts. Power supplies differ widely in quality. The claimed wattage tells you very little. They figure a lousy 500 watt unit might supply enough when a high quality 350 would be fine. Since the manufacturers can't know you are going to buy a good unit, they overestimate.

What graphics card are you thinking of?

Bestec is not a known brand. I would guess it is made by someone else and used by HP.

But it may be adequate, depending on what graphics card you want to use.

ATX power supplies should have all of the same external dimensions and will "fit". They vary in quality, power output, and the type and number of connectors. Which you will need depends on the equipment to be connected--hard drives, DVD drives, graphics cards, etc.

Hi everyone.

My original problem, i am sure is my power supply. However i would love a second opinion.

I have just upgraded to the cross hair V main board. My computer has been restarting randomly during intensive game play. it didn't do this before my upgrade. my PSU is 500w but ridiculously cheap.

Would you say it's the problem?

Secondly as i have said above i currently have a 500w PSU. I am thinking of upgrading to the antec High Current Gamer 750 watt.

I have filled in the system specs. do you think it will run my computer perfectly. also i will be getting 16GB DDR3 1600MHz RAM and an ATI 6970 will the antec PSU be enough?

I have done researchantec PSU seem's good but - recommended PSU for gpu is 750 and i think my mainboard is 600 so i arn't sure if i'm meant to add them up or just go for the 750.

Thank you all
I have tried multiple PSU calculators and found them to be shockingly awful

Answer:Power Supply Upgrade/Problem

It seems to me that without alot of peripherals a 500 watt should be fine. I never 'cheap out' on hardware so I wouild recommend Antec or Rosewill.

As to the random restarts it could be a PSU but I wouldn't rule out other issues such as heat.

I'm upgrading my PC & wondering if my current Corsair VX550 PSU is good enough. I've had it for approx. 4-5 years.
My new specs are:
Windows 10 Home 64Bit
Intel Core i6 6600k
8GB DDR4 Ram
ASUS Z170 Pro Gaming Mobo
3 x SSD (500gb, 120gb & 60gb)
500gb HD
ASUS Xonar DX Sound Card
I'm planning to OC the CPU a little.

Answer:Power Supply question for upgrade

No such processor as the i6. It can be i3, i5 or i7

Hello. I've tried looking for this info but couldn't find it anywhere.

I am about to upgrade to this:

Athlon XP 1800
Asus Mobo
256MB 2100 DDR

I already have this, which I'm keeping in the system:

40GB 7200rpm WD HD
GeForce 3 AGP Ti200 card
CL SoundBlaster Live XG
Some network card
ALOT of fans

My question is this:

I have a pretty good 300w PS which seems to have been trouble free for the year or so I have used it. Do I need a larger power supply and if so, what are some recommendations? I am trying to spend as little as possible since I am on a tight budget, but I do want brand name stuff.

THANKS for any info anybody can provide!!

Answer:About to upgrade and have Power Supply question

hey Max77Rave,

Unless you want to have to replace it down the road, I'd get at least a 400. They do not cost that much and you have got a bunch of power hogs in there.

Hi,I recently got my hands on a M91p SFF with:i5-2400 CPU8gb Ram250gb hdd @7200rpm2 tb hdd @5400rpmand 240w PSU What I want to do is to convert this machine into a [email protected] / 1080p gaming machine. My plan is to buy the MSI 1050ti lp and even though it seems to run on the 240w PSU I feel that I want to upgrade it to at least 300w to be safe and so that I can upgrade the ram to 16gb and maybe add an extra fan and a usb hub in the front, where the optical drive used to be, so that I can connect more than just two USB gamepads in the front.After some goggling I found this power supply: According to my measurements, is should fit. But I want to be sure, will this work in the case?Also, I think I read somewhere that Lenovo does not a use standard ATX connection, but from what I can see, this system uses a standard 24 pin ATX connection to the motherboard. I might be wrong though. I am no expert on computers and I have never upgraded or built a system before so I ask here to be 100% before I buy anything.  I hope someone where can shed some light on my situation. Thanks

