Final answer:
Symptoms of a bad power supply include overheating, frequent power outages, random restarts, and unusual noises.
Step-by-step explanation:
The symptoms of a bad power supply can include overheating, frequent power outages, random computer restarts, and unusual noises from the power supply unit (PSU). Overheating may occur when the PSU or associated wiring is overloaded with too much current.
Causing excessive power (P = I² Rw) to be dissipated as thermal energy, which can lead to dangerous thermal effects. Frequent power outages and random restarts might indicate that the PSU is unable to consistently deliver power to the system.
Potentially because of electrical shorts or issues with voltage stability. Unusual noises such as buzzing or clicking could signal a mechanical or electrical fault within the PSU.
