I see a lot of PSUs on these forums with no input filtering (or very little input filtering, like only Y-caps with no coil or X-cap). Are these PSUs actually illegal, or is it just bad design? I've seen some people say they are illegal in most counties, but if so, why do I see so many here?

I love putting bad caps and flat batteries in fire and watching them explode!!
No wonder it doesn't work! You installed the jumper wires backwards

Re: No Transient/input filtering - Illegal? or bad design?
legally, a device should neither emit nor be affected by harmonics.
that doesn't necessarily mean they need an input filter, but i doubt they'd pass a thorough FCC test.
but i doubt it's strictly ILLEGAL to run those. i can however imagine that *some* insurances would refuse to pay if that thing caught fire (and they could prove it), you'd have to sue the manufacturer or importer for damages.