I find myself needing to install an Nvidia GTX 970 into my T5500. The problem is the power supply - it only has two 6-pin PCIe power connectors, whereas the 970 needs one 8-pin and one 6-pin connector. I do have a Corsair TX750 v3 with four power connectors that can be configured as 6-pin or 8-pin. Can I just drop that in the T5500? Could I install a T7500 PSU, which I believe has the necessary connectors?
I seem to recall from reading other posts that this is possible, but I may lose the ability to add a 2nd CPU. Can anyone confirm this?

After finding out this pc has a low end graphics card i wanted to upgrade it, but as soon as i found out it had a 250 watt power supply, i started asking around on the internet to see if i could use a standard power supply, but i turns out i can't do that since this desktop requires a proprietary power supply. Could i just order a 500w proprietary power supply from lenovo?

My H520s with Intel i3 and integrated graphics - I understand it has a 180W power unit which is insufficient to upgrade to an AMD Radeon HD7570. I wonder if anyone is aware of a source for an upgrade power unit in the UK? Perhaps Lenovo themselves can supply as I believe they fitted some H520s with the mentioned card. Any help is highly appreciated.

Answer:UK sourced power supply upgrade

hi Johnc2,
As per checking page 48 of the hardware maintenance manual, the Ideacentre H520s supports the following PSU:
Link to picture
 Huntkey HK340-71FP 240W
If you want to give the machine more power, you can get a better TFX CPU (this item should work but I recommend you contact the seller for compatibility)
As per this article, the ATI Radeon HD 7570 only consumes 60W on full load so a 240W PSU should be sufficient.

I've got an older Gateway E4100 with an Intel D865GLC mobo and I've just upgraded my video card from a GeForce 5200FX to a 7800GS. The new card requires a power supply of at least 400W and my current PSU is only 250W. I plan on upgrading it but I cant find any information on what type it is. I'm assuming it's an ATX, but it doesn't say anywhere on the unit or on any of the system spec programs I've ran. If anyone with more experience can guide me in the right direction, I'd appreciate it very much. Also, it's 6x5.5in, so is that just a standard PSU size? Thanks!

Answer:Solved: Power supply upgrade.

Your motherboard is a mini ATX board. An ATX power supply will run it. However, it uses the older 20 pin power connector instead of the more recent 24 pin power connector. Just make sure the power supply you purchase is able to fit both 20 and 24 pin boards. You can also buy an adapter cable to adapt 20 to 24 pin, and 24 pin to 20 pin. I have seen some of the reliable experts on here recommending that you don't use the 20 to 24 pin adapters. I believe you might be safe adapting it from 24 to 20 pins though, but I will let someone with more expertise than me comment on that. I would buy a 24 pin power supply and adapt it for your board. That way, you have the newer technology. The power supply you buy should be the highest quality component in your machine. That is one thing you do not want to buy cheap. Good luck.

Hello, I have a friend who needs a PSU upgrade because he has a 220w and he doesn't have enough watts to upgrade his computer to a powerful LGA1155 gaming computer. He wants to upgrade his CPU because his CPU is less powerful than the G2020 and install a new GPU which I found him a GTX 750 TI by GIGABYTE so he can improve graphics in gaming. I found him the Intel Core i5-3330 which is good for gaming because that is a cheaper i5 CPU in the Ivy Bridge family and a GTX 750 Ti since I couldn't find any low profile GPUs that are newer than the 750 Ti. He needs like a 400w PSU that will fit in his computer and I tried finding one that will fit, but people are complaning about compatibility issues with the size of the PSU based off of reviews and comments in reviews. Is there any better CPU that can play games for his computer when he has 220Ws in his computer than the i5-3300 or is there any power supply with greater watts than the ones that I found on Amazon. Please let me know if you found a compatible power supply that will actually fit in his computer. Thanks-Brian

I have a FSP 250 watt (+3.3V 14A, +5V 25A, +12V 8A) PSU, AGP, and a single IDE hard drive. PSU measures 150 x 140 x 85mm (is this the standard ATX PSU size?).All the PSUs I've looked at have PCIe and S-ATA connectors. Can I use one of these (ie Is the PCIe thingy just an extra that I won't use?), or do I need to find a specialised AGP/IDE PSU?Confused! Advice needed.......

