This is a fiasco, Nvidia. GeForce RTX 4090 continue to melt and burn, and this is a pattern
After the first case of a GeForce RTX 4090 fire was described, there were suggestions that this was not an accident, and everything would not be limited to this. Indeed, other incidents followed. And in all cases, the same weak point is the connector for connecting additional power and / or the branded adapter cable included in the package.

How many of those pins are actually +12V. Just like the PCIe 8 pin connector, there are only 3 +12V and the rest are GND and sensing connectors.

I had once of those dual Radeon 6990 GPUs which was basically 2 of the Radeon 6970 and it only had 2 * 8 pin connectors. That beast can pull 600 Watts if you overclocked it, I think it used like 450Watts in some high intensity games or mining. I assumed the connectors would burn but they never did.

My guess is that its not the GPU but the adapter which is causing the melting. They need to use better female pins.

This is pretty crazy. It is widespread or just from one brand? This seems a little unbelievable for a company as established as Nvidia. Especially when they know that heat is a big issue with this product. I haven’t seen a whole lot of complaints about these yet, but I also didn’t know they were getting into people’s hands already. What is your advice? Holding off on purchasing for now?

This is probably one of the reasons why evga noped out  ::) Also cable mod is coming out with a right angle adapter which should help with a lot of the issues, but we'll see.

https://store.cablemod.com/cablemod-12vhpwr-right-angle-adapter/

I’ve melted 6 and 8 pin pcie due to poor cable construction/pins while mining.  Countless breakout boards melting also.  Eventually settled with no more than 75w per 8 pin cable and many more quality cables to stop it.  Sellers literally sell non compliant cables on the daily.  Then EVGA started giving away a right angle adapter with high spec 1080-1080ti’s due to melting twin 8 pin plugs.  They added capacitors inside this adapter to help with surge currents/stress on the pins.  I got lucky due to having smoke detectors hovering over all miners.  Others not so lucky.

Fast forward to this shit show with stupid tdp’s and custom connectors.  People are literally bending the cables at the connectors 90 degrees to stuff it into cases.  Some people have broken their glass sides due to the pressures exerted on the cables/glass.  People flocking to these 4000’s due to the long drought will be granted some smoking  GPU performance, literally.  The pins cannot sustain such punishment and needs to change.  The whole pcie power standard need rethought IMO.  The person who doubled the 6 to 8 pin power maximum by adding 2 additional ground wires needs beaten.  Now this 4000 series stuff being the wave of the future, no thanks.

450W TDP @ 12V is 37.5A RMS, not accounting for peaks/surges.  The whole multiple wire plug, not equal length wires and poor current sharing, low insertion force pins, is not going to cut it at these levels.  EVGA is the best IMO, and didn’t get there by being dumb.  They clearly made the right choice for a multitude of reasons.

My opinion is that this connector initially looks like shit. It is better to use several standard 8 pin connectors. Then the owners of power supplies will not need additional adapters and there will be fewer problems. I hope that AMD will not use such a connector.

Except for the 4 tiny sensing pins it looks just like the old 8 pin connectors but with more pins. The problem is the poorly designed and built
adapter. It's the shitty riser issue all over again but at much higher power levels. It's Nvidia's fault for poor quality control of their outsourced adapter.

Edit: The right angle connector may solve the issue simply by being better built in addition to avoiding the stress of bending.

it is ridiculous to use that cable on a card with that wattage, I can understand on an 80 series but on a 90 that has out-of-standard consumption they should have inserted at least 2 to avoid such risks. A cable operating under optimum conditions at 95% load that can handle the slightest change (whether it's a badly ventilated case or a PSU that drops the voltage 0.1 from normal) can lead to disastrous results. without considering that by doing so you limit customization, preventing you from buying third-party cables to change the aesthetics. A cinesata would burn the pc in the first session.

AMD already confirmed they are using 8 pins.  There is also a rumor that they are adding their stacked 3d cache on the 7950xt.

https://www.techpowerup.com/300252/radeon-rx-7000-series-wont-use-16-pin-12vhpwr-amd-confirms

I have 4x evga 3090ti units.

they feed 3 8pin pcies to that cable.

the tdp on the 3090ti is 350 watts

i run them at 325 watts 24/7/365 dual mining zil and etc.

I cant imagine pushing 450 watts to that cable adapter provided.

even 3080ti suprim x uses 3x 8pin pcie, that 4090 uses 12 pin vs 24 pin (3 x 8pin), x2 amount of wires for a lower wattage cards.

worse case scenario is 4xxx series get another refresh before we get to the next gen architecture of GPUs LOL.

Well at least since the connector adapter  melts the PSU is saved pretty much. Because the GPU will be RMAd.

I can’t imagine warranty from another manufacture covering the PSU if it was a faulty GPU which caused it. Would Nvidia warranty also cover the PSU or are you out of luck ? Never had this happen before to know.

