DG Matrix announced the Interport™ solid‑state transformer (SST) platform, engineered to plug directly into NVIDIA’s MGX modular rack system and supply native 800 VDC power to GPU‑dense AI factories. The move positions the company at the forefront of the industry’s shift toward higher‑voltage DC distribution, a change that could affect power‑infrastructure planning for hyperscale and edge AI deployments.
DG Matrix Introduces Interport SST for NVIDIA MGX
DG Matrix, a global supplier of solid‑state transformer solutions, launched the Interport SST at NVIDIA GTC 2026. The platform delivers 800 VDC power directly to MGX racks and features reprogrammable ports that can handle up to 1,500 VDC for future needs. DG Matrix will work with NVIDIA and MGX integrators to validate rack power interfaces and produce 800 VDC reference designs. The company also highlighted a year‑long testing program with NVIDIA on energy‑storage solutions for dynamic GPU load response.
NVIDIA MGX Architecture and 800 VDC Strategy
NVIDIA’s MGX architecture is an open rack system that combines standardized compute, networking, and power modules. It adopts 800 VDC distribution to increase compute density, cut conversion losses, and simplify rack‑level power for AI workloads. DG Matrix’s Interport SST is purpose‑built for this architecture, offering a single‑stage, multi‑port design that eliminates complex conversion topologies. The platform claims up to 98.5 % conversion efficiency, rack‑proximate power with integrated battery storage, and dynamic pulse‑load response for GPUs.
Implications for AI Data‑Center Power Planning
AI training and inference workloads are driving unprecedented electricity demand, making power infrastructure a critical bottleneck. By delivering high‑density, low‑loss DC power at the rack level, the Interport SST could reduce both the physical footprint and energy losses of AI factories. Its multi‑port capability also supports simultaneous AC and DC outputs and aggregation from multiple sources, offering flexibility for hyperscale, neocloud, and edge deployments. DG Matrix’s collaboration with NVIDIA suggests the solution will be tested in real‑world MGX‑compatible installations.
Key Takeaways
- DG Matrix launched the Interport SST, a solid‑state transformer that provides native 800 VDC power to NVIDIA MGX racks and can be reprogrammed up to 1,500 VDC.
- The platform achieves up to 98.5 % conversion efficiency and integrates battery storage for dynamic GPU load response.
- DG Matrix will partner with NVIDIA and MGX integrators to validate rack power interfaces and develop 800 VDC reference designs for hyperscale, neocloud, and edge AI deployments.
EnergyInsyte's Take
The Interport SST gives AI‑focused utilities and data‑center operators a concrete option for higher‑voltage DC distribution, potentially easing power‑infrastructure constraints as AI workloads scale. Execution risk remains tied to the pace of MGX‑compatible deployments and the validation of multi‑port AC/DC aggregation in live environments. Executives should monitor reference‑design rollouts and real‑world efficiency data before committing to large‑scale retrofits.
