7) ATX4P1/ATX4P4 (PCIe Power Connectors)
The power connectors provide 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(s) from the power
supply to the ATX4P1/ATX4P4 connector to ensure system stability. For 4-way CrossFireX™, you must
connect at least one of the ATX4P1 and ATX4P4 connectors.
