Discussion – The story of the connectors melting on the GeForce RTX 4090 continues. A Corsair expert found another cause: Živě.cz

Until T-Dean connectors were on the market, model makers used these connectors as well. I had them a few years ago. And the quality of the T-Deans is very different, I bought a couple from China and not only do they not transfer currents, but sometimes they completely lose contact. I also have a couple of Chinese iksteks, I wouldn’t use them anywhere either. Quality issues affect all connectors.
“At the same time, it was enough for NVIDIA to use a connector with multiple pins and then split the current draw across multiple pins and thus reduce their draw, which is a common practice and the cheapest and safest way.”
But nVidia didn’t invent the connector, do we know that? It used a standardized connector. And the problem, the cause of which is still unknown (!) in my opinion, lies precisely in what you write; more pins. Once you don’t click the connector, more pins have higher transition resistance. And the pin that does not have it then captures all the current. So I dare to see the fault also from the side of the sources, which simply have all octaves connected electrically, and flowing through the one with the lowest resistance, logically. So far this hasn’t been a problem, as few cards have two eights and even then don’t push them to the limit; more cards were expected to be used and there are no such issues. This, I believe, is the solution for the future.
“Older graphics were done this way and there were no issues.”
Older graphics didn’t need 600W.I’m sure exactly the same problems would occur, for the reasons I described above, with three 8-pin instead of one 12-pin.
