DG Matrix Joins the NVIDIA MGX Ecosystem to Power the Next Era of Accelerated Computing

DG Matrix is proud to join the NVIDIA MGX™ ecosystem as a solid-state transformer supplier for NVIDIA's 800 VDC power architecture. This milestone reflects more than two years of direct technical collaboration with NVIDIA, from the earliest prototypes of 800 VDC power architecture through the commercial launch of the Interport SST platform revealed at NVIDIA GTC 2026 in March.

The partnership sits at the center of one of the most consequential transitions in data center history. As accelerated computing rack power densities advance, the industry's entire electrical backbone is being architected for 800 VDC distribution. NVIDIA MGX is the modular rack-scale reference architecture for AI factories, and the Interport SST is the power platform purpose-built to meet it.

Recently this architecture was further detailed in SemiAnalysis’s latest deep dive study called "Inside the 800VDC Revolution – Part 1" on May 25, a landmark technical report that maps the industry's four-phase shift to 800-volt DC architecture and sizes the solid-state transformer market at $13 billion by 2030.

Why 800 Volts, Why Now

800 VDC is the power architecture and upgrade path that helps AI factories scale compute performance beyond the limits of traditional power distribution.

SemiAnalysis makes the constraint concrete: a one-megawatt rack running on today's 48-volt architecture requires roughly 200 kilograms of copper busbars. At one-gigawatt campus scale, that is hundreds of tons of copper. "Copper becomes unmanageable at 48 to 54 volts," the report states.

At 800 volts, the same 600-kilowatt load draws 750 amperes rather than 12,500. Resistive losses fall by a factor of 278. Future rack power density targets may not be reachable with legacy low-voltage distribution. SemiAnalysis projects that by 2030, approximately 39 gigawatts of incremental AI data center capacity will run on 800-volt architecture, with the transition saving more than 50 megawatts of continuous grid power per gigawatt of IT load.

"Each shift happened anyway, because physics and the economics of compute do not negotiate. 800 VDC is next, and the logic is the same." — SemiAnalysis, Inside the 800 VDC Revolution, May 2026

The Interport SST: Purpose-Built for NVIDIA MGX

The Interport SST was designed from the ground up for the demands of modular AI factory architecture. It natively supports 800 VDC today, with reprogrammable ports capable of reaching 1,500 volts to future-proof deployments against the next generation of accelerated computing platforms. A single-stage multi-port architecture delivers up to 98.5 percent conversion efficiency, integrated liquid cooling, and rack-proximate battery storage for dynamic GPU pulse-load response.

That last capability matters in ways the efficiency numbers alone do not capture. DG Matrix collaborated  with NVIDIA testing energy storage solutions for dynamic GPU load response, working through one of the hardest requirements in high-density AI compute: absorbing and supplying burst power at the speed of inference workloads. The Interport's multiport topology aggregates multiple AC and DC input sources simultaneously while delivering AC and DC outputs, giving operators a single converged platform for the full energy stack.

DG Matrix's roots run deep on this problem. SemiAnalysis traces the company's origin to NC State including its FREEDM Systems Center, where the CTO of DG Matrix has been researching solid-state transformers and silicon-carbide transistors since 2008. That lineage, combined with backing from Clean Energy Ventures including ABB and a SiC supply partnership with Infineon, gives the Interport platform a technical foundation built over more than a decade of development.

"The Interport SST brings modular, rack-proximate power that delivers the efficiency and dynamic response AI factories require, now for the NVIDIA MGX architecture," said Haroon Inam, CEO and co-founder of DG Matrix. "Collaborating with NVIDIA and MGX integrators helps customers adopt 800 VDC architectures with lower loss and higher power density. Our multi-port capability enables integrated behind-the-meter power aggregation from multiple AC and DC sources along with simultaneous AC and DC outputs, offering a future-proofed platform today."

An Industry at Its Turning Point

SemiAnalysis documents four phases of the 800-volt transition. The industry is currently entering Phase 1, retrofitting existing AC distribution with HVDC power racks. Phase 2, arriving in 2027 and 2028, brings 800-volt-native compute platforms like the NVIDIA Kyber rack online. Phase 3 takes 800-volt distribution facility-wide. Phase 4, the end state, replaces conventional step-down transformers and rectifiers with SSTs entirely.

The efficiency gains compound at each stage. A conventional AC power path achieves 82 percent cumulative system efficiency across seven conversion stages. A Phase 4 SST facility reaches 87.4 percent. At 1 gigawatt of IT load, that gap recovers 69 megawatts of continuous grid power. More than $320 million flowed into SST startups in the twelve months ending March 2026 as hyperscalers moved from pilots to commercial contracts, ahead of the regulatory milestones, because the engineering case is settled.

Building Together

As a member of the NVIDIA MGX ecosystem, DG Matrix is collaborating with NVIDIA and MGX integrators to validate rack power interfaces and develop 800 VDC reference designs for hyperscale, neocloud, and edge deployments across AI training and inference workloads. Pre-certification units are shipping now, with UL certification targeted for the end of Q2 2026.

The AI factory era runs on power. NVIDIA MGX defines the architecture. The Interport SST delivers the watts.
