I got an NVIDIA 760, which requires a 6PIN PCI and 8PIN PCI cable. I have a cable from a PSU that has both a 6 pin and a 6+2 pin PCI-E connector on it. The specs for this PSU say that it has 1 6pin and 1 6+2 pin connectors but I'm not sure if I can use them both at the same time, given that they seem to be on the same wire. Anyone come across this before?
