What plugs within here on my motherboard?

It's for additional power to the PCI X 16 slots.



Here is the encyclopaedia:

There is additional info on page 16. If you do a survey in the brochure for pcie, you will find more info on it as well.
the molex connector is for the PCIE

Plug a plug from the power supply into it

If you dont plug the power supply into it it wont boot up (same near the 4 pin plug over by the cpu)



Heres a link to what plug from the power supply go into it except it wont have the p6 printed on it
