Safety Information
∙The components included in this package are prone to damage from electrostatic
discharge (ESD). Please adhere to the following instructions to ensure successful
computer assembly.
∙Ensure that all components are securely connected. Loose connections may cause
the computer to not recognize a component or fail to start.
∙Hold the motherboard by the edges to avoid touching sensitive components.
∙It is recommended to wear an electrostatic discharge (ESD) wrist strap when
handling the motherboard to prevent electrostatic damage. If an ESD wrist strap
is not available, discharge yourself of static electricity by touching another metal
object before handling the motherboard.
∙Store the motherboard in an electrostatic shielding container or on an anti-static
pad whenever the motherboard is not installed.
∙Before turning on the computer, ensure that there are no loose screws or metal
components on the motherboard or anywhere within the computer case.
∙Do not boot the computer before installation is completed. This could cause
permanent damage to the components as well as injury to the user.
∙If you need help during any installation step, please consult a certified computer
technician.
∙Always turn off the power supply and unplug the power cord from the power outlet
before installing or removing any computer component.
∙Keep this user guide for future reference.
∙Keep this motherboard away from humidity.
∙Make sure that your electrical outlet provides the same voltage as is indicated on
the PSU, before connecting the PSU to the electrical outlet.
∙Place the power cord such a way that people can not step on it. Do not place
anything over the power cord.
∙All cautions and warnings on the motherboard should be noted.
∙If any of the following situations arises, get the motherboard checked by service
