The big TLDR is that the issue with the adapter is the connector's poor quality construction that leaves it fragile and easily susceptible to being damaged.
Combined with high amperage, the bending of cables and a user not be ultra careful with plugging in the cable, can result in hot spots that heat up enough to start melting the plastic.
The salt to the wound is that PSU manufacturers' 12VHPWR adapters are safer to use because of their more robust construction.
> A good example of a functioning connection are, for example, the two 12VHPWR cables of the new be quiet! Dark Power Pro 13, which I still show here as an example. Because there you don’t have to do the balancing act with the voltage bridges, but spend each pin its own 16AWG line. Sure, 12 thick wires in one cable is not that sexy now either, but it is at least an accurate and clean solution. I also snapped these cables right at the connector several times and did much of my testing for the GeForce RTX 4090 as well as the Intel Core i9-13900K in the lab with them on the redundant test system.

> The overall build quality of the included adapter for the GeForce RTX 4090, which is distributed by NVIDIA itself, is extremely poor and the internal construction should never have been approved like this. NVIDIA has to take its own supplier to task here, and replacing the adapters in circulation would actually be the least they could do. I will therefore summarize once again what has struck those involved (myself included) so far:
> - The problem is not the 12VHPWR connection as such, nor the repeated plugging or unplugging.
> - Standard compliant power supply cables from brand manufacturers are NOT affected by this so far.
> - The current trigger is NVIDIA’s own adapter to 4x 8-pin in the accessories, whose inferior quality can lead to failures and has already caused damage in single cases.
> - Splitting each of the four 14AWG leads onto each of the 6 pins in the 12VHPWR connector of the adapter by soldering them onto bridges that are much too thin is dangerous because the ends of the leads can break off at the solder joint (e.g., when kinked or bent several times).
> - Bending or kinking the wires directly at the connector of the adapter puts too much pressure on the solder joints and bridges, so that they can break off.
> - The inner bridge between the pins is too thin (resulting cross section) to compensate the current flow on two or three instead of four connected 12V lines.
> - NVIDIA has already been informed in advance and the data and pictures were also provided by be quiet! directly to the R&D department.
> Actually, I wanted to do something completely different today, but this correction was more important to me. Blanket panic and gloating are really bad advisors here when it comes to introducing new standards. That AMD has not (yet) joined the plug change was shown in my news about one of the upcoming board partners. But if you, like NVIDIA, take such a radical step, then at least the included accessories should work properly over after a little bending and ensure a safe, stable operation of the graphics cards.

Amazing to make such a high end product and to imagine all the man hours spent in design and construction just to skimp out on the thing that powers it. NVIDIA really has its head up its own arse. Way up there.

Calling Chevrolets 15 cent ignition spring that caused ignition interlock on the first gen Cobalts.
They saved 10 cent per spring from the factory…guess how much the recall costed the company, along with the PR nightmare is created.

Or Ford's Pinto moment.
Or when Takata decided it would be a REALLY GOOD IDEA to ship claymore airbags and defective seat belts to car manufacturers around the world, guaranteeing that when the scandal breaks, they would be sued both by consumers and the car manufacturers.

> During 2013, several automakers began large recalls of vehicles due to Takata-made airbags. Reports state that the problems may have begun a decade before,[11] with the faulty airbags placed in some Honda models starting in 1998.[12]
...
> On January 4, 2019, Ford issued a recall for an additional 953,000 vehicles, including 782,384 in the United States and federalized territories and 149,652 in Canada. Affected vehicles included 2010 Ford Edge and Lincoln MKX, the 2010 and 2011 Ford Ranger, the 2010 to 2012 Ford Fusion and Lincoln MKZ, the 2010 and 2011 Mercury Milan, and the 2010 to 2014 Ford Mustang. This was a planned expansion of previously recalled vehicles as identified earlier by the NHTSA.[42]

Nvidia doesn't manufacture them. It's WAY more likely, as these don't meet Nvidia's published specs, that the manufacturer screwed up.

Sure, Nvidia is the type of company to not pass blame.
kdavis37 t1_iu49tao wrote
That's utterly irrelevant. Nvidia released a spec. This breaks that spec in multiple ways. You don't go through the effort and cost of finding your minimums and then go under them.

You know, I would really hope that the big issue is just poor quality connectors, getting an aftermarket quality plug would give a lot of people peace of mind, not that they shouldn't still be cautious since we are still the guinea pigs on the new standard

1600 better come with gold plated connectors and a BJ while I insert it in the case, I'm going to need even more for the 2k model.
I'm guessing we're definitely not getting what we pay for this generation.
