Why Scaling AI Compute Performance Requires a New Power Architecture
NVIDIA, Google, and Microsoft are standardizing an 800 VDC power architecture through the Open Compute Project to improve efficiency in AI factories. This approach reduces power conversion stages between the electrical grid and compute accelerators.
Why it matters
This enables data center operators to increase compute performance and density without replacing existing building electrical infrastructure, preventing previous facility investments from becoming obsolete.
The details
- Over 80 manufacturers are developing products based on these open specifications.
- A hybrid power rack for existing AC facilities arrives in second half 2026.
- Row power centers supporting 2 megawatts per row are expected by 2027.
