As many have stated already, 600W is going to be plenty.

 

This is my system power draw, from the wall socket, with Prime95 and Unigine Heaven running simultaneously.

I have all the power-saving features disabled...so the CPU and all is going at full speed all the time.

System specs:

  • FX-8350 @4.8GHz 1.4V
  • Sapphire Radeon HD Dual-X 7970 (aka R9-280X) @115 /1500 with ~1.3V
  • ASUS Crosshair V Formula motherboard
  • 2 x 120GB SSD's + 1TB WD Black HDD
  • 8 fans in total (including the two on my CPU cooler). Out of the 8, 5 are LED's.
  • Corsair TX850 (v1)

542W from the wall and an 80 PLUS Bronze Power supply...which is about 85% efficiency at 50% load. That means it's about 460W that is actually being used by the system.
