The 80Plus Platinum certification
requirements (90% - 92% - 89%) are surpassed especially at 20% Load. This is the case with most of todays
PSU's as it mainly originates from the reason of lower losses in the AC
filtering stage and the PFC at 230V AC.

The Voltage Regulation
of this PSU is very good. It makes use of a DC-DC topology. This means, that the
HCP-1000 Platinum is mainly a 12V PSU and then generates its 5 and 3.3V from 12V.
This is a modern approach, and since the Load is mainly on 12V it makes a lot of
sense. For almost any PSU which makes use of this topology crossload tests do
not present a problem.
