Power supply
40 00 €
A power supply unit (PSU) is the component that:
Converts wall outlet power (AC) into the DC power a PC uses.
Distributes power to each part of the system using the proper voltage rails (mainly 12V, 5V, and 3.3V).
Powers the motherboard, CPU, drives/SSD, fans, and—when needed—a graphics card.
Protects the system against surges, overloads, and other electrical fluctuations.
In short: a good PSU provides stable, safe power, helping prevent crashes, random shutdowns, and power-related hardware issues.
