Chapter 1
• For a fully congured system, we recommend that you use a power supply unit
(PSU) that complies with ATX 12V Specication 2.0 (or later version) and provides a
minimum power of 350 W.
• DO NOT forget to connect the 4-pin/8-pin EATX12V power plug. Otherwise, the
system will not boot.
• We recommend that you use a PSU with a higher power output when conguring 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.
