11) Power Supply Connectors (20-pin block ATXPWR)
This connector connects to an ATX 12V power supply. The plugs from the power
supply fits in only 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 the ATX 12V power supply (minimum
recommended wattage: 230W) can supply at least 10mA on the +5-volt standby
lead (+5VSB). The system may become unstable and may experience difficulty
powering up if the power supply is inadequate. For Wake-On-LAN support, the
ATX power supply must supply at least 720mA +5VSB.
12) Power Supply Thermal Sensor Connector (2-pin block JTPWR)
The power supply thermal monitoring cable connects to this 2-pin connector.
Make sure to connect the cable to use the thermal monitoring feature of the
motherboard.
