 I build my pc about a week ago and everything was working great. I shut it down completely after every use. Today when I went to power up, the PSU made a click and nothing turned on. I know it's delivering power because the MB's RGB lights up before and after the click. I ended up doing a bunch of trouble shooting, connecting and disconnecting, reseating cables, ram checks. Finally I got to the GPU, switched it out for my old one and everything works fine now.. so then I put the new one back in, same click no power. Now I've been looking and people are saying it's the power supply that can't supply enough power, my argument there is I've ran it perfectly for 1 week, plus cpu isn't power hungry and I only run m.2's. So is there another step I should take or try? Or is this what I think it is, and I got a defective GPU?

Its likely a defective GPU, although it might be worth trying the gpu in a different pcie slot and/or system to verify.

Its a mini ITX board so it only has the one slot, I also think its defective. Just wanted someone's input/POV incase I've missed something. Thanks !

Just had a look at the PSU tier list and it seems the EVGA GA PSUs have had tripping issues with high transient power draw GPUs (like the 6900XT). So it may be worth swapping that PSU out to prevent future problems.
