4 FAQs about 400V Industrial Server Racks in Xiong an New Area

Is 400-v DC distribution inevitable?

In this exclusive Q&A, Vicor contends that ±400-V DC power distribution to AI racks in data centers is inevitable. The demand for increased compute density. An evolution to ±400-V DC distribution to next-generation AI/ML supercomputer racks to meet that demand. Challenges and solutions in making the move to ±400-V DC distributed power.

What is Xiong'an New Area?

The Xiong'an New Area has been designed to take on functions transferred from Beijing that are not essential to its role as China's capital. In Xiong'an, dubbed China's "city of the future," sci-tech innovation and industrial development synergistically promote each other.

Should hyperscalers adopt 400-v DC distribution to Next-Generation AI supercomputer racks?

To increase compute density and to deal effectively with the prospect of racks that consume up to 140 kW or more, hyperscalers are now advocating an evolution to ±400-V DC distribution to next-generation AI supercomputer racks.

How much power does an AI rack need?

Assuming 140 kW per AI rack, this is 350 A at 400 V DC and 175 A at 800 V DC. Currents as high as 350 A likely require 500 MCM gauge copper cable (380 A ampacity at 75°C), while current of 175 A likely requires 3/0 AWG copper cable (200 A ampacity at 75°C).
