Please let me give the diagram for the how to connect front usb & sound connector in Gigabyte GA-K8VM800M Mother Board.

You need to compare the information in your motherboard manual for the Front Panel connections to the information in your case manual (or on the wire labels). Unfortunately, there is no industry standard for labeling, so they may not be exactly the same.

Your motherboard manual can be downloaded from here.
