I hereby submit an alternative name: dildo-gate, because the cable is stiff and you SHOULD NOT bend it!!!LOL, here it comes bois, I coin it pin-gate:
The example of the molten pins in the vids were from a vertically mounted GPU with very slight bending far from connector.
Cablemod is working on a right angle adapter that can be used in conjunction with the adapter cables Nvidia cards come with in the box.

I can't find my p600s case accessory box that has the vertical mount adapter but I would imagine even that would cause horizontal flex in the Nvidia adapter cable?I recall the vertical one going to the Gigabyte 4090 having a decent amount of cable droop likely caused by the weight of the adapter. That's why it seems like there needs to be some sort of support. It's also why I was surprised that the CableMod cable's flange wasn't an actual support, or at least that's how it appears based upon those images. I'd be tempted to grab a Velcro tie or a zip tie and use the flange as one.
EDIT:
Even though I'll vertically mount when on water, I'll probably grab one so long as it isn't prohibitively expensive. (The Global store appears to ship from China, or at least that's where my cables came from.) I'd rather have that available if I need it rather than have to wait!
Even 8-pin PCIe connectors have had failures like this. Not sure this isn't anything other than user error or simply a bad plug. Stuff happens. When we see droves of them coming in then we might be able to assume this is an issue.
IOW, put down the pitchforks for now.
How are the pins on the new connectors configured? Do all the ground and 12V pins go to common planes, or are they separated on the GPU so that it can try to force equal current through each pin?
Looking at a couple board shots, it seems like the 6 pins go into a single plane. That's kind of what you'd expect, though it's different than it used to be where generally each 8 pin power connector was a separate 12V input and fed specific phases of the VRM.In reference to my earlier post, and based off my experience with power delivery testing/engineering, the load is likely not being evenly distributed across the 6 power pins. But I do not have any proof, as I have not tested any of these. Its still possible that the power draw is even, but one of them is higher resistance, and because we now have fewer pins handling the same power, a high resistance pin is going to generate a lot more heat than it would with four 8pin connectors.
That would be up to the card designer, but there isn't a good reason not to route all 12V pins from the connector, to the same power plane, wouldn't be a PCB routing issue when they are all adjacent on the same connector.How are the pins on the new connectors configured?

So the design of the 12VHPWR is perfectly fine under perfect conditions. Problem is manufacturing quality inconsistency allows too much room for problems to occur. Dont they take such things into account when they design things like this? FFS!
Aris puts a 12VHPWR cable through testing. He said old 12 pin hit 100c and was fine, 12+4 Straight 55c, Bent 57c. 505W sustained and he's not concerned, suggests poor connection increasing resistance and therefore more Amperes flowing through a poor connection. Could it be just a bad batch of cables, user error plugging the card in? He is going to do more tests when Asus send him a 4090 and using proper methodology reach a conclusion that isn't a knee jerk "Ngreedia bad" but a reasoned data led reason.

I don't see how Nvidia couldn't have encountered this issue in their own labs, because I highly doubt they tested the GPUs in perfect conditions either. Nvidia engineers are still normal people who just plugged in the 12-pin cable without much thought regarding minimum bend radiuses, etc, and they probably tested a reference card inside an actual case, not an open air rig, to determine if the reference cooler was satisfactory. Any kind of long term testing would have hopefully exposed the power connector issue.So the design of the 12VHPWR is perfectly fine under perfect conditions.

Nah, most likely liability reasons. Don't want a fire because of their faulty adapters and such.Money most likely. It would have been an extra 75 cents per unit or whatever number.
I think that connector is OK if it were rated at less power. For cards in the 300-350 watt range and no more than 3 x8-pin cables connecting to it. For a 4090, I think they should have 2 of them with no more than 2 x8-pin cables connecting to each to more evenly balance load.I would never use that connector out of principle. If all it takes is a little uneven loading to make it melt, then screw that thing forever. My OCD would eat me alive with that in my case.
I would certainly not feel very comfortable using it and a $1600++ card.I would never use that connector out of principle. If all it takes is a little uneven loading to make it melt, then screw that thing forever. My OCD would eat me alive with that in my case.
