PSU Diagnostic Guide

If your system encounters issues and you want to rule out a PSU failure, you can perform this basic test to ensure the unit is functioning correctly.

1. To ensure safety, please turn off the PSU and flip the I/O switch on the back panel to the "O" (OFF) position.
2. Unplug the AC power cord from the PSU.
3. Disconnect all internal cables from the PC components and peripherals.
4. Plug the AC power cord back into the PSU. Ensure the cord is plugged directly into a wall outlet (avoid power strips, extension cords, or splitters for this test).
5. Connect both the 18-pin and 10-pin connectors of the motherboard cable to the PSU side.
6. Set the fan control switch to Normal Mode (S2FC). (In Hybrid or Fanless mode (S3FC), the fan will not spin, making it harder to verify operation).
7. The Paper Clip Test: Using a paper clip or a jumper wire, bridge the specific pins on the 24-pin motherboard connector as shown in the illustration to jump-start the unit.
8. PSU Tester: If your Super Flower PSU included a dedicated tester, plug it into the end of the 24-pin cable. It features a notch for secure alignment.
9. Flip the I/O switch to the "I" (ON) position.
10. Check the Fan: If the PSU fan starts spinning, the unit is likely functioning normally.

Please Note: This is a basic functional test. For precise diagnostics, please contact our RMA department.
