Seasonic Focus GX power supply unit 750 W 20+4 pin ATX ATX Black FOCUS-GX-750-V4

The newly upgraded FOCUS PX and GX series are the successors to the FOCUS PLUS Series. which became an instant top seller in... morethe power supply market after its launch in 2017. In 2019. Seasonic engineers have made improvements to the popular series such as removing the inline capacitors on the supplied cables. Besides the small change in the series naming. the PSU housing and its packaging are also updated to be in line with the concept of the OneSeasonic Initiative.S3FC - Fanless until 30 % loadThe industry's first. Seasonic patented. advanced three-phased thermal control achieves optimal between silence and cooling. This Hybrid Silent Fan Control functions in three operational stages: Fanless Mode. Silent Mode. and Cooling Mode.Fluid Dynamic Fan BearingHigh 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.
