let me introduce you to the 295X2 a 500W Card with two 8 Pins... and it ran just fine.
the problem is this trash 12 Pin connector. it's flimsy and has barely any structural integrity (wide and slim).

the current isn't a problem either. a single 8 Pin "can" do 25 to ~30 Amps. (a good one with solid pins = 350W)

"AMD, however, has chosen to trump those specifications and cites a minimum of 28A (=336 W) for each connector, which brings the total to around 750 W."

I'm reading your typical M.O. here, there is never a problem for most users but eventually, at the end, we always conclude there was definitely something going on there. Remember crypto? And I can think of a few other examples. You're like a living 'this is fine' meme by now.
No, I just like evidence before panic, and I defer to experts before hysteria. I don't know where you got the rest, but admiting when I am wrong is a strength, not a weakness.

Space Invaders last gen were also quite true.
Yes, and I admitted such, given I was a victim and had to RMA a card. You really need to do better homework.

EVGA FTW's burning memory to a crisp?
Never commented on this, let alone disputed it. If I said anything, I probably said something along the lines of there was an issue but their customer support was what sold me on them from my past experiences, IIRC.

Half your "trend" of my disputes of real issues is based on things I didn't even say, or worse, I was personally affected by. If that isn't a good analogy for this thread, I don't know what is.

You're basically left with "you supported crypto and were wrong" which isn't much of anything, really. It shows ability to realize ones mistakes, if anything.

Same. I want to see this investigated by Nvidia, trusted tech publications (for example GN) and perhaps some PSU manufacturers, rather than armchair experts, that lets face it, a certain proportion of just thrive on negativity.

In the meantime be patient, and if you have a 4090 and this adapter, take reasonable precautions to minimise risk in the meantime, options like;

Ensuring the cable is perfectly inserted and is not bent in the first 35mm minimum, and the weight of the adapter doesn't sag the connection point
Routinely checking the connection to ensure the first option I list was still in effect
Procuring a first party 12VHPWR cable from your PSU manufacturer
Procuring the cable mod adapter
Perhaps power limiting the card in the meantime

If it was me, I'd do step 1 immediately, followed by ordering the 12VHPWR cable, and I'd probably power limit in the meantime and not think too hard about it.

And in short order he was proven to be wrong.
Has he? You can google burnt 8pins too you know.

Finally more testing:

Unfortunately test was done without that infamous adapter that melted, but anyway, card seems to be fine under Furmark. At least in that test, bent connector basically showed no big difference. But yeah, it's a 12VHWRP native power supply too.

Here's another source of information:
https://www.reddit.com/r/nvidia/comments/ycwr1y
Much less legitimate and yeah, power usage was most likely measured via software, which is not terribly accurate, anyway, test was done with that adapter and during Superposition run, cable averaged at around 50C. Not bad, but as far as I know Superposition is "lighter" on power consumption of card. Anyway, nothing alarming happened during stress test, so that's something.
So looking like a storm in a teacup thusfar. How... underwhelming... and expected.

In addition to my earlier post. Here are some pictures of how I have my adapter bent.

Also about connecting psu to none atx 3.0 standard like my own. Don't connect it with only two 8 pins that has a doublet. Meaning 2 x 8 pins on 1 cables. That means you will be pulling 300 watt from 1 cable designed for 150 watt at max. That risk overloaded cables and the rails in the psu it self. Psu goes puff at worst case scenario. All ways connect with 3 or 4 separate cables for each 8 pin to depending on what card you have. I'm sure most people on TPU knows that. But yet again some might not think about it and that could potentially risk overload psu power rails. 4090 can definitely pull at least 550 watt at peak. I have seen my own card do it with max power target and overclock. But never very close to the 600 watt limit. But that is stil enough to pull way more than 150 watt per cable if only 2 are connected.

Here are my pictures. As you can see it litterly tough sidedoor window. I'm trying to avoid as little bent on adapter as possible.

Honestly? What a mess, that. No offense. But this is supposed to be 'the way'... This reminds me of non modular PSU cable mess, except now you need the whole bunch just to connect a single GPU.

