Output-based and input-based power consumption
Power consumption is defined as either an “output power-based value” based on the power supply unit's output side, or an “input power-based value” based on the power supply unit's input side. Numbers such as “3000W” for AC power supplies or “2500W” for DC power supplies represent output power-based values. Therefore, when estimating the number of power supplies required for a system, output power-based values must be used.

On the input side of the power supply, power conversion efficiency means more power is required than the output power base indicates. When designing input power supply capacity, use the input power base figures. The figures in the notes are values based on input power, calculated using the power conversion efficiency (92%).
