This crossed my mind so have gone for a Cable Mods adapter to use with current Corsair PSU which powers the 4090 fine through pig tails, but don’t like it as the tidally. CM do a 4 socket to 16 pin adapter so plenty of consistent juice should be available.With the dangerous adapter it's unfortunate that no ATX 3.0 PSU's have showed up. Although it seemed the 1200W Thermaltake would be in stock soon they went way overdue. I wonder if the PSU companies are now worried about their cables and are holding them back.
