I just brought a new Nvidia GTX 760. I see that there are 2 connections, one for a 6 pin and another for an 8 pin PCI E connector. On my power supply I only have one wire for a PCI-E connection. However it has split ends both of which are 6+2 pin connectors. My question is would it be ok for me to connect these 2 to my GPU even though they both originate from the same wire, or do the PCI Connecters have to be from separate wires?
