Default EMP

Just in case you thought I was a nut on the subject of EMP I invite you to peruse this page. In the middle of it there is a disquisition on the subject of EMP. In fact, the manufacturer of the Hummer expects to make money from the fear of/respect for EMP. So, is this a potential marketing element for PSU OEM's (EMP is most likely to enter an electronic device through the AC line; PSU's stand astride AC lines) or would a bad EMP kill the mains so that there would be no power? Would it be useful to protect electronic devices such as computers? (Don't talk about Faraday cages protecting your computer because the danger will come though the mains, bypassing the Faraday cage.)

I don't think you need to worry about your PSU when an EMP goes off near you...

That would be the least of your problems...

If the EMP is from a nuke, yes, but that is just what Kim threatens. I would be more worried if it were from a non-nuke source -- that would mean someone nasty is close. Realistically, though, I worry about a blob of ions from the sun -- another Carrington Event.

No, in general.
All Components needs to be "EMP Shielded", not just the PSU.

That's what I've meant.
Also if you have a HDD, the data on it is probably gone as well...

Agree. Bu8t we have to start somewhere, and the PSU is exposed to line voltage. The other equipment in a system are arguably protected by a Faraday cage. But if the PSU lets a shock through, it will fry the other components.

Yes, but what you are talking about isn't an EMP, it's a Surge. And that's what PSU are already designed to withstand. At least 2kV.

And c't tested it a couple of years ago (when I still took a look at their magazine)...
Many quality PSU withstand those surges or die without killing other components...
