It's not happy **[The Register](https://daily.dev/sources/theregister)** · 8 min read · 0 upvotes · 0 comments ## Summary AI workloads like the Nvidia GB200 NVL72 require 120–192 kW per rack, far exceeding what traditional 48V datacenter power architectures can efficiently handle. The core problem is Joule resistive loss: at 48V, delivering hundreds of kilowatts requires thousands of amperes, causing massive copper busbars, heat buildup, and efficiency losses. Moving to 800V DC distribution reduces current by roughly 16x, cutting resistive losses by orders of magnitude and enabling up to 45% copper reduction. The industry is transitioning toward HVDC architectures where AC is converted to 800VDC at the facility perimeter and distributed throughout. New power electronics using GaN and SiC semiconductors handle the step-down to chip-level voltages. Transient load spikes from synchronized GPU operations add further complexity, requiring integrated energy storage. Companies like Eaton, Vertiv, and Delta are already developing 800V-compatible hardware as the industry moves beyond ORv3 limits. ## Full article daily.dev links to this article rather than hosting it.
