Analyse des résultats et discussion

Rendement
Charge	Pin(W)	Pout(W)	Rendement
10 %	114.00 W	101.18 W	88.76 %
20 %	219.20 W	202.11 W	92.20 %
50 %	543.80 W	504.03 W	92.69 %
100 %	1114.20 W	1000.05 W	89.76 %

The 80Plus Platinum certification requirements (90% - 92% - 89%) 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 90.68%.

Stabilité des tensions de sortie

10 %	3.3 V	1.5 A	3.3 V
	5 V	1.5 A	5.0 V
	12 V	7.1 A	12.1 V

20 %	3.3 V	3.1 A	3.3 V
	5 V	3.1 A	5.0 V
	12 V	14.2 A	12.1 V

50 %	3.3 V	7.7 A	3.3 V
	5 V	7.6 A	5.0 V
	12 V	35.6 A	12.1 V

100 %	3.3 V	15.3 A	3.3 V
	5 V	15.2 A	5.0 V
	12 V	71.1 A	12 V

The Voltage Regulation of this PSU is very good. It makes use of a DC-DC topology. This means, that the HX1000 2017 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 don't here anything at 20 percent load. The HX1000 2017 is a semi passive power supply and the fan kicks in, when 35 percent load is reached. It keeps spinning until the load goes below 25 percent. This ensures adequate internal temperatures under all circumstances. When demanding 50 percent load from this unit, the noise level can be described as silent and when there is 100 percent load, the unit is well audible.
