Help with AX1200i 8-pin connector for motherboard.

Hello, I just bought me a new Computer with a ASUS Maximus VII Hero Motherboard and a Corsair AX1200i power supply.



The problem is that I can not find a cable that fits EATX 12V 8-pin connector on the motherboard (ASUS Maximus VII Hero)



I got 2 cables with the PSU where it says "CPU" on one of the side of the cable and then i can fit it on the motherboard, but when I then trying to connect the other side of the cable it will not fit in the PSU, and then if I turn the cable around again it will fit the PSU but not motherboard, I got 2 of this cables with the PSU.



I have checked through all the cables that came with the AX1200i.



It's says "EATX 12V" next to the 8-pin connector on the Motherboard.



Anyone maybe have a solution or explanation on this?



Thanks for answer, Theoveturn ;)
