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.

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.

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.
