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.
