The Seasonic Prime Ultra Gold's ultra-high efficiency and outstanding performance are the fine results of Seasonic’s continuous commitment to innovation and advancement. An 850W capacity, improved low-load efficiency, highly suppressed ripple noise and a generous 12-year manufacturer’s warranty are just some of the characteristics that set these series apart from other power supplies on the market.
Features
80 PLUS Gold
The PRIME Gold Series achieves 80 PLUS® Gold certification with its 90 % efficiency at 50 % system load.
Micro tolerance load regulation
Seasonic’s latest design keeps the output voltage within a very tight range, achieving under 0.5 % load regulation. This impressive electrical performance and stability makes this power supply an ideal choice for high-performance systems.
Premium hybrid fan control
Seasonic’s vast experience in designing the most silent and efficient power supplies on the market was translated into the development of Hybrid Mode; a state-of-the-art fan control that enables users to keep the overall fan noise at the lowest possible level.
Fluid dynamic fan bearing
High performance Fluid Dynamic Bearing (FDB) fans are designed to take advantage of the impact absorbance 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. Due to the effortless, quieter rotations and its robust construction, this reliable fan technology also greatly increases the lifespan of the fan.
How it works
When the fan shaft rotates, high pressure oil drifts along the grooves of the bearing sleeve to generate a thin layer of lubrication between the bearing faces. As the speed increases, so does dynamic oil pressure and the shaft is lifted from the bearing to create smooth, effortless rotations. The herringbone shape of the groves helps to efficiently channel the lubricant and avert leakage.
Cable-free connection design
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 breakthrough solution not only lowers the chance of production errors during manual insertion but it also improves output power quality.