Wow. Just wow.

the main problem here is 12 volts.. too many amps are required at 12 volts to power the current breed of high power graphics cards.. not an easy problems to solve..

trog
But there is a competitor reducing the 'problem' to a non issue by simply using tried and tested connectors/cables...

Nvidia pushed this too early, that's the long and short of it. Its similar to what they pulled with removing DVI. Its an Apple approach, trying to drag the market away from an old principle to create something new. Its also the same thing as their RT push timing - they are the only party trying to conjure up support, and the market is slow to adjust, understandably, or partners turn away (EVGA) because they keep escalating to more silly moves, footing a higher (development) bill to them and also to end users for getting additional hardware.

Let's not move this problem away from the company who caused it and then fails to provide adequate support for their own push forward. They should have damn well instructed or even demanded industry partners to provide enough tolerance on cabling. Its not uncommon, especially not to Nvidia who has a very tight leash on its partners - or perhaps, 'had', it almost looks like their GPP move backfired a bit.

No, I just like evidence before panic, and I defer to experts before hysteria. I don't know where you got the rest, but admiting when I am wrong is a strength, not a weakness.

There is evidence. And I agree, I also like it before panic, but I don't think anyone's panicking. We're just enjoying the show here. Greed and relentless commercial progress turned into a shitshow, that is the long and short of this and more recent hardware releases. Its almost a given by the way with every top end GPU release - high wattage simply requires a much higher quality environment in every way...

Maybe my mind is foggy on the past with these events. Sorry 'bout that.

You are right it is a mess with those 4 8 pins. It's ugly. I am just waiting for alternative adapters comming for sale and get this eyesore and firehazaard out of my pc asap.

Thank god mining is dead mostly, imagine if a 4090 made like 300$ per month from eth like the 3090 did in 2020 (the logic being oh well i'll get the scalper premium back in a month), people would buy them, start mining and i'm sure there's is/was a % of people that didn't bother undervolting to find that "max hashrate/lowest power consumption while being stable" sweet spot and just go to bed or leave the room where the rig is :eek:

Imo, PSU manufacturers are going to have to make the cable improvements. Hopefully sooner rather than later. Corsair has had theirs on the market for quite a while. Apparently bequiet as well. I would like to see how theirs compare to Nvidia's. I'm sure it won't be long (tomorrow) before some enthusiastic reviewer does a head to head of the available offerings. That's the obvious next step.
If there continues to be enough noise made online about these cables failing ngreedia may implement a recall or trade in but its unlikely. As out of character as it was, they did cancel the 4080 12gb afterall the online noise it created. Most likely they will leave the AIBs to absorb any RMAs and try to blame user error on the failures. They haven't released enough FEs for it to effect their OWN bottom line.

I was only half joking about the cheap Amazon cables creating a bigger problem once the pretty, colored knock offs hit. We are all well aware that the larger part of humanity doesn't pay much attention to specs or manuals but they absolutely have to match psu cables. We just might hear stories about GPUs smoking away in a few days or weeks.

Unlike 8pin/6pin cables that we've been using like, forever, the 12VHPWR connector and slimmer cable seem to be designed with aesthetics in mind, unlike 6/8pin co0nnectors and cables which were overbuilt. How many of us have bent and twisted these cable for cable management within our cases, and not in the least bit concern that they would overheat and burn, sure there may be outlier cases through the years, but these were prolly attributed to bad PSU or faulty cables perhaps.

These 12VHPWR cable and connectors are a different breed, they seem underbuilt, that is they're not as robust as they should be, and are more likely to fail. I wonder whose idea it was to run so much power through thinner cables/wires in the first place. I dunno about you guys, but when I build a system, and built it well, I'd appreciate that the cables/connectors in my system not fail on me (through no fault of my own), and fail catastrophically in such a manner.

Unless this issue can be resolved, I don't see how nVidia can, in good conscience, release its other RTX 4000 series cards with the 12VHPWR cable and connector. Cablemod right angled connector is a good start, but imo, nVidia should have supplied such a connector with every RTX 4000 series card in the first place.

