•
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 ATX12V 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 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.
•
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.
