Seasonic revealed the specifications of the GeForce RTX 5080 SUPER

Seasonic quietly added the GeForce RTX 5080 SUPER to its PSU power calculator, which reads like a nudge that NVIDIA’s Blackwell refresh is no longer just vaporware. The entry isn’t an announcement, but it’s one of those small, practical placements that often foreshadow retail availability.

The headline figure is 415W TDP — about a 15% jump over the standard model. A plausible explanation: larger memory dies. In short, the switch to 3-gigabyte GDDR7 devices would raise memory power draw compared with 2-GB parts, and that can push the PSU/TDP numbers upward even if core clocks stay similar.

On the compute side, earlier reports say the GPU’s CUDA count won’t change; this leak doesn’t contradict that. So, a thirstier board (TDP up), more memory bandwidth or capacity (3-GB chips), but no extra CUDA hardware — a modest reshuffle, not a reinvention.
