I'd like some recommendations on 600-650W PSUs please.
Alright, but before that tell me, you're going to use only microcenter as the place where you'll be buying? Because I'd rather do it at Newegg or NCIX.
Anyway...here's my personal recommendations for you: get this
. These two are quite solid choices (for your money, that is) that will completely satisfy your demands.
If you can get them from microcenter, then it's fine. I just don't like microcenter because usually it has boring and rather small menu.
