Safety information

Electrical safety

• To prevent electrical shock hazard, disconnect the power cable from the electrical outlet

before relocating the system.

• When adding or removing devices to or from the system, ensure that the power cables

for the devices are unplugged before the signal cables are connected. If possible,

disconnect all power cables from the existing system before you add a device.

• Before connecting or removing signal cables from the motherboard, ensure that all power

cables are unplugged.

• Seek professional assistance before using an adapter or extension cord. These devices

could interrupt the grounding circuit.

• Ensure that your power supply is set to the correct voltage in your area. If you are not

sure about the voltage of the electrical outlet you are using, contact your local power

company.

• If the power supply is broken, do not try to x it by yourself. Contact a qualied service

technician or your retailer.

Operation safety

• Before installing the motherboard and adding components, carefully read all the manuals

that came with the package.

• Before using the product, ensure all cables are correctly connected and the power cables

are not damaged. If you detect any damage, contact your dealer immediately.

• To avoid short circuits, keep paper clips, screws, and staples away from connectors,

slots, sockets and circuitry.

• Avoid dust, humidity, and temperature extremes. Do not place the product in any area

where it may become wet.

• Place the product on a stable surface.

• If you encounter technical problems with the product, contact a qualied service

technician or your retailer.

• Your motherboard should only be used in environments with ambient temperatures

between 0°C and 40°C.

Product Introduction

1.1 Before you proceed

Take note of the following precautions before you install motherboard components or change

any motherboard settings.

• Unplug the power cord from the wall socket before touching any component.

• Before handling components, use a grounded wrist strap or touch a safely grounded

object or a metal object, such as the power supply case, to avoid damaging them due

to static electricity.

• Hold components by the edges to avoid touching the ICs on them.

• Whenever you uninstall any component, place it on a grounded antistatic pad or in the

bag that came with the component.

• Before you install or remove any component, ensure that the ATX power supply is

switched off or the power cord is detached from the power supply. Failure to do so

may cause severe damage to the motherboard, peripherals, or components.

• The pin denitions in this chapter are for reference only. The pin names depend on the

location of the header/jumper/connector.

transfer speeds of up to 480 Mb/s.

DO NOT connect a 1394 cable to the USB connectors.

Doing so will damage the motherboard!

The USB 2.0 module is purchased separately.

10. Addressable Gen 2 headers

The Addressable Gen 2 headers allow you to connect individually addressable

RGB WS2812B LED strips or WS2812B based LED strips.

The Addressable Gen 2 headers support WS2812B addressable RGB LED strips (5V/Data/

Ground), with a maximum power rating of 3A (5V), and the addressable headers on this

board can handle a combined maximum of 500 LEDs.

Before you install or remove any component, ensure that the power supply is switched off

or the power cord is detached from the power supply. Failure to do so may cause severe

damage to the motherboard, peripherals, or components.

• Actual lighting and color will vary with LED strip.

• If your LED strip does not light up, check if the addressable RGB LED strip is

connected in the correct orientation, and the 5V connector is aligned with the 5V

header on the motherboard.

• The addressable RGB LED strip will only light up when the system is powered on.

• The addressable RGB LED strip is purchased separately.

11. Aura RGB headers

The Aura RGB headers allow you to connect RGB LED strips.

The Aura RGB headers support 5050 RGB multi-color LED strips (12V/G/R/B), with a

maximum power rating of 3A (12V), and no longer than 3m.

Before you install or remove any component, ensure that the ATX power supply is switched

off or the power cord is detached from the power supply. Failure to do so may cause severe

damage to the motherboard, peripherals, or components.

• Actual lighting and color will vary with LED strip.

• If your LED strip does not light up, check if the RGB LED extension cable and the

RGB LED strip are connected in the correct orientation, and the 12V connector is

aligned with the 12V header on the motherboard.

• The LED strip will only light up when the system is powered on.

• The LED strip is purchased separately.

12. Clear CMOS header

The Clear CMOS header allows you to clear the Real Time Clock (RTC) RAM in

the CMOS, which contains the date, time, system passwords, and system setup

parameters.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Short-circuit pin 1-2 with a metal object or jumper cap for about 5-10 seconds.

3. Plug the power cord and turn ON the computer.

4. Hold down the <Del> key during the boot process and enter BIOS setup to

re-enter data.

DO NOT short-circuit the pins except when clearing the RTC RAM. Short-circuiting or

placing a jumper cap will cause system boot failure!

If the steps above do not help, remove the onboard button cell battery and short the two

pins again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the button

cell battery.

13. COM Port header

The COM (Serial) Port header allows you to connect a COM port module.

Connect the COM port module cable to this header, then install the module to a

slot opening on the system chassis.

The COM port module is purchased separately.

14. Front Panel Audio header

The Front Panel Audio header is for a chassis-mounted front panel audio

I/O module that supports HD Audio. Connect one end of the front panel

audio I/O module cable to this header.

We recommend that you connect a high-denition front panel audio

module to this header to avail of the motherboard’s high-denition

audio capability.

15. S/PDIF Out header

The S/PDIF Out header allows you to connect the Sony/Philips Digital Interface

(S/PDIF) Out module.

The S/PDIF module is purchased separately.

16. SPI TPM header

This header supports a Trusted Platform Module (TPM)

system with a Serial Peripheral Interface (SPI), allowing you

to securely store keys, digital certicates, passwords, and

data. A TPM system also helps enhance network security,

protects digital identities, and ensures platform integrity.

The TPM module is purchased separately.

17. System Panel header

This header supports several chassis-mounted functions.

• System Power LED header (PLED)

The 2-pin and/or 3-1 pin headers allow you to connect the

System Power LED. The System Power LED lights up when

the system is connected to a power source, or when you

turn on the system power, and blinks when the system is in

sleep mode.

• Storage Device Activity LED header (HDD_LED)

The 2-pin header allows you to connect the Storage Device

Activity LED. The Storage Device Activity LED lights up or blinks when data is read

from or written to the storage device or storage device add-on card.

• System Warning Speaker header (SPEAKER)

The 4-pin header allows you to connect the chassis-mounted system warning speaker.

The speaker allows you to hear system beeps and warnings.

• Power Button/Soft-off Button header (PWRSW)

The 2-pin header allows you to connect the system power button. Press the power

button to power up the system, or put the system into sleep or soft-off mode

(depending on the operating system settings).

• Reset button header (RESET)

The 2-pin header allows you to connect the chassis-mounted reset button. Press the

reset button to reboot the system.

• Chassis intrusion header (CHASSIS)

The 2-pin header allows you to connect the chassis-mounted intrusion detection

sensor or switch. The chassis intrusion sensor or switch sends a high-level signal

to the header when a chassis component is removed or replaced, the signal is then

generated as a chassis intrusion event.
