Arc what is the brand of the power supply that the lighting destroyed?
The reason I ask it might of saved the rest of your computer.
The lighting hit close; how close is close?

A long time ago lighting struck a house of a person I knew. The house was even equipped with lighting rods. The lighting melted a surge protector, blew two computers up and all the phone wiring and went through a wall and blew a 6 in hole in a old iron bath tub. Presumably went to ground through the bath tub pluming.

The insurance investigators said the lighting came through the phone lines.

I asked them then and I still don't understand to this day how that can happen.
You would think that lighting would melt the phone line like a fuse before it could ever pass all the way through it. All they knew was it happens and is why they inspect claims to see for real what happened.
My phone line does go through a surge protector and I never want to find out how well the surge protector works.

That is why them call them surge protector and not lighting protectors.

That is a good point. Surge protectors have a device that clamps high voltage spikes. But while doing this the device itself may be damaged such that it no longer functions. Such damage is usually not visible. As the PSU was damaged that would seem likely. Of course the surge protector may have been damaged during a previous storm and was no longer working.

Incidentally devices called "surge protectors" are really spike protectors. A spike is very high voltage but lasts only for a few milliseconds. A surge is much lower in level but may last for several seconds. Protection from the latter is expensive but the problem is uncommon, except in some areas of developing countries.

The PSU was uMAX.

I dont know exactly how close the lightening hit, but it was very close. My room flooded with lights and my computer turned off. Then I got the loud sound. It felt like it hit my head but actually not. It fallen somewhere in the wetland that is surrounding our village from three sides.

Risky if you are switching PCs off this way, unless they are already powered off.
