•
We recommend that you use an ATX 12V Specification 2.0-compliant power supply
unit (PSU) with a minimum of 300W power rating. This PSU type has 24-pin and 4-pin
power plugs.
•
DO NOT forget to connect the 4-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.
com/PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us for details.
