As AI workloads accelerate, the shift toward AI factories is driving unprecedented rack-level power density. At the centre of this transition is NVIDIA MGX™, an open modular architecture that enables faster system design, improved scalability and rapid deployment of next-generation AI infrastructure.
As a valued member of the MGX ecosystem, Analog Devices, Inc. (ADI) is working alongside NVIDIA to help enable this transformation, delivering the power technologies required to support increasingly demanding AI factory deployments.
The Shift to 800VDC: Enabling AI Factory Scale
As AI factories push for ever-higher performance, traditional 48V architectures can no longer sustain the power demands of modern GPU clusters. To keep performance scaling, MGX-based AI factories are moving to 800VDC rack-level architectures, which reduce current and power losses, enable more compact distribution and support scalable designs targeting megawatt-class racks. This shift in power architecture is foundational for future NVIDIA platforms where continued performance gains depend directly on power delivery efficiency.
MGX and Modular Power Architecture
The open, modular nature of MGX extends beyond compute into power delivery.
New architectures are increasingly disaggregating power from the compute rack, enabling:
- Flexible system configurations aligned with evolving GPU platforms
- Faster adoption of new technologies across the ecosystem
- Optimised use of rack space for compute
800VDC Hot Swap: Enabling Always-On AI Infrastructure
AI factories operate continuously, making live serviceability essential.
Hot swap controllers play a critical role by enabling safe insertion and removal of server trays without interrupting operation. At 800VDC, this introduces new challenges, including:
- Precise control of high-energy inrush currents
- Robust fault detection and system protection
- Real-time telemetry for system monitoring
ADI: Enabling 800VDC Power for MGX Systems
ADI is extending its leadership in power protection, control, and telemetry to support next-generation AI infrastructure.
Building on decades of innovation, ADI is developing high-voltage hot swap and DC-DC solutions that deliver:
- High-density integration for advanced compute platforms
- Fast, accurate protection in high-voltage environments
- Advanced telemetry for system optimisation and predictive maintenance
Enabling the Future of AI Factories
As AI infrastructure evolves toward modular, open architectures built on NVIDIA MGX, 800VDC power delivery becomes a cornerstone of scalability and efficiency.
Through continued collaboration within the MGX ecosystem, ADI is helping enable the next generation of AI factories – delivering the protection, conversion and intelligence required to power advanced AI systems with confidence.
