We recommend that you use an ATX 12V Specification 2.0-compliant power supply
unit (PSU) with a minimum of 300W 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, ensure that the 20-pin
power plug can provide at least 15 A on +12V and that the PSU has a minimum power
rating of 300W. The system may become unstable or may not boot up if the power is
inadequate.
DO NOT forget to connect the 4-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 are uncertain about the minimum power supply requirement for your system,
refer to the Recommended Power Supply Wattage Calculator at http://support.asus.
