Testing results (Efficiency, Noise & Thermal)

The Silverstone ST75F-G easily honors its 80Plus Gold certification, reaching well over 92% efficiency at 50% load when powered by a 230VAC source and 91.5% efficiency if the input A/C voltage is reduced to 110VAC. The efficiency remains above 88.4% when the unit is powered from a 230VAC source and over 87.6% if the A/C voltage is reduced down to 110VAC.

The thermal performance of the ST75F-G was mediocre, with the temperature delta going over 12°C at full load, a significant difference considering the cooling system and efficiency of the power supply. Although the temperature is not very high, it is considerably greater than that what we would expect any similar unit to reach. However, there is a perfectly reasonable explanation, as you will find out in the next paragraph.

The very conservative cooling profile which Silverstone programmed in the thermal controller of the ST75F-G power supply explains the mediocre thermal performance. It would appear that as long as the temperatures are within safe limits, the controller does not even bother to speed up the fan. As a result, the ST75F-G remains entirely quiet even when heavily loaded, reaching audible levels only if the load exceeds 90% of the unit's capacity.
