"You're holding bending it wrong" 3 meltdowns so far, many more to come. Did they (nVidia) only test that thing on open benches ? Or didn't test it at all?

Well, put a hard plastic cover up to where you can start bending the cable. Or a sticker indicating it on the cable. If this can happen, it is better to apply the remedy beforehand.

As i said on another post, the reported number is irrelevant as all issues start with a single report. What is import are the most likely course of action and the most significant course of action. If the most significant course of action can happen, it will at some point actually happen. If a single PC catches fire due to this cable then it might as well be all 4090s catching fire as NV will have to not only replace every cable but also conduct some serious product and reputation damage limitation.

PSU reviewer Aris Mpitziopoulos tested the thermals of the 12VHPWR connector under various conditions. I think the manufacturing quality of the connector, cable is whats ultimately important, rather than the bending. Problem is too much variance in manufacturing to ensure perfect quality in all cases and thats when bending may exacerbate the problem. [youtube=jNreBLVP6NU]

Could be a big factor, seeing it's mass production of a product for a problem that was never a problem.

No matter what's the outcome, many users will pause their purchase from now I can tell.

Exactly. Nvidia suddenly got an obsession for tiny PCBs with Ampere despite coupling that with the largest heatsink ever at that point. The connectors were never the main factor in the size of the card. Glad to see AMD isn't using this already dead 'standard'.

Matter of fact, I will neither buy one myself, recommend or sell one and for sure NOT install one anywhere as I do not want to be the one to blame ! Looking at AMD now.... bye bye Jensen

And thats an important point, it may well move culpability to the end user or builder.

I'd say considering people have only been using it a week, 3 is quite a worry. I'd also say, I have some Asus TUF models here and was surprised to see there connector at a straight angle to the PCB considering the depth of the card, as it makes it unlikely to fit in the vast majority of cases if you want the max 2cm bend radius recommended. I would have expected the connector to be angled slightly, perhaps similar to the reference 3090 cards.

This whole 4090 launch it getting more and more ridiculous. They must have known this during the development of the 3090. On the 3090 FE, the power connector was oriented vertically and at an angle. So only a very slight bend and very good to route the cable nicely. Now, you need an aftermarket cable to be a bit safer, and a cablemod 90° adapter. And about the power draw, this thing has the same amount of electrical capacity as 2x 8pin. They should have just revised the 8pin, new version with 300W spec. Change the socket slightly to prevent compatibility with the old one.

Good thing I can't afford a 4090 because the cables inside my case are all bended and twisted like spaghetti...

More and more PSU suppliers are coming up with their own ATX 3.0 power cables, so you don't have to use NVIDIA's adapter. For instance, this is Bequiet's cable for their current crop of PSU's : https://www.bequiet.com/en/accessories/3959

I was looking for precise specs. from SIG + testing+ review docs/ charts, but no access without a member account, very customer unfriendly and disappointing. Regarding G3D FLIR pic, 60°C max. load looped, is way toooo hot. Sorry, I disagree, this is NOT ACCEPTABLE. Don´t touch a 60°C connector! Is it measured inside a PC case? Looks like heat comes from pcb also, not only from bending cables? Why not a problem with 3090TI? I really "was" for a new ADA but now I am not sure anymore $1600.- / €2000 for this bad quality? No matter how many cards affected! Omg, officials should issue a purchase warning, risk of burns!

Perhaps nvidia shouldn't have pushed beyond reasonable power limitations for their new flagship.

Basically: You! - yes You! You: - Sell me this card, or - Install this card, or - Recommend me to buy this card! now - my house is in fire! (Or already burned down). And You know that it could happen! it was in every news every TECH website! I will sue You for ALL you've got!!!

3 connectors out of 4 million connectors is not a calamity. You have to factor in the possibility of junky or grossly underpowered psus being used, power surges, poor wiring in a domicile, thunderstorms etc. Then throw in Pci 3.0 psus being recommended for use and I see only a mountain being made out of a mole hill. 300 yes 3 no. * So, in the interest of being fair and honest (what a concept huh?) I have viewed an article that shows the inside portion of the plug where the wires run in to the base has small metal prongs where they are soldered to. If you bend the cord sideways enough times or go for a crazy side bend, I would imagine, you can stress fracture the outside metal pieces. Thus, disabling those wires carrying power. Then it is believed that too much power is run through the remaining wires causing excessive heat. I do not know if this is true. But how much of this is Nvidia's fault or the person that bends the crap out of a power cord?
