| Caveat | These are rack power bases from HPE (GB200 NVL72, nominal TDP) and NVIDIA (GB300 NVL72, full-rack requirement in its reference architecture). Other GB300 OEM profiles run higher at peak, so size power to the configuration you buy. The figures say how much power the rack draws, not which cooling path it needs. |
