Seasonic Prime GX

The latest design from Seasonic maintains the output voltage within a very tight range and achieves load regulation below 0.5%. Seasonic's extensive 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 allows users to keep the overall fan noise at the lowest possible level. High-performance fans with fluid dynamic bearings (FDB) are designed to take advantage of the shock-absorbing properties of oil. They are extremely reliable and produce significantly less operational noise and heat compared to ball-bearing fans. The lubrication of the bearing surface reduces friction and vibrations, thereby lowering overall power consumption. Due to the effortless, quieter rotations and robust construction, this reliable fan technology also significantly increases the lifespan of the fan. As the fan shaft rotates, high-pressure oil flows along the grooves of the bearing sleeve to create a thin layer of lubrication between the bearing surfaces. As the speed increases, the dynamic oil pressure rises, lifting the shaft from the bearing to produce smooth, effortless rotations. The herringbone pattern of the grooves helps to efficiently channel the lubricant and prevent leaks. Seasonic's engineers have implemented a new design feature where, instead of cables, the back panel and the PCB (Printed Circuit Board) are connected by a copper plate. This groundbreaking solution not only reduces the likelihood of production errors during manual assembly but also improves the quality of the output performance.
