11.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 but gently making sure that the pins are aligned.

IMPORTANT: Be sure that the ATX power supply can take at least 10mAmp load on the 5volt standby lead (5VSB). You may experience difficulty in power- ing on your system without this.
