JPMorgan Chase details the transition to 800V DC electrical architectures for AI data centers

JPMorgan Chase outlines the evolution of data center electrical architectures toward 800V DC systems to improve power efficiency. The transition moves from traditional AC distribution to white space retrofits with 800V DC sidecars, then to native 800V DC servers that eliminate rack-level DC-to-DC converters, and finally to a full solid-state transformer (SST) architecture that provides a direct grid-to-chip power path for AI workloads.
Context
In a detailed report released in March 2026, JPMorgan Chase outlined the critical shift toward 800V DC electrical architectures for AI data centers to address mounting power constraints. As the bank projects global AI infrastructure and power spending to hit $5 trillion over the next five years, traditional AC architectures are being replaced by more efficient direct-current designs. The transition moves from traditional AC setups to 800 VDC sidecar retrofits, and eventually to Full SST (Solid-State Transformer) architectures. This final stage represents a "grid-to-chip" design that delivers power directly to native servers, eliminating multiple conversion losses.
This architectural disruption is driven by an "astronomical" demand for compute, with JPMorgan forecasting that 122GW of new capacity will be built between 2026 and 2030. JPMorgan analysts emphasized that the industry has "cargo-culted AC forward as far as we can," signaling an inflection point where conventional power chains can no longer support megawatt-scale AI racks. By bypassing traditional transformers and UPS systems, operators can reduce energy waste and equipment footprint, which is vital as power availability becomes a primary bottleneck for hyperscalers.
