Installing the Motherboard
If the power supply connectors are not properly attached to the ATX power supply, the power supply
or add-on cards may be damaged.
One end of AC power core connects to ATX power supply, and the other end (AC plug) will plug into
the wall outlet. Be aware that when facing the wall outlet, the round hole is in the middle. The right
side slot is called ground wire slot. It has a longer slot length than the left side slot. The left side slot is
called the live wire slot. You can use an electroscope to detect its polarity or you can use a voltage
meter to measure the voltage of both slot sides. If you insert an electroscope into the live wire slot, the
electroscope will light up. Using a voltage meter, you will find that the live wire slot will register a
higher voltage.
If you reverse the polarity of AC plug, it may affect the life of computer equipment, or cause an
electric shock when you touch the computer chassis. We suggest that you plug the computer AC plug
to a three-hole wall outlet for better safety and to avoid electric shock.
(2). FAN1, FAN2, FAN3 & FAN4 header
(3). IR1: IR Header (Infrared)
Caution
Attach the connector from the CPU fan to the header
named FAN4 ond connector from the chassis fan to
the header FAN1 or FAN3 and attach the connector
from the power fan to FAN2 header.
You must attach the CPU fan to the processor, or
your processor will work abnormally or may be
damaged by overheating. To prevent the computer
case's internal temperature from getting too high,
also connect the chassis fan.
Note: Watch the pin position and the orientation
There is a specific orientation for pins 1 through 5,
attach the connector from the IR KIT or IR device to
the IR1 header (left row only). This motherboard
supports standard IR transfer rates.
Note: Watch the pin position and the orientation