Answer:Power supply upgrade questions

most existing mobos have a 20 pin socket for the main power supply - the newer ones also have a separate 4 pin socket. The latest have a 24 pin socket. Check what your mobo has and then make sure that what you buy will fit. The atx is pretty standard these days. The higher wattage the better most are nowadays 400 to 500 Watts.

ANTEC SLK2650-BQE tower
350 WATT
Pentium 4 HT CPU
P4 Titan 865PE mobo
40G Dell harddrive from old tower Dimension 4600C
1GB Kingston RAM upgrade from 512 dell standard

I will start out by saying that I have not done any of the following.. I am only trying to help my hubby fix the computer before my credit card is maxed out from all the replacing!

This all started out as a "simple" graphics card upgrade to be able to play BF2 (to the ATI Radeon..umm the red one with the fan) sorry no specs. didn't check the size before leaving store and tower would not close after installation. However it worked fine. Then needed/wanted a RAM upgrade. bought a 1gb Kingston card for tower, got home and realized that power supply was not sufficient, went back out and purchased Antec tower. worked for one day. and then went out and bought the mobo listed above. It ran a little after that but then just shut down. (this was while heatsink was just sitting on CPU w/o fan) DUH! Now system will not power on. Have replaced CPU the with intel listed above. Now all that happens is the continuous beeping on start up. Obviously this is a power issue but where should I begin? Taking tower back to store tonight hopefully will do something. Thankfully we have 2 comps but mine will not be a party to this madness! Any advice would be much appreciated!!!

Answer:Power supply upgrade DRAMA!!!

if the hard drive is from the Dell it sint going to boot up and run on a different motherboard and CPU. you are going to have to do a format and reinstall windows. and your DELL XP disk isnt going to install on a non dell machine.

I have seen another post about this but it had no resolution - it also dealth with someone trying to make an incompatible power supply work with the desktop. Rather than do that, I am looking for a COMPATIBLE upgrade to the power supply in this unit (ideacenter 700-25ish). It uses a proprietary 10+4 pin motherboard connection, meaning it is not standard. If someone can direct me where to purchase a higher wattage powersupply that is compatible, I'd appreciate it.

Hi I have a HP PRO 3010 SFF for some reason literally over the last few day started to lag in certain games and online video streaming sites, the audio runs 100% perfect but the video just drags along not running at it's normal frames. Now as far as I know I have not done anything apart from install fallout 3 but even after that for 24hrs after it worked fine then all a sudden the games ran slow but audio was perfect, then I noticed youtube was doing it also, I also get a very glitchy and matrixy looking screen all in different colours. I as wondering if this was down to my power supply and whether I needed to upgrade it at all, if I do or should upgrade it which power supplies could I and should I use are there any recomendations?? I've updated all of the computer to windows 10 at the latest level, graphics card is updated at a loss on this???

Answer:HP PRO 3010 SFF power supply upgrade

SFF PSU's are not upgradeable due to the fact they are custom manufactured to fit into a small customized space, in other words they are non standard sized PSU's. I would look at other possibilities as to the cause like updating the video driver or increasing installed RAM.

Well, I've tried about 3 different power supply rating calculators, and I have had everywhere from 500W to 900W and I'm trying to figure out if anyone would have a better "guess".

