Corsair vx550w / Crossfire


Recommended Posts

In an older previous message I think I said I would never run crossfire, but I think I might in future now, but have a question.


I own the Corsair vx550w power supply. And on the Sapphire website for their 3870 card, they list this for its requirements:



"# 450Watt or greater power supply with 75 Watt 6-pin PCI Express power connector recommended.

# For ATI CrossfireX: 550 watt power supply or greater with two 6-pin connectors. "



I was wondering what that 75watts would translate to in amps on the 12v rail? And does anyone have any idea how many amps would they require for crossfire?
