I concur. A lot of “flakey” issues can be traced to poor quality power supplies. That’s a component that doesn’t get any attention in spec sheets other than a max power rating and I think a lot of manufacturers skimp there. As long as the system boots up and runs for a few minutes, they ship it.
Definitely that too, particularly in 2nd-world countries. I remember having a difficult time with dirty power for some hardware products I was responsible for at one time, where the customers were in the Middle East nd Africa in the 1990s. We ended up having to have the PS manufacturer do a redesign to help compensate for dirty power. It can be done, but it costs a bit more.
