10. 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. • Ensure to remove the cap on the EATX12V connector before connecting an 8-pin EPS +12V power plug. • Use only an 8-pin EPS +12V power plug for the EATX12V connector. • 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 8-pin EATX12 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. 2-38 Chapter 2: Hardware information

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.

Ensure to remove the cap on the EATX12V connector before connecting an
8-pin EPS +12V power plug.
•
Use only an 8-pin EPS +12V power plug for the EATX12V connector.
•
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 8-pin EATX12 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
