It’s not even the mains voltage.
There are components in there that can exceed mains voltage when probed the wrong way.
When you start getting into the higher voltages, the body’s resistance is much lower. It only takes a few milliamps to stop the heart.

- kens 5y agoIn the described power supply, you'll find voltages of about 340 volts DC, for two reasons. First, AC is measured in RMS, which is considerably lower than the peak voltage. I.e., 120 volts from the wall swings between -170 volts and +170 volts. Second, this power supply uses a voltage doubler, so you end up with 340 volts DC inside.
- Dylan16807 5y agoDoubling 120 to 240 is still mains voltage in my book, if a supply these days even does double. Sure it's peak rather than RMS, but a warning that something "exceeds mains voltage" to me sounds like a description of a significantly bigger danger than that.
