Is my PSU sufficient?

I'd like to be able to overclock my 2500k to about 4.3 GHz, and maybe clock my 570 a little bit higher, but i'm worried about my power supply, i have a corsair ax 750w, and i was wondering if it would be okay to overclock? i also have 6 case fans, a dvd drive, and 2 hard drives (if that makes a difference)
Thanks

    Well, here is one free online psu calculator:

    There are others, I am not sure which is most accurate. Corsair is solid for psu's, 750watts should be more than enough for one 570 overclocked. How many 12v rails does that psu have, and how many amps per 12v rail?

    Looks like your psu is 80plus Gold certified, with one +12v rail and 62amps. That is quite good, I believe. Should have no problems at all running what you are currently thinking about.
  2. You have nothing to be concerned about with oc'ing your rig with that psu.
    It could handle 570 Sli no problem.

  3. Goodness, yes. A good 550 watt PSU will handle your system as long as it has only one GPU.
