Since a few of you have an RTX 4090, I think this may be of interest:

Here’s what’s happened to the 12VHPWR power cable of our NVIDIA RTX 4090 after two years of continuous work

So, after some stories that surfaced online about the melting issues of the 12VHPWR power cables for the RTX 5090 and the RTX 4090, I’ve decided to check the one we’ve been using these two years for the RTX 4090. So, what has happened to that power cable? Has it melted? Let’s find out.

Before continuing, I want to make it crystal clear that we’ve been using the official power cable for the RTX 4090 for over two years. We haven’t removed it when testing different GPUs. For instance, for benchmarking the RTX 3080, we’ve been using its own power cable. Same applies to the RTX 5080 and the RTX 5090. Moreover, the power cable is still working, and we haven’t encountered any stability issues.

So, here are some screenshots from the power cable. As you can see, it has signs of degradation. The plastic around one connector has been slightly melted. So yes, the melting issues are real.

As I said, the power cable and the RTX 4090 GPU have been working without issues. They still work without issues. And yes, when I installed the cable, I made sure it was plugged properly. Moreover, the melted connector is not as bad as those you might have seen online. However, we can all agree that there are things that need to be improved here.

For science, I also tried the power cable with the RTX 5090. I did not experience any crashes or stability issues. The RTX 5090 worked fine, and it ran games at full speed without any throttling issues or crashes.

The pic is a snippet from one of the article, to better see the damage.

As far as I know, none of you have had any problem with yours, but the next time you open the case to clean it, it wouldn't hurt to check how's the connector, just in case.
