Well yeah, but the question here isn't "will a 650W PSU be maxed out with 2x 6950's", but rather "is 650W enough for 2x 6950's", and clearly it is or else I shouldn't be able to play games....

If he had asked, "my 650W PSU runs two 6950's without a problem, but is it bad to be maxing it out? Should I get a larger PSU?", then that'd be a different story rolleyes.gif

Often here people overlook the actual question and instead opt to offer their irrelevant opinions rather than actually answering the question, and not sure if it occurs more in this section, but I sure see it a lot here. We all know a quality 650W will be fine with two 6590's, so why not just say that instead of voicing opinions that I doubt the OP gives a rodent's rectum about smile.gif

You do realise that he runs a 2500K which will not pull more than ~150W at <1.5v(that already benching conditions and well above 5Ghz clocks).. we're not talking about a high voltage tolerance, high leakage Nehalems here, which can pull 300W when heavily overvolted(bear in mind that's also a pretty rare scenario considering the cooling required to dissipate this kind of heat).

You're working with false knowledge and a lot of misconceptions, give this thread a read for some proper info on actual power draw.

xD I kept my order for the Corsair AX850 watt and it got delivered today =D I might be able to get away with the 650 watt, but I do plan on overclocking them and I want to be on the safe side. If it ends up being overkill then eh.

There's nothing wrong to buy insurance and have a peace of mind. At the end it's not about $$$ but the headache and data lost should something got burnt.

PSU is one thing not to skimp on, especially considering the narrow price range a lot of the higher quality models occupy. What you need to have, what you want, and what you can afford can usually all be accommodated unlike a lot of other hardware. AX850 is a good unit, I run one myself (although if I was in the market right now I would not choose it). It gets a little out of hand with people buying 1500w silverstone striders for single GTX 580 builds and such sometimes, but running 200w over what you suppose you could max out at is fine by me thumb.gif

a 650W would be cutting it close.
