40 00 €
A power supply unit (PSU) is the component responsible for:
Converting wall current (AC) into direct current (DC) for the PC.
Distributing power to the various components with the correct voltages (especially 12V, 5V, and 3.3V).
Powering the motherboard, CPU, drives/SSDs, fans, and, if applicable, the graphics card.
Protecting the equipment against spikes, overloads, and other electrical variations.
In summary: a good power supply ensures a stable and safe supply, avoiding restarts, shutdowns, and problems due to lack of power or poor regulation.
