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. See the table below for details.
