Safety information  
Electrical safety  
To prevent electric shock hazard, disconnect the power cable from the electric 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.  
Operation safety  
Before installing the motherboard and adding devices on it, carefully read all the manuals  
that came with the package.  
Before using the product, ensure that all cables are correctly connected and the power  
cables are not damaged. If you detect any damage, contact your dealer immediately.  
To avoid short circuits, keep paper clips, screws, and staples away from connectors,  
slots, sockets and circuitry.  
Avoid dust, humidity, and temperature extremes. Do not place the product in any area  
where it may become wet.  
Place the product on a stable surface.  
If you encounter technical problems with the product, contact a qualified service  
technician or your retailer.

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.