The service center will not accept melted connectors on the power supply under warranty and will write an act where it will be denied repair or replacement. In most cases, this is the user's fault. That's why I don't buy top graphics cards, and I read reviews carefully before buying.

It's not clear how much OC was involved in these cases so it may have been more but the new connector is supposed to handle up to 600W.

PSU damage could be covered a number of ways. The AIB partners may cover PSU damage to please their customers then try to recover the costs
from Nvidia. End users may file a class action with Nvidia and/or the AIBs. It's unlikely the PSU providers will cover it themselves.

EVGA must be relieved they dumped Nvidia and have avoided this problem.

The adapter fully analyzed by Igor. You can stop now all speculations.

Edit: Nvidia is briefing board partners now: https://www.igorslab.de/en/adapter-gate-nvidia-briefs-today-early-all-board-partners-and-makes-damage-an-absolute-chief-issue/

I have seen a couple of friends using such adapters and I am always against,I always use 8 Pin PCIE connectors from really good brands in power supply like Corsair or Evga and I rarely use any other brand.I have not had a 3090 myself but several of my friends have and they never had any problems by running them with these standard 8 PCIE connectors from good branded power supplies.
I doubt Nvidia has made any lousy implementation,they are not well known for them,on the contrary they are well known for perfect implementations in most cards.

Well after reading this I am very grateful that I only feed my four 3090ti's 325 watts each on that adapter.

What could go wrong when you put 600watts in these tiny 12pin.so will see 24pins on rtx5090 with 900watts tdp  ;D

Your right, no need to speculate that Nvidia has provided total shit wiring design for their AIB’s to use…. Glad we only listen to such experts instead of us plebs here using common sense and experience.

“ The overall build quality of the included adapter for the GeForce RTX 4090, which is distributed by NVIDIA itself, is extremely poor and the internal construction should never have been approved like this. ”

Even on inexpensive, budget power supplies, I had no problems with the power supply, although I also love Corsair, Cougar and Evga.
Nvidia chose a bad supplier for the adapters, but this does not relieve the company of responsibility. They were obliged to check the quality of the adapters.

well to be nice they can handle 325 watts if not bent.

far cry from 600 rating. but mine are good so far no bends and 325 watts running since august.

It gets betterworse, a PSU ATX3 connector has melted with no adapter. I'm not familiar with the PSU brand, maybe cheap.

AMD Radeon 7900 pictured
The pictures were posted by @9550pro who claims to have them from a closed QQ chat group.

The card is clearly a prototype, with a red board design and voltage contact points in some places. What is clear though is that this design matches what AMD has been teasing in late August with three red stripes on the heatsink.

The PSU was an MSI MPG A1000G, not the best psu available, but not cheap too

Here's more about: https://www.tomshardware.com/reviews/msi-mpg-a1000g-power-supply-review

1000w of power, certified by Cybenetics with 80 plus gold, only japanese capacitors and 10years warranty.
Definitely it's not a PSU to have a melted cable, it's the perfect pair to be used with a 4090 in my opinion, and this is a reason to be worried

I'm thinking here, can you imagine the number of possible accidents and melted cables with 4090 if mining was good like last year?

maybe less since smart miners under volt and would likley not have to push more than 375 watts for max hashrate.

Oh yes, it makes sense  :D
But can you imagine a rig with 4x 4090 running, suddenly crashes and all 4 cards goes to default settings for several hours  :o
Hehehe

It happened with me a few times

Yeah that sounds like a fire waiting to happen for sure.

nvidia had to do many more tests before launching the 4090 on the market, that cable adapter provided for the additional power is not up to the task so there will always be a risk of fire

they could have done two that were feed by two eight pin connectors.

so four into two which would have likely been better.

A brand new connector that already needs to be doubled up on the first GPU to use it would not be acceptable.
The ATX3 connector is supposed to handle 600W so what gives? Is it poor design or can an OCed 4090 draw more, much more to cause melting.

its pretty simple shrinking the 3 eight pin connectors down to the far smaller connector is next to impossible.

and the tdp of the card is 450

i can pull 525 watts on some of my evga 3090s they rate at 350 (need to check that)

but that is 50% higher than the tdp.

https://www.techpowerup.com/gpu-specs/evga-rtx-3090-ftw3-ultra.b8093

under stupid testing feeding it with 3 eight pin cables and an evga 1600 platinum psu I can spike my meter an extra 520-530 watts. i use a taichi mobo and an threadripper. various msi testers can do it.

it usually will blue-screen in under ten minutes when i do it

based on that the 4090 with a tdp could pull 450 x 1.5 = 675 and boom death to the plug or jack.

Going from memory of reading a test report, the 4090 has lots of OC headroom but not much performance gain.
if a 3090 can pull 1.5 x TDP maybe the 4090 can pull even more.

