Nvidia update on RTX 4090 GPU melting adapter reveals likely cause

NVidia has issued a statement regarding the RTX 4090 GPU and its investigation into power adapter melting incidents.

According to Team Green, one of the reasons the reported 12VHPWR adapters are melting is that they were not plugged in properly, and there have been about 50 reported cases worldwide.

In a statement, Nvidia said: “We are actively investigating the reports. We are aware of about 50 cases globally. Our findings to date suggest that a common issue is that connectors are not fully plugged into the graphics card.”

And Followed: “To help ensure the connector is secure we recommend plugging the power dongle into the graphics card first to ensure it’s firmly and evenly plugged in, before plugging the graphics card into the motherboard.”

In its conclusion, Nvidia states: “We are investigating additional ways to ensure that the connector is secure before powering on the graphics card.”

A couple of images were provided by Team Green to illustrate how the adapter should be seated, as well as another showing how it should not be fully plugged in.

The problem

All users affected by the melting adapter problem will benefit from “an expedited RMA process, regardless of the cable or card used,” so new RTX 4090 boards will be issued to them quickly.

The adapter might not have been fully plugged in, suggesting user error – but even if that’s the case, Nvidia will replace the damaged graphics card, as Gamers Nexus (GN) clarified. Nvidia told GN: “Anyone who has an issue [with the melting adapter] will be taken care of. We’ll expedite an RMA.”

A rough estimate of the number of RTX 4090s sold to date (from board partners) has been received by GN, and it is estimated to be around 125,000 units. Based on Nvidia’s official figure, 0.04% of the RTX 4090 user base has been affected by the issue, assuming 50 cards are affected (add your own seasoning, but this gives you some idea that the problem is not widespread).

The situation remains concerning, however, and we’ll be interested to see what Nvidia recommends when it mentions “additional ways” of securing the power adapter connector.

The obvious concern now, since we are hearing that the adapter may not have been properly seated, is that even if it is connected properly to begin with, if it is under any kind of strain – bent round to fit against the side panel of a PC case, for example – it is likely to loosen over time, causing problems.

It is hoped that Nvidia will provide further advice in the near future.
