But if you are wearing a metal watch, ring, etc, and get one of the supply rails shorted through it to ground or another supply rail, the supply will give all of the amps it can (usually much beyond its rated output, at least for seconds) through that metal. It can't electrocute you, but the metal can heat up enough to cause a serious burn. With a ring, potentially serious enough to lose the finger.
Lesson: remove watch and hand jewelry while working inside computers. Even PCs.

@brouhaha @fae @lynn The designer of the Rational R1000 told how his engineering-ring once shorted pins on this backplane. https://datamuseum.dk/wiki/Fil:R1000_s100_Backplane_2.jpg Those grey metal blocks at the bottom is where you bolt on the AWG 3/0 cables to the power-supplies, each of which is rated for 200A.
