There were no problems with this monster, apart from the installation: you need a case big enough to accommodate it, and I had to struggle a bit to install the huge 'anti-kink' bracket, which is essential because the card weighs over 2kg...
No problem with the 12VHPWR cable, just plug it in and there's no problem. In any case, this version of the 4090 is slightly limited and can't consume more than 450W, the problems of melted connectors appear when you exceed 600W of consumption as on other models.
