Haswell-E plus GTX 1080ti - 750 watt psu?

System in sig, except my Corsair HX850i just died without warning. Also replaced dual GTX 980 with a single GTX 1080 Founders Edition.

I have a spare HX750i which I am using and system works fine but I have not tried overclocking.

Is the 750 enough if I want to moderately OC my CPU?

System is like two HDDS, one solid state drive, Haswell E, 16 GB ram and the GTX 1080ti.

Is 750 watts enough?

Yes, have you picked one? I'm a fan of the EVGA P2 750
EDIT: I didn't read carefully, you already have a 750, ha!


For your specific system, you can calculate using this: http://www.coolermaster.com/power-supply-calculator/

650 watts would be enough for your system overclocked. Your HX750i will handle it without issues.

Agreed. My current system is running on a 650 without issues and is heavily overclocked.
