ATX V2.03 power supply is strongly recommended for mainboard run-
ning with 2GHz or higher CPU.
To set up Power Supply on this mainboard:
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 model.
2. If you use an ATX Power Supply Version 2.03 or the later ones, you
can now connect the onboard 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 onboard 4-pin
Peripheral Power Connector to your Power Supply.
3. If you use an ATX power Supply of an older version than V2.03, there
will be no square-shaped +12V Connector. So please connect the
onboard 4-pin Peripheral Power Connector to the 4-pin Peripheral
Power Connector of your Power Supply.
