18A on the 12v rail isn't too bad. Looks like only low profile cards will fit though or I'd suggest a 4670. Anyway go with a low profile 4350/4550, or a low profile 9500GT.
the guy doesn't game and will be using the PC for work....you think he should get a 4670...your an idiot...I mean full fledged card carrying idiot...why do you even post your opinions on the board????
