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	PF 115V
0-<20 %	185	80.47%	0.965
20-<40 %	362	85.44%	0.965
40-<60 %	361	86.22%	0.976
60-<80 %	362	85.49%	0.982
80-100 %	371	83.93%	0.986
70-100 % (High-Load)	551	84.35%	0.985
All (published average)	1641	84.72%	0.976

INFO

The average efficiency and power factor in five ranges of load. Calculated from the 1641 (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 700 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 45.8 dB(A) at 115V · loudest point 45.8 dB(A)

Efficiency 84.35% · power factor 0.985 (115V)

Load range	Noise 115V avg (loudest)	Fan off 115V
0-<20 %	26.3 (37.8)	0%
20-<40 %	34.7 (45.4)	0%
40-<60 %	43.4 (45.8)	0%
60-<80 %	45.8 (45.8)	0%
80-100 %	45.8 (45.8)	0%
70-100 % (High-Load)	45.8 (45.8)	0%
All (published average)	43.5 (45.8)	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 1641 (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 700 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%	768 RPM · 17.9 dB(A) · 30.3 °C	747 RPM · 17.4 dB(A) · 34.1 °C	-0.5 dB(A)
20%	746 RPM · 17.1 dB(A) · 30.1 °C	754 RPM · 17.4 dB(A) · 34.9 °C	+0.3 dB(A)
50%	1550 RPM · 39.8 dB(A) · 29.1 °C	1856 RPM · 46.0 dB(A) · 36.4 °C	+6.2 dB(A)
100%	1853 RPM · 46.0 dB(A) · 30.8 °C	1872 RPM · 46.3 dB(A) · 39.5 °C	+0.3 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.
