•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 EATX12V power plug; otherwise, the system will not boot.

•If you install only one CPU on the CPU0 socket, you can connect only the EATXPWR and EATX12V power connectors to boot the system.

•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 want to use two high-end PCI Express x16 cards, use a PSU with 600W 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.
