22) ATX Power Supply Connector (20-pin ATXPWR)

This connector connects 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 but gently making sure that
the pins are aligned.

on your system if your power supply cannot support the load. For Wake-On-
LAN, keyboard wake up, and suspend-to-RAM support, your ATX power sup-
ply must supply at least 720mA +5VSB.
