Flex has agreed to acquire power conversion equipment manufacturer EPC Power for $4.4 billion to secure its 800V high-voltage direct current (HVDC) architecture. This strategic move highlights the critical technical leap towards high-voltage distribution required to support the massive power demands of 1 MW AI server racks.
Overview of the Strategic Acquisition
In a landmark move underscoring the escalating power requirements of artificial intelligence infrastructure, Flex has agreed to acquire power conversion equipment manufacturer EPC Power Corp. for $4.4 billion. The transaction, which both companies expect to close before the end of 2026, represents a critical strategic alignment. Flex is securing EPC Power’s advanced 800-volt high-voltage direct current (HVDC) architecture, a technological standard increasingly demanded by next-generation AI data centers to support massive computational loads.
Technical Details: The Shift to 800V HVDC Architecture
The acquisition highlights a fundamental technical leap in data center power distribution. Traditional 48-54V distribution within server racks becomes entirely unfeasible at the extreme densities required by modern AI workloads. For context, a single 1 MW rack operating at traditional voltages can require up to 200 kg of copper busbars, while a 1 GW data center could demand hundreds of thousands of tons of the metal.
Raising the distribution voltage to 800V DC drastically reduces the current required to transport the same amount of power. According to the roadmap defined by Nvidia at GTC 2025 for racks already exceeding 200 kW, this architectural shift cuts copper requirements by up to 45%. Furthermore, the 800V standard eliminates multiple AC/DC and DC/DC conversion stages, yielding efficiency improvements of up to 5% and significantly reducing ongoing maintenance requirements.
Core Technologies: Digital Rectifiers and Solid-State Transformers
EPC Power brings a highly specialized portfolio of software-controlled power conversion equipment designed specifically for data centers, large-scale storage, and microgrids. The centerpiece of the acquired 800V architecture includes:
- Digital Rectifiers: Advanced software-controlled units that efficiently convert AC to high-voltage DC, replacing legacy passive components.
- Solid-State Transformers: High-frequency, power-electronic-based transformers that offer superior control, reduced footprint, and higher efficiency compared to conventional passive transformers.
- Agile Grid Forming Platform: A specialized system engineered to maintain grid stability in hyperscale demand scenarios, crucial as AI data centers become massive loads affecting local grid operations.
Financial Metrics and Corporate Integration
Upon closing, EPC Power will be fully integrated into Flex’s Cloud and Energy Infrastructure segment. The acquired company is projecting revenues close to $800 million for the current year. Flex anticipates robust expansion within this specific segment, forecasting growth of around 40% by 2027.
This acquisition follows a major corporate restructuring announced by Flex in May, which involved the spin-off of the Cloud and Energy Infrastructure unit as an independent, publicly traded company. That newly independent entity is explicitly focused on providing high-density digital and electrical infrastructure tailored for data centers and utilities, making the integration of EPC Power a perfect strategic fit.
Implications for AI Data Center Infrastructure
The $4.4 billion deal is part of a broader, aggressive consolidation strategy within the AI electrical supply chain. In July, Flex announced a strategic alliance with Cerebras Systems to multiply the production of its CS-3 accelerators sevenfold before the end of the year, securing the compute side of the equation.
On the power infrastructure side, EPC Power recently opened a massive 167,000-square-foot manufacturing plant in South Carolina dedicated to its M and Mrack series inverters. This facility possesses the capacity to triple the company's production output, ensuring that the physical supply of 800V power conversion equipment can keep pace with the breakneck deployment of 1 MW AI server racks.
Future Outlook and Industry Consolidation
EPC Power’s rapid scaling has been heavily supported by previous backing from Goldman Sachs Alternatives and Cleanhill Partners, which allowed the manufacturer to nearly tenfold its manufacturing capacity over the past four years. This financial and operational consolidation has firmly positioned the company as a key supplier in the transition to the electrical architecture required by next-generation AI computing.
Ultimately, Flex’s acquisition of EPC Power secures its position at the forefront of the AI infrastructure boom. By internalizing the critical 800V HVDC technology, Flex ensures it can deliver the high-density, highly efficient power solutions that hyperscalers and AI developers require to push the boundaries of computational performance without being constrained by the physical and electrical limits of legacy data center designs.
