All the RTX 4000 series will use the nerw 12v connector so it will be interesting to see if this issue follows on to the 4080 and 4070, for if it is improper pin connatct due to bennding the adapter, then it will crop up on the lower power cards, especially from AIBs who have highrr power draw, but in the end the mere perception will cause the most problems for Nvidia.
With AMD continuing to use the standard 6+2 connector, on the RX 7000 cards, it asks the question, if the PCIe 12v connector and its power adapter cable is as safe as the manufacturers say, why have AMD opted not to use it?
In the end this may prove nothing more than a new standards teething problems, and the Corsair 12v PSU cable, seems to be safe, but percption is everything and if you are going to spend hundreds of pounds on a new GPU, you want to feel it will not catch fire or see the power cable/socket melt, and given Nvidia already reported this problem to PCI-Sig, and then went ahead with using the standard, will not help them as many will see it as Nvidia not caring about the consumer.
In the end, Nvidia, regardless of how good the RTX 4000 series is, have not had the best of launches, it is undeniable the 4090 is the best card you can buy, and has an excellent performance uplift over previous generations, at present, but the launch felt underwhelming compared to previous lauches, and combined with the pricing for the 4080 16GB, and the disater that was the 4080 12GB (a 4070 if you were being charitable), has only soured many on Nvidia. In the end AMD this year only has to come close to the performance of, RTX 4000 series, and offer a sub-£1000, high end cards, 78XTX and 7800XT, and get a jump on the miod range, with a 7700XTX/XT, and Nvidia could be in trouble, but all we can do is hope, untiol 3rd November.
