This connector supports the optional wireless transmitting and receiving infra- red module. This module mounts to a small opening on system cases that sup- port this feature. You must also configure the setting through “UART2 Use Infrared” in Chipset Features Setup to select whether UART2 is directed for use with COM2 or IrDA.

14.ATX Power Supply Connector (20-pin block ATXPWR)

This connector connects to a 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 making sure that the pins are aligned.

IMPORTANT: Make sure that your ATX power supply can supply at least 10mAmp 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.
