Chapter 1: Product introduction
•
We recommend that you use an ATX 12V Specification 2.0-compliant or later version
power supply unit (PSU) with a minimum of 350W power rating. This PSU type has
24-pin and 4-pin power plugs.
•
DO NOT forget to connect the 4-pin / 8-pin ATX +12V power plug. Otherwise, the
system will not boot up.
•
We recommend that you use a PSU with higher power output when configuring a
system with more power-consuming devices or when you intend to install additional
devices. The system may become unstable or may not boot up if the power is
inadequate.
•
If you are uncertain about the minimum power supply requirement for your system,
refer to the Recommended Power Supply Wattage Calculator at http://support.asus.

for details.
