  1. A 7850 will only need a 500W PSU. Heck, even the CX600, which only outputs 480W on its 12v rail, can power a 7850 OCed.
  2. You only need 550w tops, get a XFX 550w core edition, if you want modular cords then just get a seasonic, XFX or corsair, you only need to get 550watts, whats the point in spending money when you don't have too?
