Nvidia’s RTX 4090 might have an issue its cable melting, at the very least in line with a few experiences from consumers, points which Group Inexperienced is at present investigating.

As Tom’s {Hardware} (opens in new tab) flagged up, a Gigabyte RTX 4090 proprietor wrote about this downside on Reddit, and that publish was adopted by one other person who had encountered the identical worrying flaw.

Particularly, that is the adapter cable being burnt – the one supplied with the RTX 4090 to permit connection to an ATX 2.zero PSU (four x 8-pin to 16-pin) – and the primary Redditor (opens in new tab) offered photographic proof exhibiting that it’d been reasonably toasted certainly (see above).

The opposite RTX 4090 purchaser (this time with an Asus TUF Gaming OC card) then chimed in (opens in new tab): “You aren’t the one one. This occurred to me right this moment as properly, not as badly burned as yours although. I used to be having a gaming session few hours in the past, enjoying Black Desert with my dungeon social gathering. All of the sudden the display screen went black and all of the followers began spinning at 100%. Powered off the machine and after some inspection observed that the ability adapter was broken.”

Nvidia advised Tom’s {Hardware}: “We’re investigating the experiences. We’re in touch with the primary proprietor and shall be reaching out to the opposite for added data.”

Evaluation: The 35mm rule and secure seating of connectors

In the mean time these seem like the one two cases of this melting difficulty reported, as we will’t see every other complaints on Reddit (or elsewhere on-line for that matter).

So, there’s all the time the chance that these people bought actually unfortunate with their graphics playing cards by some means, or there was one thing flawed with their setup, or the way in which the cable was put in.

What most people are at present involved about is the way in which through which the adapter is put in, as this has been problematic by way of the adapter cable being very stiff and troublesome to bend spherical with a view to match it, whereas nonetheless with the ability to put the facet panel again on the PC case.

Certainly, the fear aired by many right here is that if the cable is bent spherical at a pointy angle to suit, this might pull on the pins, and the connector gained’t be correctly seated within the 4090 graphics card – and this isn’t secure, particularly with the quantity of energy chugging via these cables (450W, perhaps extra with overclocking and such). May this be the explanation for these melted adapters? We merely don’t know for certain, after all, however it looks as if the probably perpetrator at this level.

Nvidia’s investigations will likely throw extra gentle on the matter, though some folks have already criticized the design of the adapter for ATX 2.zero energy provides, and at the moment are questioning why it didn’t include a right-angled connector to keep away from bending the cable – which formally isn’t imagined to be bent any nearer than 35mm from the connector on the top. There’s a third-party 90-degree angled 16-pin connector coming, thoughts you, as you might have seen.

For now, although, what nervous RTX 4090 house owners can do is test the cable connector is firmly seated within the card, and don’t bend the cable inside 35mm of the top – depart loads of room. (Simpler stated than executed with many PC circumstances, although, until you’re going to go away the facet panel off, which is much from preferrred for plenty of causes like mud, potential for injury to the {hardware} innards, and a noisier PC when all these followers kick in).

Do notice that this potential cable melting difficulty shouldn’t have an effect on people who’ve a brand new ATX 3.zero PSU, which might simply use the 16-pin cable to hook as much as the RTX 4090 without having for any adapter. At the very least in concept these PSUs gained’t have any issues, anyway.

Let’s hope Nvidia clears this matter up, and confirms what occurred in these two circumstances, sooner reasonably than later, so we will know what’s up for certain.
