We recommend that you use an EATX 12V Specification
2.0-compliant power supply unit (PSU) with a minimum of 300W
power rating. This PSU type has 24-pin and 8-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.com/
PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us for
details.
