Ok. I've told him about 100 times on techonvent, that he needs a (2) Molex to PCI express adapter. His PSU isn't PCI Express ready so it doesn't have a 6 PIN PCI express power cable from the PSU.
He bought the OPEN BOX version so the card came with nothing. One thing he needs is the adapter I mentioned above. He's currently using an adapter that has 1 molex with 4 pins to a PCI express 6 pin.
The adapter has (2) molexes. Both have 3 wires and 3 pins. The PCI express is 6 PINS. 3+3=6.
I really have no idea how I can make it any clearer.
