Chapter 1: Product introduction
• For a fully congured system, we recommend that you use a power supply unit
(PSU) that complies with ATX 12 V Specication 2.0 (or later version) and provides a
minimum power of 350 W.
• 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 conguring 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.
