7. ATX power connectors (24-pin EATXPWR; 8-pin EATX12V)
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 12 V Specification 2.0 (or later version) and provides a minimum
power of 450 W.
• Do not forget to connect the 8-pin EATX12 V power plug; otherwise, the system will not
boot.
• We recommend that you use a PSU with higher power output 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.
