Nvidia Launches DSX Ready to Qualify Power and Cooling Vendors

Nvidia used a September 21, 2026 newsroom post to introduce NVIDIA DSX Ready, a program that checks outside power and cooling products against the requirements written into its own DSX AI factory reference design. The program opens with two categories: battery energy storage systems, known as BESS, and cooling distribution units, known as CDUs. Nvidia frames the move as a response to a problem builders already face, that power, cooling, water, site and grid constraints now shape what an AI factory can actually deploy, and that choosing components which do not fit the wider design can waste the computing capacity a builder paid for.

The qualified list at launch names Hitachi Energy, LG Energy Solution and Tesla for battery storage, and LG Electronics, LiquidStack and Vertiv for cooling distribution. Nvidia says BESS partners run a defined set of qualification tests and submit the resulting data for its review, while CDU partners work through a self-qualification suite checked against Nvidia’s functional requirements. The company is explicit that clearing this process does not replace site-level engineering and does not by itself guarantee stability once a system is installed on a real site, so the badge narrows the search rather than finishing the job.

Nvidia positions DSX Ready as the connective layer between its DSX reference design, which treats compute, networking, power, cooling, facilities and software as one system, and the market of infrastructure suppliers building the physical pieces that go into a factory. The company says more categories across infrastructure and software will follow, which suggests the current battery and cooling list is a first slice of a wider vendor certification scheme rather than the whole of it.

The numbers

Nvidia’s post names qualified partners across the battery storage and cooling distribution categories at launch, but the company gave no figures for how many products it tested, how long qualification takes or how many additional vendors are in the pipeline, so no numbers block is warranted here.

For a builder sizing an AI factory today, the practical change is procurement rather than engineering. A qualification stamp shortens the list of battery and cooling vendors worth evaluating in detail, but it does not remove the need to model how a chosen product performs once wired into a specific site’s power draw and heat load, work that still falls to the builder and its own engineering team after the badge is checked.
