800 Volts and Beyond: Reinventing Rack-level Power Architectures for the GPU Era

800 Volts and Beyond: How Rack-level Power Architectures are Being Reinvented for the GPU Era

The GB200 NVL72 rack draws approximately 120 kilowatts. Its successor, the Vera Rubin NVL144, targets around 200 kW. At those densities, the 48-volt power architecture that served the cloud era well has become the bottleneck, and the industry has Read more

The Transformer Shortage Nobody Saw Coming: How a Quiet Component Crisis Is Throttling Data Center Power Delivery

A 200-ton steel box filled with copper wire and transformer oil is now the single most constrained item in data center construction. Semiconductor lead times have compressed, structural steel is broadly available, and capital is abundant. But a large power transformer ordered today from a Tier 1 manufacturer will not arrive for four to five years. Read more

Discover how data centers can meet rising power demands, improve efficiency, and maintain reliable operations with advanced power-management solutions. Read more

Europe’s Data Center Power Problem is Wires, NOT Watts

IEA analysis of data centre location data from Omdia's Data Center Building Tracker

Europe is not short on electrons or capital. It is short on transmission, substations, and administrative throughput. That makes the European power question a fundamentally different engineering and commercial problem than the one US developers are solving. Read more

800 VDC and the Race to Power the AI Factory

By: Maurizio Di Paolo Emilio, Contributing Editor at Data Centre Digest

Artificial intelligence is pushing data-center power architectures into territory they were never designed to handle. As AI accelerators become more powerful, rack power is moving from tens of Read more

AI & Energy: Bending the Curve

Accelerate the Artificial Intelligence Revolution

How AI is scaling at a pace that is reshaping semiconductor roadmaps, data center design, and long-term infrastructure strategy. Read more

Power Integrity in AI Racks: The Next Bottleneck in Next-Generation Data Centers

The fast growth of computational density of AI accelerators is fundamentally changing the design of power delivery networks (PDNs). Although rack power levels have increased from tens of kilowatts to several hundred kilowatts, processor core voltage levels have been kept below 1 V, forcing current levels to rise sharply.

Power, Cooling, and Sustainability: Solving the 2026 AI Data Center Energy Crunch

Demand for AI is strong. Land is often available. Network routes can be engineered. But in many markets, the grid is the hard limit, and AI workloads are pushing up against it. Read more

Why AI Data Center Power Should be Built Like AI Compute

AI has outgrown legacy power architecture. Enphase IQ Solid-State Transformer (IQ SST) will deliver megawatt scale

Raghu Belur, Co-Founder and Chief Product Officer at Enphase Energy discusses how voltage and density jumps of the next few years will lock in data center power architectures. The most important decision in this transition is architectural, and it gets skipped over. Read more
