• 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.
