23) ATX Power Supply Connector (20-pin block ATXPWR)
This connector attaches to an ATX power supply. The plug from the power supply
will only insert in one orientation because of the different hole sizes. Find the
proper orientation and push down firmly making sure that the pins are aligned.
IMPORTANT: Make sure that your ATX power supply at least 10mA (750mA
recommended) on the +5-volt standby lead (+5VSB). Your system may become
unstable/unreliable and may experience difficulty in powering up if your power
supply is inadequate. For Wake-On-LAN support, your ATX power supply must
supply at least 750mA +5VSB.
