Seasonic's engineers have implemented a design feature, where instead of cables; the back panel and the PCB are connected by a copper plate. This breakthrough solution not only lowers the chance of production errors during manual insertion but it also improves output power quality. Advanced three-phased thermal control achieves optimal between silence and cooling. High-performance fans are designed to take advantage of the impact absorbency effects of oil. They are extremely reliable and generate considerably less operating noise and heat than ball bearing fans. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption.