There is nothing wrong with the normal 8 pin connectors. The only reason for the 12 pin is PCB space. There is nothing "safer" about the 12 pin.
I don't doubt after AMD not adopting this stupid connector on their 7 series GPUs more will follow suit shunning it

And they could have use that as an excuse to charge $100 more for the card in the process ...

That means you will be pulling 300 watt from 1 cable designed for 150 watt at max. That risk overloaded cables and the rails in the psu it self. Psu goes puff at worst case scenario. All ways connect with 3 or 4 separate cables for each 8 pin to depending on what card you have. I'm sure most people on TPU knows that. But yet again some might not think about it and that could potentially risk overload psu power rails. 4090 can definitely pull at least 550 watt at peak. I have seen my own card do it with max power target and overclock. But never very close to the 600 watt limit. But that is stil enough to pull way more than 150 watt per cable if only 2 are connected.

Here are my pictures. As you can see it litterly tough sidedoor window. I'm trying to avoid as little bent on adapter as possible.

And AIB cards are going to be taller( a lot of ), OMG.

Cost cutting should of been a right\left angle connector, or a lack of tasting by people who don't run there hardware in a case.

So looking like a storm in a teacup thusfar. How... underwhelming... and expected.
I'm not sure. Well, perhaps underwhelming, but so far there are three main problems:
1) nVidia's adapters suck, because they are flimsy and metal pins can't handle typical insertion forces of typical user.
2) nVidia made adapter to the spec, which means that spec won't change or won't change fast enough, therefore shitty adapter and too thin pins will be commonplace, granted that this new connector would gain traction (because it may not).
3) PCI-SIG found some power supply cables overheating, which is concerning, but so far no examples in real world have been found.
3.5) PCI-SIG is powerless in enforcing standards.

My own personal experience is that some standards like Molex have been crap, I have burned Molex connector by accident too, because pins in plug have too much play and are hard to plug into and you can easily bend pins inside of connector too. BTW it was Fractal Define R4 case's fan controller that burned cable. Thankfully it was small accident and no significant damage was done. The scariest burning accident I had was old (around 15-17 year old) hard drive exploding some chip on it during boot up. It was loud and scared me, also stank really badly and very long.

There is evidence.
Well yeah, but not that it exceeds the norm for a high wattage connector. At least not yet.

One thing we can all agree on I think is wattages are getting way too high...

PCI-SIG found some power supply cables overheating, which is concerning, but so far no examples in real world have been found.
That article was again, a complete WCCFtech fabrication. Otherwise yeah, it seems Q&A is the main concern here.

Megathread on Reddit has been started to investigate this issue and gather more data:

Interesting
This is a good way to go about this, good job finding it. Community research is the best we can manage right now. Do remember that despite individual incidents, many many such adapters are sold, so I am curious how common this really is. It could be anything at this point. We badly need stats. Still, verifiable community polling is a good place to start.

PCI-SIG is powerless in enforcing standards.
This is pretty much true, btw. They just write the standard. Anyone can make a china copy of it. It's probably up to nvidia or similar to enforce stricter connector regulations on the AIB makers themselves.

Maybe my mind is foggy on the past with these events. Sorry 'bout that.
It's all good. With the crypto mistake I can see me getting blended in with some other users. Just wanted to set the record straight.

The problem is simply with the new graphics cards that use the 12/16-pin connector being too big for normal cases, cables have to be bent to put side panel on and bent they are too close at the connector, thus causing poor contact surface between connector and graphics card. With high currents per pin (DC), that causes heat and thawing of plastic, simply put. :)
October 31st '22 there will be available first 90° cable adaptors with such connector or so I'm told...

Has he? You can google burnt 8pins too you know.

I’m talking about this, not in relation to 8pins.
I know stuff gets memory holed fast these days, but it’s been like a couple weeks.

I promise you someone burned 8pins in a couple of weeks too.
