What is a passive power supply?
“passive” means that the PSU comes completely without a fan, the heat dissipation is completely being taken care of by a big heat sink – which means that the system is pretty much noiseless.
What is the best be quiet power supply?

Does a power supply make noise?
Although all switching power supplies will produce noise, they are usually designed to create noises inaudible to the human ear. If your switching power supply isn’t designed for quiet operation and it’s producing a high- or low-pitched whine or hissing, there are ways to mitigate the noise.
How are active and passive components related to electricity?
Active components such as transistors and silicon-controlled rectifiers (SCRs) use electricity to control electricity. – Passive components like resistors, transformers, and diodes don’t need an external power source to function. These components use some other property to control the electrical signal.
Are there any components that do not need an external power source?
– Passive components like resistors, transformers, and diodes don’t need an external power source to function. These components use some other property to control the electrical signal.
What happens when you use a passive PoE switch?
The power is “always-on” when using passive PoE switch in networks, which means it always sends electric current out over the Ethernet cable at a certain voltage regardless of whether the terminal device supports PoE or not. So using passive PoE switch may burn out the terminal devices if they’re not prepared for electrified Ethernet cables.
When does the passive power factor become a problem?
At higher power levels, however, the size and weight of the passive components become a problem because of the presence of heavier and bulkier filter inductors.
