Calculate continuous megawatt power consumption, monthly and annual operating electricity bills, and required cooling tonnage for NVIDIA GB200 NVL72 Liquid-Cooled Rack at Iceland Geothermal Renewable ($0.05/kWh).
An 8-node deployment draws 960.0 kW of IT power. At a PUE of 1.1, total facility load is 1056.0 kW, consuming hundreds of megawatt-hours yearly.
Direct-to-chip liquid cooling reduces cooling fan and chiller power, dropping PUE from ~1.35 to ~1.15 and cutting facility power consumption by up to 15-20%.
Over a 3-5 year server lifecycle, electricity bills frequently exceed the initial hardware capital cost. Every 0.1 reduction in PUE saves tens of thousands of dollars per megawatt annually.
