Result Analysis and Discussion


Efficiency 115V

Load Pin(W) Pout(W) PF Efficiency
20 % 223.74 201.72 0.992 90.159 %
50 % 553.39 503.40 0.994 90.966 %
100 % 1'131.63 1'002.50 0.996 88.580 %


The Gold Energy certificate requirements (87%, 90%, 87%) are surpassed with huge margin.
This PSU is very simmilar to the Leadex series from Super Flower (Platinum certified). Due to cost reduction the Platinum efficiency can no longer be sustained. However the efficiency is excellent considering that this is a Gold certified PSU.
It's uncommon to see a PSU with such a high margin to the 80Plus requirement.

Output Stability

Load Rail Loading(A) Output(V)
20 % 5V 2.53 5.036
3.3V 2.53 3.316
12V 14.52 12.17
5VSB 0.53 5.065
 
50 % 5V 6.33 5.02
3.3V 7.96 3.3
12V 36.36 12.13
5VSB 1.32 5.015
 
100 % 5V 12.665 5.003
3.3V 12.662 3.275
12V 72.90 12.08
5VSB 2.698 4.945

The Voltage regulation of this PSU is very good. It makes use of a DC-DC aproach, which means, that this PSU is mainly a 12V PSU and then generates 5 and 3.3V from 12V.
This is a very modern approach, and since the load is mainly on 12V it makes a lot of sense. As most PSU, which use this Topology, the voltage regulation and the crossload test do not present a problem.

Noise/Ripple
Voltage Noise/Ripple Vpp
5V 0.007
12V 0.013
-12V 0.005
3.3V 0.014
+5VSB 0.008


Those Noise/Ripple values we got out from the Choroma test report. The noise values are extremely good. However those values are probably measured in a different way. The values should be compared to other PSU reviews with care.
