ATX V2.03 power supply is strongly recommended for mainboard run-
ning with 2GMHz or higher CPU.
To set up Power Supply on this series:
1. Connect the on-board Main Power Connector (20-pin) to the Main
Power Connector (20-pin) of an ATX Power Supply which can be
either of the latest version 2.03 or of earlier ATX format.
2. If you use an ATX Power Supply Version 2.03 or later, you can now
connect the on-board square-shaped +12V Connector to the square-
shaped +12V Connector of your ATX Power Supply. In this case, it is
not necessary for you to connect the on-board 4-pin Peripheral Power
Connector to your Power Supply.
3. If you use an ATX power Supply of an older version than V2.03, you
cannot find a square-shaped +12V Connector with your Power Supply;
you must then connect the on-board 4-pin Peripheral Power
Connector to the 4-pin Peripheral Power Connector of your Power
Supply.
