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.
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
Will 750W be enough or will i need a more powerfull PSU?
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.
