11) SMBus Connector (5-1 pin SMB)

This connector allows you to connect SMBus (System Management Bus) de-

vices. SMBus devices communicate by means of the SMBus with an SMBus

host and/or other SMBus devices. SMBus is a specific implementation of an I

bus, which is a multi-device bus; that is, multiple chips can be connected to the

same bus and each one can act as a master by initiating data transfer.

12) Internal Microphone Connector (3-pin MIC2) (optional)

This connector supports the chassis-mounted microphone to the motherboard

instead of connecting an external microphone to the ATX connector.

NOTE: The internal microphone does not work if there is an external mi-

crophone connected to the external Mic (pink) jack. You may only use one

microphone at a time.
