• Product: Switching Power Supply

• Model name: Please refer to the rating label on the product.

• Contact: www.seasonic.com/contact-us BUMWHGUD3BWThe drawings illustrate a fully modular PSU with a fan control switch and a Power Supply Tester; the features and accessories of your PSU might be dierent. 2.1. Plug the AC power cord into the PSU. Make sure that the AC power is coming directly from the wall outlet. 2.3. If your power supply features a fan control switch, set it to “Normal” Mode*.
• In Hybrid or Fanless Mode (S³FC) the fan will not turn. It is recommended to use a high quality surge protector to protect the PSU and the system. ** If you do not have a power supply tester, refer to the paper clip method described below. 2.2. Connect both the 18-pin and 10-pin connectors of the motherboard cable to the PSU. 2.4. If you have a Power Supply Tester**, attach it to the 24-pin motherboard connector. There is a notch on the Tester that helps to make a perfect fit with the 24-pin connector. 2.5. (Optional) For testing a Fanless PSU or a PSU without the fan control switch, attach an external fan or LED light using a Molex cable to the PSU. 2.6. Turn on the power supply by setting the I/O switch to the “I” (ON) position. If the power supply fan starts spinning (or the externally attached LED light turns on), then your PSU is working.

2. Test your Seasonic PSU before installation

Paper clip method3.3. Top of the case 3.2. Flat Desktop-, SFX- or ITX systems Seasonic recommends the PSU to be mounted with its ventilation top cover facing DOWNWARD. In general, it is recommended to mount the PSU with the ventilation top cover facing the motherboard. Due to the dierent varieties of case layouts, however, please also consult the case manufacturer's instruction manual for more information. 3.1. Bottom of the case The fan control setting determines the optimal PSU placement. Fanless PSU The PSU must be mounted into the computer case with the ventilation top cover facing UPWARD.

3. Position your PSU

In “Normal” mode Although the direction of mounting is optional, it is not recommended to install the PSU with the ventilation top cover facing downward if there are no ventilation holes on the bottom of the case. There should always be enough clearance left between the PSU and the bottom case panel. In “Hybrid” mode Seasonic recommends to install your PSU with ventilation top cover facing UPWARD, towards the direction of the motherboard. This will ensure natural heat dissipation. To learn about the ventilation of your computer case, please refer to the case manufacturer’s instruction manual.3.3. Top of the case Mount the power supply with the ventilation top cover facing UPWARD only if there is enough space (at least 5 cm / 2 inches) available between the PSU ventilation top cover and the metal plate of the case, and only if the case has a ventilation panel on top. 4.1. Secure all 4 mounting screws. 4.2. Make sure the PSU power switch is in the “O” (OFF) position. 4.3. Select the fan control type if your PSU has this option.
