Been seeing all over the internet from Reddit to Twitter, and even on nvidia's discord of some 4090 owners having their 12pins burn out. So if you are using that infernal 3x pcie adapter be careful and keep a watchful eye. If you happen to have a Corsair type 4 psu I highly suggest you buy one, sadly the cable they have is not available yet or sold out with no ETA Just asked about it...

Also there is probably going to be a long wait from cablemod but that is an option for corsairs's type 4 psu's if you want a 90 degree cable that is more than just plain black.

Link to twitter for the first picture believe Jonny guru brought this up on the load with the 3x pcie connector to 12pin as well on discord.

Yeah, there is still only 12 pins, no matter what pci-sig pushes. It’s still two 6 pins using 16awg wires with two grounds for signal. PCI sign wants the “new spec” pushed because of underpowered PSU’s. It’s not magic. 600w across 12 cables is still 600w across 12 cables no matter how many 8 pins are connected to the other end.

I'd say the sleeved cable adapters cause more of a problem than you would have with just the loose wires.

I'm a bit disappointed Amphenol thinks those dinky contacts are good for 9.5A each especially in a row.

Does FE cards have a power problem or AIBs only?
 

So far I have not seen anyone post about a founders or MSI. Mostly has been Gigabyte and ASUS.

I hope it's just freak chance its the internet and well globally even nationally there are going to be those that have problems... yet more have been popping up today. Just something for everyone to keep an eye on.

I would think it would affect all brands watching Jay2Cent video about how they put the cable connector on the FE and all board partners as NVIDIA has made the cable hard to cable manage. I can’t say this is what caused them to burn out or anything but he did point out that people will be pulling on the adapter trying to bend it in a way the cable wouldn’t want to bend to make a clean looking system. He gave NVIDIA his ideas of how they could possibly look at improving the card to be more friendly for gamers and also gave tips to not put as much stress on the adapter.

Tonight I saw he posted a video where people have been claiming he was right at launch about the cable looking to be a problem.

Yeah so how are you supposed to fit that in any remotely normal case?  That sticks out more than an AOI hose on a Kingpin.

The adaptor cables are already very heavy and cumbersome for such a low-pitch connector with a short mating interface with stamped sockets. Any pull on that connection is going to cause issues. The same could be said for the 8-pin style, which is why there were incidents with those too, but we generally didn't hang so much weight off a single one of those connectors and they didn't individually have to carry as much current. The way these companies rate the current of their connectors, it's always assuming all conditions are perfect, which in use they almost never are. There are plenty of better options out there with better securing methods that would have avoided this whole thing.
 
A couple examples I found quickly (quick for me, an EE, who picks connectors for products all the time so I have a virtual catalogue in my brain...which is handy but feels like I'd rather remember how to do math than retain this information lol):
 
1. Samtec power blades with metal latches on the sides:
 They could get these in 8-10 pin versions that are right-angle to the PCB (which is how the current connectors are), which use cables that default at 16AWG. I'd personally be fine with having a separate smaller connector that does the sense lines if we need to entertain adaptors and all that jazz. These are 18A per pin. If you split that across the 12V and GND pins, you can drive 72A at 12V = 864W on one connector. You need more for a HOF or KP style card? use two connectors. The side latches keep the connector from wiggling and twisting and the board connector has solder tabs that keep it from twisting on the board.
 
2. Harwin 3mm pitch connectors.
These don't come in R/A connectors, but they're actually pretty small and come in 10-pin versions, 10A/pin. So if 5 12V and 5 GND gives you 50A, at 12V = 600W. They also have jack-screws so the cable connector actually screws to that one with captive screws (that don't fall out). So they could do budget cards with one connector and HOF/KP style boards with 2 connectors and still not take up much space. These are machined round pin connectors and they actually use 18AWG, so you don't even need the super cumbersome 16AWG wires.
 
3. ITT Cannon Trident Slimline (pages 18-21)
These are a little bigger because they're single-row instead of dual-row. Wouldn't really be ideal for situations where you wanted dual connectors, but you could actually do two straight ones right next to each other fairly easily, it would just mean making a clearance around the BEEFY cooler lol. Part numbers 192991-0538 (right-angle) or 192991-0354 (straight). Both 10-pin connectors, rated 500 cycles, 10A pins, again 600W rated. These have side latches and can be screwed to the PCB.
 
