EATX12V
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 350 W.
DO NOT forget to connect the 4-pin/8-pin ATX +12V power plug. Otherwise, the
system will not boot up.
We recommend that you use a PSU with higher power output when configuring a
system with more power-consuming devices or when you intend to install additional
devices. The system may become unstable or may not boot up if the power is
inadequate.
If you want to use two or more 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.
