Nvidia RTX 4090 power connectors melting?

idk why CableMod every tried to F with this thing. Should have left it as is lmao. That adapter is way to wiggly and the locking mechanism on the 12vhpr connector is not meant to marry it. It just can't lock in fully and wiggles way too much.

Kudos to cablemods for sticking up for owners when gpu companies don't. The stats are interesting in the thread cablemods have for failures. The burnt connector pic in the post above has a suspicious gap in it indicating it wiggled out.

That is becuase the connector wiggles easily. So you can't really do much about it. if there is any movement, cable, pc it can wiggle out creating gap. Its a bad marriage.
 
Why is this only happening to 4090's and not 4080's since they both use the same connector?

Maybe more people are buying 4090s? Or people with 4090s tend to push hardware more in terms of power limits? I couldn't say. I know my 4090 will do 520W and allows up to 1.1V on the die. I think the newer 4090s only allow 1.07V on the die now, I know I read that somewhere, so maybe there is more to this....?

I've always liked Cablemod and still do, but when this whole fiasco with the original connectors came out for the 4090's they marketed their right angle connector with "Cablemod to the rescue". I have their connector here and tried it a few times with my 4090 card and I didn't like the fitment so I never even powered my system on with the adapter installed.
 
Cablemod is updating their adapters to be compatible with the new specs for the newly named replacement for 12vhpwr, and will offer those at a discount for anyone who bought the v1 of their adapters. The new connectors, both card side and cable side, are backwards compatible with 12vhpwr. The mechanical connection inside the metal female receptacle has had specs upgraded (probably the most significant), some other changes as well.

Cablemod will repair or replace any cards that experience any damage with their 12vhpwr adapters, at the users choice, or use the video card vendor. Pretty solid service from what I've seen.
They said so far they've sold 80,000 adapters, and 80 users have experienced problems. 1 in 1000 isn't huge, but in comparison it is a lot more than they see with their other products.
 
That's back from when the problem first cropped up. At the time, we all agreed the connector was not plugged in correctly. The current problem is that the connector is too loose relative to the old style and that anything except a perfect plugged in neutral strain on the connector situation can raise the risk of melted connectors significantly.

I think the take we can get from the whole connector fiasco is that we have a beefy sized card and cases that cannot accommodate a cable that juts out as much as the minimum 35mm due to the size of the card on top of that. We also have scenarios now where just the weight of the cable or a wire placement where there's a side load applied to the connector can also trigger fire risk.

The proposed solution is a newer style connector which improves the contact of the pins, improves the latching aspect, and provides a bit more meat to the physical connector to be more solidly plugged in.

I don't think my setup will ever see a problem because I'm using the 180 degree adapter and my video card is vertical. The cable while pulling down is stiff and placed in such a way that it actually is not really applying any tugging force while having the most gentle bend across 15cm to go into the back of my case. Anyone running the card in a normal orientation without the side panel spacing needed is pretty much at risk if care isn't taken to ensure no side loading of the plug.
 
CM is marketing a new beefed up 90 degree cable.

So, after I bought my 4090 I ordered a CableMod adapter when the orders went online. Mine was delayed byt I eventually received it, but I have never installed it, as I didn't have it when I was finishing my GPU install.

I was planning on doing so when I had a spare moment.

When I originally installed it, I did so in kind of a loose loop to avoid tension problems, and I made sure that it was fully inserted.

The loose loop has since on its own shrunk a little bit, but still does not look like there is any real tension on the connector.

I haven't had any problems yet, though I haven't really pushed the GPU with any overclocking.

At this point I'm not sure if I'd make it any better or worse by installing the cablemod adapter, seeing that some have failed even with the adapter installed...

Choices choices...
 
Recently purchased 4090FE's from BestBuy in late June have a connector with shorter sense pins. Unclear yet if its the entirety of the new spec.
 
You can all keep your shorter sense pins on your newer 4090s, ill enjoy my 1.1V voltage and longer pins vs. 1.07V and shorter sense pins!!!! 😁😉
 
Jay actually did a really good job explaining the new connector. Much better than expected.

