SLI Gigabyte GTX 570 OC Power supply

Hello im thinking of upgrading my Computer with a new motherboard what supports SLI. So I can get a second Gigabyte GTX 570 OC. But im not to sure that my 750W PSU can handle it.
My specs
CPU I7 2600
EVGA Intel Z68 SLI Micro Intel Mainboard - LGA 1155
16GB 1333mhz RAM
2x 2TB 7400RPM hard drives
Bluray/dvd optical drive
two Gigabyte GTX 570 OC's
PSU 750W.
Will 750W be enough or will i need a more powerfull PSU?

  1. A good quality brand 750W PSU would be fine, what is the make and model of your PSU?
  2. woops i actually meant 650Watts* 650WT MASTER Modulator: ATX 650WT
  3. 200W at max load. More if o/c'ed and double when SLI'ed. Figure 400W to be safe, ya' never max load like Furmark, that's 34W total power consumption for the video alone. A good 750W PSU should do it. Get one with 4 ea. 6+2 pin plugs and at least Bronze certified. With the $$$ you're already talking about damn sure don't skimp on a PSU.
  4. Are you referring to a CoolerMaster 650W modular PSU?

    Do you by any chance have a link to the product?

    I cant find a review for the 650W model but the 600W model doesn't look good at all

    They had trouble pulling 450W from the unit : /

    I personally wouldn't risk it
  6. ok Thanks guys.
  7. What's a Master Modulator:ATX 650WT? Sounds like something in a peep show.
