Yes, you should be fine. That PSU should work with up to a 6950. Later on look into getting a modular 80+ unit: Antec, XFX, Corsair, Enermax, Lepa (re-badged enermax, with fugly fans), or Silverstone. Although I'd highly suggest getting rid of the Kingston RAM. Pick up: G.Skill, Geil, Corsair, or Mushkin.
