EPS 8-pin 12V Power (PWR 8P1)
EPS PWR 8P1, the 8-pin ATX 12V power connections, is used to provide
power to the CPU. Align the pins to the connector and press firmly until seated.
The secondary is optional for improved overclocking. Please remember to
make sure that the tab on the EPS socket is aligned with the release clip on the
cable, because if they are on opposite sides, while it will be able to fit, it is the
incorrect cable and may damage the board, as that is a PCI-E 8pin cable.
