Two HD 5870's in CF power supply question Tags: Graphics Cards Power Supplies HD Graphics Last response: December 9, 2010 11:37 AM in Graphics & Displays Share ambam December 9, 2010 5:46:56 AM I have Two GIGABYTE HD 5870's in CF and a Corsair TX850 850W power supply. Is 850 enough for these GPU's? The rest of my system includes a Core i7 930, 6GB DDR3 RAM, X58 motherboard, and a 2TB HDD. Should I have gotten a 1KW PSU?

Pair of 5870's will pull around 25 - 30 amps under load. CPU, about 10 amps. That leaves plenty of power for the rest of the system plus a healthy reserve. wa1 a c 189 U Graphics card a b ) Power supply December 9, 2010 11:37:05 AM ^+1 You have plenty power.
