EFORE YOU START
Thank you for choosing our product. Before you start installing the
motherboard, please make sure you follow the instructions below:
Prepare a dry and stable working environment with
sufficient lighting.
Always disconnect the computer from power outlet
before operation.
Before you take the motherboard out from anti-static
bag, ground yourself properly by touching any safely
grounded appliance, or use grounded wrist strap to
remove the static charge.
Avoid touching the components on motherboard or the
rear side of the board unless necessary. Hold the board
on the edge, do not try to bend or flex the board.
Do not leave any unfastened small parts inside the
case after installation. Loose parts will cause short
circuits which may damage the equipment.
Keep the computer from dangerous area, such as heat
source, humid air and water.

2.1 I
NSTALLING CENTRAL PROCESSING UNIT (CPU)
Special Notice:
Remove Pin Cap before installation, and make good preservation
for future use. When the CPU is removed, cover the Pin Cap on the
empty socket to ensure pin legs won’t be damaged.
Pin-Cap
Step 1: Pull the socket locking lever out from the socket and then raise
the lever up to a 90-degree angle.

Motherboard Manual
Step 2: Look for the triangular cut edge on socket, and the golden dot on
CPU should point forwards this triangular cut edge. The CPU will
fit only in the correct orientation.
Step 2-1:
Step 2-2:
Step 3: Hold the CPU down firmly, and then lower the lever to locked
position to complete the installation.
Step 4: Put the CPU Fan and heatsink assembly on the CPU and buckle it
on the retention frame. Connect the CPU FAN power cable into
the CPU_FAN1. This completes the installation.

2.2 FANHEADERS
These fan headers support cooling-fans built in the computer. The fan
cable and connector may be different according to the fan manufacturer.
Connect the fan cable to the connector while matching the black wire to
pin#1.
