Electrical safety  
To prevent electrical shock hazard, disconnect the power cable from the electrical outlet  
before relocating the system.  
When adding or removing devices to or from the system, ensure that the power cables  
for the devices are unplugged before the signal cables are connected. If possible,  
disconnect all power cables from the existing system before you add a device.  
Before connecting or removing signal cables from the motherboard, ensure that all  
power cables are unplugged.  
Seek professional assistance before using an adapter or extension cord. These devices  
could interrupt the grounding circuit.  
Ensure that your power supply is set to the correct voltage in your area. If you are not  
sure about the voltage of the electrical outlet you are using, contact your local power  
company.  
If the power supply is broken, do not try to fix it by yourself. Contact a qualified service  
technician or your retailer.

Product introduction

1.1  
Before you proceed  
Take note of the following precautions before you install motherboard components or change  
any motherboard settings.  
Unplug the power cord from the wall socket before touching any component.  
Before handling components, use a grounded wrist strap or touch a safely grounded  
object or a metal object, such as the power supply case, to avoid damaging them due  
to static electricity.  
Hold components by the edges to avoid touching the ICs on them.  
Whenever you uninstall any component, place it on a grounded antistatic pad or in the  
bag that came with the component.  
Before you install or remove any component, ensure that the ATX power supply is  
switched off or the power cord is detached from the power supply. Failure to do so  
may cause severe damage to the motherboard, peripherals, or components.  
1.2  
Motherboard overview  
Before you install the motherboard, study the configuration of your chassis to ensure that the  
motherboard fits.  
Unplug the power cord before installing or removing the motherboard. Failure to do so can  
cause you physical injury and damage to motherboard components.  
1.2.1  
Placement direction  
When installing the motherboard, place it into the chassis in the correct orientation. The edge  
with external ports goes to the rear part of the chassis as indicated in the image.  
1.2.2  
Screw holes  
Place six screws into the holes indicated by circles to secure the motherboard to the chassis.  
Do not overtighten the screws! Doing so can damage the motherboard.
