Hello. I am thinking of building a pc and was wondering if I got a 600w power supply and the video card I wanted used 500w. Would I need a new power supply?

Its better to have more watts on your PSU not less (that's not entirely true but it's the simple version). More than how many watts it outputs is the quality of the PSU. If you have a good quality PSU, then you'll be fine. If you have a Rosewill PSU or something, then I might worry 😀.

We really need you to list your full specs before we can help you out.

I do not know of any video card that uses 500W.

Most high-end gaming systems use no more than 300W total. I think migh-end graphics cards nowadays are close to 160W.

Whatever, I add up the total power and aim for 60% load unless I know I'll be updating soon.

I really dont get how a psu works. Would that leave 100w left for other things or is it thourghput to everything else?

that psu ^^ should be good.

what cards are you planning on using in SLI

 

[jdelsignore911]

gts 250, gtx 260, or gtx 275. Most likely the gtx 275 in the future not now though. Might hold off until Windows 7 and directx 11 to come out for my new build.

hmm yeah i'd say atleast get a 700w psu for that. u might not even need that much for the dx11 cards considering they will be built on a 40nm process(i think) which is cooler and uses less power

Alright.
1) What power supply should I get for a gtx 275
2) What power supply should I get for gtx 275 SLI
3) How do you dedicate a video card for PHYSX??? I heard some people talking about that.

1)Good brand psu, around 550/600 watts (good brands = corsair, pc power+cooling, antec, ocz, bfg)
2) start looking upwards to 700-800 i'd say (just an estimate)
3) all you have to do is put in your two cards (without sli bridge) and in the nvidia control panel, enable the correct card for physx only. never actually done it myself but its pretty straight forward
