This requires an external detection mechanism such as a chassis intrusion sensor or microswitch. When you remove any chassis component, the sensor triggers and sends a high-level signal to this lead to record a chassis intrusion event. By default, the pins labeled "Chassis Signal" and "Ground" are connected to the front panel microswitch. If you wish to disable the chassis intrusion detection feature, unplug the cable from the microswitch and place a jumper cap to these pins.

Devices communicate with an SMBus host and/or other SMBus devices using the SMBus interface. SMBus is a specific implementation of an I2C bus, a multi-device bus that allows multiple chips to connect to the same bus and enable each one to act as a master by initiating data transfer.

ATX power connectors (24/20-pin ATXPWR, 8-pin CON12V) These connectors connect to an ATX 12V power supply. The plugs from the power supply are designed to fit these connectors in only one orientation. Find the proper orientation and push down firmly until the connectors completely fit. In addition to the 24/20-pin power connector, this motherboard requires that you connect the 8-pin +12V power plug to provide sufficient power to the CPU. Make sure that your ATX 12V power supply can provide 8A on the +12V lead and at least 2A on the +5-volt standby lead (+5VSB). The minimum recommended wattage is 230W, or 300W for a fully configured system. The system may become unstable and may experience difficulty powering up if the power supply is inadequate.

CPU, Chassis, and Power Fan Connectors (3-pin CPUFAN1, CPUFAN2, SYSFAN1, SYSFAN2, SYSFAN3) The fan connectors support cooling fans of 350mA~740mA (8. 88W max. ) or a total of 1A~2. 22A (26. 64W max. ) at +12V. Connect the fan cables to the fan connectors on the motherboard, making sure that the black wire of each cable matches the ground pin of the connector. Do not forget to connect the fan cables to the fan connectors. Lack of sufficient air flow within the system may damage the motherboard components. DO NOT place jumper caps on the fan connectors!
