PSU mystery

OK not sure if i should post here or in a unexplained phenomena forum but here goes.
My friend was playing on his pc and his power flickered off then back on and his pc went dead and would not turn back on. It seems when the power went it fried his psu as testing it with an odometer shows there is nothing running through it as if the odometer wasn't working.
He then tried a different psu and that one is fried too and after trying several different psu's that weren't even connected to anything and all of them being fried he is on the verge of calling derek acorah.
anyone have any ideas or even a rational explanation for this? any help is greatly appreciated.

P.S. 2 psu's were connected and plugged into the mains and 3 weren't connected to anything.

an odometer is for measuring distance sometimes called a mileometer

so i would love to know what he tested with that

heres the psu paperclip test--maybe that will help

has he checked to see if 1) the socket is still live 2) the power cable is still ok (fuse isn't blown or anything)

anyone have any explanation at all? Still no idea what happend.
