How many kilowatts does a data center rack have?

“Over the last decade, data center rack density has steadily increased from 2-4 kilowatts (kW) per rack to 8-12kW. But in the last two years, driven by AI demand, we've seen densities spike to over 50kW per rack, with some even exceeding 100kW,” says Perkins Liu, senior manager and research analyst at 451 Research.
