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.

1-2 Layout Diagram
Rear IO Diagram
*Note:Many PCs now include XHCI USB controllers which allow for the support of USB 3.0(or higher
version) and higher USB speeds. This inclusion of XHCI controllers has lessened the need for EHCI
USB controllers within platforms. However, legacy operating systems (OS) may not natively recognize
XHCI controllers. You might need to pre-install XHCI driver while desiring to install a non-XHCI OS
(ex.Windows* 7) on Intel platforms which do not include EHCI controllers. Please contact your
representative for more details.

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.

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.
