5. Seasonic Focus GX-750 V4 750W ATX3.0 black

The newly upgraded FOCUS PX and GX series are the successors to the FOCUS PLUS series, which became an instant top seller in the power supply market after its launch in 2017. In 2019, Seasonic engineers 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 have also been updated to align with the concept of the OneSeasonic Initiative.

S3FC - Fanless until 30% load
The industry’s first, Seasonic patented, advanced three-phased thermal control achieves an optimal balance between silence and cooling. This Hybrid Silent Fan Control functions in three operational stages: Fanless Mode, Silent Mode, and Cooling 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, thereby lowering 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 grooves helps to efficiently channel the lubricant and avert leakage. 

6. be quiet! Straight Power 12 Platinum

The Straight Power 12 Platinum sets standards for whisper-quiet systems without making any compromises in power supply. The 80 Plus Platinum certification demonstrates a focus on efficiency of up to 93.9% in the latest generation of the Straight Power series.
