ASUS Maximus Extreme

2-35

• 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 550 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.
