550W to 650W should be sufficient, get one that is at least Bronze 80 certified. I've had good luck with Corsair PSUs.

Corsair 650W TX would be your best bet for that. You'd have enough headroom for OCing and upgrades with that - 550 would technically work, but you'd be cutting down on your headroom quite a bit, and the price difference isn't big.
