I've seen plenty of people on various forums running an Radeon HD 7950 just fine on an EVGA 550W Core Edition (which puts out 528W on the +12V rail), even when paired with a 125W FX processor; it might have been a bit louder under load, sure. Various 550W Gold-rated units are slightly more robust, offering around 540-550W on the +12V rail, and they're frequently a step up in quality compared to Bronze-rated PSUs, though that isn't a universal rule. For instance, moving up to reliable 600W Bronze models—like those from Fortron—and anything above that would be a smart choice for an Radeon HD 7950.
Hold on. Looking at it this way, for an extra 150 bucks...$67 you end up with a much better power supply in the long run. It's just smarter.
