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

Efficiency and power factor by load range

Load range	Points	Efficiency 115V
0-<20 %	218	86.14%
20-<40 %	342	91.20%
40-<60 %	342	91.71%
60-<80 %	344	90.68%
80-100 %	352	89.52%
70-100 % (High-Load)	522	89.78%
All (published average)	1598	90.14%

INFO

The average efficiency and power factor in five ranges of load. Calculated from the 1598 (115V) load combinations of the certification sweep, the same data that ETA and LAMBDA use (test 0 excluded). Load is the total DC output as a share of the rated 750 W. These are plain averages of the valid readings, as for the ETA rating, so the ranges combined give back the published averages.

Informational. Not part of the ETA or LAMBDA rating.

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 by load range

High-Load Index (70-100 % load)

Noise 33.0 dB(A) at 115V · loudest point 33.7 dB(A)

Efficiency 89.78% (115V)

Load range	Noise 115V avg (loudest)	Fan off 115V
0-<20 %	16.9 (16.9)	0%
20-<40 %	16.9 (16.9)	0%
40-<60 %	17.9 (27.9)	0%
60-<80 %	29.5 (33.7)	0%
80-100 %	33.6 (33.7)	0%
70-100 % (High-Load)	33.0 (33.7)	0%
All (published average)	28.6 (33.7)	0%

INFO

The average noise in five ranges of load, the share of points with the fan stopped (semi-passive operation), and the High-Load Index: the same figures for all points at 70 % of the rated output and above. Calculated from the 1598 (115V) load combinations of the certification sweep, the same data that ETA and LAMBDA use (test 0 excluded). Load is the total DC output as a share of the rated 750 W. Noise is averaged on the energy scale, as for LAMBDA, so the ranges combined give back the published average noise. Each load combination is held for about five seconds; the stabilized readings at fixed loads are under "Noise under high ambient temperature".

Informational. Not part of the ETA or LAMBDA rating.

Noise under high ambient temperature (indicative)

115V

Load	Normal ambient fan · noise · intake	High ambient fan · noise · intake	Noise change
10%	845 RPM · 16.7 dB(A) · 34.3 °C	845 RPM · 16.7 dB(A) · 34.3 °C	+0.0 dB(A)
20%	849 RPM · 16.9 dB(A) · 34.6 °C	849 RPM · 16.9 dB(A) · 34.6 °C	+0.0 dB(A)
50%	886 RPM · 17.8 dB(A) · 36.0 °C	886 RPM · 17.8 dB(A) · 36.0 °C	+0.0 dB(A)
100%	1514 RPM · 34.0 dB(A) · 39.3 °C	1514 RPM · 34.0 dB(A) · 39.3 °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: the fan is stopped or too quiet to measure (the fan speed column says which); with the fan stopped, the intake sensor can read higher than the chamber air.

Informational. Not part of the ETA or LAMBDA rating.
