Ahh, so the whole system is using up 170-200W?

That does make much more sense than the single card using 200W+.

So how can we know how much power is being used up by the the card itself?

A combination of guessing, estimating by using TDP and the occasional reviewer that can measure actual power consumption like the guys over at xbitlabs is how I do it .

In that case, 500W should be more than enough for the OP.

Sorry for mixing things up guys.

Not necessarily. The Antec EA500 has 34A on the 12V (408W). If each 8800gs uses 70W peak plus add ~65W for the CPU, ~30W for the chipset and another amp or two for HDDs and fans in a worst case scenario the PSU would definitely be loaded quite heavily. It not really something I would do, especially in a setup that will be at peak load constantly as would be in a folding rig. Something with at least 40A on the 12V would be more appropriate.

The 550 and 650TX are only $2 apart on the Egg.

It is WAY over what he had originally intended to spend, but really the only units with 40A+ for that price.

Although he'd be cutting it close, I think he can get away with 33A.

dont worry about OCZ rebates, tehy are the best when it comes to them. They send you an email link when they receive it and in the link is a page with your rebates status on it. Definetly get an OCZ StealthXStream, i cant even hear mine when i put my head up next to it!
