3-pin to 8-pin adapter required for 450W

Nvidia’s new flagship, the Geforce RTX 3090 Ti, which will be unveiled on March 29, will feature a 16-pin PCI-E 5.0 connector and feature a TDP of 450 watts. The non-Ti variant released 1.5 years earlier was 100 watts less, so a 2 x 8-pin to 12-pin adapter could support up to 300 watts, including accessing the graphics card at 75 watts via the PCI Express interface .

Three-pin 8-pin adapter for the RTX 3090 Ti

With a TDP of 450 watts, you need it according to Videocardz a three-pin 8-pin power cable or a native implementation of 12VHPWR (PCI-E-5.0 12+4 pins) for the Geforce RTX 3090 Ti. However, power supplies with such a native cable shouldn’t be delivered yet in the period when the Geforce RTX 3090 Ti is already being introduced, so a PCI-E 5.0 3 x 8 to 16 pin adapter is required. . This provides 450 W for the Geforce RTX 3090 Ti alone. With the additional 75 W via the PCI Express interface, you would get 525 W. So custom designs of the Geforce RTX 3090 Ti would also be expected, which could reach a maximum TDP of 500 watts.

The 16-pin connector is virtually identical to the 12-pin connector. The difference lies in the four additional pins below, which make twelve 12 + 4 pins, and thus 16 pins. Nvidia’s next-generation Ada graphics cards, which will be released as representatives of the Geforce RTX 4000 series, are also likely to use the 16-pin PCI-E 5.0 connector. The Geforce RTX 3090 Ti should also be the latest GPU from Nvidia’s Ampere series and at the same time the first with fast 21 Gbit/s GDDR6X memory and the new power connection.
