For over two decades, companies under the Unified Power brand have been providing companies across the country with affordable and reliable UPS equipment, batteries and maintenance service.

Unified Power provides uninterruptible power supply (UPS) equipment and service maintenance to companies across the country. We offer sensible power solutions that are customized to fit the needs of every business.

The Unified Power brand began in January 2011 when Pfingsten Partners purchased On Computer Services; a national critical power service company based in Terrell, TX.  Pfingsten’s vision was to bring together the nation’s best critical power services companies under one unified brand.

  • On Computer Services, Terrell, TX (January 2011)

The Unified Power goal is to bring Advanced Service, Sales, and Testing capabilities together to become the Premier Independent Power in North America. The strategy has been well received by the market. Today, Unified Power is the premier national service provider to more than 2,000 customers, employs service and support staff across the nation, and continues to achieve double-digit growth; all while maintaining a world-class service quality rating from its clients.
