I'm thinking that if he managed that kind of OC, then he must have enough power to the card. Man if mpilchfamily saw that he was using a 485W psu on an 8800gts regardless or amperage, he'd probably have a heart attack.
Well actually, I read today that a C2D system can run comfortably with one GTX
with a 470-500W PSU as long as the amperage on that PSU's rail(s) are more than ~30 and you dont have too many peripherals.
Please list full system specs and a detailed PSU explanation or at least give us the name of the PSU.
