FDD (Floppy Disk Drive Connector)
The FDD connector is able to connect a single floppy disk drive via a FDD cable. Usually one
edge of the FDD cable is marked in red, please attach this marked edge to position 1 on the
connector.
IDE1 / IDE2 (IDE1 and IDE2 Connector)
The IDE connector is able to connect two IDE devices via an IDE cable and requires checking
of the IDE jumper setting. It is recommended that the hard drive be connected to the first IDE
connector while the optical drive be connected to the second IDE connector.

CPU_FAN (CPU Fan Power Connector); SYS_FAN (System Fan Power Connector)
The cooler fan power connector supplies a +12V power voltage via a 3-pin/4-pin(only for CPU_FAN)
power connector and possesses a ful-proof connection design.
Most coolers are designed with color-coded power connector wires. A red power connector wire indicates a positive connection and requires a +12V power voltage. The black connector wire is the
ground wire (GND).
Please remember to connect the power to the cooler to prevent system overheating and failure.
Caution!
Please remember to connect the power to the CPU fan to prevent CPU overheating and failure.

SATA0/SATA1 (Serial ATA Connector, controlled by ICH5)
The SATA0/1 connector is able to connect a single Serial ATA device via a SATA cable.
For the connected SATA hard disk to work correctly, please check the related BIOS setting
and install proper driver for the SATA controller.
F_AUDIO (Front Audio Connector)
Connects to the audio connector located on the front panel of the system casing
(dependent on case design). When use of the front panel audio connector is required,
please remove the 5-6 pin, 9-10pin jumper.
Please note that use of only the front panel audio connector or the rear panel audio connector
is permitted.
CD_IN (Optical Drive Audio Connector)
Connects CD-ROM or DVD-ROM audio connector.
F_USB1 (Front USB Connector)
Connects to the USB connector located on the front panel of the system casing (dependent on
case design). Note: Please make sure that each USB connection matches its designated
position. If connections are made incorrectly, the result can lead to inability to use the function
or even damage.
