For a fully configured system, we recommend that you use a power supply unit
(PSU) that complies with ATX 12 V Specification 2.0 (or later version) and provides a
minimum power of 600 W.
Do not forget to connect the 8-pin ATX +12 V power plug; otherwise, the system will
not boot.
Use of a PSU with a higher power output is recommended when configuring a system
with more power-consuming 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.
