13. ATX Power Supply Connector (20-pin ATXPWR)

This connector connects to a 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: Be sure that the ATX power supply can take at least 10mA load
on the 5-volt standby lead (5V SB). You may experience difficulty in powering
on your system without this.
