I'm having trouble remembering what they're called, but I do remember reading about these. I saw a demonstration where they slightly pulled at the desktop power plug in order to hook a thin device around the plug connectors to provide power, and then they could transport the desktop around.
Actually not because a server with multiple PSUs definitely knows when one loses power. Itβs made to raise alerts about a power rail failing. So this makes it harder because you need to keep power on both to not raise any alarm
