1-20 Chapter 1: Product introduction
Chapter 1
• For a fully configured system, we recommend that you use a power supply unit
(PSU) that complies with ATX 12V Specification 2.3 (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 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 want to use two high-end PCI Express x16 cards, use a PSU with 1000W power
or above to ensure the system stability.
• 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.
