7. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)
These connectors are for an ATX power supply. The plugs from
the power supply are designed to fit these connectors in only one
orientation. Find the proper orientation and push down firmly until the
connectors completely fit.
• It is recommended that you use an ATX 12 V Specification
2.0-compliant power supply unit (PSU) with a minimum of 350 W
power rating. This PSU type has 24-pin and 4-pin power plugs.
• Do not forget to connect the 4-pin ATX +12 V power plug;
otherwise, the system will not boot up.
• 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.
• You must install a PSU with a higher power rating if you intend to
install additional devices.
