6. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)
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 EATX 12 V Specification 2.0 (or later version) and provides a
minimum power of 400 W.
• Do not forget to connect the 4-pin ATX12V power plug. Otherwise, the system will not
boot.
• We recommended that you use a PSU with a 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.
7. Speaker connector (4-pin SPEAKER)
This 4-pin connector is for the chassis-mounted system warning speaker. The speaker
allows you to hear system beeps and warnings.
