Am I going to kill my 125w PSU?

[liljone]

This is a noob question but here it goes. On this dell system XPS410 I realized I had a 125w PSU. I'm running a Nivida 7950 GT OC with no problems (added after I bought the system). The system min for this card for 1x card 300-400w~ PSU. Every thing works grate at the moment but is wear and tear from the full load from the video card going kill the PSU overtime? I went to dell's web site to look at a better PSU and all they had for my model was this 350w refurbisher PSU for $135!!! (over priced for the lose!!).

Am I going to kill my 125w PSU? Thanks for the help.

p.s. a standard ATX PSU wont fit this case, the PSU is half the size. (**** dell never will buy one again, did not have money for a build should of waited)


sorry for my noobish.

That's why you should never buy a branded computer

Well go on and buy a Psu on newegg.
For $50 or $60 you get a quality psu.

I do not think you have a 125 watt PSU. Did not sound reasonable. I googled "dell xps410 psu specifications" and several sites said that particular computer series has a 375 watt PSU.

A stock 7950GT needs about 60 watts; OC'd probably no more than 75 watts.

High side estimate of your power requirements:

CPU: 7 to 8 amps, call it 90 watts
Motherboard: 12 volts @ 1 amp, 5 volts at 3 amps, call it 30 watts
2 GB memory: 3.3 volts @3 amps, 10 watts
Hard drive and DVD burner: 50 watts
Video card: 75 watts
Sound card: ???

That's about 250 watts without the sound card. Add 20% for Mr. Murphy and your 375 watt PSU should be adequate. If you start seeing random resets/reboots under heavy graphics loads, then plan on replacing the PSU.

Would a higher quality, more powerful PSU be better? Certainly. But, in the absence of problems, what you have should be good enough.

If you do need to replace you Dell PSU, PCPower sells replacement PSU's that fit Dell systems.
They are cheaper too.
