It's not that 2900xt needs 750w. I bet i could run it fine on a Tagan 580w fine, but not for long term.


That's the sort of comment has the PSU companies are laughing all the way to giga-watt land...

A single HD 2900XT will NOT need a 750/800w PSU, even after capacitor aging. I would be surprised if it needed any more than a quality 550w, seeing that you can run a single 8800GTX system off a 400w PSU and a pair off a 620w Corsair, NOT that I'm recommending doing either. My choice? 600w for the single and 800 for CF.
