Seasonic Focus GX-850 power supply unit 850 W 20+4 pin ATX ATX White
FOCUS GX ATX 3.0
Following the well-established legacy of the Seasonic FOCUS Series, the FOCUS GX Series was upgraded to comply with the ATX 3.0 and PCIe 5.0 standards. Offering a complete range of power supplies ranging from 750 W to 1000 W with in a 140 mm depth, these units will be the perfect allies to power the newest high power graphics cards and processors on the market.
Digital Hybrid Fan Control
The industry’s first, Seasonic patented, advanced three-phased thermal control achieves optimal between silence and cooling. This Digital Hybrid Fan Control functions in three operational stages: Fanless Mode, Silent Mode, and Cooling Mode.
Reduced noise without increase in temperature
Extended fan life due to the reduced number of fan rotations
Optimized heat dissipation at all times
Unsurpassed silent performance in Fanless Mode
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.
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.
