Seasonic Focus GX

The newly upgraded FOCUS PX and GX series are the successor to the FOCUS PLUS Series, which became an instant the top seller in the power supply market after its launch in 2017. In 2019, Seasonic engineers have made improvements on the popular series, removing the inline capacitors on the supplied cables.

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. This breakthrough solution not only lowers the chance of production errors during manual insertion but it also improves output power quality.

Hybrid silent fan control

The 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.


  • 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.

Additionally, there is a switch at the back of the power supply which allows users to customize their cooling needs by selecting between the Seasonic S2FC (fan control without Fanless Mode) and the S3FC (fan control including 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.


The FOCUS GX achieves 80 PLUS®Gold certification with its 90 % efficiency at 50 % system load.

Bruker denne i NAS i et Fractal Design Node 304 Mini-ITX-kabinett. Hører ikke strømforsyninga. Hovedkortet er et ASRock J5040-ITX, kunne sikkert klart seg med mindre strømforsyning, men denne har god kvalitet. Fornøyd med kjøpet. Läs mer

Valgte denne forøvrig fordi det er en kvalitets strømforsyning til en rimelig penge. Angrer ikke ett sekund. Läs mer
