Seasonic is one of the older companies producing consumer power supplies having been founded in 1975 and entering the PC power supply production market in 1980. Seasonic is the OEM and ODM of this unit. During more than 30 years as a company, Seasonic has cultivated lines of power supplies that are today some of the standard-bearers for efficiency and quiet computing. This focus, and its reputation for quality, has led to an explosion in production as Seasonic can be found providing OEM services on various model lines for Antec, XFX, Corsair, PC Power and Cooling, and of course under its Seasonic brand among many more.
