Do you have proof that claims are denied due to power supplies not rated correctly? That seems like fear mongering otherwise. Your insurance still covers your house even if you make mistakes on construction or repair yourself, I can’t imagine them denying a claim over a purchased part that you have a good faith reason to believe it will function correctly.

Also why do you specifically call out Chinese parts as being shitty? Where do you think the majority of electronics come from? This feels like xenophobia. The power supply can be cheap and crappy and come from anywhere. Or it can be great and come from anywhere. That one you linked, by the way - Made in China.

I clarified in a sibling comment, I was incorrect about UL listing being required for homeowner’s insurance but UL listing (or testing by another nationally recognized test lab) is required to pass an inspection if you’re hardwiring a piece of equipment, and fires caused by unpermitted DIY electrical work are not covered by insurance.

Amazon does not have audited supply chains. The power supply I linked is sold by Sylvania, it has a warranty, and it’s UL listed, not sold on Amazon by Xfrtteg or Psygwist. You can have quality goods manufactured in China, it’s Amazon that I don’t trust.

OP is making a distinction between directly-sourced parts, versus those commissioned by a Western or Western-affiliated company that’s gone through the “trouble” of a CSA/UL certification. One is built to a price point, one is built to limit liability.

My understanding is that insurance will not cover issues caused by DIY work if you did not have it permitted and inspected properly afterward. I sincerely doubt that an insurance company would be required to cover losses due to DIY electronics using parts that have not been properly safety rated. I'm surprised you think the opposite is obvious. Could just be my US perspective.

I fully expect that if I built (or bought) a power supply, plugged it into the wall, and it caught fire due to my own negligence (unintentional), that the resulting losses to the structure would be covered. (I'm in the US.) It would seem no different than if I built a fire in the fireplace that caused the issue, had a 3D printer catch fire, or had a grease fire cause the issue.

I would be shocked if that's true, considering here in Texas you don't need a permit or inspection to do DIY work on your own house.
