According to a recent Reddit post, Nvidia is subtly upgrading its Best GPU the RTX 4090 Founders Edition, with the same modified 16-pin power connector recently found on the RTX 4070. The Redditor, known as u/prackprackprack, uploaded pictures to Reddit showing off the shortened sense pins on his RTX 4090. The changes were confirmed by other Redditors, comparing his images to images of older RTX 4090 FE cards.
The modifications made on the new RTX 4090 FE power connector include changes to the four sense pins that feed data to and from the GPU to the PSU. The pins have been retracted slightly inside the connector. This adjustment was apparently taken from the latest 12V-2x6 power connector specifications to ensure the power connector won't continuously feed power to the GPU if the 16-pin power cable is not inserted all the way. This should keep the graphics card safe from death due to fire or overheating, as we've seen with various RTX 4090 cards since launch.
