As part of the One Seasonic Initiative, the Prime TX, Prime PX, and Prime GX series have been introduced as successors to the Seasonic Prime and Prime Ultra series. The Prime series has always demonstrated outstanding performance and has become synonymous with technological excellence and quality over the years. This third generation of the Prime series has been launched not only with a unified naming scheme but also with an updated overall design and connection cables. The Prime Platinum series achieves 80 PLUS Platinum certification with an efficiency of 92% at 50% system load. Seasonic's experience in developing the quietest and most efficient power supplies on the market has been incorporated into the development of the hybrid mode; a state-of-the-art fan control that allows the user to keep fan noise at the lowest possible level.
