Flex Acquires EPC Power for $4.4B to Drive 800V DC Architectures in AI Data Centers

Flex has entered into a definitive agreement to acquire EPC Power for $4.4 billion, incorporating high-voltage power-conversion technology, digital rectifiers, DC-DC converters, and grid-forming systems into its infrastructure portfolio. The deal, slated to close in late 2026 ahead of Flex's planned spin-off of its Cloud and Power Infrastructure business in early 2027, centers on EPC Power's 800V direct current (DC) architecture. This platform connects 800V DC loads directly to utility supplies and energy storage systems, effectively consolidating functions traditionally handled across separate uninterruptible power supply (UPS) systems and complex alternating current (AC) power distribution gear. This transaction highlights how electrical delivery has become the core operational bottleneck for modern AI facilities. Conventional 48V or 400V power delivery topologies require thick copper busbars and suffer significant resistive transmission losses when routing tens of megawatts into dense accelerator rows. By transitioning to 800V DC topologies, data center operators cut the required current for a given power level, reducing conductor weight, mitigating rack-level heat dissipation, and boosting overall Power Usage Effectiveness (PUE). For hyperscale and enterprise operators running high-density clusters, these gains translate directly into higher compute density per square foot. The acquisition reflects a broader architectural convergence where data centers increasingly resemble specialized power plants. As massive training runs and dynamic inference workloads cause instantaneous, megawatt-scale power swings, facilities require advanced grid-forming inverters and solid-state transformers to maintain grid stability and interface seamlessly with on-site battery storage and microgrids. Electrical conversion is no longer an external facilities detail; it is now a strategic, tightly coupled component of the AI compute stack. For DevOps, platform engineers, and data center architects, this shift will require revisiting facility and rack specifications. Moving toward native 800V DC topologies simplifies power conversion stages but demands new hardware certification, updated arc-flash mitigation protocols, and strict adherence to emerging Open Compute Project (OCP) standards. Infrastructure teams planning new capacity or retrofitting existing halls should evaluate the integration of direct DC distribution and solid-state conversion into their thermal and electrical roadmaps.
