We have also heard that to support such extreme specifications and the massive increase in SM / Core Count on the AD102 GPU, the top NVIDIA GeForce RTX 40 GPUs such as the RTX 4090 or RTX 4090 Ti could feature a TDP of up to 850W.

NVIDIA is already investing development around the new PCIe Gen 5 connector that offers up to 600W power input per connector. The delayed GeForce RTX 3090 Ti is one example where the card is expected to rock at a TGP of 450W and will be the first desktop graphics card to utilize such a connector interface. The next-gen cards are also expected to utilize the same PCIe standard but it looks like the top variant could end up with two Gen 5 connectors to supplement the ~800W power requirement.

Several PSU makers have already started releasing their brand new Gen 5 power supplies which would include the necessary connectors to support the next-gen GPUs but they only feature one primary Gen 5 connector which means that if NVIDIA was to use a second 16-pin port, users will have to use a 2x 8-pin to 1x 16-pin adapter which will ship with most of these PSUs.
