Make sure you dont get a no name brand PSU for a higher end system like that. I would say 650w minimum, despite what is reccommended as minimum by AMD.

A Corsair 650HX is a much better than average PSU. You be fine.

Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units.
