Hardware Installation
F. ATX12V Power Supply
The power supply connector is the last connection to be made while
installing a motherboard. This motherboard requires an ATX 12V power
supply (For P4 system), an AT or ATX power supply cannot be used. We
recommend a power supply of at least 350W, or 400W under full loading.
Steps:
1. Connect the 20 pin connector to the ATX power connector. See FIG. 1.
2. Connect the 4 pin connector to the +12V power connector. See FIG. 2.
Note1: The presence of the +12 V power connector indicates
that a power supply is ATX12V; the absence of the +12V
power connector indicates that a supply is ATX.
Note2: When using the Power-On by Keyboard function, please
make sure the ATX 12V power supply is able to provide
at least 1220mA on the 5V Standby lead (5VSB).
