Efficiency Graph

Description

This graph depicts the PSU's efficiency throughout its entire operational range. For the generation of the efficiency and noise graphs, loaders were set to auto mode through custom-made software before trying thousands of possible load combinations.

Details

Noise Graph

Description

This graph depicts the PSU's noise in its entire operational range and under 30-32°C ambient. The X-axis represents the load on the +12V rail(s) while the Y-axis represents the load on the minor rails.
