Anecdotally, RAM failures are more common than they used to be in previous decades, I assume due to increased capacities and smaller process nodes. Looser manufacturing standards may also play a part.

The component category I've never seen fail is CPU.

I've worked in and around datacenters for a few decades now and I've seen pretty much everything fail, but power supplies in particular do so at a higher rate than I expected. I've had one literally start smoking in my home office recently too. Luckily, it didn't damage any components, but it was pretty dramatic and abrupt -- just powered on my desktop and got nothing but a fog machine coming out of the rear fan until I yanked the power cord a few seconds later.

My evga 1000w has been going strong for 11 years now. Cheaper power supplies fail often but if you buy quality and oversized they’ll outlast all your other components as they don’t become outdated.

It’s the caps that fail. Electrolytic caps have the highest failure rate of any passive component. My team tries to avoid them in our designs as much as possible. But you’re right, caps in a good design can easily last 20 years, making a power supply the longest lasting component of most builds.

My go to source for reviews was always jonnyguru.com but he closed up shop. Not sure who’s actually doing in-depth performance and component reviews these days.

Had the EVGA 1000w fail on me. It did not fail dramatically though, rather it refused to output high power. Got a replacement under warranty

What brand of power supply?

The CPU can fail if the heatsink falls off! That is something that happens (I've had one come off in my hand that was being held on by nothing but hopes and dreams, fortunately not while the CPU was powered on). More likely in a desktop tower form factor.

You didn't hold on to your Pentium 4 long enough. :-)

My main machines were PowerPC G3s/G4s/G5s back then with the P4 boxes I had taking secondary/tertiary roles, so that lines up.

Anecdatum, but mine still works :D
