GPU TDP vs facility power
A worked example and the assumptions to document.

AI compute needs a complete power model.
Build an explicit chain from equipment inputs to IT demand, facility overhead and capacity assumptions.

Three boundaries to keep separate
- GPU component: one part of the server, not the total AC input.
- IT equipment: servers, networking, storage and other IT loads within your boundary.
- Facility: IT plus cooling, electrical losses and other building overhead.
Use whole-server data or measurements where possible. If using chip power, explicitly add the rest of the system; do not call that value a complete server rating.
Carry inputs forward: use “Use IT load in capacity planner” below the calculator, then review and apply the IT MW and PUE on the next page. Other planning assumptions are preserved. You can also enter these values manually.
