Performance Rating

The following graph shows the total performance rating of the PSU in comparison to other units we have tested before. To be more specific, the tested unit is shown as 100% and every other unit's performance is relative to it. Take a look at this article if you want to read up on the exact method we use to calculate the performance rating of each PSU.

Performance per Dollar

For most of you, the following graph is the most interesting because it shows the performance per dollar of the PSU you may consider buying. We looked up the current USD price of each PSU on the popular online shop Newegg and used it and all relative performance numbers to calculate the performance-per-dollar index. If Newegg didn't have a specific unit in stock, we searched for it at other popular online shops (e.g., TigerDirect, Amazon) and, finally, if the unit was not sold in the USA, we searched for the product at popular EU shops (e.g., Caseking) and then, if found, converted its price to USD (w/o VAT). Note that, in the following graph, all numbers are normalized by the rated power of each PSU.

Noise Rating

The graph below compares each PSU's average fan-noise measurement throughout its entire operating range. The ambient temperature was between 28°C and 30°C.
