8-pin ATX 12V Power ( PW12-P0-1, PW12-P1-1 )
PW12-1,PW12-2 , the 8-pin ATX 12V power connections, are used to
provide power to the CPU. Align the pins to the connectors and press firmly
until seated. You can plug in the extra 6 pin PCI-E power connectors
(optional) if you need them for extreme overclocking. It is not
necessary/required as the motherboard will function perfectly with just one
connector in each 8 pin socket.
