CPU Fan Connector
(4-pin CPU_FAN1)
(see p.2 No. 4)
Though this motherboard provides 4-Pin CPU fan (Quiet Fan) support, the 3-Pin
CPU fan still can work successfully even without the fan speed control function.
If you plan to connect the 3-Pin CPU fan to the CPU fan connector on this
motherboard, please connect it to Pin 1-3.
ATX Power Connector
(24-pin ATXPWR1)
(see p.2 No. 3)
Though this motherboard provides 24-pin ATX power connector,
it can still work if you adopt a traditional 20-pin ATX power supply.
To use the 20-pin ATX power supply, please plug your power
supply along with Pin 1 and Pin 13.
ATX 12V Power Connector

20-Pin ATX Power Supply Installation
Please note that it is necessary
to connect a power supply with
ATX 12V plug to this connector.
Failing to do so will cause power
up failure.
This COM1 header
supports a serial port module.
Besides one default IEEE 1394
port on the I/O panel, there is one
IEEE 1394 header
(FRONT_1394) on this
motherboard. This IEEE 1394
header can support one IEEE
1394 port.
