19) ATX Power Supply Connector (20-pin block ATXPWR)
This connector connects to an ATX power supply. The plug from the power sup-
ply 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 can supply at least 10mA
on the +5-volt standby lead (+5VSB). You may experience difficulty in power-
ing ON your system if your power supply cannot support the load. For Wake-
On-LAN support, your ATX power supply must supply at least 720mA +5VSB.
