3. ATX power connectors (24-pin EATXPWR, 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 600 W.
• Do not forget to connect the 4-pin ATX +12 V 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.aspx?SLanguage=en-us for details.
