At Data Center World 2026, discussions highlighted the shift towards 800 VDC and new power architectures as a necessary response to the growing constraints on fitting compute, cooling, and power within server racks.
High Voltage DC Adoption

The increasing power demands of AI and compute are driving a shift towards higher voltage DC architectures. European alliances are collaborating on open standards to boost efficiency by reducing conversion steps. This approach aims to overcome rack-level constraints by rethinking power delivery at 800 volts.
Two European alliances are collaborating to promote open direct current distribution standards in data centers, aiming to enhance energy efficiency by minimizing redundant power conversion stages.
The adoption of 800 volt direct current architecture at the rack level is identified as the immediate technical enabler for implementing 800 volt direct current solutions within artificial intelligence data centers.
