Yes get a replacement as it could damage other parts of your system
It may be time for a new power supply if your computer keeps shutting down at random times, or gets hot very quickly, you may want to act fast in order to keep from your computer crashing.
A faulty power supply does not supply any power at all to a computer or supplies incorrect voltages. Most of the time faulty power supplies are not serviceable and require replacement.
Yes, it can be faulty. Some damaged power supplies show good output voltages on the voltage range of a multimeter but, when you connect them, they don't work properly. One possible reason is that maybe an IC in its voltage regulator has a high resistance between the common and the output. You cannot see this by shunting a voltmeter onto it. You have to place a typical load onto the output to test it.
Either a dead battery - or a faulty power supply.
Computer not booting
Voltage settings on the back of the power supply should be checked
Either faulty power supply or faulty wiring, the latter of which can either be hot or ground.
There are several reasons for this. Some possibles are below: The thermostat is broken. The electrical wiring/supply is faulty. The fan itself is faulty.
Either the supply or the multimeter is faulty.
Possible Faulty wire or even a starter or alternator failure.
1. wired plugged wrongly. 2 . psu is faulty 3. input supply faulty. 4. motherboard not fitted correctly.
You should not bother to check any power supply in the motherboard. You need to take the motherboard to service centre if faulty.
