ASRock 990FX Extreme9 Motherboard
Besides four default USB 3.0
ports on the I/O panel, there are
two USB 3.0 headers on this
motherboard. Each USB 3.0
header can support two USB
3.0 ports.
This header supports an
optional wireless transmitting
and receiving infrared module.
This is an interface for the front
panel audio cable that allows
convenient connection and
control of audio devices.
