And the side bit about surge protectors and lightning strikes....electricity can follow very very strange paths, and do damage to things other than the PSU.
From a recent nearby lightning strike, items that were killed:
PC - ethernet port
Printer - ethernet port
Stereo receiver - 2x HDMI ports
Invisible Fence circuit board - Burned, and the cover blown halfway across the garage.
This is in a 1980's house with good quality wiring and circuit breakers.
The pc, printer, stereo were all on high quality UPS's. Different ones.
PC and printer were separated by 2 switches and a router. None of which were affected.
The devices the receiver were connected to via HDMI (TV and HTPC) were not affected.
The invisible fence was physically unplugged from the wall. My ex had installed that years ago, and it had not been used in many years.
In none of the multitude of devices in this room, were any of the power supplies cooked.
A couple of the PCs rebooted, and came right back up.
And for those who say "I always unplug my PC if there is lightning..."
For every storm with lightning, there is a 'first one'. This was that.
It was rain rain rain BAM.
If I were to unplug everything every time it rained, devices would be OFF more than ON.
