ATX-12V Power Connector
This connector supports the ATX power, functions such as modem Ring on, and
wake-up LAN and soft power off are supported by mainboard.
The power from PW1 should support at least 6.5A current for the use of P4 CPU. If
the power is not enough, the operation of CPU could be abnormal. Be sure the
power from power supply is enough, and don't share this power with other devices,
such as hard disk etc. You can use ICP's special cable for connection if your power
supply doesn't have suitable cable.
