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.

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.

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.

Chapter 1: Product Introduction

• The pin definitions in this chapter are for reference only. The pin names depend on the

location of the header/jumper/connector.

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.

• 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.

13. 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.

14. 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.

15. 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.

18. 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.

19. System Panel header

The System Panel 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.
