The vicos one - actually one of 2, but it is also powering some other things, and I think it is too much.
The problem with a split power input like that on an isolated supply is that no voltage is perfect, so one of the sides will provide slightly more power than the other, and then at some point if your PSU is already flat out, one side shuts down because it is too hot leaving the other one to do all the work, which doesn't last long.
Probably need to run two psus.
Yeh, the uk plug comes off as it is only held on one side, a bit of a poor design
