The GeForce RTX 4080 Super Founders Edition introduces modifications to its design, particularly in the power supply configuration. The original GeForce RTX 4080 Founders Edition featured a 13-phase voltage regulation module (VRM) for the AD103 GPU and a 3-phase power supply for its 16GB GDDR6X memory. The updated GeForce RTX 4080 Super Founders Edition, however, adopts an 11-phase VRM for the GPU and a 2-phase power supply for the memory. This change was highlighted by the reviewer Geekerwan, suggesting a simplification of the printed circuit board (PCB) design.

The rationale behind this modification is likely tied to the reduced performance variability of the AD103 graphics processor, which negates the necessity for a highly robust power supply, given the GPU's operation with 10,240 CUDA cores at frequencies reaching up to 2,550 MHz. The revised 11+2 phase VRM configuration is deemed adequate for the majority of the chips, ensuring they meet their performance specifications. This optimization in the PCB design contributes to lower production costs, allowing Nvidia to price the high-end GeForce RTX 4080 Super Founders Edition at a more affordable $999, a decrease from the initial $1,199, while still sustaining profitability. Such design changes are not expected to significantly affect the product's reliability.
