PSU Troubleshooting Checklist

If your PSU is installed correctly but the system still fails to power on, please check the following steps:

• Verify the AC power cord is firmly seated in the wall outlet and the PSU.
• Re-check all internal connectors (Motherboard, CPU, GPU) to ensure they are securely fixed in place.
• Ensure the wall outlet is powered.
• Confirm the I/O switch on the back of the PSU is in the "I" (ON) position.
• To Reset the PSU: Flip the switch to "O," wait for 30 seconds, and then flip it back to "I." If the issue persists, perform the "Paper Clip Test" mentioned in the Quick Start Guide above.
