Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.

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.
•
Before you install or remove any component, ensure that the ATX power supply is
