I pretty much agree - but see my "HOWEVER" below. But first, since it came with a 350W supply, I would not recommend a smaller supply. But you can certainly use a larger one with no problems which should increase your options considerable. This is because electronics only draw the power they need, not what the power supply is capable of delivering. That is, if the motherboard, RAM, CPU, graphics, drives, and case fans only need 300 watts, they will pull from the power supply 300W regardless if the PSU is a 350W PSU or a 750W PSU. And the PSU will draw from the wall just 300W, plus another 45 - 90 watts due to power supply inefficiencies - energy wasted in the form of heat.

HOWEVER, it does appear the Dell 540 came in a "slim" or SFF (small form factor) version too and in that case, you may need a TFX format supply. ATX power supplies will NOT physically fit the slim case! So in that case, you would need something like this 400W TFX PSU.

So we need the exact Dell model number of the computer, and preferably of the PSU too to be sure.

 

Hello all,
Thanks for all the replies.
I bought the pc second hand so have no documentation. The only detail on is Dell Studio 540. Now I'm not sure what size constitutes 'slim' but this case is appx 170mm wide and the psu fitted is appx 150mm wide.

Hello Evan, thanks for the info. I checked the link you suggested but I am not clear on whether I would get all the cables I need. On the 'semi modular' its not clear to see the various connectors and on the 'fixed cables' type it doesn't show any cables so I'm a bit confused.
Regards

 

Is the DVD/CD sideways (up and down) in the case or flat (left to right)? First picture or second picture?

 

ATX power supplies generally have the dimensions of 150 × 86 × 140 mm (5.9 × 3.4 × 5.5 in) so with your case being 170mm wide, it seems certain a standard ATX supply is what you need. And that is a good thing because your options are almost endless.

I do urge you to get a quality PSU that is from a reputable maker that is 80 PLUS certified to ensure at least an 85% "flat" efficiency rating "across all" realistic loads. I prefer Corsair and Antec PSUs, but understand achieving a high, flat efficiency requires quality design, quality parts, and quality construction - regardless the brand name stamped on the case.

Hello Evan,
I purchased the item you recomended but it doesn't come with 1x cable thats required. The one on the old psu is marked as a P2. Its a 4 pin item like the one in the bottom left hand corner of this link:

Is it something I can get from a pc shop or you advise where I can get one
Regards.

 

Check the big connector again. On newer PSUs, you often get a 24-Pin connector instead of the old 20-pin type. But because these new PSUs are typically designed to support 20-pin motherboards, the extra 4-pin is designed to be broken off the 24-pin so they can be used separately.

 

hello all, thanks for your replies.
I think I have resolved the plug issue. Following your comments I checked the various plugs and noticed a 6pin that had the clip offset from the centre so I reason that I can use that and it does fit.
However, I plugged it all up, switched it on and nothing.
I have checked and double checked fuses, mains electricty supply and cables all of which are fine. The thing is when I switch it on not even the psu fan is working, but surely should that not work even if the psu was only plugged into the mains power?
Regards

 

If the PSU fan does not work, I would look at the wiring from the case's front panel to the motherboard to make sure you have the front power switch connected to the correct two pins.

Note too that, depending on the power supply, the fan may not spin unless the PSU's temperature calls for it.

But if me, I would connect that PSU to my PSU Tester. These testers are not conclusive PSU testers because they do not test for ripple and other anomalies that affect computer stability, and they don't present a "realistic" load the PSU can expect when powering a computer. But they are pretty good in a pinch and will certainly test to make sure the fan spins.

Hello,
I have checked the front switch wiring and its all ok, it has never been touched or disconnected. This issue started when the pc wouldn't start after a shutdown. There just seems to be no power.
I am getting the old psu and the new psu tested tomorrow but in the meantime, assuming that the psu's are working and are not the problem, can you advise anything else that could cause the pc not to start up.
Regards
