18. ATX Power Supply Connector (20-pin 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 720mAmp.

This connector connects to a standard 5 Volt power supply. To connect the leads
from the power supply, ensure first that the power supply is not plugged. Most
power supplies provide two plugs (P8 and P9), each containing six wires, two of
which are black. Orient the connectors so that the black wires are together.
