What needs to change to enable 1 mw racks?

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.

How many kilowatts are in a mw?

For context, there are 1,000 kilowatt (kW) in a MW. That means 1MW is a wild leap from the 15 kW less racks that permeate data centers today. It's even a giant jump from the high-performance 40-100 kW rack power levels people initially thought AI would require. But Nvidia roadmap for 2027 includes GPUs that will require 600kW of power per rack.

Will liquidstack's new CDU support 1MW racks?

Cordovil said single-phase direct-to-chip systems – which are currently the most popular and the variant that LiquidStack's new CDU supports – are expected to continue to evolve to meet rising power demands. For now, the expectation seems to be that 1MW racks will be within their scope.

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.
