9. Seasonic

Seasonic FOCUS PX-850 Fully Modular PC Power Supply 80PLUS Platinum 850 Watt

Seasonic - Do not press the button if you wish to include the Fanless Mode, which means the fan in the power supply will not spin when the power supply is under light loads. Fluid dynamic fan bearing: high performance fluid dynamic bearing fdb fans are designed to take advantage of the impact absorbance effects of oil. The image here illustrates how to select different fan control modes to suit your need.

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. Hybrid silent fan control: the industry’s first, seasonic patented, advanced three-phased thermal control achieves optimal between silence and cooling. 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.

80 plus platinum: the focus px achieves 80 plUS Platinum certification with its 92 % efficiency at 50 % system load. Press the button if you wish to have the fan spin at all times, even at lower loads. Due to the effortless, quieter rotations and its robust construction, this reliable fan technology also greatly increases the lifespan of the fan. This hybrid silent fan control functions in three operational stages: Fanless Mode, Silent Mode, and Cooling Mode. This breakthrough solution not only lowers the chance of production errors during manual insertion but it also improves output power quality.
