9. ATX power connectors. (8-pin EATX12V, 4-pin EATX12V_1, 24-pin EATXPWR, 4-pin EZ_PLUG) 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 600 W. • Do not forget to connect the 8-pin EATX12V power plug; otherwise, the system will not boot. • Connect the 4-pin EZ_PLUG power plugs to ensure sufficient power supply when you install multiple graphics cards. • 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. Refer to the Appendix for the certified 500W power supply or above. • 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. 2-26 Chapter 2: Hardware information
