I check everything and every pc part is new. PSU is NZXT C850. I sent it back as faulty and yes, the card is defective for the shop too. They said they would send my money back or a new card. Im choose the money now because the price is going down and i search for another 7900XT model.

@tokyo47 Have you made sure your BIOS is up to date? I know their were problems with some motherboards detecting 4090s on certain boards, too. Can look at JayZTwoCents videos to confirm. Does the fans spin when you turn on the system? A lot to unpack here.

Try to check your card on another system with good supply and bios settings ?

Of course verify that each of your 8x connector has 8 pins and is not a 8 plastic connector with 6 pins inside like it can exist like for my modular supply , but they arent in same color .
