5 Principles for 800 VDC in AI Data Centers: Rack-level Architectures as the Immediate Enabler

As AI workloads push rack power densities beyond 400 kW, traditional AC and low-voltage DC systems are reaching their limits. The growing compute concentration in single racks demands rethinking power delivery for safety, efficiency, and scalability.

This white paper outlines five principles to guide adopting 800 VDC architectures tailored to facilities and goals. Topics include:

• Why rack-level 800 VDC "sidecar" power racks are the best near-term solution
• How protection, grounding, and energy storage must work as an integrated system
• Key operational and workforce readiness factors for scaling 800 VDC deployment

Read the white paper to navigate the shift to 800 VDC systems.
