Efficiency
Each PSU's efficiency is calculated by dividing the power it outputs by the power it uses to do so. Starting at 100W load, we test in 100W load increments up to an including the maximum rated wattage. While the average efficiency of all the load tests is what's considered for the scoring, the results and rankings of the individual load intervals are also displayed below.
