I just got ahold of a hold of a GTX 1080 with an 8 pin and 6 pin PCI-E connector. My old graphics card only had an 8 pin connector, and I do not have any extra PCI-E cables. Would a Y splitter be a good solution? or should I get another 6+2 PCI-E cable? In that case can anyone help me find extra cables, my PSU is a supernova evga G2 850.
