Does PSU have a fuse?
Power supplies have one fuse. But it’s soldered on, so you’ll have to get a new PSU anyway, even if the fuse is just broken.
What is the use of fuse in power supply?
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
How do you fix a faulty PSU?
Plug the PSU power cable into a wall socket or surge protector, and turn on the computer. Most power supply models have a light on back of the unit that glows when it’s powered on. If it doesn’t light, try a different power cable and a different socket to eliminate those items as the source of the problem.
How do you check if a fuse has tripped?
