•

We recommend that you use an ATX 12 V Specication 2.0-compliant power supply

unit (PSU) with a minimum of 300 W power rating. This PSU type has 24-pin and

4-pin power plugs.

•

If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the 20-

pin power plug can provide at least 15 A on +12 V and that the PSU has a minimum

power rating of 300 W. The system may become unstable or may not boot up if the

power is inadequate.

•

Do not forget to connect the 4-pin ATX +12 V power plug; otherwise, the system will

not boot up.

• We recommend that you use a PSU with higher power output when conguring 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.

•

You must install a PSU with a higher power rating if you intend to install additional

devices.
