Flex Acquires EPC Power for $4.4B as AI Compute Drives Shift to 800V DC Power Architecture

What happened: Flex entered into a definitive agreement to acquire EPC Power for $4.4 billion, integrating advanced 800V direct current (DC) power conversion, digital rectifiers, and grid-forming technology into its data center infrastructure business. The acquisition is slated to close in the fourth quarter of 2026, ahead of Flex's plan to spin off its Cloud and Power Infrastructure segment into an independent, publicly traded company in early 2027. EPC Power is projected to generate approximately $800 million in 2026 revenue with strong double-digit growth anticipated for 2027. Why it matters: As accelerator racks surge in density, delivering multi-megawatt capacity to IT rows under legacy 48V or 400V alternating current (AC) topologies imposes prohibitive resistive losses and cable thickness constraints. Transitioning to 800V DC architecture reduces current requirements, mitigates copper volume and thermal dissipation in busways, and eliminates multiple conversion stages between utility inputs and chip-level voltage regulators. For facilities designers and infrastructure engineers, power electronics are evolving from backend mechanical/electrical support systems into strategic throughput enablers that dictate how rapidly compute can scale. Context: Data center operators worldwide are grappling with severe utility interconnection queues, accelerating the deployment of behind-the-meter generation, battery energy storage systems (BESS), and microgrids. EPC Power’s grid-forming inverters and solid-state transformer roadmap allow high-draw facilities to dynamically stabilize local grids and manage volatile peak loads from distributed training runs. Flex’s multi-billion-dollar valuation reflects a broader industry trend where electrical power architecture and advanced packaging command strategic premiums alongside custom silicon and optical fabrics. What it means in practice: Engineering teams planning next-generation cluster expansions should begin evaluating 800V DC distribution paths to simplify substation-to-rack delivery and cut parasitic conversion losses. In practice, this transition requires close alignment between IT hardware vendors, mechanical engineers, and electrical facility teams to navigate non-trivial trade-offs in direct-current circuit protection, safety ratings, and supply chain standardization for specialized power-conversion modules.
