1/2) ATX_12V_2X4/ATX (2x4 12V Power Connector and 2x12 Main Power Connector)

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, first make sure the

power supply is turned off and all devices are properly installed. The power connector possesses

a foolproof design. Connect the power supply cable to the power connector in the correct orientation.

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.

The power connectors are compatible with power supplies with 2x2 12V and 2x10 power

connectors. When using a power supply providing a 2x4 12V and a 2x12 power connector,

remove the protective covers from the 12V power connector and the main power connector on

the motherboard. Do not insert the power supply cables into pins under the protective covers

when using a power supply providing a 2x2 12V and a 2x10 power connector.

11) BATTERY

The battery provides power to keep the values (such as BIOS configurations, date, and time

information) in the CMOS when the computer is turned off. Replace the battery when the battery

voltage drops to a low level, or the CMOS values may not be accurate or may be lost.

You may clear the CMOS values by removing the battery:

1. Turn off your computer and unplug the power cord.

2. Gently remove the battery from the battery holder and wait for one minute.

(Or use a metal object like a screwdriver to touch the positive and

negative terminals of the battery holder, making them short for 5 seconds.)

3. Replace the battery.

4. Plug in the power cord and restart your computer.

Always turn off your computer and unplug the power cord before replacing the battery.

Replace the battery with an equivalent one. Danger of explosion if the battery is replaced

with an incorrect model.

Contact the place of purchase or local dealer if you are not able to replace the battery by

yourself or uncertain about the battery model.

When installing the battery, note the orientation of the positive side (+) and the negative

side (-) of the battery (the positive side should face up).
