MS-9625 M-ATX Workstation Board
Power Supply
The mainboard supports SSI 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.
SSI 24-Pin System 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.
SSI 8-Pin CPU Power Connector: JPW1
This connector provides 12V power output to the CPU.

MSI Reminds You...
1. Maker sure that these two connectors are connected to adequate SSI
power supplies to ensure stable operation of the mainboard.
2. Power supply of 350watts (and above) is highly recommended for
system stability.
3. SSI 12V power connection should be greater than 18A.
