Performance, Performance Per Dollar And Noise Ratings
Performance Rating
The following graph shows the total performance rating of the PSU, comparing it with other units we have tested in the past. To be more specific, the tested unit is shown as 100 percent, and every other unit's performance is shown relative to it.
Only the significantly more expensive Seasonic SS-520FL manages to surpass the performance of the small- capacity Platinum Leadex platform. Seasonic is still in the game, and if the company decides to offer a high-end product in this category with a normal, non-passive operation, then Super Flower will have a worthy opponent to face.
Performance Per Dollar
The following chart may be the most interesting to many of you because it depicts the unit'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 the specific unit wasn't available in the United States, we searched for it in popular European Union shops, converting the listed price to U.S. dollars (without the VAT). Note that all of the numbers in the following graph are normalized by the rated power of each PSU.
Although performance is very high, the same applies to the PSU's asking price, hence the performance-per- dollar ratio isn't very high.
Noise Rating
The graph below depicts the cooling fan's average noise over the PSU's entire operating range, with an ambient temperature between 28 and 30 C (82 to 86 F).
This is the most silent PSU (passive ones excluded) that we have ever tested. Super Flower has a clear winner with this model, which allows them to easily conquer the corresponding market segment since the alternative offerings are limited and, as you can see from the table above, they put out much more noise.
