Is 750W enough for 3930K OC'ed and 780 SLI?

I just bought a Seasonic 750W Gold

Currently I just got a 3930K and a GTX 780. I'm going to OC the CPU at least up to 4.2Ghz and then OC the 780 as well. I wasn't expecting it, but I'm thinking of adding another 780 for SLI in about a month or so. Is my PSU enough to last, or should I immediately return this and get a higher wattage?

    I would say yes. I've run an OC'ed 3570k and two 6870's on my XFX 750w and never had any issues, but I know for a fact someone else on here will say that you'll need more wattage when you really don't.

    The 750 X should handle it but to be honest I would feel better with an 850. Especially with the 3930K.

  3. 850w is more comforting

  5. Thanks for all the responses. I'll go for a 850W when I get my second 780, something like Seasonic 850W Gold. That way I can just swap out the PSU and not have to redo all the cable management (yay for fully modular!). I always go for Gold, "Go Gold or Go Home!"
  6. The X series are pretty much the power supplies all other are judged by. Just stick with them and you are fine!
