Please connect the black end of SATA power cable to the power connector on each drive. Then connect the white end of SATA power cable to the power connector of the power supply.

Besides six default USB 2.0 ports on the I/O panel, there are two USB 2.0 headers on this motherboard. Each USB 2.0 header can support two USB 2.0 ports.

This header supports an optional wireless transmitting and receiving infrared module.

This connector allows you to receive stereo audio input from sound sources such as

aCD-ROM, DVD-ROM, TV tuner card, or MPEG card.

This is an interface for the front panel audio cable that allows convenient connection and control of audio devices.

1.High Definition Audio supports Jack Sensing, but the panel wire on the chassis must support HDA to function correctly. Please follow the instruction in our manual and chassis manual to install your system.
