NVIDIA RTX 4090 Power Connector Melting/Burning Possibly Due to “Loose Connections”

NVIDIA’s RTX 4090 power connector meltings have become the talk of the digital town. Experts have cited the possible reasons for this little bonfire, but we’re yet to get an official statement from NVIDIA. JohnnyGuru, Corsair’s resident PSU expert, also has some interesting hypotheses on the matter. According to Johnny, the cause of the impromptu blazes is rather simple. Loose connections:

In the above picture, we can see that there’s no gap between the 12VHPWR connector and the adapter. The two are firmly in place, eliminating the possibility of thermal damage. Below is an example of an incorrectly plugged connector, something we’ve seen across most of the reported incidents.

Pushing the connector all the into the socket can be particularly hard, given its titled orientation and the bulky form factor. Unfortunately, this would mean that the melting of these cables may not have been due to bending or low-quality solder. In the end, you have a lot to consider if you’re the owner of a new RTX 4090.
