Asus P5K/EPU Computer Hardware User Manual


 
ASUS P5K/EPU
2-31
For a fully congured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12 V Specication 2.0 (or later version)
and provides a minimum power of 400 W.
Do not forget to connect the 4-pin ATX12V power plug; otherwise, the
system will not boot.
Use of a PSU with a higher power output is recommended 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 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.
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.
