Power limitations for NVIDIA RTX 40 “Ada” GPUs are estimated at 800W on desktops and 175W on laptops

The leaker also claims that the power limit for desktop AD102 GPU is 800W. However, it is worth noting that the same leaker previously claimed that NVIDIA is currently validating an SKU with 900W power. This rumored SKU would have higher TGP than the now claimed limit, therefore either of the two rumors is incorrect. It is important to note the difference between power limit and TDP of actual GeForce SKU. The TDP should almost certainly be lower, while the power limit will lock overclocking from reaching a higher value. Therefore, the listed power limits may not necessarily apply to TDP of RTX 4090/4080/4070 and 4060 series, but rather how much power can be applied by board partners and through manual overclocking.

Consumer GPUs based on the NVIDIA Ada GPU architecture are projected to have higher TGP goals across the stack. Laptops with NVIDIA RTX 40 GPUs would have nearly equal power restrictions to current-generation laptops. The flagship AD103 mobile component, according to Kopite7kimi, will feature a TGP of 175W, which is the same as the current GA103 part, which was released earlier this year. Surprisingly, the AD104 GPU would have the same maximum TGP as the GA104 versions, which would be a 10W boost.

  • However, even when considering power limits, the TDP will be significantly higher for almost all RTX 40 SKUs by up to ~100W. It is unclear though if NVIDIA wants to equip all RTX 40 cards with the new PCIe Gen5 power connector that can alone provide 600W.
