Many users of RTX 40 series GPUs, especially the RTX 4090, are still reporting the power cables burning and melting problem.

To make it easier to ensure this, Seasonic has recommended using a hair dryer to pre-bend the cables before installing the card.https://www.notebookcheck.net/Seasonic-recommends-using-hair-dryer-for-bending-RTX-40-series-power-cables.787446.0.html
