To be clear, I am not saying Cablemod adapter caused issue.

They were losing money on that adapter, by sending cards in for repair. Plenty of other cables connectors melted too.

Wait what? That's a pretty backwards way of looking at things.
The name of this thread is "NV 12VHPWR issues revisited". We had heard a few reports of molten connectors in the early weeks of the 4090 release. Then guidelines were issued by Nvidia about ensuring the connectors are properly secured during installation. Then reports of molten connectors tapered off for a few months then suddenly spiked again. That is about when Cable Mod began selling their adapters.

Cable Mod have sent many cards to Northridge Fix (as well as Kriss Fix in Germany) who refurbish the cards that were damaged due to their connectors. Pretty sure that has a lot do with NRF reporting he fixes about a 100 4090s per month .. Sure, a few may have melted without CM adapters, but I believe the vast majority were with these adapters (CM have sold about 25000 adapters).

Again, why the lull in molten adapter reports until this "revisited" thread in May when CM were in full swing selling their adapters.

The entire spec is faulty, it wasn't just Cable Mod adapters. Cable Mod pulled their adapters because they can't find any way to make it safe even with the cable seated correctly. The whole point of the adapters was to make it much easier to seat the connector and to reduce cable bends.

If these repair shops repaired cards only or primarily because of the Cable Mod adapter they would have said so. Where's the evidence of your claim that "the vast majority were these adapters"?

I get that you have an issue with some above quoted posts, I don't need to name them.

But the issue is not cablemod adapters, the issue is the 12vhp connector itself.

I would agree with you that there are not as many 4080 melted connector problems, as it doesn't pull as much power as a 4090. But the insertion force required would cover the range of products with this connector, yes?

I do not know what die is used for the 4080 Super, but if the amperage through the connector is increased by using further cut down 4090 dies, then problems will start to appear as time progresses right?

Using just North Ridge Fix, I only seen one instance of a 7900xtx, which are pulling as much if not more than 4090s correct? (question rephrased as 7900xtx pulls as much if not more than 4090s correct?)

Cable Mod chose to recall, and I believe discontinue the 12vhp adapter? (is this correct?) because the cost of the adapter, which was meant to try and reduce the correctly seating excuse that GN stands by (user error). But because so many 4090s ARE having an issue, they (Cable Mods) as would I stop selling a part that is causing you a negative return, due to the belief that their adapter is THE problem.

Since the recall, are there still 4090s melting connections?
With the revised 12vhp standard, with tighter manufacturing tolerances, are these now creating the broken 16 pin connector due to insertion force issue? I think most likely.

IIRC the 4070ti Super is using a cutdown 4080 die (as it should be) is this correct?
Did they make the 4080 Super at all? Is it cut down from the 4090 die or just faster memory and/or maybe more VRAM?

TLDR version, disregarding the 4080 statements above, is there a design issue with the new 12vHPWR connection? or is it in your opinion grossly over exaggerated? And user error?

Well this the point. There were very few adapters reported as melted until May of last year when the CM adapters entered circulation. That may not be solid evidence, but interesting coincidence. AND seems to have been enough in numbers for CM to issue a recall.

Make of it what you will, but look at all those reddit links BFG10k pulled out that show several 4080 connector failures with CM adapters. With 25000 of those adapters sold one could reasonable infer a hell of a lot more affected the power hungry 4090s.

Granted, I do believe the 12VHPWR is a faulty design if even allowing 1% failure of hundreds of thousands of cards sold to occur. But the way some arguments are presented in this thread is like watch out, any 40 series cards that has it is highly prone to disaster regardless of the power draw of the card.

The bad tolerances for the male and female connectors causing people to have to manhandle the connector in, seems to cause a relatively high number of broken off connectors. This would impact any 12VHPWR-equipped card equally, since it doesn't depend on the power draw.

Perhaps they tightened up the tolerances with the 12V-2x6 connectors and adapters, but Nvidia and the AIBs aren't particularly transparent about these things.

I believe the point of this thread is to bring awareness of the problem and hold those accountable for using the design. CableMod is the only company I am aware of that has stood up for its customers and done something about it. Not NVidia, nor MSI, ASUS, Gigabyte, etc for selling products that are unsafe. The fact that the cable has already been altered, and still doesn't seem to work all that well, is only more evidence that these other companies should be held accountable. Since NVidia is the company requiring this connector, they should be the ones "on trial". I commend CableMod for doing the right thing. But there were cards before the CM adapters. Gamer's Nexus didn't use a CM adapter during their testing.

If the connector is the problem, any product using that connector will also be a problem.

Possible explanation why the ground pins often don't melt: the connector sends less current back to the PSU than it takes, forcing the difference through the motherboard EPS/ATX connectors instead. This can potentially affect audio and USB signals.

Is that "healthy" for the motherboard?

50 mating cycles folks. Don't be mating your GPU connectors more than that!

While the original pins were long gone, Northwest Repair was able to cut off the same pins from a donor board and attach them to the 4090 using epoxy and solder.

Sad that an expensive and otherwise fine card suffered due to Mr. Black Jacket's greed. Don't think that card will be able to draw too much power without that solder melting so the owner will need to power limit it.

While I don't doubt Leather Jacket Man's greed, this is probably better described as hubris. And since it has gone on for so long now, there is a certainly cult-like stubbornness at play.

Then again, as someone who was badly burned by Nvidia's infamous solder defects "bumbgate", despite all the premier brand this and premier brand that, Nvidia are not a company who stands by their products. And even in the bumbgate 8400/8600/8800/nForce days, I always got the impression that they only value serial upgraders so by those millions parts went bad, as far Nvdia were concerned they should have been upgraded from already!

Yeah their business model seems to be obsoleting their previous products.

It's like some cold hearted mom who pops out a baby, nourishes it a bit and then drops it off somewhere, ready to get knocked up again!

That's just one shop! I guess a lot of these users fall in love with their defective cards so much that they can't stand the thought of RMA'ing them and then receiving someone else's repaired card. Who knows what body parts that card may have come into contact with! No self respecting filthy rich gamer wants to touch someone else's USED card!

"Don't worry, baby! I'll get you fixed and you will be back with me soon!" and then gives it a long creepy kiss before packing it to be sent for repairs to the repair shop. A kiss that would make a grown woman blush!

Video here:


200 melts / month = 6.6 / day which is higher than 25 / week = 3.5 / day we had before. Yet some people in this thread were trying to tell us "the amount has reduced to almost nothing because it was all Cablemod's fault", LMAO.

When he goes through the box of connectors you can see plenty of non-cable mod examples in it.

He actually answered this a while ago, most of the repairs he does have been denied warranty.

It's typical for workstation cards. The problem is EPS 8-pin is "only" 300W so they'd still need two of them for the 4090

Hmmm, I wonder what possible reason NV had to do this on their professional cards?
Obviously to avoid being sued by a company if a card or the entire system on their premises goes up in smoke/flames

But I would really like to see them tempt their fate. Maybe the RTX Ada 6000 has the flame-friendly connector?

EDIT: https://www.nvidia.com/content/dam/...roviz-print-rtx6000-datasheet-web-2504660.pdf


Interesting. It seems to be using a single CEM5 connector which does look like the 12VHPWR connector. Maybe this one has a saner design?
