20)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 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 720mA +5VSB.
