Delta Showcases 800VDC Power Architecture and Liquid Cooling for AI Factories at NVIDIA GTC 2026
Rising power consumption and heat density in AI server racks have made the conversion losses of conventional AC power systems and the limits of air cooling bottlenecks to expansion. NVIDIA is therefore promoting an 800VDC architecture for next-generation AI factories. Delta Electronics is integrating power, liquid cooling and microgrid technologies in a push to evolve from a component supplier into a data-center systems provider.
NVIDIA GTC 2026 opened in San Jose, California, on March 16, 2026. On March 17, Delta showcased a 660kW in-row power cabinet with 480kW of redundant capacity and conversion efficiency of up to 98%, as well as 2.4MW and 3MW liquid-cooling CDUs. DIATwin, integrated with NVIDIA Omniverse, has already been deployed on an AI server power-supply production line in Thailand. No investment amount was disclosed.

The history behind this eventDelta Builds ‘Grid-to-Chip’ Architecture to Meet Surging AI Data-Center Power Demand
Generative AI is driving up computing density in data centers, making power supply, cooling and grid resilience bottlenecks to industry expansion. Delta Electronics believes AI competition is extending beyond chip performance to energy and infrastructure. It is therefore integrating microgrids, power conversion and liquid-cooling technologies into a one-stop “grid-to-chip” architecture.
Delta Electronics Chairman Yancey Hai said at COMPUTEX 2026 that next-generation AI racks are closing in on 1 MW of power, beyond what conventional power-delivery and air-cooling designs can handle. The company showcased its latest solid-state transformers, liquid-cooling systems and modular AI data-center solutions, which it says can cut deployment time by about 60% while improving energy efficiency and power resilience.
LITEON Showcases 800 VDC Power Solution at GTC for Next-Generation AI Data Centers
Generative AI is increasing per-rack power consumption, leaving conventional low-voltage power supplies and air cooling constrained by conversion losses and heat-dissipation bottlenecks. LITEON Technology has therefore integrated power supply, energy management and liquid-cooling systems into an 800 VDC architecture supporting NVIDIA Vera Rubin, improving power efficiency and operational stability for megawatt-scale AI data centers.
LITEON showcased an 800 VDC Power Rack, a 110 kW Power Shelf, a liquid-cooled rack based on NVIDIA MGX and a 2.1 MW in-row CDU at NVIDIA GTC 2026 from March 16 to 19, 2026. The company said the solutions could accelerate megawatt-scale deployments but did not disclose investment, order or pricing figures.
