    No.. You need at least 800w, 850w if you want headroom.

    thanks
  3. If you have a low power CPU you could run your setup bone stock, as that's a very high quality PSU. But it would be a shame to run a setup like that stock. What does the rest of your rig look like?

    Again, it might be a high quality PSU, but 650w is definitely not gonna cut TWO 780's.
  5. At stock it could, depending on the rest of his setup. Just like I said.
