11)Power Supply Connectors (20-pin block ATXPWR, 6-pin EAUXPWR) These connectors connect 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)SMBus Connector (5-1 pin SMB)

This connector allows you to connect SMBus (System Management Bus) devices. SMBus devices communicate by means of the SMBus with an SMBus host and/or other SMBus devices. SMBus is a specific implementation of an I2C bus, a multi-device bus that allows multiple chips to connect to the same bus and enabling each one to act as a master by initiating data transfer.