I just bought a Dell Vostro 410 (Intel 33 MB/Intel Quad Core Q6600) 2GB DDR2 RAM and I am slamming 10 total hard drives (7200) (9 add) into it using 6 onboard SATA and an internal IDE RAID card. I also have a Firewire card (PCI), studio card (PCI), and a PCI x16 video card (ATI).

Anyone have a good guess what power supply I should actually have in this system to support everything? Any good brands that i don't have to worry about?

Also is there any rating for cooling fans besides the dimensions (cooling ability, noise)?

Answer:Power Supply Rating Upgrade

Welcome to MGs!! Man, that is some 'monster' you're building!! As for cooling and power, well, I'd take to your local ice plant for cooling and hook it up directly to your cities power source!!:-D Sorry, that was an ill-fated attempt at humor!! Anyhow, as for the PSU, there are alot of brand names out there that will give honest power, dependability and efficiency , Like Antec, OCZ, Thermaltake and others. Don't risk that machine with an off-brand PSU with questionable specs. You'd probably live to regret that. As for wattage, in my opinion, I wouldn't go less than 750w, but even more if you could afford it. Even 1000w wouldn't be out of the question, though that one may be a bit of 'overkill.' My problem is that I'd much rather have too much, than not enough.
As for fan 'ratings,' I don't know of any particular rating system, other than the lower the db, the quieter and the higher the CFM the faster it will move air in your system and more likely the noiser it will be. Trying to find a happy medium with what you're building may be a bit of a problem! However, I haven't built a machine in about a year, so there may be fans out there that can give you the best of both CFM, noise, and great cooling. Have you ever considered 'liquid cooling?' Good luck and if you need some links to some GOOD PSUs, I'd be glad to post some for you!!!

So I attempted to upgrade my power supply, from a Coolermaster atx12v 650 to a Thermaltake tr2-600nl2nc atx12v and found the new power supply defective after hooking it up and finding it unable to power my computer properly, lacking 6 of the requisite 24 pins necessary to connect to the motherboard properly upon close inspection, though not the wires, which is why I hooked it up in the first place.

However, now that the devil has been disposed of, the ghost still seems to remain in the machine. My restored power supply is very clearly powering all of the components of the computer, from hard drive, to fans to dvd, blue ray, hd, and all my other sundry drives. It is even providing power to my externals, though not all of them, as my mouse lights up, but not my keyboard. But something is not happening. The monitor is detecting the graphics card when power is in the computer, it makes a distinction between no connection and a connection when there is no power present. But no matter how I arrange the wiring, no matter how I test it, the computer acts as though it is booting, then behaves as though it has, but the speakers, monitor, and keyboard are quite insistent that it has not. Anyone know what I did to my computer?

Answer:Power Supply Upgrade Fallout

What i would probably do in this situation is disconnect every thing even the coms battery on the mother board let it sit for about 5 to 10 mins and reset it self.

Then plug in every thing one at a time.It might be a pain in the but it is all ways good to eliminate each items that could be causing the issue.

Hello, my computer model is the Acer VX2631 UR12. I recently purchased a low profile msi gtx 750 ti and ive been told that i need to upgrade my power supply or my computer might have a chance of dying because of the psu. If you guys could recommend me a psu that will be around 350-400 watts and that will fit and work perfectly with my computer, it would be greatly appreciated. thank you 

Answer:power supply replacement/upgrade

you posted this in the wrong forum. however I will say that the 750ti is not particularly power hungry, it draws around 40w peak from your power supply. If your PC hasn't already "died" then it'll probably be fine.

In order to prepare for future video card upgrade, decided for upcoming birthday to purchase newer power supply for my Asus M52BC_M32BC01 System, Found out Motherboard is M5A97 EVO 2, is there anything I should be aware of before doing the NEW Power supply install, plan on getting an EVGA at least 550watt G3 Modular Power supply, Current one is a Generic 350 watt from Asus

For future proofing I would personally go for the highest wattage PS I could afford.
