The newly upgraded Seasonic FOCUS GX 650 is the successor to the FOCUS PLUS 650, 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 FOCUS GX 650 by 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 align with the concept of the OneSeasonic Initiative.

About the Seasonic FOCUS GX 650 Power Supply Unit
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).
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.
