Seasonic Prime Airtouch 850 850w 80 Plus Gold ATX12V Power Supply

The red & black exterior of the PRIME AirTouch houses an innovative Five-Stage Hybrid Fan Controller, which regulates the cooling of the power supply via a button at the back of the power supply. As the user toggles through the five different fan settings, this button houses an LED which will also light up in five different colors correlating to the selected fan mode.
