Performance Rating

Overall performance is high enough, but the difference with the notably more expensive AX1600i is significant.

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 30°C and 32°C.


Average noise output is pretty low, given that this is a 1500 W unit.

Efficiency Rating

The graph below shows the PSU's average efficiency throughout its operating range, with an ambient temperature between 30°C and 32°C.


Average efficiency is satisfactory, but there is room for improvement.

5VSB Efficiency Rating

The graph below shows the PSU's average efficiency at 5VSB, with an ambient temperature between 30°C and 32°C.


The 5VSB rail is highly efficient.

PF Rating

The graph below shows the PSU's average PF throughout its operating range, with an ambient temperature between 30°C and 32°C.


The APFC converter needs tuning for higher readings.
