Before we dive into the calculation process, it's essential to understand what PSU wattage represents. The wattage of a PSU, measured in watts (W), indicates its ability to supply power to your system's components. A higher wattage PSU can provide more power to your system, but it's not always necessary to choose the highest wattage PSU available.
