PowerMatrix is a deep-tech startup building highly efficient, compact power supply modules tailored for next-generation AI hardware and data center infrastructure. The company’s core product is a single-stage vertical power delivery solution that converts high-voltage facility power directly to the sub-1V levels required by modern GPUs and processors, bypassing the traditional multi-stage conversion chain. This architecture dramatically reduces energy loss, heat generation, and physical footprint while improving dynamic response—critical for AI accelerators and high-performance computing.
PowerMatrix serves AI chipmakers, data center operators, and hardware innovators in sectors including AI, cloud infrastructure, electric vehicles, drones, and aerospace. It solves the growing bottleneck of power delivery in AI systems, where conventional power supplies waste significant energy and limit performance density. With working prototypes and pilots underway with leading partners, the company is positioned at the inflection point of the AI compute boom, where every watt saved translates into material cost, space, and carbon savings at scale.

PowerMatrix was founded by Borong Hu, a power electronics expert with over a decade of experience in high-efficiency power conversion. He holds a PhD in power electronics from the University of Warwick and completed postdoctoral research at the University of Cambridge, where he published 60+ papers and received the IEEE ECCE William Portnoy Award for outstanding contributions to power electronics. His industry experience includes developing a power converter for the world’s largest wind turbine at GE and leading the power supply team at Bitmain, a major bitcoin mining hardware company.
The idea for PowerMatrix emerged from firsthand exposure to the extreme power demands of high-performance computing and AI hardware. Hu recognized that as AI chips scaled in power (now routinely exceeding 1kW per GPU), traditional multi-stage power delivery architectures were becoming a critical bottleneck—inefficient, bulky, and thermally challenging. PowerMatrix was founded to reimagine power delivery from the ground up, leveraging proprietary circuit topologies, advanced materials, and vertical integration to create a new class of power modules optimized for AI and other cutting-edge applications. Early traction includes functional prototypes and pilot engagements with world-leading partners in AI and data center infrastructure.

Eliminates multiple intermediate conversion stages by converting high-voltage input directly to sub-1V levels right beneath the processor. This reduces energy loss by up to 50% compared to conventional solutions.
Achieves unmatched efficiency and power density by minimizing current loops, using novel magnetic materials, and embedding packaging directly under compute chips, enabling smaller form factors and better thermal performance.
Designed for the rapid load transients of AI accelerators, delivering faster transient response and tighter voltage regulation than legacy VRMs and intermediate bus architectures.
Combines patented circuit topologies, advanced semiconductors, and AI-driven R&D to accelerate design and optimization of power modules for extreme performance requirements.
The company estimates that widespread deployment of its modules could save customers $10B annually, avoid 30 TWh of electricity waste, and cut 100 Mt of CO₂ emissions per year—making it both an economic and climate-critical innovation.

PowerMatrix is riding the convergence of three powerful trends: the explosive growth of AI compute, the physical limits of traditional power delivery, and the urgent need for energy efficiency in data centers. As AI chips push toward multi-kilowatt power levels and data centers consume an ever-larger share of global electricity, the inefficiencies of conventional power supplies are no longer tolerable. PowerMatrix addresses this by rethinking power delivery as a vertical, single-stage system integrated directly with the processor—akin to how advanced packaging has transformed compute.
The timing is critical: hyperscalers and AI hardware makers are now prioritizing power efficiency and density as much as raw compute performance. Regulatory and ESG pressures are also forcing data centers to reduce energy waste and carbon footprints. PowerMatrix’s solution aligns perfectly with these forces, enabling denser racks, lower cooling loads, and reduced capex/opex. Beyond AI, the same architecture can benefit EVs, aerospace, and drones—any application where power, weight, and efficiency are paramount. In doing so, PowerMatrix is helping to define the next generation of power infrastructure for the most demanding technologies.

PowerMatrix is poised to become a foundational enabler of the AI era—not by building chips or software, but by solving the often-overlooked but critical problem of how to deliver power to those chips efficiently and compactly. As AI accelerators continue to scale in power and data centers face hard constraints on energy and space, demand for radical power delivery innovations will only grow. PowerMatrix’s single-stage vertical architecture could become a de facto standard in next-gen AI servers and high-performance systems.
Looking ahead, the company’s path likely includes deeper partnerships with leading AI hardware vendors, expansion into adjacent markets like EVs and aerospace, and potential integration into system-level designs (e.g., co-packaged with GPUs or custom AI chips). For investors and ecosystem players, PowerMatrix represents a rare combination: deep technical moat, massive addressable market, and clear environmental impact. In a world where every watt counts, PowerMatrix isn’t just powering AI hardware—it’s helping to make the AI revolution physically and economically sustainable.
