Here is the proof for my EVGA GTX 590 on EVGA's STOCK VOLTAGES! GPU1:0.938V, GPU2:0.925V =D
EVGA GTX 590 OC@775Core, 2000Memory
EVGA GTX 590 OC@800Core, 2000Memory
PC Power&Cooling 750w Continuous, 830w Peak rated @82% efficiency.
I have NO HARDDRIVE inside the Antec 900 Case to maximize Air Flow and minimize ambient temp.
Reverse the TOP FRONT FAN to suck the HEAT directly from the GPU1 exhaust (located at the end of the card toward the front of the case) out. I have 120mm FAN that draws cool air from outside the case directly on top of the GTX 590. Only thing inside is EVGA i790 ULTRA SLI Mobo, USB3 card, Q9450 @3.2Ghz, 4G DDR3 1600mhz 7-6-6-24-2T, 1 DVD-ROM.
