Nvidia Prepares Data Center Industry for 1MW racks

Oct 13, 2025 | Posted by Abdul-Rahman Oladimeji

Nvidia has announced more than a dozen partners as it looks to prepare the data center industry for 800-volt DC power architectures and rack densities of 1MW.

The GPU giant this week said it would unveil specs of the Vera Rubin NVL144 MGX-generation open architecture rack servers.

“Moving to 800VDC infrastructure from traditional 415 or 480 VAC three-phase systems offers increased scalability, improved energy efficiency, reduced materials usage, and higher capacity for performance in data centers,” Nvidia said. “Over 150 percent more power is transmitted through the same copper with 800VDC, eliminating the need for 200-kg copper busbars to feed a single rack.”

CoreWeave, Lambda, Nebius, Oracle Cloud Infrastructure, and Together AI are among the companies designing for 800-volt data centers. Nvidia noted that Foxconn’s 40MW Kaohsiung-1 data center in Taiwan is also using 800VDC.

Nvidia added that the new Vera Rubin NVL144 rack design features 45°C (113°F) liquid cooling, a new liquid-cooled busbar for higher performance, and 20x more energy storage to keep power steady. A central printed circuit board midplane replaces traditional cable-based connections for faster assembly and serviceability

There are 4508 data centers in United States.
