5. ATX power connectors (20-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.
y Do not forget to connect the 4-pin ATX +12 V power plug;
otherwise, the system will not boot.
y 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.
y 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.
