Nvidia has given us some sort of update on the cable melting controversy that has hit some owners of the new flagship RTX 4090 graphics card – though no doubt this isn’t the news hit by the issue.
For the uninitiated, here’s the well-documented problem with the included ’12VHPWR’ adapter that allows the RTX 4090’s 16-pin connector to be connected to ATX 2.0 power supplies (as opposed to brand new ATX 3.0 models – we’ll explain more about all this here).
So, what’s Team Green’s big update? Nvidia told KitGuru (opens in new tab)“We are continuing to investigate the reports, but we don’t have any further details to share yet. Nvidia and our partners are committed to supporting our customers and ensuring an accelerated RMA process for them.”
Nvidia came out early to say it would be investigating this issue, as you’d hope, so that update is just to let us know that this investigation process continues, and there’s nothing else to say just yet.
Analysis: theories galore are still buzzing
It’s disappointing to get what’s basically a “non-update” kind of thing from Nvidia. Obviously it’s a complex issue to tackle, but we hope it won’t be too long before we hear something concrete about what Team Green thinks is going on here.
The problem is that the longer we don’t get an official answer, the more other theories (some quite disturbing) floating around about what could be causing these melting adapter cable incidents (including allegations of under-specified 150V cables, as Tom’s hardware (opens in new tab)who saw this update points out).
However, the leading theory seems to be that any melting adapter or cable issues are wrapped up in the adapter not sitting properly in the port on the GPU itself. This was an idea that was suggested early on, and it makes sense – the problem is that if a proper and complete connection is not made between connector and port, it can be dangerous (particularly because of the hefty amount of power being consumed by the RTX 4090).
What doesn’t help is that the installation of the adapter can be heavy in some scenarios as users have to bend the cable sharply to fit it against the side panel of their case due to the gigantic size of the RTX 4090. something you should absolutely avoid, although, as noted, we still don’t have definitive proof of the cause here.
Hopefully Nvidia will have a more enlightening update soon enough, as this is certainly one of the most annoying situations to hit a new graphics card in recent memory.
