ATX power connectors

(24-pin EATXPWR and 4-pin ATX12V)
These connectors are for ATX power supply plugs. The power supply plugs
are designed to fit these connectors in only one orientation. Find the proper
orientation and push down firmly until the connectors completely fit.
• For a fully configured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12V Specification 2.0 (or later version)
and provides a minimum power of 400W.
• Do not forget to connect the 4-pin ATX 12V 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 requirement for your system,
refer to the Recommended Power Supply Wattage Calculator at
http://support.asus.com/PowerSupplyCalculator/PSCalculator.

• The ATX 12 V Specification 2.0-compliant PSU passed the motherboard
power requirement test with the following configuration:
