Connecting the USB Ports

You will find a single 10-pin connector on a cable attached to the front USB ports. This Intel standard connector is keyed so that it can’t be accidentally reversed as long as it is connected to a proper Intel standard motherboard header. Connect the 10-pin connector to the motherboard headers so that the blocked pin fits over the missing header pin.

Note: Please check the motherboard manual for the USB header pin layout and make sure it matches the table below. If it does not match this Intel® standard, please visit Antec’s web store at http://www.antec.com/StoreFront.bok and search for part number 30095 to order a USB Internal Adapter Cable. This adapter will allow you to connect the front USB to your motherboard on a pin-by-pin basis.

Connecting the Audio Ports (AC’ 97 and HDA)

There is an Intel standard 10-pin AC’ 97 connector and an Intel 10-pin HDA (High Definition Audio) connector. You can connect either the AC’ 97 or the HDA connector to your motherboard depending on the spec of the motherboard. If your motherboard supports Intel’s standard onboard AC’ 97 audio connector, you can plug the AC’ 97 connector directly into the board. If your motherboard supports Intel’s High Definition Audio, you can plug HDA onto the board. See instruction below:
