I'm trying to hook up the Corsair AX850 to the Rampage mobo, but there seems to be a problem with the 8-pin 12V connector. The cables supplied by the PSU doesn't fit the 8-pin 12V socket on the Rampage. Has anyone ran into this issue?
I would post pictures to clarify, but don't have a camera atm.
You probably mixed up an eight pin PCIe connector with an eight pin CPU power connector. They are not the same and are not compatible. Most power supplies (assuming that this one is included, I'll have to check) that have an eight pin CPU connector have what is called a 4+4 pin connector, IE a 4 pin connector that has another 4 pin connector that can be attached to the first to form a single eight pin connector, that way it is compatible both with 4 pin CPU power motherboards and with eight pin CPU power motherboards. Check for such a connector.
