I'd recommend a good 650w or higher. Here is a good one if your low on cash:

On your average system the card requires you to have a 600 Watt power supply unit (more if you overclock). We recommend at least 40 Amps in total available on the +12 volts rails (accumulated).

600W w/ 40A on 12V rails. It isn't a hippy's card. (hope that doesn't offend anyone)
