- Ensure the main power switch on the PSU is in the 'I' (On) position.
- Verifiqueu que la presa de corrent funciona connectant-hi un altre dispositiu.
- Use the included 24-pin PSU tester to check if the PSU powers on independently.
- Inestabilitat del sistema/aturades aleatòries:
- Ensure all modular cables, especially the 12V-2x6 PCIe cable, are fully seated and properly connected.
- Check for any loose connections to the motherboard, CPU, or graphics card.
- Verify that your system's power requirements do not exceed the PSU's 850W capacity.
- Fan Not Spinning (iCool ON):
- If iCool mode is ON, the fan may not spin at low loads. This is normal operation.
- If the fan does not spin even under load, try switching iCool mode OFF to force continuous fan operation. If it still doesn't spin, contact support.
- Sorolls inusuals:
- Assegureu-vos que no hi hagi cables que obstrueixin el ventilador.