The changes were made due to user error causing issues. You can blame PCI-SIG for not foreseeing such stupidity. They must have been working from assumptions in design made 20 years ago before the collective intelligence of the human race went off a cliff.

Pretty sure he said that it was user error, but that a good connector shouldn't be allowing for user error like that in the first place, which isn't the same as what you're implying.
It will be funny to see how actual nV bootlicker channels react though.

I didn't follow his coverage on this topic, but I was about to say that if he said what Ranulfo suggests, he lost a lot of respect from me.

doubletake Thanks for the clarification, this makes much more sense knowing his past content.

No, but still more than they'd probably like to see. While you are never going to eliminate issues/defects, you'd like to keep them even lower than 1 in 1000 if you can. If better connector design can push it down to 1 in a million, or 1 in 100 million that would be a win. Things that help prevent user error that causes damage are good.

An example from another area would be the SawStop. This is a system for table saws such that if your body touches the blade it triggers a system to drop the blade down and stop its rotational movement in a fraction of a second. This destroys the saw, but saves your finger. Now this should never be necessary, in theory. You should never put your fingers or other body parts in such a position as to make contact with the blade. Its user error when it happens. But it does happen, and a design that makes it less serious is a good thing.

Same kind of shit here. Should people plug in their connectors, and not just this one, carefully and check that they are flush? Yes. Should they only put 4090s in cases big enough to have adequate space for the cables to be installed unobstructed? Yes. However they aren't going to do that, so to the extent possible, things should be engineered to tolerate that.

I'm not going to get up and hate on nVidia, Molex, PCI-SIG, or anyone else for the new connector, I can completely see the reason to not only want a high-power connector, but one that takes up less space. I'm also not going to hate on them trying to improve it after there have been problems in the field. Sometimes, you gotta go back and do more engineering because of the average person.

Do you know how many incidents it takes for the NHTSA to initiate a recall in certain cases? I think one of the unintended braking (or maybe acceleration) ones was like 7 cars.

And what the fuck does the National Highway Traffic Safety Administration have to do with graphics cards?

CPSC would handle this not the NHTSA and it doesn't seem to be on their radar yet. Not until someone actually gets hurt, not youtubers forcing it to happen for clicks. When all those 3d printers with non UL power supplies and bad wiring were causing fires they only ended up releasing a statement as a 'buyer beware'. So i doubt anything will come of this because it is such a small occurrence and user usage is part of it.

A lot of it comes down to personal safety, if no one has been hurt then no acronym agencies will have any real involvement.

The reason it's on no ones radar is because it has only happened to a handful of users and it has been proven to be user error.

I already figured it out. In case my post was unclear to you, the NHTSA has fuck all to do with GPUs, so brining it up is about as asinine as it gets.

No, you clearly didn't. Since you completely missed my point, let me spell it out for you. Saying "a small percentage of dangerous things doesn't mean it's a big deal" isn't true, as evidenced by the fact that a government organization in charge of safety--things like "your stuff not catching fire"--went after a manufacturer with *7* instances of the bad thing. To help, 7 is much less than 1000.

So, I installed a couple of m.2 drives the other day, and that meant the GPU needed to come out anyway, so I decided to try the cablemod adapter...

So, looks like it won't work due to the power slot being recessed into the EK GPU block.

So glad I spent that $39.99 on an overpriced cable adapter.

It looks like it still has a clear plastic shrinkwrap on it...

Take that off and try again just to be sure.

One thing, if the connector on the card is recessed, you probably don't need the angled connector other than for aesthetics.

It does. I figured I'd keep it on there just in case I sell it (which isnt likely for something that is only $40)

It is difficult to take a picture that illustrates the lengths involved, but when holding it in your hand it is pretty clear it is never going to fit, even without the shrink wrap.

If you look at the top one, the distance from the bottom of the black bridge part of the adapter to the bottom of the connector is about half the distance from the edge of the plexiglass and the bottom of the connector it needs to be pressed into, so it will never reach.

On the flip side, EK may have actually done this to provide some protection for the cables so they don't get pressed sideways straight out of the connector, which is a positive I guess.
