Cable-Free Connection Design: Seasonic’s engineers have developed a new design feature, where instead of cables, the back panel and the PCB (Printed Circuit Board) are connected via a copper plate. This solution not only lowers the chance of production errors, but also improves output power quality.

Hybrid Silent Fan Control An industry 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.

Fan Control Button: The fan control button can be found on the back of the FOCUS PLUS power supply, next to the power switch. Don't press the fan control button if you want to enable fanless mode, which means the fan in the power supply will not spin when the power supply is under light loads. Press the button in if you wish to have the fan spin at all times, even at lower loads.
