When Nvidia CEO Jensen Huang energy as the foundational layer of “the largest infrastructure buildout in human history" at Davos earlier this year, he could have been referring to the business that Delta Electronics has spent more than five decades building.
The first wave of AI investment chased chip designers and foundries, with TSMC and Nvidia dominating the headlines. The second wave has expanded to encompass the physical infrastructure that makes large-scale AI deployment possible: the power systems that convert grid electricity into clean energy for GPUs, and the cooling systems that carry away the enormous heat they generate. Delta Electronics, with a portfolio spanning power conversion, distribution, cooling, and software management, has emerged as the company best positioned to capture this shift. Its market capitalization recently surpassed US$100 billion, confirming that the market now recognizes power infrastructure as a first-class AI investment.
Delta began in 1971 as a manufacturer of television power supplies. That humble origin belies the technical sophistication the company would develop over subsequent decades. The core competency established in those early years, converting and managing electrical power with maximum efficiency, has proven extraordinarily valuable as computing power demands have exploded.
The company expanded into cooling solutions in the 1990s, adding fans and precision air conditioners to its portfolio. This diversification created the foundation for Delta's current position as the only Taiwan supplier offering fully integrated power and thermal management systems for AI data centers.
Delta's financial performance reflects the accelerating demand for AI infrastructure. In 2025, consolidated revenue rose nearly 32% year-over-year to approximately US$17.9 billion, driven by surging orders for data center power and cooling equipment. Fourth-quarter revenue alone hit US$5.12 billion, an increase of over 40% from a year earlier.
Delta's competitive advantage lies in its ability to deliver power and thermal management as unified systems rather than discrete components. The company calls this its "grid to chip" vision, and it encompasses the full energy delivery path from utility connection to processor die.
Delta Electronics has pioneered advanced power distribution solutions tailored for AI data centers, including 800V high-voltage direct current (HVDC) rack power shelves that deliver megawatt-scale power with greater than 98% conversion efficiency.
On the thermal side, Delta provides coolant distribution units (CDUs), liquid cooling manifolds, and direct-to-chip solutions. Its liquid-to-liquid cooling systems can provide up to 1,500 kW of cooling capacity, while rack-level CDUs certified for Nvidia's GB200 NVL72 hardware handle the thermal demands of the most power-dense AI configurations available. Delta has also developed power shelves with embedded coolant channels, reflecting the convergence of power and thermal management into a single engineering discipline.
As AI data centers scale up, traditional alternating current (AC) power architectures are hitting their limits. Repeated power conversions, complex distribution hierarchies, and sharply higher cabling and copper usage create efficiency losses that become major bottlenecks in high-density environments where rack-level power has surged from 10-20kW to 60kW, 80kW, and in some cases nearly 100kW.
High-voltage direct current distribution addresses these problems by reducing AC/DC conversions, improving efficiency, and simplifying distribution layers. Nvidia has indicated that as rack-level power requirements continue to scale toward the 200kW range expected with the Vera Rubin platform in 2026, higher-voltage architectures like 800V HVDC will become essential.
Delta is among the leaders in this transition. At the OCP Global Summit in October 2025, Delta showcased complete power solutions for both 800 VDC and ±400 VDC architectures, along with a solid-state transformer that converts medium-voltage AC directly to 800VDC. Industry analysts estimate that Delta commands over 60% market share in AI server power, giving it an outsized role in defining the next generation of data center electrical infrastructure.
In India, Delta inaugurated a LEED Gold-certified headquarters and Global R&D Center in Bengaluru in September 2024, creating capacity for up to 3,000 engineering professionals. The company has expanded its Krishnagiri manufacturing facility in Tamil Nadu with new factory buildings and smart manufacturing lines, positioning itself as a key enabler of India's domestic semiconductor ambitions. In the U.S., Delta is expanding production to align with growing hyperscaler demand and evolving trade policies around supply chain localization.
Delta is positioned to benefit from multiple demand drivers. The Nvidia Rubin ramp in the second half of 2026 will require new power and cooling infrastructure as hyperscalers upgrade to next-generation platforms. Rubin's mandatory liquid cooling requirement and higher power envelopes favor Delta's integrated approach. The company expects a 30% increase in power value per rack for GB300 configurations compared to GB200, establishing a strong foundation for revenue and margin expansion throughout the year.
Delta Electronics' transformation from television power supply manufacturer to AI infrastructure leader exemplifies how technical depth in fundamental technologies can compound over decades into strategic positions of enormous value. TSMC makes the chips. Nvidia designs the architectures. But someone has to deliver megawatts of clean power to the GPU die and carry away the heat. That someone, increasingly, is Delta Electronics.
