| Source | Composite across products and power boundaries; each figure has its own document. HPE QuickSpecs (GB200 NVL72, 132 kW rack TDP); Lenovo Press LP2357 (GB300 NVL72, 135 kW rack TDP, up to 155 kW peak); NVIDIA Enterprise RA and DSX Facilities Infrastructure Design Guide v2.0 (GB300 up-to-142 kW and VR200 330 kW facility design bases); Pegatron RA4803-72N3 (VR200 188 kW Max Q, 228 kW Max P); NVIDIA GTC 2025 keynote, reported by Tom's Hardware (Rubin Ultra / Kyber ~600 kW). Rack TDP, peak draw and facility design basis are different boundaries and must not be compared like for like; the ~600 kW entry is a roadmap planning point, not a shipping specification. |
