There are free copper areas on the PCBs of the Geforce RTX 3090 Ti for a significantly more powerful power supply. This would make the board suitable for a TDP of 600 watts and thus also for the new GPUs from the RTX 4000 series.
With Nvidia’s new flagship, the Geforce RTX 3090 Ti, the GA102 chip is used in full for the first time. But that’s not the only change: The RTX 3090 Ti is also the first graphics card to use the new 12VHPWR power connector, and there are also changes to the PCB compared to the RTX 3090. It is striking that both the reference board and some custom PCBs would apparently be suitable for GPUs with a significantly higher TDP.
Unpopulated phases
The Twitter account @ghost_motley has put together some pictures of corresponding PCBs and marked free copper areas on which additional phases for the power supply and partly also a second power connection could be accommodated. On the reference PCB, seven additional phases are provided on the board, but not populated. While the Geforce RTX 3090 Ti is officially allowed a maximum of 450 W, it would be conceivable that the PCB would be suitable for the full 600 watts of the 12VHPWR connector.
The additional copper areas for further phases do not lead to any significant additional costs in production, so they could simply be leftovers from development. It is more likely, however, that Nvidia will use the RTX 3090 Ti specifically as a test platform for the new 12VHPWR connection, which is to become the standard for the new RTX 4000 graphics cards (“Ada Lovelace”).

If some of the chips from the new Ada Lovelace generation are pin-compatible with the GA102, it is even conceivable that the PCB of the RTX 3090 Ti will be used in parallel for the development of the new Geforce generation and later maybe even used in finished products. This would save costs for Nvidia and the board partners, since fewer different PCBs would have to be manufactured. But that is not certain. It therefore remains to be seen to what extent the PCBs of the RTX 4000 graphics cards will be reminiscent of their previous generation.
