As AI power demand scales from kilowatt-level processors to megawatt racks and gigawatt-scale campuses, traditional power architectures are reaching their limits. This whitepaper explores seven key predictions for the future of AI power delivery, from vertical power delivery and high-voltage server boards to disaggregated rack architectures, HVDC distribution and data center-wide DC microgrids.
- Bus-bar current limits that force the break from 48 V architecture
- Hold-up capacitor space penalty in conventional 12 kW PSU designs
- Trade-offs between 800 V-to-12 V and 800 V-to-50 V-to-6 V power delivery
- Grid stability risk from unmanaged GPU transient load patterns
