Don’t go onto Amazon and order a random cheap ac adapter for any console that you have. They create a bunch of noise on the screen and it leaves a trail of flickering pixels going up the screen.

Learn how to recognize certification marks. In the US, the UL mark is common on electronics, and the FCC mark means that it won’t have RF emissions that interfere with other electronics. In Europe the CE mark is used. I’ve also seen TUV marks apply in both places. However, I have had bricks that worked perfectly well in the US which only had CE and FCC marks.
Your brick had no marks at all, so who knows whether anyone at all tested the design. Many electronics manufacturers simply buy their pre-certified bricks off the shelf and slap their own label on them (keeping the marks), specifically so they don’t have to pay for the certifications themselves
Atleast CE is not really a certification but a “We fullfill these standarts, trust me bro if not we pay” label.
Worse is C E which is just a made in china mark which looks like a CE mark
UL has different versions one of which basically means nothing
Certification marks are just extra silkscreen printing applied at the factory in China. In my field I’ve seen plenty of melted UL marked relays that were clearly cheap clones of the original.
If you’re buying a 5 dollar adapter off Amazon and it has those marks, you can pretty much assume that they mean nothing.
