I’ve just purchased a EVGA 2070 XC. My PSU is a Seasonic 550w Focus+ Platinum. The GPU requires a 8 pin and a 6 pin. I haven’t been using a GPU that has required extra power recently so had a look at what cables there were. There’s only the one PCIe cable that has dual 6+2 pin connectors. Is it ok to just use the one cable for both connections?
