Hardware Setup

Power Supply

The mainboard supports ATX power supply for the power system. Before inserting the power supply connector, always make sure that all components are installed properly to ensure that no damage will be caused.

ATX 24-Pin Power Connector: ATX1

This connector allows you to connect an SSI power supply. To connect the SSI power supply, make sure the plug of the power supply is

inserted in the proper orientation and the pins are aligned. Then push down the power supply firmly into the connector.

You may use the 20-pin ATX power supply or 24-pin SSI power supply as you like. If you’d like to use the ATX power supply, please plug your power supply along with pin 1 & pin 13 (refer to the image at the right hand). There is also a foolproof design on pin 11, 12, 23 & 24 to avoid wrong installation.

MSI Reminds You...

1.These two connectors connect to the ATX power supply and have to work together to ensure stable operation of the mainboard.

2.Power supply of 350 watts (and above) is highly recommended for system stability.

3.For ATX 12V power connection, it should be greater than 18A.
