We did not have a storm, but on Sunday some major power interrupts, 3 times in a row over about 30 seconds.
My UPS on the pc screamed but the PC just glided through, no problem. Screen did not even flicker.
In the HT room, the FM on and the entire electronics shut down, which is what the Panamax will do for major power excursions.
I powered everything back up and nothing was amiss. No better test than the real world.