No need to analyze adapters anymore…. Maybe someone should analyze how I2R losses work and how they increase as resistance/temperatures rise.  Loose gets hot, hot gets more loose, a self-fulfilling prophecy to a fire.  I know, we need to invent atx 4.0 because 3.0 doesn’t work, seems legit.  12V rails RIP.

It is the board design, adding extra sockets means "flat and wide" copper on the board, maybe there is a trade off in which they choose less socket.

Maybe they are forcing people to not mine on it, just like what those thermal pad issues on the gddr6x's, this power socket issue is just a lot worse case than thermal pads where you can change it easily..more like a hardware LHR, you mine you burn LOLOLOL

It was so dumb that you can't say that's possible for a big tech corporation, if you look at them the same way as big pharma, it is actually a genius move..an evil genius hehe.

Agree completely. BTW that's I²R to emphasize it's not linear. ;)

Peaceful are those days where you can use thunderbolt or Crossfire to run Two graphic cards  ;D with ease, nowadays they want to combine the power of two high end GPU in one box, of course, there will be some bad news  ;D. Maybe AMD will best Nvidia this time around only time will tell.

and it may be that 3090 is the card that has real staying power as a miner.

the 1080ti was still turning a profit up to sept 2022.

my 1080ti hybrids always made some money even in  late 2018 and 2019.

they ran from dec 2017 to sept 2022. still work.

NVIDIA has problems with video card sales and their marketers don't know what to do to increase video card sales.

NVIDIA RTX 4080 12GB now to be called RTX 4070 Ti
As expected, NVIDIA is changing the name of the ‘unlaunched’ GPU.
https://videocardz.com/newz/nvidia-geforce-rtx-4070-ti-to-replace-canceled-rtx-4080-12gb-sku-launch-in-janaury

Of course they are going to have problems,Ethereum going to PoS killed their sales and will continue to do so until we have another coin which will substitute the Ethereum and be as good as Ethereum in mining rewards in order for them to recover their sales.That LHR bullshit that they came up with so to say that we are pleasing the gamers was just done to shut some of the gamers up but they knew very well that their main market and earnings which were huge by the way in 2021 is exactly because of mining.I don't feel sorry for them the slightest.

I feel sorry for Mr. V.B. he has a long list of enemies by now.

I don't feel sorry for him either,I am waiting not that patiently to see his so famous ETH that has got to green energy PoS fail miserably like many of us have predicted here.Meanwhile as I wait I have got nothing better to do than mine some ETHW and hope for the best for the upcoming crypto bull run,many don't expect it anytime soon but I think it will surprise us all how soon it will be here.

I like that some bull runs deep in your belief.

the POS shitstorms with centralized exchange scam[scam token/scam trading sauce/scam tokens/scam hack] and SEC/governments attacks might bring life and change tide for the old good decentralized mining for the next bull run.

I wonder how come the ETH who moved to PoS is not failing even bigger and that is not going to levels like 150-200 dollars for a coin,I believe the reason is because it is well known in a vast majority of people and also people who mined it and are holding a considerable amount of it do not want it to fail but my advice to them is sell the ETH now while is still over 1000 dollars for a coin otherwise you risk to lose a lot of money because this coin has absolutely no  future and is in the hand of a gang (a bunch of people who can do whatever they like to it).

Hopefully people holding ETH release now that they are in the same situation as holding Bitcoin or other crypto on a centralized exchange because as I said a bunch of people is managing it.

ETH is going to fail. It is a dead man walking. The only thing saving it is the sating is frozen and zero profit come out of the staked coins at the moment.

Eth will likely hold price as the big boys slowly sell it off. Most won't realize that scam until the stake coins are unlocked in late 2023 or even 2024.

Are you saying that unstaking is impossible?
According to statistics, there are not very many coins in staking, it is 12 percent. If there were 50% of the coins in staking, then I would be afraid of massive sales after unstaking.

A staked coin is frozen at the moment. So it is stuck. I suppose If I had a fullly staked node I could sell it off.

I have under 1 coin staked at coinbase. For all intents and purposes it cant by unlocked.

I would not sell my entire coinbase acccount to someone. Even if it only had 300 usd worth of eth. Selling the account would mean the buyer gets my kyc.

I have a simple question how long before eth unlocks the staked earnings. as of today noone knows that answer. maybe 2023 maybe 2024 .

coinbase doesn't give other tokens in return like Lido Staked Ether?
I was not interested in staking due to the fact that mining gives much more profit and there is no risk of losing money on the exchange.
Can you spend your staking profits?

Nope. I did 300 usd at the time eth was 1500 a coin. It gets 4%  so since eth dropped in price it is worth well under $300 even with the 4% interest. It will be frozen for at least 2023. It is well under 1% of my mining gear.

the
LTC/DOGE
BTC
Grin
KDA
Gpu
gear ain't worth much as it was. It is paid off and still turns a profit just not much of one.

We were over 30k a month we are well under 10k.

and it is a 4 way split.
