Seasonic’s New Flagship PSUs: Seasonic Prime Series

January 11, 2016

During the past forty years Sea Sonic has never stopped setting new industry standards. Its continuous focus on innovation and perfecting power supply design has made Sea Sonic the leader in power supply design and manufacturing.

Like many times before, Seasonic has again arrived at a major breakthrough and it is proud to announce its latest innovation:

the PRIME Series.

Initially, our engineers have set out to create the quietest active cooling power supplies. The creation of the PRIME Series is a renewed testimony of Sea Sonic’s determination to push the limits of power supply design on every aspect. This elegant-looking, exclusive lineup of new products will include 80 PLUS® Titanium- and Platinum-rated units in the range of 550 W to 1200 W, with excellent electrical characteristics, top-level components and fully modular cabling.

The culmination of the PRIME Series is the result of Sea Sonic’s close collaboration with graphics card manufacturers and suppliers during product development. Undoubtedly, the electrical performance of the series is unsurpassed by any analog power supply on the market today. Seasonic PRIME Series power supplies are made with the best quality components, employ an innovative circuit design, and go through rigorous testing to ensure each unit’s amazing load regulation, performance and efficiency. Clean power and prolonged hold-up time (that doubles the current industry standard) are the main characteristics for the ultimate stable performance of the PRIME series power supplies. Sea Sonic strives for the utmost customer satisfaction by demonstrating its commitment to reliable quality with a ten-year manufacturer’s warranty.
