How is power supply efficiency calculated
Web19 sep. 2024 · Calculating the total efficiency requires using airflow, pressure, and input power. This factor disregards the efficiency of the drive (belt drive) and motor. You can calculate both the static and total efficiency of a fan from its performance data as follows: Static\ Efficiency=\frac {CFM\times p} {6343\times BHP} WebThere is some loss during this conversion. How much depends on the quality of your PSU and on how much power you draw from it. Almost any PSU is very inefficient when you draw less then 20% of max rated power from it. Almost any PSU has less than peak efficiency when you draw close to the max rated power from it.
