Delta Electronics is proposing an integrated power and cooling system for NVIDIA DSX AI factories, linking onsite energy storage to the chips doing the computing. The idea is to treat electricity delivery, heat removal, and GPU infrastructure as one coordinated system, rather than a series of separate data-center components. At the center is an 800-volt direct-current architecture. Delta says this can reduce the number of power-conversion steps between a facility and its GPU racks, reaching up to 98 percent conversion efficiency. Its board-level DC-to-DC equipment then steps power down to 50 or 12 volts, with a claimed peak efficiency of 98.5 percent. The scale is substantial. Delta says one high-density, in-row power rack can deliver as much as 800 kilowatts. Its prefabricated modular solution combines that 800-volt distribution with up to three megawatts of liquid-cooling capacity. Battery and capacitance backup systems are intended to absorb the rapid power fluctuations produced by dense GPU workloads. Prefabrication is a key part of the commercial pitch. Delta plans to assemble and test infrastructure modules offsite, which it says could simplify commissioning and support phased data-center expansion. NVIDIA says the approach could help customers deploy DSX-based AI factories faster and produce more AI work from each megawatt. The important constraint is that Delta’s efficiency and deployment claims still need to be demonstrated in operator deployments. The open question is whether the full facility-to-chip package performs as well in production as it does in the design.

Story brief

3 key points

Delta Electronics is packaging power delivery, energy storage, medium-voltage equipment, liquid cooling, and chip-level power into an infrastructure stack for NVIDIA DSX AI factories. The proposed design uses 800 VDC distribution, with claimed conversion efficiency of up to 98% and board-level efficiency of 98.5%. Delta also says its in-row systems can provide up to 800 kW and its prefabricated modules 3 MW of...

  1. 01

    Delta’s 800 VDC architecture is designed to reduce power-conversion stages between the facility and GPU racks.

  2. 02

    Delta claims up to 800 kW per high-density in-row power rack and 3 MW of liquid-cooling capacity in modular systems.

  3. 03

    Prefabrication shifts integration and testing offsite, potentially simplifying commissioning and phased data-center expansion.

Delta Electronics has developed an integrated energy, power-delivery and liquid-cooling offering for AI factories built on NVIDIA DSX. The effort connects equipment from onsite energy storage through rack and chip-level power, aiming to help operators bring GPU capacity online faster and produce more AI work from a fixed power supply.

The announcement shifts Delta’s pitch beyond a single data-center component. Its proposed stack includes energy-storage systems, solid-state transformers, medium-voltage equipment, facility and rack power, liquid cooling, and chip-level power solutions. Delta’s goal is to coordinate the electricity arriving at a site with the equipment consuming it inside dense GPU systems.

A higher-voltage route into the rack

At the center is an 800-volt direct-current architecture, a higher-voltage route intended to reduce the number of power-conversion stages between a facility and its computing hardware. Delta says the architecture can achieve up to 98% power-conversion efficiency. Its board-level DC-DC equipment, which steps power down to 50 VDC or 12 VDC, has a claimed peak efficiency of up to 98.5%.

Delta’s stated infrastructure specifications
Up to 800 kWIn-row power rack

Delta said its high-density in-row systems can deliver up to 800 kW in one power rack.

3 MWLiquid-cooling capacity

Delta’s prefabricated modular data-center solution combines 800 VDC in-row power with 3 MW of liquid-cooling capacity.

Up to 98.5%Board-level efficiency

Delta said its board-level DC-DC power distribution technology can reach peak efficiency of up to 98.5%.

Those are Delta’s stated specifications. NVIDIA positions DSX around increasing token production from the power a facility already has, making the power path and cooling load part of the platform’s larger efficiency argument.

Factory assembly is part of the pitch

Delta’s delivery argument rests partly on prefabrication. Its Prefabricated AI Modular Data Center Solution puts 800 VDC in-row power and 3 MW of liquid-cooling capacity into infrastructure blocks assembled and tested before they reach a customer site. Delta says moving integration and validation offsite reduces onsite complexity, streamlines commissioning and supports phased expansion.

What Delta is combining

  • Onsite energy storage, power conversion and medium-voltage distribution at the facility level.
  • 800 VDC power delivery and row-to-chip liquid cooling in the IT space.
  • Battery and capacitance backup technologies intended to support rapid GPU power swings.

The full-system test remains ahead

NVIDIA said Delta’s expertise in 800 VDC delivery and liquid cooling will help customers deploy DSX-based AI factories faster and get more AI performance from each megawatt. The next test is how the integrated package performs in operator deployments.

Delta is offering a connected approach to power quality, heat removal and computing equipment. Its case for faster productive capacity rests on combining those layers from the facility through the rack and into the chip.
