Hi have a new computer to build. Everything is in and connected apart from one thing. The CPU connection from the Power Supply. They are totally different and I don't have a clue why? It completely will not fit. It does split into two 4 pins but it clips back together to make a 8 pin.

Motherboard is a Asus Z87-Pro

Power Supply is a Corsair GS700

any help would be greatly appreciated
