The Seasonic Prime 650W Platinum certified power supply is rated to achieve 92% efficiency at 50% system load. This high efficiency ensures that there is less heat wasted during operation, which in turn not only reduces the strain on the system components but it also lowers the costs of electricity for users. An ultra-quiet, 135mm Fluid Dynamic Bearing Fan (regulated by SeasonicÆs proprietary Premium Hybrid Fan Control) delivers excellent airflow with exceptionally low noise levels. This unit is an ideal companion to an office computer or an environment where noise levels need to be at the minimum.Main Features80 Plus® Platinum - The second highest level of efficiency, the less power gets wasted in the form of excess heat. The 80 Plus® Platinum certification guarantees greater than 90%, 92% and 89% efficiency at 20%, 50% and 100% operating loads, respectively. The Seasonic Platinum Series represents the highest level of technology and efficiency achievement of Seasonic during its 40 years of commitment to engineering excellence.Micro Tolerance Load Regulation - Seasonic's latest design keeps the output voltage within a very tight range, achieving under 0.5% (1 % for 1000W and above) load regulation. This impressive electrical performance and stability makes this power supply an ideal choice for high-performance systems.Fluid Dyanamic Fan Bearing (135mm) - 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.
