2-32 Chapter 2: Hardware information
•
For a fully congured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12V Specication 2.0 (or later version)
and provides a minimum power of 550 W.
• Do not forget to connect the 4-pin ATX12V power plug; otherwise, the
system will not boot.
• 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.
• Use of a PSU with a higher power output is recommended when
conguring 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.
• The ATX 12V Specication 2.0-compliant (500 W) PSU has been
tested to support the motherboard power requirement with the following
