ASRock 970DE3/U3S3 Motherboard
Either end of the SATA data
cable can be connected to the
SATA / SATA2 / SATA3 hard
disk or the SATA3 connector on
this motherboard.
Besides four default USB 2.0
ports on the I/O panel, there
are three 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 a
CD-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.
