• 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.
