HS-PC-01 / Power draw
Estimate peak watts,
cooling load, and breaker size.
Pick a tier, layer in optional RAM and storage, and read the published numbers for peak draw, idle floor, BTU/hr, the NEC-sized circuit breaker, and a suggested rack PDU SKU — all from one click.
HS-PC-02 / Run
One click · every tier.
The math runs server-side; what you see is a per-interaction result row pinned to the published burn-in, with the citation and the bench-in status surfaced inline.
Configuration
Pick a tier and the add-ons.
Numbers refresh live against the same published burn-in the rest of the catalog cites.
Tier
Pre-fills the matching tier and the addon summary on /quote.

HS-PC-03 / Sources
Where each number comes from.
Buyers cite the burn-in back to procurement; the calculator cites the same three pages so a quote engineer can verify in one click.
W2 peak — the only pinned number →
The 612 W wall draw is the published datasheet row on the home page; methodology on /benchmarks/rtx-5090#methodology.
W1 idle floor →
Measured on the 48-hour W1 burn-in profile; matches the RTX 5090 TGP published by NVIDIA. Citation: /benchmarks/rtx-5090#methodology.
W4 / RS — proposed →
Scaled from B200 TGP + catalog spec. No bench-in yet; the calculator renders an honest "Proposed · pending" until the founder pins a number.
Comparison row — three axes →
The thermal row on /compare is the same published burn-in the calculator cites, so the buyer is reading one number set across both pages.
HS-PC-04 / Hand-off
Spec it on /quote.
When you are ready, the calculator's CTA pre-fills the matching tier on /quote and folds the addon summary into the brief — so a sales engineer replies with a configuration already pinned to your power envelope.
