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. If you want to know the exact method we use to calculate the performance rating of each PSU, read this article.

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 all numbers in the following graph are normalized by the rated power of each PSU.

Noise Rating

The graph below depicts the cooling fan's average noise output throughout the entire operating range of the PSU, with an ambient temperature between 28°C and 30°C.
