AI infrastructure is reshaping more than the servers inside data center racks. As GPU-intensive workloads push rack densities higher, Eaton, NVIDIA, Google, Microsoft and others are advancing direct-current power architectures designed to deliver more power with fewer conversion stages and less physical infrastructure.
For solution providers, integrators and infrastructure partners, that shift could broaden the scope of AI infrastructure projects. Moving from traditional AC designs toward rack-level 48/50V DC and, eventually, 800 VDC affects not only power distribution but also backup systems, cooling, rack design and serviceability — forcing partners to think about those systems as an interconnected architecture rather than separate infrastructure purchases
Why AI is pushing data centers toward DC power
The broader demand curve explains why power architecture is receiving so much attention.
The International Energy Agency projects global data center electricity consumption will roughly double from 485 TWh in 2025 to approximately 950 TWh in 2030, with consumption from AI-focused data centers growing even faster.
Inside the facility, higher density creates another challenge: current. Delivering more power at lower voltages requires greater current, which can mean larger conductors, greater losses, and more heat. Higher-voltage DC distribution can reduce current while eliminating some power-conversion stages between the utility feed and IT equipment.
48V, 50V and 800 VDC architectures take shape
The transition is already visible at the rack level. Open Compute Project’s Open Rack V3 ecosystem uses 48V DC busbar architectures, while Eaton’s upcoming 50V DC system is designed for both conventional 19-inch racks and 21-inch ORV3 racks, with power ratings ranging from 33 kW to 132 kW per rack.
Eaton specifically identifies system integrator builds, enterprise and colocation environments, AI/HPC deployments and OCP migration projects among its intended applications.
The next step could be significantly larger.
NVIDIA, Google and Microsoft are collaborating through OCP to establish 800 VDC as an open architecture for next-generation AI data centers. NVIDIA says moving from today’s lower-voltage rack architectures toward 800 VDC reduces current, copper requirements and cable bulk while allowing fewer power-conversion stages. More than 80 equipment and infrastructure companies are participating in the ecosystem.
Eaton is among them and is developing 800 VDC infrastructure alongside its current ORV3 and 50V DC offerings.
DC power creates a broader infrastructure role for partners
That does not mean every enterprise data center is about to switch to 800 VDC.
In fact, the emerging market is better understood as a continuum. Existing facilities can continue operating AC infrastructure while introducing DC closer to high-density compute. Rack-level 48/50V systems offer another path, while 800 VDC is being positioned for future AI environments with substantially greater density. NVIDIA’s own roadmap explicitly includes hybrid architectures designed to introduce 800 VDC power racks into facilities with existing AC infrastructure.
For the channel, architectural knowledge is increasingly important.
Partners accustomed to selling servers, UPS systems, racks and power distribution as relatively discrete infrastructure categories may need to approach AI projects more holistically.
Power density affects distribution, backup requirements, cooling, physical rack design and serviceability, meaning infrastructure decisions become interconnected earlier in the design process. Eaton similarly argues that power and cooling need to be planned together as AI densities rise.
The opportunity, then, isn’t simply selling a different power product. It is helping customers determine when existing AC infrastructure remains sufficient, when rack-level DC makes sense, how to design hybrid environments, and when future workloads justify a more fundamental architectural shift.
Hyperscalers may be setting the direction today. Channel partners should be watching closely for when their customers begin following it.
