Best 2 choices:
 
1) PC Power and Cooling 750 Silencer (Usually can find for $135 with a good search for best price)
 
2) Corsair 750TX or 650TX (Since you are not going to SLI anyway)
 
Forget about the OCZ (They now own PC Power and Cooling, which is there premier PSU branch of the company).
 
Remember, don't cheap out on the PSU just to save a few bucks, it's one of the most important parts, and can later on be reused in future builds.

Agreed. Go with the PP&C or the Corsair.

I own a corsair 450VX and it's very good.
if you want a decent quality cheap keyboard get this

I've been using it for a while for gaming and it's worked great but it doesn't have any macro keys or any such stuff
