ATX4P (PCIe Power Connector)
The power connector provides auxiliary power to the onboard PCI Express x16 slots. When two or more
graphics cards are installed, we recommend that you connect the SATA power cable from the power supply
to the ATX4P connector to ensure system stability. For 4-way CrossFireX™/SLI, you must connect the
ATX4P connector.
