GeForce RTX 3090 Ti graphics cards will include a 3x8-pin to PCIe Gen5 power adapter

It seems that the new NVIDIA GeForce RTX 3090 Ti that will arrive at the end of the month has a TDP of 450W. With such high power consumption, two 8-pin PCIe is not enough, such configuration can only support 300W power.

The The original RTX 3090 launched in 2020 came with two 8-pin connectors and up to 3 on some top-of-the-range models. Obviously, this was enough for the 350 W TDP, plus the card has access to an extra 75 W of power via the PCIe interface.

With the RTX 3090 Ti we will have a TDP of 450W so you will need three 8-pin power cables or a native 12VHPWR (12+4 or 16-pin) PCIe Gen5 implementation. However, native wired power supplies won’t be available in time for the RTX 3090 Ti, which launches on March 29. For this reason, the adapter is required.

The adapter will provide 450 W of power alone and a total of 525 W with the PCIe interface. Surely the custom models of the RTX 3090 TI will reach 500 W maximum TDP.

To refresh your memory, I remind you that the RTX 3090 Ti has a GA102-350 GPU with all active cores, a total of 10752 CUDA. This is NVIDIA’s first RTX model with 21Gbps GDDR6X memory and a new power connector.
