11. ATX power connectors (24-pin ATX-PWRGD, 4-pin ATX12V)
These connectors are for an ATX power supply. The plugs from the power
supply 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 12 V Specification 2.0 (or later version)
and provides a minimum power of 400 W.
• Do not forget to connect the 4-pin EATX12V 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.
