UL puts effort into power supplies. This has been a problem with desktop machines for years. Gamer sites which review power supplies note that UL-rated power supplies don't burn out or blow up. That's because UL tests them by loading them up to their specified output with a resistor bank and running them for a few days at 100% load. They also test the overload-shutdown features. There are many low-end desktop power supplies which will not deliver their nameplate output continuously, or at all.

You cannot officially be CE certified by a third party, but once you slap on that logo you are very liable if you don't live up to the standard.
If they're designing potentially unsafe equipment, I promise you that trademark law wouldn't warrant a first thought, let alone a second.
And I'd appreciate if you leave out the condescending tone.
If I buy something and I find out it was illegally on the market place then I can complain to the seller and get my money back (in theory)
That doesn't mean I don't think it's interesting to know.
Not every country has an interest in enforcing US trademark law. Also, some interpretations of US trademark law can often be seen as excessive and/or hostile by other (western) countries.
