I Like the CORSAIR TX650 V2 80 PLUS Bronze PSU. It's the same one I have, and it's been trouble free and quiet from day one.

I have the modular version of the Seasonic S12II - awesome PSU and sufficient for your PC. The Corsair TX650V2 is a great PSU...also made by Seasonic and is more than enough for your PC. That XFX is also a great PSU...also made by Seasonic. Get the least expensive of those three and be happy with a great PSU.

Stay away from Coolermast Extreme Power PSUs - they are complete trash. Also stay away from those HECs. The only Thermaltake that I would even consider is the TR2, but only if I couldn't get one of the above I recommended.
