We're taking here about mains voltage (say 120 V or 230 V AC) power supplies with power ranging from a few Watts to several hundred Watts. Switch mode power supplies are everywhere; here are some pictures of their guts. The big high power components and small heat sinks are typical of SMPS. These devices are incredibly reliable, but being very often left powered all the time (even when their load is switched off), they still are the weak link.
As our new kitchen slowly becomes reality, I am wondering how to protect the cabinets from the heat of the espresso machine. I will be keeping the machine in the corner of the counter top. It does produce significant heat, and of course steam.f so, and you've got the opportunity, you might think about raising the cabinets above where you intend to place the machine. If you can do so, it largely eliminates any heat/steam issues. I refitted my kitchen a couple of years ago, and designed this into it, along with dedicated water/power/drainage.
