ATX V2.03 Power Supply is strongly recommended running with the
nFORCE2-chipset mainboard.
To set up Power Supply on this mainboard:
1. Get ready a V2.03 ATX Power Supply which provides a square-shaped
+12V Power Connector in addition to the 20-pin Main Power
Connector and other peripheral power connectors.
2. Connect the on-board square-shaped +12V Power Connector to the
square-shaped +12V Power Connector of the Power Supply.
3. Connect the on-board 20-pin Main Power Connector to the 20-pin
Main Power Connector of the Power Supply. Please note that both
the +12V Power Connector and the 20-pin Main Power Connector
should be connected to Power Supply to power on the system.
