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.
