About Power Solutions International
Power Solutions International designs and manufactures engines and enclosed power systems. It earns revenue selling emission-certified engines and complete generator packages to original equipment manufacturers and end customers across power systems, industrial, and transportation markets.
Data center power has become the company's defining business. Its enclosed generator systems provide standby and prime power for data centers, and PSI has vertically integrated enclosure manufacturing to expand that capacity. Legacy lines still supply engines for industrial equipment such as forklifts and for transportation applications.
Founded in 1985 and headquartered in Wood Dale, Illinois, PSI employs about 1,000 people, trades on the NASDAQ, and is majority owned by Weichai America, part of China's Weichai Power group. Its products are certified to major emission standards, a longtime differentiator.
Power Solutions International in the AI buildout
Power Solutions International sits in the Power & Energy and Data Centers layers as a generation hardware supplier. Data centers need standby power for reliability and, increasingly, prime on-site generation while grid connections lag, and PSI's enclosed engine and generator systems serve both. That business is now the company's strategic core and largest growth driver, placing it closer to the buildout than most diversified engine makers, though legacy industrial and transportation engines still contribute meaningful revenue.
PSIX is tracked in Power & Energy and Data Centers & Hardware, rated Strategic on the AI Exposure leaderboard.
