How to install your power supply?

  1. View our Installation Guide to see the illustrations of the steps below.
  2. Place the Seasonic power supply into the correct place provided in the computer case and secure it to the back panel with the four mounting screws that were provided in the accessory bag of the packaging.  Do not over tighten the screws.
  3. Depending on the type of your computer case, correct mounting of the power supply in most cases will result in the fan side top cover facing the mainboard. This does not necessarily apply to all types of cases. (How to correctly position the power supply)
  4. Mainboard Connection:
    1. DO NOT force the connector into place; the connectors are “keyed” so they can only fit one way. Make sure the connector lock is secure.
    2. Connect the power supply end of the 24/20 Pin convertible connector to the appropriate receptor on the power supply unit.
    3. Connect the power supply end of the 24/20 Pin convertible connector to the appropriate receptor on the power supply unit.
    4. Connect the +12 V P4 connector and the EPS +12 V connector, if applicable.
    5. If your system requires dual EPS +12V connectors, please connect the 12-pin end of the second CPU 8-pin connector into the appropriate 12-pin receptor on the power supply unit. Then connect the mainboard end of this 8-pin connector to the mainboard.
  5. Check out our video guide on how to connect each connector.
  6. The hybrid fan control selector switch, located on the modular cable panel side of the power supply unit can be set to either “I” - S2FC (Normal Fan Control without Fanless Mode) or “O” - S3FC (Hybrid Silent Fan Control with Fanless Mode).
    1. The Normal Fan Control setting (the “I” position, or when the fan control button is PRESSED) enables the fan to rotate continuously in Silent Mode and Cooling Mode, depending on the system load.
    2. The Hybrid Silent Fan Control setting (the “O” position, or when the fan control button is NOT pressed) enables the power supply to run in Fanless Mode up to 20 % (± 5 %) of the maximum rated load. When the load further increases, the S3FC fan control will keep regulating perfect cooling through the Silent Mode or Cooling Modes.
