There are at least two issues here:

1) The designed safety margin is unacceptably low. It should be set such that any cable that complies with the expected safety tolerance for carrying current is safe to use.

2) The late-model Nvidia cards in particular have no feedback system to discover unbalanced current on 12v wires that make up the connector and no circuitry to keep the current balanced even if they did. That is, they forgo any digital control and depend on the physical properties of the conductors to be perfectly balanced.

Overall, Nvidia failed to learn from the melting connector issues in the RTX 4000 series and doubled down by increasing the power draw while further cost-cutting the safety circuitry.

Ok, I have to say this, but the narrator sounds a lot like Jim Henson/Kermit the Frog....(my understanding it is a maryland/mississippi accent combo)
