12. ATX Power Supply Connector (ATX, 20-pin block)
This connector connects to a 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 can supply at least
10mAmp on the 5-volt standby lead (+5VSB). You may experience difficulty in
powering on your system if your power supply cannot support the load. For
Wake on LAN support, your ATX power supply must supply at least 720mAmp.
