Question No Display Output from External GPU

[Test1234321]

Hi everyone,
I’m having a frustrating issue with my PC and would appreciate any help. Here’s my setup and what I’ve tried so far:

After my old PSU exploded, I replaced it with the current MAG A550BN PSU. Since then, my external GPU (ZOTAC GTX 1060) hasn’t been able to output anything to my monitor.

• If I set the external GPU as the primary adapter in the BIOS, its fan spins, but the monitor displays no signal. However, the card doesn’t work at all unless it’s set as the primary display adapter.
• I tested an older GPU, and it has the same issue: fan spins, but no output.
• When I set the integrated GPU as the primary adapter in the BIOS, everything works fine, but I lose the performance of the external GPU.
• I’ve updated the BIOS to the latest version, tried disabling the integrated GPU in the BIOS, and tested different monitors and cables. None of these steps fixed the problem.

The external GPUs are detected in Windows when the integrated GPU is set as primary, and their fans spin as expected. However, there’s still no output from them.

Nothing seams to be damaged. I think it could be a problem in bios setting. If anyone has ideas or has encountered this before, I’d appreciate some guidance.
Thanks in advance!

it is call dedicated gpu, not external gpu
which other gpu did you test with?
try another slot on the motherboard? what is the motherboard brand and model?

how exact did you blowup the old psu?

Have you tried making sure the connectors for power on the graphics card are seated properly?

Sorry i’m not a native speaker. The old psu made 2 boom with a lot of light and some white smoke in the middle of the night while the pc was off since few hours. I think it was a problem with the electrical system of the plug in the wall and not with the PC. The psu doesn’t work since this, but it has no visible damage.
The other GPU is a Radeon RX 460 double. The motherboard is a gigabyte GA-H110M-S2H. No there is no other slots for the GPU.
