Use of an ATX 12 V Specification 2.0-compliant power supply unit (PSU)
that provides a minimum power of 350 W is recommended for a fully-
configured system.
Do not forget to connect the 4-pin ATX +12 V power plug; otherwise, the
system will not boot up.
Use of a power supply unit (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 PSU can provide at least the minimum power required
by your system.
