I am wondering, I've picked up a few more 6970's tonight. My power supply has failed me as it comes with 2 6+2 pins, 2 4 pin peripherals and about 10 sata supplies. I've been able to connect 1 6970 no problem, leaving me with 1 6+2 pin pci-e, 1 peripheral (after connecting my IDE HD) and 9 sata after connecting my larger HD. I've been able to connect 1 of the 6+2 pins to the second 6970 and have a single 4pin peripheral left over. The 8pin adapter that comes boxed with the 6970's has two female connectors per 1 8pin adapter. That seems like overkill in the case that each additional 6970 I add would require 3 4pin peripherals, 1 6pin and 18pin.
My question is, does the 8pin adapter (seriously?!) need 2 4pin peripheral connections in order to power these things? Or would 1 4pin peripheral supply enough power to the 8pin pci-e adapter. If it doesn't, this is either one ridiculous power sucking card or I'm missing something else all together.. Any help would be appreciated so that I could at least get the 2 cards running tonight. Otherwise I suppose I will just find a bunch of splitters tomorrow to keep well stocked.
