    Computer Power Supplies (PSU)

    Unless you have very specific training on opening one up, discharging it properly, and the skills to repair it safely for future use, just buy a new one when yours dies.

    This is certainly a case of the phrase “voltage hurts, amps kill” to the best of my knowledge.

    I received the above advice and heeded it.

    My second IT job was filling the role of someone who never received this advice.

        And old TVs, CRT monitors, etc. If you open it up and say “huh those capacitors look a lot bigger than normal ones”, don’t touch it. Put it back together, and leave it alone. Even if it’s been unplugged for days or even weeks, those things can - and sometimes do - hold enough juice to hurt you seriously, even kill you if several decide to discharge at the same time.

      Was doing tours of primary schools and one had a “what’s inside?” Table where parents brought in old broken things for kids to disassemble.

      One of the things was a computer with PSU. Spent my 10min interview with the teacher taking it apart to remove the PSU.
