When you say the power tripped, what sort of trip is it? They tend to be there for a good reason!

Trips tend to be designed to trip if the current gets too high, or if they detected current leaking to earth, depending on the type. Both of these faults are potentially dangerous. I’m wondering if you have incorrectly wired mains, and the connection between desk and computer is allowing a path to ground, causing the trips to do their job, and blowing headphone amps while it does it.

I’d recommend that you switch off & unplug all your audio stuff, until you can get all mains supplies & leads checked by an electrician.
