The ones I tested so far are that bad.
You don't need to destroy. A leakage tester may work, or 300V via 2 M Ohm. May need to be running on mains to fail. I'll check some more with unpowered leakage test and then powered.
See also RFI via offical tests on LED built in PSUs and electronic Ballasts on CFLs. The test setup is unrealistic compared to separate L & N wires daisy-chained and switch wiring.
Then there is networking over mains. They test either one unit (thus no communication), or without ethernet. They don't have SMPSU interference as that is well filtered so that they work. They can knock-out DSL and faster ones have RF to over Band II (into Aircraft band).
Then also there is no in market testing. So I've seen PC PSUs with wire links for inductors and capacitors missing, so as to save costs.
[You mean Samsung bought it with Samsung branding or did Samsung really make it?]
