That is some deep sadness there.NVidia digging deeper
No that's not true, it was later found out that isn't the case. Cablemod reached out to Nvidia and they clarified warranty won't be void. It even says you can use a native 12vhpwr cable in the specifications doc.That is some deep sadness there.
If you do not use nvidia's connector your warranty is void? That is insane.
This appears to indicate if you use a ATX3 power supply your voiding the warranty?
An updated article for Igor's Lab. He goes into some of the differences between manufacturers.
12VHPWR adapter for NVIDIA’s GeForce RTX 4090 - Two manufacturers, contact problems, bending radii and the human factor | igor´sLAB
The 12VHPWR adapter for the GeForce RTX 4090 is unfortunately already a kind of running gag and so the topic is meanwhile beaten by all more or less well-informed media.www.igorslab.de
GN got several adapters to melt!!!
Yeah, this makes sense...The connectors not having a positive "click" when inserting them is certainly a design issue. The 6 and 8 pin GPU power adaptors have a click that you can both feel, and hear. The 8 pin connector is also physically more robust.
The smaller a connector is, the easier it is for it to be pulled out by applying any angled stress on it. And really, there was zero reason for it to be so small. Hopefully there is a "version 2" of the connector that ends up having a more positive insertion and retaining clip.
But hats off to GN for doing the right thing. Instead of just posting a video with every new theory like some others, they did all the work, and even utilized a 3rd party failure analysis company.
This 100%. This is journalism, not two-cent reaction videos.But hats off to GN for doing the right thing. Instead of just posting a video with every new theory like some others, they did all the work, and even utilized a 3rd party failure analysis company.

From the looks of it, improper insertion is pretty easy to do. High resistance going in, no positive click, and it can look properly plugged in and not be.TLDW:
Two main failure modes identified (they affect both manufacturers):
1: Improper insertion (not fully seating the socket, then some sideways force to pull it out of alignment).
2: Debris in socket, Possible metallic debris from insertion cycles. Creates an alternate, higher resistance path.
Yeah, this makes sense...
Maybe someone here can enlighten me, but what's the point of this new 12-pin power connector? Is it just so that you can deliver up to 600W in a single, more compact cable than using what would be 4x8-pin power cables? If so, why the heck is it so compact? Could they not have made the outer dimensions equivalent to 1.5x the width of your standard 8-pin connector? Just seems like they tried to cram in 12-pins into the same footprint of the normal 8-pin when we're already used to power connectors taking up the space of 2x8-pins already.

Few wiggles later, some cable routing, and out comes the magic smoke.
It kind of reminds me of all the times that I believed that I plugged the HDMI cable in all the way to only find out that "my PC isn't working" (no picture) because I actually didn't plug it in all the way. 😋 It always has just enough resistance that I think it's good.
Yea lots of people on reddit said they used force, made sure it was plugged all the way in too. I bet there are variances too in the adapter cables where some are more prone to go in easier than others.From the looks of it, improper insertion is pretty easy to do.

Even if the latch is in place according to those who had it melt a few of them did make sure they pushed firmly to connect it properly..some said theirs did not click.There is a latch on the power connector though, so if you are paying attention you can make sure it's latched.

The same GN video also shows how a person can have it look like it is plugged in, and then wiggle it out while cable routing.Those latches often don't make much audible noise, but that isn't the point. If you are seating them, you can keep a finger gently on the latch to feel when it's latched, or you can test it.
GN video shows clear evidence on the damaged user cable they received, that it wasn't remotely close to being seated, let alone latched, and they said you can see similar witness marks on other damaged connectors.
This means, most likely it was a haphazard effort at best. Not everyone installing a GPU really has much clue about what they are doing, or the importance of seating connectors.
sounds like everyone's wedding night.Few wiggles later, some cable routing, and out comes the magic smoke.

LOL. NV isn't in deep stuff. This will go nowhere.
