Overview
The choice between HVDC and traditional UPS-based power architecture is one of the most critical decisions for modern data center design.
Key Comparison Metrics
| Metric | Traditional UPS | 800V HVDC |
|---|---|---|
| System Efficiency | 88-92% | 94-97% |
| Conversion Stages | 4-5 | 2-3 |
| Rack Power Density | 10-30 kW | 50-150+ kW |
Recommendation
For new AI data center builds with power densities above 30kW/rack, 800V HVDC is generally the better choice.
