(1). ATX Power Input Connectors

This motherboard provides two power connectors to connect ATX12V power supplier.

NOTE: This 24-pin power connector “ATXPWR1” is compliant to the former 20-pin type. Pay attention to the orientation when doing so (Pin-11, 12, 23, and 24 should be left un-connected).

NOTE: For a heavily loaded system, a power supply that provides a minimum of 350W and 20A on the +5VDC rail is recommended. To support wake-up features, 2A on the +5VSB rail is required.

The auxiliary 12V power connector [ATX4P1] provides an additional power source for devices added on PCI Express slots. It is highly recommended to attach 12V power from the power supplier for the best system stability.
