Fluid Dynamic Bearing Fan

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.

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.

Is this really a SSR-850PD (V2) or a prime PX-850? The PX replaced the 850PD in Sept of 2019. The PX has 6 peripheral ports while the 850PD has 5.
Asked by: tom
This model would have 5 x 4-Pin Peripheral / Molex ports.
