This is not a problem, and as it sounds, is not used in your system.

Some video cards have such huge processing power that they need thier own supply, as it would draw too much current from the motherboard otherwise. Below is a web site which reinforces this information, and gives an explanation of each connector.

Or do I not understand you. Do you have one less, or one too many?

There are no wires, it's a big hot-swap plug.
