Insiders at have reported that NVIDIA is currently in the testing phase of different Total Graphics Power (TGP) designs for their upcoming GeForce RTX 50 series Blackwell graphics cards. These designs range from 250 Watts to 600 Watts. The company is exploring options from a 250 W design targeted at mainstream users to a more robust 600 W configuration aimed at enthusiasts seeking high performance.

The 250 W cooling system is expected to prioritize compactness and power efficiency, making it an attractive choice for gamers looking for a balance between capability and energy conservation. This design may be particularly appealing for those building small form-factor rigs or AIBs wanting to offer smaller cooler sizes. On the other hand, the 600 W cooling solution represents the highest TGP in the lineup, likely intended for testing purposes only. There are other SKUs with varying power configurations falling in between these two extremes.

It's worth noting that NVIDIA previously tested a 900-watt version of the Ada Lovelace AD102 GPU SKU, which never made it to market. Therefore, it's advisable to approach this current testing phase with caution. Engineering silicon is typically the initial batch created for software and firmware development, with the final silicon being more efficient and optimized for lower power consumption and alignment with standard TGP structures. The current top-tier SKU, the GeForce RTX 4090, operates at a 450-watt TGP. As more information becomes available, it's wise to reserve judgment until further details emerge.
