This 800VDC architecture solves many problems: With a single-step AC/DC conversion, there are fewer transformer losses and a more direct power flow. There is also reduced electrical complexity and maintenance and management needs. . When Flex President Chris Butler started talking about the imminent reality of 1 megawatt (MW) racks in an interview this week, it sounded like an echo. According to Butler, they're coming. . This brings us to the modern day issue, which is the fast-moving rack power densities for accelerated compute platforms like the NVIDIA GB300 NVL72 that runs 72 GPUs in parallel at 142 kW per rack. Power must be transformed from the utility, most likely around 35kV down to 12V into the server. . The electrical appetite of data centers is almost insatiable. A single server rack will require up to 1,000 kilowatts, or 1 megawatt, in the near future.

Are 1 mw racks coming soon?
When Flex President Chris Butler started talking about the imminent reality of 1 megawatt (MW) racks in an interview this week, it sounded like an echo. That's because just two days before LiquidStack's Head of Strategy Angela Taylor mentioned the same thing. According to Butler, they're coming soon.
Cooling systems aren't the only thing that needs to change to enable 1 MW racks. Power supply systems are another critical component. Flex is currently working on 400 volt (V) direct current (DC) systems, and Butler said it's already eyeing 800V DC and even 1500V DC for the future.
The industry responded by scaling rack power from 10 kW to 100 kW. The transition from 48 volts direct current (VDC) to the new +/-400 VDC allows IT racks to scale from 100 kilowatts to 1 megawatt.
The two main power distribution approaches feeding into the servers today are 400V 3 Phase AC and 48 VDC to the rack. Both of these approaches become difficult at 200 kW per rack and impossible at 400 kW per rack, which correlate with the NVIDIA Kyber and NVIDIA Rubin Ultra platforms.
