The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected,
the computer will not start.
To meet expansion requirements, it is recommended that a power supply that can withstand high
power consumption be used (500W or greater). If a power supply is used that does not provide the
required power, the result can lead to an unstable or unbootable system.

All fan headers on this motherboard are 4-pin. Most fan headers possess a foolproof insertion design.
When connecting a fan cable, be sure to connect it in the correct orientation (the black connector wire is
the ground wire). The speed control function requires the use of a fan with fan speed control design. For
optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.
•Be sure to connect fan cables to the fan headers to prevent your CPU and system from
overheating. Overheating may result in damage to the CPU or the system may hang.

The front panel design may differ by chassis. A front panel module mainly consists of power switch,
reset switch, power LED, hard drive activity LED, speaker and etc. When connecting your chassis
front panel module to this header, make sure the wire assignments and the pin assignments are
matched correctly.
14) F_PANEL(FrontPanelHeader)
Connect the power switch, reset switch, speaker, chassis intrusion switch/sensor and system status indicator
on the chassis to this header according to the pin assignments below. Note the positive and negative pins
before connecting the cables.
System Status LED
S0 On
S3/S4/S5 Off
•PW(PowerSwitch,Red):
Connects to the power switch on the chassis front panel. You may
congurethewaytoturnoffyoursystemusingthepowerswitch(refer
toChapter2,"BIOSSetup,""Power,"formoreinformation).
•SPEAK(Speaker, Orange):
Connects to the speaker on the chassis front panel. The system reports
system startup status by issuing a beep code. One single short beep
will be heard if no problem is detected at system startup.
•PLED/PWR_LED(Power LED, Yellow/Purple):
Connects to the power status indicator
on the chassis front panel. The LED is on
when the system is operating. The LED is
off when the system is in S3/S4 sleep state
or powered off (S5).
•HD (Hard Drive Activity LED, Blue):
Connects to the hard drive activity LED on the chassis front panel. The LED is on when the hard drive
is reading or writing data.
•RES(ResetSwitch,Green):
Connects to the reset switch on the chassis front panel. Press the reset switch to restart the computer
ifthecomputerfreezesandfailstoperformanormalrestart.
•CI (Chassis Intrusion Header, Gray):
Connects to the chassis intrusion switch/sensor on the chassis that can detect if the chassis cover has
been removed. This function requires a chassis with a chassis intrusion switch/sensor.
•NC(Orange): No connection.
15) F_AUDIO(FrontPanelAudioHeader)
 ThefrontpanelaudioheadersupportsHighDenitionaudio(HD).Youmayconnectyourchassisfront
panel audio module to this header. Make sure the wire assignments of the module connector match the
pin assignments of the motherboard header. Incorrect connection between the module connector and the
motherboard header will make the device unable to work or even damage it.
Some chassis provide a front panel audio module that has separated connectors on each wire
instead of a single plug. For information about connecting the front panel audio module that has
different wire assignments, please contact the chassis manufacturer.

This header supports digital S/PDIF Out and connects a S/PDIF digital audio cable (provided by expansion
cards) for digital audio output from your motherboard to certain expansion cards like graphics cards and
sound cards. For example, some graphics cards may require you to use a S/PDIF digital audio cable for
digital audio output from your motherboard to your graphics card if you wish to connect an HDMI display
to the graphics card and have digital audio output from the HDMI display at the same time. For information
about connecting the S/PDIF digital audio cable, carefully read the manual for your expansion card.
