Teardown of a PC Power Supply

Simplest solution is to discharge the power supply: i.e., flip the switch on the power supply and then try to turn on the PC/electronic/whatever. You'll discharge the vast majority of the energy while it attempts to power on, leaving a relatively safe working environment. No tools needed.

Unless it doesn't, because the power supply is faulty.

This.

Additionally there are typically bleed resistors to drain capacitors to safe levels, but they can also go open.

Dont use this as general rule. Its quite easy to find electronics that uses a master/slave approach. If master is down, slave won't connect, but you may still have the capacitor bank charged. Usually there should be a shunt resistor to discharge capacitors, but you'd be surprise how often is missing.

Or better yet, just unplug the computer while it's on /s.
