This connector supports the optional wireless transmitting and receiving infra-

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. Use the five pins as shown on the Back View and
connect a ribbon cable from the module to the motherboard according to the pin
definitions.

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.
