Perhaps so, but these power supplies are few and far between, so we'll have to see about how these actually perform in the long run.
However, you're missing the point. The spec should be designed such that even "non-reputable" manufacturers with sloppier manufacturing methods wouldn't create a fire hazard. These connectors are extra-delicate even though they're supposed to carry higher loads. They will be less robust in practice, for very little gain. That's a poor tradeoff, which makes it poor design.
I am not here to defend Nvidia, nor the quality of the design, I’m not in anyway capable of judging it on it’s technical merits. I think this debacle is a farcical mess.
These new adaptors are included with products Nvidia themselves ship, with themselves as OEM. They know this standard is not common, and they know they need to ship adaptors with them, If they can’t guarantee the quality of it’s manufacturing, then it says there’s possible more worrying things going on behind the scenes.
