The following graph shows the NJ450-SXL’s total performance rating, comparing it to other units we have tested. 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 Corsair SF Platinum units manage to surpass the overall performance of the NJ450-SXL, however those units use active cooling (but on the other hand have smaller dimensions since they are SFX units).
Performance Per Dollar/Pound
The following chart may be the most interesting to many of you because it depicts the product’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. Note that all of the numbers in the following graphs are normalized by the rated power of each unit.
This is a very expensive PSU, especially for its capacity, so normally its performance per buck/pound ratio is crippled despite of the high performance.
The graph below depicts the cooling fan’s average noise over the PSU’s operating range, with an ambient temperature between 30°C and 32°C (86°F to 89.6°F).
The following graph shows the PSU’s average efficiency throughout its operating range, with an ambient temperature close to 30°C.
The average efficiency derived by thousands of possible load combinations always speaks the truth and in this case it clearly shows that the NJ450-SXL is the most efficient 450W supply that money can buy today.
