1.7.4 ATX power connectors (ATX24P_1& ATX12V)
The connector is 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.
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.
