I just got a evga gtx 1070 and I received a power connector which is 2x6+1 female to 1 8 pin male which connects to the gpu. The problem I'm having is that the 8 pin part doesnt fit into the gpu socket, it just slides halfway in and doesnt click. I can use my psu 6+1 instead but I wanna know why they included a 2x6+1 to 8 pin connector. Does this gpu require more power? If i just use a single 6+1 connector from the cpu wil it bottleneck or soemthing pls help I'm new to this computer stuff
