Efficiency Graph
230V
INFO
This graph depicts the PSU`s efficiency throughout its entire operational range. For the generation of the efficiency and noise graphs we set our loaders to auto mode through our custom-made software before trying thousands of possible load combinations
Noise Graph
230V
INFO
The PSU`s noise in its entire operational range and under 30-32 °C ambient is depicted in this graph. The X axis represents the load on the +12V rail(s) while the Y axis is the load on the minor rails

Efficiency under high ambient temperature
INFO
The PSU`s efficiency under high ambient temperatures with 115V and 230V input. For this graph the results of the 10-110% load regulation table are used
5VSB Efficiency
INFO
This graph depicts the efficiency levels of the 5VSB rail with 115V and 230V input
