I have a Raidmax 730w power supply, and its modular. there is only one plug in for a 6 pin, and the cable has 2 different 6 pins on the same cable. Will this cable be able to run 2 different video cards running XFire? or will is also be able to run say a 6870 that requires 2 6 pin connectors?
You should be able to feed two cards that each require 1 6/8 pin PCI-E power source... or 1 card that requires 2 6/8 pin PCI-E power source. A cable with 6 pin provides 75W power to the card. With the 75W available on the PCI-E x16 slot, that would be a 150W supply. 2 6 pins will up the available wattage to 225W. Cards that require a 6 pin and 8 pin are 300W cards. Your cable/PSU port is designed to provide any of those combinations of power to the videos card(s).
