Please note that this post is tagged as a rumor.

Rumored power limit for NVIDIA AD102 GPU is 800W, AD103 up to 175W

NVIDIA Ada GPU architecture of consumer GPUs is expected to have an increased TGP targets across the stack.

NVIDIA RTX 40 based laptops would have almost identical power limits as current generation. According to Kopite7kimi, the flagship AD103 mobile part would have a TGP of 175W, the same value as the current GA103 part that launched earlier this year. Interestingly, the same max TGP would apply to the AD104 GPU, and that would actually be an increase by 10W over GA104 models.

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.

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.
