A PC technician should work inside the power supply when troubleshooting power-related issues, such as the computer not turning on or experiencing intermittent power failures. Additionally, they may need to inspect or replace faulty components like capacitors or connections. However, this should only be done if they have proper training and tools, as power supplies can store high voltages even when unplugged, posing safety risks. It's often safer and more efficient to replace the entire power supply rather than attempting repairs.

What type of power supply connector is used to supply power to the floppy drive light remains lit constantly How should the technician attempt to repair the problem?
The drive appears to be a bad one. Why do you need a floppy disc drive anyways?
What are the challenges in power supply repairs?
I'm sure someone can elaborate on this answer but there is a major aspect of safety involved if you are taking a computer power supply apart, that being the large capacitors inside hold a substantial amount of charge that are enough to give you a nasty shock, so you should drain the power from them before you go poking your fingers inside. Of course you would never do it when the power supply was switched on!
What power supply should you replace a 175 watt power supply with?
any power supply with at least 175 watts

What danger is posed to a technician by opening a power supply even after it has been unplugged for an extended period of the time?
The capacitors in the power supply may still be 'charged' - and give off a powerful shock if touched.
How many fans are typically in a desktop case?
