Out of curiosity, I'm starting to wonder about the little power bricks. They are all SMPS, and I see a lot of them failed after about 2-4 years. They do get quite hot- I've yet to rip a failed one apart, but I'm wondering if we are looking at capacitor failures. A lot of these power supplies are very cheap, and they have everything working against the capacitors.
They run very very warm, the output ripple on these from what I've seen is quite high- 100-150mV seems to be not uncommon. I really would like to see some pulled apart to see what we are looking at. Do they use good quality capacitors? Or are we looking at super hot, confined environments with lots of ripple being handled by the likes of Jun'fu, or G-Luxon (are they even still around?). That might explain why they don't seem to last very long.
Anyone have any they've pulled apart they can provide any input on?
