Issue with power supply unit.
Issue with power supply unit.
You notice signs like unusual noise, reduced performance, or temperature spikes indicating overheating.
Computers tend to generate heat. Is there an eco mode option on the power supply unit? If yes, you might attempt to disable it to check if the fans activate. If the fans remain inactive, it could indicate the PSU needs replacement, as suggested by @Chapunna.
What is the specific build and model? Are there any actual problems with the computer that indicate this could be an issue? It’s not wise to guess it’s just low-quality hardware without knowing more.
