New fiasco Nvidia GeForce RTX 4090

[philipma1957]

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.

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 
But can you imagine a rig with 4x 4090 running, suddenly crashes and all 4 cards goes to default settings for several hours 
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  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  . 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.

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.
