For a card like 6600GT with pentium D and 1 gb ram, 2 optical drive and 1 HD, BFG tech told me that a 400w psu with 19amps on the +12v rail is TOO low, and it is recommended to have 24 amps on the 12v rail. However, checking many decent PSU's, not many actually have 20+ amps on the 12v rail; unless I'm missing something, could anyone shine some light on this issue?
