Reports of damaged RTX 5090 power connectors continue to appear, with Club386 and YouTuber Daniel Owen both recently sharing cases involving melted 16 pin connections. Their experiences have renewed criticism of the 12V 2x6 connector used on NVIDIA’s highest power graphics cards.
Club386 reported that its GeForce RTX 5090 Founders Edition suffered visible damage around the power connection. Photos showed a burnt cable connector, along with damage at the graphics card and power supply ends. The system reportedly used a single native 12V 2x6 cable connected to a 1000W Be Quiet Dark Power 13 power supply.
That detail is important because many earlier discussions focused on adapters as a possible cause of failures. In this case, Club386 said it was not using a multi cable adapter. The outlet received a replacement graphics card through the RMA process, but it argued that a failure of this kind should not happen on a flagship product.
A Second RTX 5090 Case Involved an Adapter Cable
Daniel Owen also reported a melted power connector on an RTX 5090 Founders Edition. His setup used a four 8 pin to 12V 2x6 adapter, which is a different configuration from Club386’s native cable setup.
Adapters have often been treated as a greater risk because they add another point where the connection can be incomplete, bent too sharply, or unevenly loaded. However, the Club386 report suggests that adapters are not the only concern. Cases involving native cables have also been documented since the RTX 5090 launched.
The exact reason behind any individual connector failure can be difficult to confirm without a detailed technical inspection. Cable seating, connector condition, power delivery, bending near the plug, manufacturing variation, and heat can all affect the result. Still, repeated reports have led many PC builders to question whether the connector design provides enough margin for graphics cards that can draw very high amounts of power.
| Reported Case | Graphics Card | Power Connection | Reported Damage |
|---|---|---|---|
| Club386 | RTX 5090 Founders Edition | Native single 12V 2x6 cable | Cable, GPU connector, and PSU side affected |
| Daniel Owen | RTX 5090 Founders Edition | Four 8 pin to 12V 2x6 adapter | Melted connector reported |
What RTX 5090 Owners Should Check
Anyone using an RTX 5090 or another high power RTX 50 series card should inspect the connector regularly. The plug should be inserted fully and should not show gaps between the cable and the graphics card socket. It is also sensible to avoid sharply bending the cable immediately after the connector.
A native cable from a reputable power supply maker remains preferable when available, since it reduces the number of connections in the power path. That does not guarantee a problem will never occur, but it avoids relying on an additional adapter.
You should also watch for warning signs such as a burning smell, discoloration, unstable power behavior, unexpected shutdowns, or heat around the connector area. If any of these appear, turning off the system and checking the connection is the safest response.
The RTX 5090 is one of the most powerful consumer graphics cards available, but its power demands have made the 16 pin connector an ongoing concern. As more reports emerge from reviewers, publications, and PC enthusiasts, pressure is likely to grow for a more robust solution in future NVIDIA graphics card designs.
