22) 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.
