• We recommend that you use an ATX 12 V Specification 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 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.
• You must install a PSU with a higher power rating if you intend to install additional
devices.
