8 . ATX power connectors (24-pin EATXPWR, 4-pin ATX12V1, 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. • 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. • Make sure that your power supply unit (PSU) can provide at least the minimum power required by your system. See the table below for details.
