Hello @akliiiim 

Thank you for reaching out to us. We apologize for the delayed response due to a public holiday in our region and any inconvenience this may have caused.
Could you please clarify if the issue you are encountering involves being able to boot with display, but unable to detect the RTX 5080 GPU in Device Manager, or if the system fails to display anything after booting, with the VGA Q-LED indicator solid? Additionally, are you using BIOS version 3067 or 3201?
If the issue is the former, could you provide the full model number of your RTX 5080, as well as the driver and VBIOS versions? After clearing CMOS with no manual BIOS settings applied, does the issue still persist?
For troubleshooting, please refer to the guidelines provided in the [Graphics card] Troubleshooting for no display or abnormality on the monitor.

Thank you.

Check whether the 12VHPWR power cable is correctly and completely plugged into the GPU.
I have already read reports where the Nvidia adapter 12VHPWR was used on PCIE 6+2 and the plug could only be fully inserted with a lot of effort.

Therefore, check that it is correctly and completely seated.
