Performance Per Dollar

The following chart may be the most interesting to many of you because it depicts the MasterWatt Maker 1200's performance-per-dollar score. We looked up the current price of each PSU on popular online shops and used those prices and all relative performance numbers to calculate the index. If a specific unit wasn't available in the United States, we searched for it in popular European Union shops, converting the listed price to USD (without VAT). Note that all of the numbers in the following graph are normalized by the rated power of each PSU.

Efficiency in the 10%-100% range is high. However, under very light loads it's very low. This affects the MasterWatt Maker 1200's overall efficiency score, of course. Enhance tried to pull a little trick by tuning the PSU to only comply with the 80 PLUS Titanium certification's requirements; however our methodology is much stricter.
