The launch of the Seasonic Platinum series has achieved great success last year. The fully modular Platinum-860W and Platinum-1000W power supplies have won numerous accolades and became standards of excellence for the 80 Plus Platinum design throughout the entire industry.This year, by presenting an extended family of the Platinum series, Sea Sonic's strength in innovation once again takes center stage to lead the way towards solutions that require the highest efficiency and top performance. The new lineup of Sea Sonic's Platinum series will span the output range of 400 to 1200 watts. All units of the family come equipped with our patented Fully Modular DC Cable design that maximizes output, ensures the stability of the crucial 12V rail and, at the same time, provides ease of integration and ensures forward compatibility.Sea Sonic's extended Platinum Series, which is currently the most complete 80 PlusR Platinum series available on the market, entails the following products:Sea Sonic's highly efficient power supplies in the Platinum 660 W to 1200 W range are top performers that at lower loads can operate absolute silently in semi-fanless mode. As an additional feature, all these units are equipped with a selector switch that enables users to choose between traditional fan control (S2FC) and semi-fanless mode (S3FC). This sophisticated S3FC design ensures that the fan will only start spinning at loads greater than 30% of the maximum load.All the Seasonic Platinum Series power supplies utilize top quality components, such as gold-plated high current terminals and Japan-sourced 105℃ aluminum electrolytic capacitors, which contribute to high performance, reliability and extended product lifetime. Sea Sonic is committed to high quality and stands behind its products by offering 7 years warranty for all the units in the Platinum series.
