der8auer explores this topic and explains why it is incorrect to immediately assume user error or poor cable quality. He examined the damaged card under a microscope and confirmed that he frequently uses Moddiy cables for his own products, verifying that they are of high quality. The card’s connector, as well as the PSU side, was also pictured under a microscope. It turns out that RTX 5090 FE cards have an uneven distribution of power across all 12V cables. Under a thermal imaging camera, it became obvious that only two cables out of four heat up significantly more than the others, with the PSU connector side reaching a shocking temperature of 150°C.
