It is a H777 PSU.
You sure know how to pick them. First you have an H7140 that has startup
chopper problems and now you have an H777...
Anyway, the first thing to do is to check the fuse (in the obvious holder
on top), then to see if it prodcues any outputs and if the internal relay
operates. That relay is part of the inrush limiter circuti and you can
have soem very odd problems if it doesn't work.
