Utilities designed to assess the performance of a power supply unit (PSU) are the subject of this discussion. These programs often provide data regarding voltage levels, fan speeds, and power consumption, allowing users to monitor the health and stability of the computer’s power source. An example of this is a monitoring application that displays the current voltage on the 12V rail of the power supply.
Monitoring the power supply’s operation is crucial for maintaining system stability and preventing hardware damage. Deviations from expected voltage ranges or unusual fluctuations can indicate a failing power supply, potentially causing data loss or component failure. Historically, this monitoring required specialized hardware, but software advancements have enabled some degree of assessment through onboard sensors and communication protocols.
