Seasonic VERTEX GX-850 power supply unit 850 W 20+4 pin ATX ATX Black

80 PLUS GOLD
The Vertex GX Series achieves 80 PLUS Gold certification with its 90 % efficiency at 50 % system load.

ATX 3.0 AND 16-PIN PCIE GEN 5 CABLE (12VHPWR)
Seasonic’s latest Vertex Series is designed and built to power new PC components requiring the new ATX 3.0 and PCIe 5.0 standards.

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.
