So I plan on making a PC build with two reference 980's due to their heat being blown out the back of the case. I also plan on using cables from Cable Mods, but the problem I'm having is that theres only 6+2 PCIe connectors, when the 980 only uses x2 6 PCIe connectors.What would I do with the other two pins, just leave them out? OR since they're individual sleeved just keep the 2 Pin PCIe part tucked away with the cable management?
