Rendement

Charge Pin(W) Pout(W) Rendement
10 % 83.44 76.52 91.71 %
20 % 163.53 153.48 93.85 %
50 % 407.60 385.56 94.59 %
100 % 834.00 774.67 92.89 %


The 80Plus Titanium certification requirements (90% - 92% - 94% - 90%) 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%.

The Voltage Regulation of this PSU is very good. It makes use of a DC-DC topology. This means, that the Seasonic Prime Titantium 750W 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.

10 % Inaudible

50 % Inaudible
100 % silencieux


If we listen closer with the power supply, there is no noise until 50%. The Seasonic Prime Titantium 750W is a semi passive power supply and the fan kicks in, when 50 percent load is being surpassed. Even at 100% load the unit can still be described as silent.
