Nvidia is looking into reported issues with RTX 4090 GPU melting cable

Description:
Team Green is investigating what happened in a couple of very worrying
reports from RTX 4090 owners.

FULL STORY ======================================================================

Nvidias RTX 4090 could have a problem its cable melting, at least according to a couple of reports from buyers, issues which Team Green is currently investigating.

As Toms Hardware flagged up, a Gigabyte RTX 4090 owner wrote about this problem on Reddit, and that post was followed by another user who had encountered the same worrying flaw.

Specifically, this is the adapter cable being burnt the one provided with
the RTX 4090 to allow connection to an ATX 2.0 PSU (4 x 8-pin to 16-pin) and the first Redditor provided photographic evidence showing that itd been
rather toasted indeed (see above).

The other RTX 4090 buyer (this time with an Asus TUF Gaming OC card) then chimed in : You arent the only one. This happened to me today as well, not as badly burned as yours though. I was having a gaming session few hours ago, playing Black Desert with my dungeon party. All the sudden the screen went black and all the fans started spinning at 100%. Powered off the machine and after some inspection noticed that the power adapter was damaged.

Nvidia told Toms Hardware: We are investigating the reports. We are in
contact with the first owner and will be reaching out to the other for additional information. Analysis: The 35mm rule and safe seating of
connectors

At the moment these appear to be the only two instances of this melting issue reported, as we cant see any other complaints on Reddit (or elsewhere online for that matter).

So, theres always the possibility that these folks got really unlucky with their graphics cards somehow, or there was something wrong with their setup, or the way the cable was installed.

What most folks are currently concerned about is the way in which the adapter is installed, as this has been problematic in terms of the adapter cable
being very stiff and troublesome to bend round in order to fit it, while
still being able to put the side panel back on the PC case.

Indeed, the worry aired by many here is that if the cable is bent round at a sharp angle to fit, this could pull on the pins, and the connector wont be properly seated in the 4090 graphics card and this isnt safe, especially
with the amount of power chugging through those cables (450W, maybe more with overclocking and such). Could this be the reason for these melted adapters?
We simply dont know for sure, of course, but it seems like the most likely culprit at this point.

Nvidias investigations will doubtless throw more light on the matter,
although some people have already criticized the design of the adapter for
ATX 2.0 power supplies , and are now questioning why it didnt come with a right-angled connector to avoid bending the cable which officially is not supposed to be bent any closer than 35mm from the connector on the end. There is a third-party 90-degree angled 16-pin connector coming , mind you, as you may have seen.

For now, though, what worried RTX 4090 owners can do is check the cable connector is firmly seated in the card, and dont bend the cable within 35mm
of the end leave plenty of room. (Easier said than done with many PC cases, though, unless youre going to leave the side panel off, which is far from ideal for a number of reasons like dust, potential for damage to the hardware innards, and a noisier PC when all those fans kick in).

Do note that this potential cable melting issue shouldnt affect folks who
have a new ATX 3.0 PSU , which can just use the 16-pin cable to hook up to
the RTX 4090 with no need for any adapter. At least in theory those PSUs wont have any problems, anyway.

Lets hope Nvidia clears this matter up, and confirms what happened in these two cases, sooner rather than later, so we can know whats up for sure.
