Nvidia has – in a way – given us an update on the fusible cable controversy that has affected some owners of the new flagship RTX 4090 graphics card – although it’s undoubtedly not the news that’s affected by the issue.
For the uninitiated, this is the well-documented issue with the included ’12VHPWR’ adapter, which allows the RTX 4090’s 16-pin connector to connect to ATX 2.0 power supplies (as opposed to brand new ATX 3.0 models – we explain more about all this one).
So what’s the big update from Team Green? Nvidia tells KitGuru: “We are further investigating the reports but have no further details to share just yet. Nvidia and our partners are committed to supporting our customers and ensuring they have an expedited RMA process.”
Nvidia came forward early to say it was investigating this issue as you would hope, so this update is just to let us know that that investigative process is ongoing and there’s nothing else to say just yet.
Analysis: Theories still abound
It’s disappointing to get some sort of “non-update” from Nvidia. Obviously it’s a complex subject, 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 of them quite worrying) have been floating around as to what could be the root cause of these melting adapter cord incidents (including allegations of under-specs). 150V cable, like Tom’s hardwarewho discovered this update points this out).
However, the prevailing theory seems to be that any melting adapter or cable issues are related to the adapter not seating properly in its socket on the GPU itself. This was an idea picked up early on, and it makes sense – the problem is that if a proper and full connection isn’t made between the plug and the port, it can be dangerous (particularly due to the high amount of current). eaten by the RTX 4090).
What doesn’t help is that the adapter setup can be quite taxing in some scenarios, as the RTX 4090’s massive size requires users to bend the cable a lot to attach it to the side panel of their case. although, as mentioned, we still don’t have definitive proof of the actual cause.
Hopefully, Nvidia will come out with a more revealing update soon, as this is surely one of the most awkward situations to plague a new graphics card in recent times.
