Overview

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. 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. 

80 PLUS® Gold

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

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.

Benefits

  • 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).

The Fan Control Button

The fan control button can be found on the back of the FOCUS PLUS power supply, next to the power switch. The image here illustrates how to select different fan control modes to suit your need.

DO NOT press the button if you wish to include the Fanless Mode, which means the fan in the power supply will not spin when the power supply is under light loads. Press the button if you wish to have the fan spin at all times, even at lower loads.

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.

Seasonic is known for it's quality and this was no different, came with nice bunch of ties and plenty of cables. Being fully modular it makes life so much easier having only what you need. Cables are pretty flexible, apart from the atx cable which will always be a bit of a pain but suprisingly it's still more flexible on the mobo end.

This is a quiet, well-built, quality PSU. I like the modular cable design. Its early days but I cannot think of any improvements that could be made. Id be interested to see a PSU that has fans that could be controlled by the motherboard fan headers though.

Not the cheapest but one of the best, plenty of cables for most setups and no mustard and ketchup, and very quiet

Very quiet, even with hybrid fan mode off

This PSU replaced a suspect PSU (approx 10 years in service) in my home built desktop machine. This was rebuilt to a lower specification late last year. Have a number of years experience with Seasonic PSUs and have always found them to be reliable, of robust construction and value for money.
