27)ATX Power Supply Connector (20-pin block 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 (minimum recommended

wattage: 200 watts; 235W for a fully-configured system) can supply at least 20 amperes on the +5-volt lead and at least 10mA (750mA recommended) on the +5- volt standby lead (+5VSB). Your system may become unstable/unreliable and may experience difficulty in powering up if your power supply is inadequate. For Wake- On-LAN support, your ATX power supply must supply at least 750mA +5VSB.
