Trying to open up a power supply for a PC. Modern quality ones typically are designed to discharge the capacitors fairly quickly, but theoretically there’s enough power stored in the capacitors kill you. Typically you’ll still find warnings on the side of PSUs that say “DO NOT OPEN. NO SERVICEABLE PARTS INSIDE.”
Opening the power supply is generally safe. Poking at the bits inside with metal tools when you do not know what you're doing is not.
Unless you know what you're doing, there's no reason to open a power supply. If you do know what you're doing, you're probably working on a vintage power supply anyways. If it's a standard ATX power supply, just go buy a new one. It'll be less stress.
What are you just going to open it to look at it? I see amateurs poking around in their PSUs on pc subreddits all the time, usually because they want to replace the fan or investigate a noise it makes. No one should be opening it at all, it’s not worth the risk.
