Environmental Safety Instruction
Avoid the dusty, humidity and temperature extremes. Do not place the product in
any area where it may become wet.
0 to 40 centigrade is the suitable temperature. (The figure comes from the request
of the main chipset)
Generally speaking, dramatic changes in temperature may lead to contact
malfunction and crackles due to constant thermal expansion and contraction from
the welding spots’ that connect components and PCB. Computer should go
through an adaptive phase before it boots when it is moved from a cold
environment to a warmer one to avoid condensation phenomenon. These water
drops attached on PCB or the surface of the components can bring about
phenomena as minor as computer instability resulted from corrosion and oxidation
from components and PCB or as major as short circuit that can burn the
components. Suggest starting the computer until the temperature goes up.
The increasing temperature of the capacitor may decrease the life of computer.
Using the close case may decrease the life of other device because the higher
temperature in the inner of the case.
Attention to the heat sink when you over-clocking. The higher temperature may
decrease the life of the device and burned the capacitor.
Environmental Protection Announcement
Do not dispose this electronic device into the trash while discarding. To minimize
pollution and ensure environment protection of mother earth, please recycle.

COM1 port can function as RS232/422/485 port. In normal settings COM1 functions
as RS232 port. With compatible COM cable COM1 can function as RS422 or RS 485
port.
User also needs to go to BIOS to set ‘Transmission Mode Select’for COM1 (refer to
Page-27)at first, before using specialized cable to connect different pins of this port.
2-2-2 Motherboard Internal Connectors
(1) ATXPWR (24-pin block): Main Power Connector
ATX Power Supply connector: This is a new defined 24-pins connector that usually
comes with ATX case. The ATX Power Supply allows using soft power on momentary
switch that connect from the front panel switch to 2-pins Power On jumper pole on the
motherboard. When the power switch on the back of the ATX power supply turned
on, the full power will not come into the system board until the front panel switch is
momentarily pressed. Press this switch again will turn off the power to the system
board.
** We recommend that you use an ATX 12V Specification 2.0-compliant power
supply unit (PSU) with a minimum of 350W power rating. This type has 24-pin and
4-pin power plugs.
** If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the
20-pin power plug can provide at least 15A on +12V and the power supply unit has a
minimum power rating of 350W. The system may become unstable or may not boot
up if the power is inadequate.
** If you are using a 20-pin power plug, please refer to Figure1 for power supply
connection. Power plug form power supply and power connectors from motherboard
both adopt key design to avoid mistake installation. You can insert the power plug into
the connector with ease only in the right direction. If the direction is wrong it is hard to
fit in and if you make the connection by force if is possible.

Figure1：20-pin power plug Figure 2：24-pin power plug
(2) ATX12V (8-pin block): 12V Power Connector
This is a new defined 8-pin connector that usually comes with ATX Power Supply that
supports extra 12V voltage to maintain system power consumption. Without this
connector might cause system unstable because the power supply can not provide
sufficient current for system.

M2M M.2 M-Key slot supports compatible type 2242/2260/2280/22110 SATA or PCIE
x4 SSD module.
M2M Slot Installation Guide:
1. Prepare compatible M.2 SATA or M.2 SSD card. Deferent type of cards has
different length. Find corresponding nut location for further installation.

2. Remove the screw post and nut fixed at
location MH4 by default (Skip step 2 & 3
and go straight to Step 4 if you are going
to use the default nut).
3. Lock the screw post into the location
corresponding to the length of the
module.
4. Align and insert corresponding M.2
module, as the photo shows.
5. Tighten up the screw to secure the
module into the M.2 connector. Mare
sure not overtighten the screw to avoid
possible damage to the module.
(6) Dual Channel Memory Installation:
Notice!
For dual channel installation, you need to install the same brand, speed, size and
type memory module.
It is unable to activate dual channel feature if you install one or three memory
modules, or you install DIMM1 & DIMM4 / DIMM2 & DIMM3. Slot order can be
from left-to-right or right-to-left, and it must be installed in pairs.
If you install memory modules in wrong direction, it will damage the motherboard
and memory module.
