That is a 6 pin power to the PCIe that some boards add for CF/SLI setups. It will not power the CPU at all.

supplementary power for PCI-e lanes, my biostar t-power n750 had a 4 pin molex for powering those lanes you do want to have 8 pin on your cpu power, a 6 pin pci-e power cable is not the same as a 2x4 pin 12 volt cpu power connector.

It would probably run OK, but I'd upgrade to an 8-pin PSU ASAP.

Just figured out something.I guess that a 4 pin is all you need.Some electric association requires the motherboard to have a bigger input of power just to be safe.And a 4 pin is all you need, I guess, as the wires can carry enough power to a 8 pin with a 4 pin.But i ma still upgrading my psu as soon as I get my sli setup in 6 months.

the six pin is optional, you could run with a 4 pin, but i dont recommend it myself.

The six pin is a PCIe connector, not keyed the same or wired the same as a 4/8 pin CPU power connector. The extra 6 pin connector is for PCIe slots if your running multi cards for extra power to the slots. If a board has a 8 pin CPU power connector, all are wired different. Some will work just fine with a 4 pin. Some will not boot at all with a 4 pin. Some will run fine, but you will have problems with a higher wattage processors, especially if your overclocking.

Research, research, research.

Next time read this guide if you have questions about pins. It tells you EVERYTHING you need to know about PSU and motherboard pins.
