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 t these connectors in only one orientation. Find the proper
orientation and push down rmly until the connectors completely t.
• For a fully congured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12 V Specication 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 sufcient power supply
when you install multiple graphics cards.
• Use of a PSU with a higher power output is recommended when
conguring 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 certied 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
