Well I've been looking for a PSU for a new system that is to run a 8800 GTS and have been finding very hard to find a PSU with enough curren on the 12v rail. A typical example is recommended above, the Corsair 520. I've looked at the spec of this PSU (and many others) and it falls very short, with a maximum, un-sustained current rating of only 18 amps on any of the 12v rails. As I said, am I missing something, or are the recommendations for any 400 watt PSUs a little misleading?
