Help connecting CPU connector from PSU to Motherboard

post #1 of 3
Thread Starter 
I have an MSI Z170A Krait Gaming 3X Motherboard and I'm trying to use my EVGA Supernova 750W P2 PSU, but when I go to connect the CPU connector from the PSU to the mobo, the pins don't match. There is an 8-pin port on the motherboard (see attached pic that shows pin layout from the MSI manual) and my PSU cable has 2 4-pin connectors, but one of the 4-pin connectors doesn't fit. It requires 2 square pins and 2 round pins per 4-pin connector, but one of the 4-pin connectors has all 4 round pins. My question is do I need to buy some kind of adapter, or can I just connect the 4-pin that fits, and leave the other side unplugged?

Here are some pics to hopefully explain better what my dilemma is.

It will fit. A "D" shaped thingy should go into a square hole.

I don't know why, but it seems it's the normal shape for the 8-pin connectors that can be split into 4+4 pin. Only when the PSU has an 8-pin CPU power connector that can't be split, it will have the shape you see on the motherboard.
