Delta has announced the integration of 800-VDC power systems and advanced cooling solutions specifically designed for AI factories. This new infrastructure aims to address the extreme power density and thermal management challenges posed by next-generation AI workloads.
Overview of Delta's Integrated AI Factory Infrastructure
Delta Electronics has announced the development of a comprehensive power and thermal infrastructure approach specifically engineered for next-generation AI factories. Announced in late September 2026, this initiative is fundamentally based on the NVIDIA DSX AI Factory Platform. The NVIDIA DSX platform combines reference designs, software, accelerated computing systems, facility infrastructure, and partner technologies into a unified framework for designing, deploying, and operating AI factories. Within this complex architecture, Delta Electronics focuses on the critical infrastructure situated between the primary power source and the AI compute rack. By doing so, the company aims to significantly reduce conversion losses, manage extreme thermal loads, and maximize the compute performance supported by available electrical capacity in high-density AI environments.
Technical Details: 800-VDC Power Architecture
At the facility level, Delta integrates energy storage systems, solid-state transformers, and medium-voltage infrastructure to store, convert, and distribute power to high-density AI workloads. In the IT space, the company combines 800 VDC power delivery with advanced liquid cooling that extends from the row directly to the chip. This approach is intended to coordinate power delivery and heat removal with the rapidly changing demands of GPU workloads. The 800 VDC architecture significantly reduces the number of power-conversion stages between facility infrastructure and computing equipment. Delta reports power-conversion efficiency of up to 98 percent, alongside a fast response to GPU load transients. Its high-density in-row systems can provide up to 800 kW in a single power rack, while battery and capacitance-based backup technologies address transient power requirements. At the board level, 800 VDC DC-DC conversion technology steps the voltage down directly to 50 VDC or 12 VDC, achieving a peak efficiency of up to 98.5 percent.
Advanced Thermal Management Solutions
Thermal management is deeply integrated into this infrastructure strategy to handle the immense heat generated by modern AI accelerators. Delta offers liquid-to-liquid cooling distribution units rated at 2.4 MW and 3 MW. These are complemented by in-rack cooling and component-level thermal solutions designed specifically for high-density AI systems. By extending liquid cooling from the row to the chip level, the infrastructure effectively mitigates thermal bottlenecks, ensuring that compute performance is not throttled by heat dissipation limits during intensive training or inference workloads.
Prefabrication and Modular Deployment Strategies
To accelerate deployment schedules in a highly competitive market, Delta is applying prefabrication and modular construction methodologies. Its Prefabricated AI Modular Data Center Solution integrates 800 VDC in-row power delivery with 3 MW of liquid-cooling capacity within factory-assembled and tested infrastructure blocks. Moving the integration and validation processes offsite is intended to drastically simplify onsite commissioning. This modular approach also enables phased expansion, allowing operators to scale their facilities incrementally as AI compute requirements increase over time.
Implications for AI Data Center Design
The integration of these technologies represents a paradigm shift in AI data center design. By coordinating power stages and reducing electrical losses, the architecture minimizes heat generation, copper requirements, and unused power capacity. The shift to 800 VDC architectures directly addresses the extreme power density challenges posed by next-generation AI workloads. Connecting energy availability directly with compute performance ensures that the massive electrical capacity required by AI factories is utilized with maximum efficiency, reducing the overall total cost of ownership and environmental footprint of the facility.
Future Outlook for High-Density Compute
As AI models continue to grow in complexity, the demand for high-density compute will only intensify. Delta's integrated approach, combining onsite energy systems, 800 VDC architectures, and modular liquid cooling, provides a scalable blueprint for future AI factories. The ability to phase expansion through prefabricated modular blocks ensures that infrastructure can keep pace with the rapid evolution of accelerated computing systems. Ultimately, this holistic integration of power and thermal management will be critical for operators looking to deploy and sustain the next generation of AI infrastructure efficiently and reliably.
