Semi-passive Power Supplies
Over the years, many noise sources in PCs have disappeared, which used to make working on a computer and especially gaming a very loud affair. Small fans have been replaced by 120mm and 140mm models, hard drives by SSDs, and high-end graphics cards are now dominated by quiet, large axial fans, where tiny radial fans used to "blow." The power supply remains a noise source - although passive variants without fans, and therefore silent, have long been available, they are only available in lower power ranges. However, if a power supply is needed that is inaudible in everyday use but also provides enough power for a high-end PC, there is no way around a semi-passive power supply.
Active Cooling Only at High Load
A semi-passive power supply switches off the fan below a certain power output, depending on the maximum load, for example, below 50 percent load, or depending on the temperature inside the power supply. With the increasing efficiency and the resulting reduction in waste heat from power supplies, it is possible to keep the fan off at higher and higher loads, allowing the power supply to operate silently.
