Features: 80 PLUS Gold certified Micro Tolerance Load Regulation (0.5 %) Cable-free Connection Design Premium Hybrid Fan Control - Fanless until 20 % load Multi-GPU setup Gold plated connectors Its ultra-high efficiency and outstanding performance are the fine results of Seasonic's continuous commitment to innovation and advancement. Improved low-load efficiency, highly suppressed ripple noise. The PRIME Gold Series achieves 80 PLUS Gold certification with its 90 % efficiency at 50 % system load. 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. 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. 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. Seasonic's engineers have implemented adesign 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.
