Chapter 2 Installation
is is a Deep Micro-ATX form factor (10.4” x 10.5”, 265 x 26.7 cm) motherboard. Before
you install the motherboard, study the conguration of your chassis to ensure that the
motherboard ts into it.
Make sure to unplug the power cord before installing or removing the motherboard. Failure
to do so may cause physical injuries to you and damages to motherboard components.

please do not over-tighten the screws! Doing so may damage the motherboard.
Before you install or remove any component, ensure that the power is switched o or the
power cord is detached from the power supply. Failure to do so may cause severe damage to
the motherboard, peripherals, and/or components.
