Result Analysis and Discussion

Efficiency 115V
Load	Pin(W)	Pout(W)	Efficiency
20 %	174.1	148.51	85.30 %
50 %	425.6	368.84	86.66 %
100 %	871.6	728.74	83.61 %

The 80Plus Bronze certification requirements (82% - 85% - 82%) are surpassed especially at 20% Load. This is the case with most of todays PSU's an it mainly originates from the reason of lower losses in the AC filtering stage and the PFC at 230V AC.

Output Stability
Load	Rail	Loading(A)	Output(V)
20 %	5V	1.61	5.40
	3.3V	1.58	3.33
	12V	9.91	12.06
	5VSB	1.00	5.08
50 %	5V	2.97	5.02
	3.3V	2.90	3.34
	12V	26.57	11.98
	5VSB	1.54	5.03
100 %	5V	5.10	5.02
	3.3V	5.11	3.25
	12V	54.02	11.86
	5VSB	3.00	4.97

The stability of the output voltages and the outcome of the crossload tests (results not shown here) are not perfect but still with margin within the norms and absolutely satisfactory (especially when you consider the Topology used in this PSU).

Noise
Load
20 %	Silent
50 %	Audible
100 %	Noisy

Noise level results are decent and mostly attributed to be quiet!'s choice to use its own high-quality thermally controlled 120mm fan with rifle bearing, but we would prefer that it is much less noisy under full load.

Noise/Ripple
Voltage	Noise/Ripple Vpp
5V	0.023
12V	0.054
-12V	0.032
3.3V	0.030
+5VSB	0.036

The noise values are within the ATX norm. This is a perfect example for the quality difference between Japanese and non Japanese capacitors. The topology used in this PSU is filter friendly and Teapo capacitors are used in a high amount. However the filter performance is worse compared to high end PSUs using Japanese capacitors. Transient loads are a big issue for this topology. In modern PCs transient load changes often occur. This can end in a output Voltage not within the norm for a short moment. This again can end up in system instability.
