Delta Electronics, Inc.
Delta Electronics makes power supplies, fans, and electronic components that keep everything from phone chargers to data centers running efficiently.
Delta Electronics is a Taiwanese company that makes the parts and power systems behind a lot of things you use every day without noticing. Its biggest business is power supplies — the bricks and internal units that turn electricity from a wall socket into the clean, steady voltage that computers, servers, and factory machines need. It also makes cooling fans and thermal systems that keep electronics from overheating, plus industrial automation gear and components for electric vehicles.
The company's bread and butter is selling to other businesses, not consumers. Its customers include the big server makers, networking companies, and industrial equipment builders, and increasingly the cloud giants building massive data centers. That last group matters a lot right now: as AI workloads explode, data centers need more power and more cooling, and Delta sells both. It builds power shelves and liquid-cooling systems for AI servers, which has turned it into a quiet beneficiary of the AI boom and pushed its revenue to record levels in recent years. Delta got its start in 1971 making parts for televisions, then grew into a global supplier of power and thermal products. One thing that sets it apart is a serious push into energy-saving technology — its products are designed to waste less electricity, and it has built a big business in things like solar inverters and EV charging. It also owns the brand that makes the chargers and power adapters many people recognize, though the industrial side is where most of the money comes from.
Its strengths are scale, engineering, and deep relationships with the world's biggest tech manufacturers. The risk is that it lives inside other companies' supply chains, so a slowdown in servers, PCs, or industrial spending hits it directly. Competition is fierce, especially from lower-cost rivals, and power supplies are not a business with much pricing power when demand cools. Still, Delta has earned a reputation as the reliable, high-quality option, and it pays shareholders a steady dividend while plowing money into factories and research to stay ahead on efficiency.

BIG PICTURE
Almost 60% of Delta's sales now come from AI data centers
- 60% Revenue from AI and data center products
- 40% Everything else Delta sells
A few years ago, AI and data center gear made up only 20% to 30% of Delta's revenue. The company's chief executive now puts that share near 55% to 60%, as AI racks that once drew 15 to 20 kilowatts of power need more than 300. Delta sells the power supplies and cooling systems that keep those racks running, so each denser rack means more money per unit. Source: Hoonsmart, data from 2026
Timeline
A Small Factory Making TV Parts
In 1971, Bruce Cheng started Delta with just fifteen people in a small factory. They made coils for televisions and other small electronic parts, the kind of unglamorous components that every TV needed but nobody noticed. It was a modest start, but it planted the seed for a company that would one day power the world's computers and data centers.
Delta Gets Its Official Name
A few years later, the company registered its formal name, Delta Electronics Industrial Co., Ltd. It sounds like a small paperwork step, but it marked the moment the little workshop became a real company with a legal identity of its own.
The Power Supply Bet
Then came the decision that changed everything. Delta entered the personal computer market and began mass-producing switching power supplies — the boxes inside computers that turn wall electricity into the clean, steady power the chips need. This became Delta's core business, and it made the company the global leader in the field.
Going Public and Spinning Into Fans
In 1988, Delta listed on the Taiwan Stock Exchange, giving it public money to grow. That same year it started mass-producing brushless fans for cooling electronics — a side bet that would quietly grow into the world's number one position in that category.
A Factory in Dongguan
Delta opened its first plant in mainland China, in Dongguan, and set up a Shanghai arm to develop the China market. This was the company planting roots in the place that would become the world's factory, putting it close to where electronics were being made.
Buying a Century-Old European Power Firm
Delta acquired ASCOM Energy Systems, a European telecom power company with more than a century of history. This brought telecom power know-how and a European base, pushing Delta beyond computer parts into the business of energy systems.
A New Team Takes Over
A new management team took charge, with founder Bruce Cheng becoming Honorary Chairman and Ping Cheng becoming CEO. The new boss drove a shift from simply selling components to selling complete solutions — a change in how Delta saw itself.
Delta Buys Eltek
Delta acquired Eltek, a leading provider of telecom power and power for factories and data centers. This strengthened Delta's grip on telecom and data center power around the world — exactly the markets that would soon explode.
Ping Cheng Becomes Chairman
Chairman Hai Ying-jun handed over the role, and Ping Cheng became Chairman while staying CEO. It was a sign that Delta had built a mature, orderly way of passing leadership from one generation to the next.
The AI Power Boom
Then the market woke up to what Delta had become. Its stock climbed more than four times in a year, making it Taiwan's third-largest company, as international investors re-rated it as an AI power infrastructure play. Delta pushed beyond the white-space power it already sold for servers into grey-space power distribution, taking on Vertiv, and positioned itself for Nvidia's coming shift to high-voltage DC power — the next growth engine.
