What it calculates
The “Power Supply Heat” calculator computes Losses in W from 2 parameters: load (output power) (W), psu efficiency (%).
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters Load (output power) = 500 W, PSU efficiency = 90 % the result is 55.56 W.
