I have a 4870 1gb that has 2 pci-e power connectors (i'm guessing both need to he plugged in?), and only one psu-> pci-e cable. In the box was a 2x4pin -> pci-e converter. But both 4 pins are male, and the modular slots on my psu are also male. So i bought another converter, that is 2 female -> male 4pin. Can i plug the two female 4 pins, into the PSU, then one of the 2 males from the 4pin->pci-e into the female of the _4pin male->2x4pin female_, and into the gfx card?
