The 80Plus Gold certification
requirements (87% - 90% - 87%) are surpassed especially at 20% Load. The full Load
efficiency is a bit higher at 230V AC. 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. The 230V AC 100% Load efficiency is 90.50%.

The Voltage Regulation of
this PSU is good. It makes use of a DC-DC topology. This means, that the
SX600-G 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.

If we listen closer with the power supply, we can say that it's silent at 20 percent load. At 50% load the unit is well audible and the same goes for 100% load.
