• 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 400 W. • Do not forget to connect the 4-pin/8pin EATX12V 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. • If you want to use two high-end PCI Express x16 cards, use a PSU with 500W to 600W power or above to ensure the system stability. 9.
