Is this PSU enough for i5 2500k+7970

My system specs-
Processor- i5 2500k OCed to 4.5 @ 1.33v
Motherboard- ASUS p8z77-M (Not pro)
RAM- 2x 4Gb G skill RipjawsX 1600 MHz CL9@ 1.5v
HDD- Seagate 2 TB green @ 5400 RPM and Seagate 500GB @ 7200 RPM
Optical Drive- Sony DVD writer
CPU Cooler - Noctua NH u12p SE2
Case Fans- total 5(including 2 fans of the cooler)

I am thinking about buying a Sapphire Vapor-x 7970 3GB and I hope to overclock it as well. I have no plans of tweaking voltage on the GPU.

Is my PSU enough to handle an overclocked i5 2500K and this sapphire vapor-x 7970? If not then I will have to settle with 7950 as I can't afford a new PSU along with a 7970.

P.S. I have no plans of Crossfire.

  1. Best answer
    I think you'll be fine, in tests the entire system draws about 400 450 watts at max load. So with a 2500k overclocked and that Seasonic PSU you'll have no problem running a single GPU.
  2. seasonic = awesome.
    have fun
  3. that system will draw less than 400w of power at max load so you will be fine.
  4. Thanks for all the replies. After reading replies here I have ordered the card. Can't wait to get my hands on this baby :-D.
