Efficiency Graph

115V

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

115V

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

Noise under high ambient temperature (indicative)

20%	729 RPM · 16.5 dB(A) · 30.5 °C	739 RPM · 17.1 dB(A) · 34.9 °C	+0.6 dB(A)
50%	1661 RPM · 41.7 dB(A) · 30.8 °C	1828 RPM · 45.6 dB(A) · 36.1 °C	+3.9 dB(A)
100%	1832 RPM · 45.6 dB(A) · 30.1 °C	1839 RPM · 45.6 dB(A) · 39.7 °C	+0.0 dB(A)

INFO

Fan speed, noise and the measured intake temperature at 10, 20, 50 and 100 % load, from the two load regulation tests: at normal ambient (about 30-32 °C) and at high ambient (about 40-47 °C). These are stabilized readings at fixed loads, not averages over the certification sweep, so they are indicative of how the fan behaves when it is hot. "<6.0" is the floor of our sound meter, with the fan stopped; with the fan stopped, the intake sensor can read higher than the chamber air.

Informational. Not part of the ETA or LAMBDA rating.
