News Nvidia power meltdowns hit 8-pin adaptors — old power supplies are the common factor

In this case, the 12VHPWR connector was just fine, and the 8-pin PCIe connectors melted.

True, but the card was probably pulling way more than 150W per 8-pin connector. If the card had 4 x 8-pin connectors there would be no melting. It would look God-awful, but still no melting.

Edit - ...looking more closely, it's the 12VHPWR adapter side of the connection that has melted. The 8-pin side looks fine! We need to start making fireman's suits out of 8-pin connectors! /s

While Nvidia doesn't mandate an ATX 3.0/3.1 compliant PSU for the RTX 50 series, it is highly recommended. Outside of the 12VHPWR connector, the newer standards add plenty of additional safety improvements across the board, which this PSU lacks.

I don't think there's any reason to think being non-ATX3.0 is relevant (unless explicitly blaming the use of a 12 pin adapter rather than a native PSU connector).

The only "safety improvements" I'm aware of are specifying the allowed power excursions (i.e. the add in card may exceed its nominal power limit by some amount for some length of time, on the order of milliseconds). Which has to with transient handling and making sure PSU protections aren't inadvertently triggered under normal operation. It's not going to impact connectors melting (given the existing connectors didn't change at all in the spec).
