The exponential growth of AI workloads is increasing data center power demands. Traditional 54 V in-rack power distribution, designed for kilowatt (KW)-scale racks, isn’t designed to support the megawatt (MW)-scale racks coming soon to modern AI factories. NVIDIA is leading the transition to 800 V HVDC data center power infrastructure to support 1 MW IT…
Copper overload: The physics of using 54 V DC in a single 1 MW rack requires up to 200 kg of copper busbar. The rack busbars alone in a single 1 gigawatt (GW) data center could require up to half a million tons of copper.
May I know how you came to this conclusion? @jwitsoe
1 GW = 1000 MW → 200 kg/MW x 1000 = 200,000 kg = 200 tons.
This is 2,500 times less than your stated figure of “500,000” tons, a number that appears highly unrealistic.
