NVIDIA launched DSX Ready on 21 September with six names: Hitachi Energy, LG Energy Solution and Tesla in batteries, LG Electronics, LiquidStack and Vertiv in cooling. Restatements and coverage have already drifted into the batteries an AI factory is allowed to use. No quantity comes with the badge.
NVIDIA's battery qualification guidelines, dated 28 May, put size outside the boundary: "battery sizing is irrelevant to qualification." Qualification stops at the AC terminals; the twelve tests score inverter behaviour there, and none measures a megawatt-hour. Test 4 asks the partner for its own assumed IT load, leaving no NVIDIA ratio of storage to compute to multiply by the gigawatts being built. Required duration sets that figure, as our August piece showed.
Nor is the list a rubber stamp. Fluence sits inside the Siemens DSX Vera Rubin design, 136 MW of facility for 100 MW of IT, and is not on it. NVIDIA's FAQ attaches the badge to a product rather than to a partner or its portfolio: Vertiv qualified one 2.3 MW CoolChip; Tesla named no model at all. A gate on who may bid is not an order.
NVIDIA Launches DSX Ready to Qualify Power and Cooling Products for AI Factories — 21 September 2026
Launch list and FAQ wording are NVIDIA's, published 21 September; the sizing exclusion, the AC-terminal boundary and twelve tests come from its battery self-qualification guidelines of 28 May 2026. CoolChip's rating comes from Vertiv's release of 21 September and the Megapack qualification from Tesla's own announcement; the facility and IT load are the Siemens design of June. Nothing here is derived.
