Hi, I am selling an older machine to a friend who wants to play older games, and as the prices of the 8800s have fallen (I can now get a used GTS for £30) I thought I'd pick up one of those to use in the system. Currently the system has a 420W PSU that supplies 16A to the +12V rail - is this enough to power an 8800 GTS as well as two hard drives and one DVD drive? Would it be worthwhile getting a 500W or a 550W PSU to use? Thanks.
