The efficiency of the power supply is very good with a partial load. It achieves a level of 88% at 50% load and almost 86% at 20% load. The power supply also does well in the 35 watt test, where it still reaches 74.4%. Under full load, the power supply reaches 85.6% which is still a good level of efficiency.
The power supply doesn’t achieve particularly special results in standby mode. A power consumption of 4.41 watts results in a level of efficiency of just 56.6%. Without load, consumption is pretty low at 0.61 watts.
Incidentally, the difference in energy consumption with the fan on or off is just 0.5 watts.

Fortron/FSP’s power supply with partially passive operation was a good idea. The implementation is not successful, though, as the power supply is louder than a traditional unit.
- Silent at very low loadsHigh efficiency
- Passive operation is not possible at 20% loadPower supply is much too loud when switching the fan on
