2.5 Power Supply

2.5.1 ATX 24-pin power connector

There are two 24 pin power connectors on the motherboard. Only one is needed to make the motherboard operational. The redundancy is built-in for your convenience; you may choose either one to hook up depending on the layout of your system chassis. The 24-pin connector provides power to the motherboard and the 8-pin connector provides power to the CPU. So both must be connected for the system to run properly.

Be sure to plug the power supply connector in the right direction. Failure to do so could cause damage to the motherboard.

Make sure your power supply can support at least 2 amps standby power for the Advanced Configuration and Power Interface (ACPI) functions.

Refer to the following diagram for the connector locations and orientations.
