Is it possible to connect 12V lines in series from 2 different PSUs connected to the same outlet to get 24V with the same current?

Question

Power Supply

If it's not possible, please explain why it won't work.

Answer 1

Yes, it is possible, with some precautions - for example, it is impossible to allow the cases of these PSUs to come into contact, since in computer PSUs a common output wire is connected to the case (minus all output channels). With such contact, one of the power supplies will be short-circuited, and short circuit protection will work in it.
