According to the leaks we all already know about, NVIDIA’s next flagship graphics card, the RTX-3090Tiwill have a TDP nothing more and nothing less than 450 watts, which assumes a consumption that even with two 8-pin PCIe connectors of the power supply we will have enough. However, it looks like NVIDIA is going to give (even in custom models) a adapter which will allow us to use three 8-pin PCIe connectors current sources with the new 16-pin PCIe 5.0 connector that the RTX 3090 Ti will bring from the factory.
What we’re telling you is a substantial difference from the current RTX 3090; the Founders Edition version of the RTX 3090, released in 2020, has an additional 12-pin power connector, and these versions also come with an adapter from two 8-pin PCIe to this 12-pin connector, which was sufficient for your TDP of 350 W. , but insufficient for the RTX 3090 Ti if the leaks are confirmed and its TDP rises to 450W.
The RTX 3090 Ti’s PCIe 5 adapter is handy
As we mentioned, the Ti version of the RTX 3090 would have 100 watts more TDP than the current graphics card, and with the size of the TDP would require a total of three 8-pin PCIe connectors from the power supply. , or a native implementation of power with the standard 12VHPWR (12 + 4 or 16 pins), something that has not yet been standardized in the market and in fact the first sources with it are not expected to hit the market before the launch of the 3090 Ti ( which in theory is launched on March 29).
For this reason, and since it seems that NVIDIA will only launch this model of graphics card with a 16-pin power connector (in principle there will be no versions with 3×8 pins), the use of this adapter will be absolutely necessary. This is a unilateral decision by NVIDIA for a “future release” of these graphics cards, but we must also recognize that it is more comfortable to connect a single connector to the source instead of three (fewer cables, less space occupied, etc.).
Thanks to this we will be able to provide up to 450W of power directly to the graphics card, which added to the 75W provided by the PCI-Express socket already, we add a total of 525 watts available for the GPU, something that will be useful because despite the fact that the NVIDIA reference model would have 450W of TDP, it is highly likely that the custom models from the assemblers will increase this figure to 500W due to the overclock with which they usually arrive from the factory.
Recall that the NVIDIA GeForce RTX 3090 Ti will feature the GA102-350 GPU with all CUDA cores enabled, 10,752 in total. This will also be the first RTX graphics model with 21Gbps GDDR6X and the new power connector, so expectations are quite high in that regard; We’ll see if there’s stock later and at what price, and then we can discuss whether it’s worth it or not.
