Depending on the worload, 100% GPU utilization might render 30-90w of consumption. It all depends.
In my case, I use my GB10 down-clocked for less power consumption (lower temps) Cooler GB10 Temps - (almost) no performance lost , but with stock clocks, I see 90W on Prompt Processing and 45W in Token Generation.
But also depending on the model, this might change.
