TechPowerUp reports the Seasonic Prime AirTouch power supply will hit the market around mid-January 2019. This unit was first shown off to the public at CES 2017 and it's unknown why it faced such a long delay. The special feature of the Prime AirTouch is that it offers users some control over the fan, its rear has a round button that lets you switch between five fan curves:
The fan-control button is embedded with an RGB LED that indicates the active curve. The first curve, called "Silent" (white), kills the fan when the load is below 40%, runs the fan whisper-quiet between 40-80% load, and spools up above 80%. The second curve, called "Low" (blue), runs the fan whisper-quiet up to 60% load, and spools it up from there. The "Medium" (green) curve runs the fan at moderate speeds and caps its speed to 65% beyond 80% load. The "High" (amber) curve maintains moderate speeds up to 80% load, beyond which the maximum fan-speed is capped at 80%. The "Turbo" (red) mode ignores all parameters and simply runs the fan at 100% speed.
The Prime AirTouch features a 12-year warranty. The first model will be an 850W unit (SSR-850GD-AT) with a MSRP of $160.
