I'm still on Zen3/DDR4 but right now sure as heck isn't the time to jump from that platform.
It is curious this Zen4 is being released now, and I'm actually surprised it's as competitive as it is (with respect to price/performance and all)
Standard Molex was never immune to meltdowns either - it certainly can happen. Mostly it was with cheap extension cables or cheap no-name power supplies though - so it was easy to point the finger at a manufacturing flaw rather than a design defect.
12VHPWR though - doesn't seem as if anything...
From reading, it sounds like they put a thermocouple in the plug itself. But yeah, just looking at typical amps/volts, nothing there really protects you from high point source resistance.
So I tried this out.

First off - it worked on my 3080. I mean, FPS was about what you would expect (unplayable), but I was mostly just looking to see...
Usually, for electrical fires - air flow often makes the problem worse by spreading the spark/heat out faster
Electrical is usually a high impedance/resistance connection with just too many amps going through it (P = R * I^2), and it's a very small, very hot point source - and that spreads to...
I have been thinking that since RTX came out, to be honest.
I'll admit the "program it once and let the calculations figure it all out rather than leaning on an art department" argument has some merit. But mostly all we got was a lot of very shiny chrome and mud puddles with big performance hits.
