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.

Okay guys thanks, can I run it with a 4 pin and my low power 240 that takes all its power from a pcie?

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.

I think it will run with a i3, only 65w I think.
