Nvidia claims DSX POD can cut water use up to 100% and power by up to 30%

Nvidia claims the DSX platform can reduce water consumption by up to 100 percent and power use by up to 30 percent for the same output. It connects liquid‑cooled compute with dry‑cooler‑based heat rejection that avoids evaporation, combining closed‑loop liquid cooling with outdoor dry coolers. When deployed at a 2GW scale, Nvidia says the design can save 54 million liters of water per day compared with conventional cooling‑tower systems, though some climates may need extra mechanical cooling during extreme heat.

The announcement also introduced DSX MaxLPS and DSX Flex. Ian Buck said the data centers could respond when the grid needs an extra gigawatt. MaxLPS dynamically allocates power to keep token output with 30 percent less power, while Flex lets AI data centers act as flexible grid assets, adapting workload power to utility needs, grid spikes and energy prices.
