Asus PCI/E-P54NP4 User Manual page 61

• For a fully configured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12 � Specification 2.0 (or later version)
and provides a minimum power of 400 W.
• Do not forget to connect the 4-pin/8pin EATX12� 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.
