Plug the Q-Connector into the associated pins on the motherboard. If you
look closely at the bottom of the Q-Connector, you will see that most of the
pins have corresponding holes but a few are covered. This is done to force
you to correctly align the Q-Connector to the pins on the motherboard.
Next up are the wires for the front-panel audio jacks. This is a bit easier as
these wires are already attached to a plug labeled HD AUDIO. Locate the
corresponding plug on the motherboard (toward the bottom-left corner) and
connect the HD AUDIO plug. Like the Q-Connector, the HD AUDIO plug
connects only one way. Verify your plug orientation with the following figure.

motherboard
Another important cable to plug into the motherboard from the PC case's
front-panel ports is the USB 3.0 cable. Plug the end of this cable into the
20-pin USB 3.0 connector located toward the upper middle of the right side
of the motherboard. Refer to Figure 30, The 20-pin USB 3.0 connector on the
MOBO , on page 35 .
Last, we need to connect the wires from the two fans on the front of the PC
case to the motherboard. In addition to helping circulate air around the
interior of the PC case, these fans have LEDs that can be lit strictly for pre-
sentation purposes. You can toggle these lights on and off via the lamp button
on the PC case's front panel. You can also increase fan speed via a three-
position slider switch to the right of the lamp button.
