Performance Rating

The following graph shows the total performance rating of the PSU in comparison with other units we have tested before. To be more specific the tested unit is shown as 100% and all other units' performance are relative to it. If you want take a look at the exact method we use to calculate the performance rating of each PSU then read this article.

Performance per Dollar

For most of you probably the following graph will be the most interesting, since it shows how much it will set you back the performance of the PSU you want to buy. We looked up the current USD price of each PSU on the popular online shop Newegg and used it along with the relative performance numbers to calculate the Performance per Dollar Index. In case Newegg doesn't stock a specific unit then we search for it at other popular online shops (Tigerdirect, Amazon) and finally if the unit is not sold in the U.S. we search in popular EU shops (e.g. Caseking) and we convert its price to dollars. Note in the following graph all numbers are normalized by the rated power of each PSU. Finally we used the price of the basic Thunderbolt 1200W in the following graph (although we kept the original model number at least in this graph) for two reasons, we couldn't find a price for the Plus model and even if we could it wouldn't be a fair comparison since the Plus models feature the iPower meter device which adds a few bucks in the cost along with some functionality.
