I recently upgraded my GPU from a 4070 to a 5080 RTX and changed some fans. Now when I try to power on my PC, the RGB lights flash for just a moment and then it goes dead. It feels like it's completely unresponsive. Could it be an issue with my power supply? I'm currently using an 850W PSU.

Did you connect the power adapter that came with the 5080? It needs extra connectors since it draws more power than the older models.
It might be the power supply unit (PSU) not being strong enough. Make sure your PSU is sufficient to handle the new GPU's requirements.
It could also be a compatibility issue. If you still have your old GPU, try putting it back in to see if the system stays powered on.
