1-1 Considerations Prior to Installation

Preparing Your Computer

The motherboard contains numerous delicate electronic circuits and components which can

become damaged as a result of electrostatic discharge (ESD). Thus, prior to installation, please

follow the instructions below:

1. Please turn off the computer and unplug its power cord.

2. When handling the motherboard, avoid touching any metal leads or connectors.

3. It is best to wear an electrostatic discharge (ESD) cuff when handling electronic components

(CPU, RAM).

4. Prior to installing the electronic components, please have these items on top of an antistatic pad or

within a electrostatic shielding container.

5. Please verify that the power supply is switched off before unplugging the power supply connector

from the motherboard.

1/2) ATX_12V/ATX (Power Connector)

English

With the use of the power connector, the power supply can supply enough stable power to all the

components on the motherboard. Before connecting the power connector, please make sure that all

components and devices are properly installed. Align the power connector with its proper location on

the motherboard and connect tightly.

The ATX_12V power connector mainly supplies power to the CPU. If the ATX_12V power

connector is not connected, the system will not start.

Caution!

Please use a power supply that is able to handle the system voltage requirements. It is

recommended that a power supply that can withstand high power consumption be used (300W or

greater). If a power supply is used that does not provide the required power, the result can lead to an

unstable system or a system that is unable to start.

3/4) CPU_FAN / SYS_FAN (Cooler 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 foolproof connection design.

Most coolers are designed with color-coded power connector wires. A red power connector wire

English

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.
