Is there a fuse inside a PC power supply?
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. That is, unless you have the knowledge to tinker with a power supply and aren’t scared of the capacitators in there.
Is there any fuse in CPU?
There is no fuse in CPU or MotherBoard. The CPU itself runs on 5V and requires very less amount of current to work, so it does not need one.
How do you fix a dead computer power supply?

Do PC motherboards have fuses?
Motherboards use special fuses called polymeric positive temperature coefficient thermistors; in English, this translates into “a fuse that will reset itself.” These fuses protect the motherboard from frying every time a larger amount of electricity surges through the computer power supply.
Why is my PC tripping the breaker?
Either the PSU is failing, or your problem lies elsewhere (the outlet itself, the cable from the PSU to the wall, or the breaker itself). If you can, run an extension cord from an outlet that is not on the same circuit, and see if the issue is repeatable.
Why does my PC trip the circuit breaker?
The problem is that you’ve got too much on a circuit. The extra energy used by the computer when you’re playing games is enough to overload the circuit. You’ll need to identify what else you have on the circuit. If these things are plugged in, you’ll have to find an outlet for them that is on a different circuit.
Can PC power supply be repaired?
Even when the supply is unplugged, its components can remain charged and SHOCK YOU. If you are in doubt about your abilities, let an experienced repair technician do the work or simply replace the entire power supply.