Anyway, this is all just conjecture and I know people in here aren't designing the cards, but I see this kind of issue and get grumpy because you can look at that connector they used for 2 minutes and know there are problems with how they're using them. This is just cost-cutting BS. Those connectors are probably 10-50 cents a piece instead of a couple bucks. On a $1600-2000 GPU, give me the $2 connector that prevents bricking the card. Those are just 3 options I know of that would have helped prevent this type of situation and there are tons of companies out there with other alternatives. I'm sure if you spend a few minutes looking through catalogues from Amphenol, ITT Cannon, Molex, TE/AMP, etc. you'll find more good options. All of which have prices that aren't too ridiculous when you consider that Nvidia's board partners will be buying them in volume. They could also probably work out a deal where Nvidia purchases them in even higher bulk quantities and then distributes them with the GPUs to keep pricing even lower.

Nice work.  Very fancy.
 
Here's a thru-hole mount 90-degree Size 25 9W4 D-sub thats rated 40A per power pin (4x) and costs $6.40 in qty 2000.

The one Kevin picked (no offense, Kevin), would be harder to split off in my opinion as you have to solder in 2-4 wires into each of those single high-current sockets. Well, generally you put the pins on the thing receiving power and the sockets on the cable providing the power...so the connector you put a picture of is the wrong gender, the one the PCB would be pins, so when I say soldering extra wires into the sockets, I mean they'd have to go into the mating connector's sockets, assuming that the board connector has the pins. I also found a couple from Harwin for example that had a similar layout. If combining wires is simple enough within the mating connector (and doesn't cause the bending lol), those can be great because the mixed signal connector allows you one frame to put the power and signal wires into, unlike the ridiculous 12VHPWR thing with the 4 side-pins...much safer. Also, your connector series is considerably better than what they picked lol. I was just saying why I didn't opt for a D-sub connector series. Nothing wrong with those though, in my opinion.

I would argue the convention on d-subs is for the chassis or CCA jack to have sockets and the plug with pins on the cable, regardless of the power direction.  But you could probably go the other way if you wanted to.   I'm bringing up the D-subs because they are a bog-standard solution to this problem - bringing power to a CCA.  Everybody makes mixed dsubs and they are used in many many places....including PCs.
 
Here's a sample 40A contact:

So 8awg wire contacts.  You could run 6x 18awg wires into each and crimp with a 10awg tool setting, which should give you two (1x 12vdc, 1x gnd) 40amp pins for two 8-pin PCIE jacks (150w+150w @ 12v -> 25A), or four 8-pin (3x 12vdc, 3x gnd each) on this one Size 25 D-Sub.  This is non-trivial to do repeatedly, so it may make more sense to run 8awg off the plug and have a splice elsewhere.
 
Unfortunately this probably costs 10x Nvidia's crappy plastic plug.

Here is how my cable is...
 

 
No issues yet.

From what I have seen on Reddit, Twitter and discord if there is going to be a problem it’s normally been at the 10-14 day mark. I hope it’s just isolated incidents.

I felt the cable & connector on the card last night when I was drawing 500+ watts from the card for 2 hours. Was just warm, but not hot to the touch.

Yeah, there is still only 12 pins, no matter what pci-sig pushes. It’s still two 6 pins using 16awg wires with two grounds for signal. PCI sign wants the “new spec” pushed because of underpowered PSU’s. It’s not magic. 600w across 12 cables is still 600w across 12 cables no matter how many 8 pins are connected to the other end.

you forgot one key thing
 
this is 2022 and 2+2 = 5 = 4

Here is someone showing kind of what’s going on when things heat up.
https://twitter.com/sirsq...us/1584988628027310081

I'll be installing my ASUS TUF RTX4090 OC tomorrow (gotta swap PSU's between my builds as I'm short 1 PCIE connector on the Corsair HX1200i, non-issue for my AX1200i) and I already have a native CableMod ModMesh Pro 12VHPWR to 4 x PCIE (Corsair Type 4) cable. I suppose I'll find out how hard it is to follow the guidelines laid out by CableMod when I give it a try.

https://www.youtube.com/watch?v=HAZWwwHScaQ&ab_channel=JayzTwoCents This what he saying about it kind make sense but who knows could some cables are factory defective is not unheard off.

NVIDIA has denounced this. I'd like to point out that NVIDIA is in contact with every person affected by this.
