550 Watts is cutting it close. 600 Watts would be better. But being so close, you should at least be able to POST to UEFI. The 600 Watts only is needed when you kick it into high gear for gaming and such.

Do you have the necessary PCIe cables hooked up properly? There may not be enough power to power the graphics card.

Plus, what make and model PSU? If it's old, or a generic enough, it might not even supply 450 Watts reliably.

Also try resetting the UEFI by pulling the CMOS jumper on the board.

Hey sorry for late answer , my PSU is Corsair VS550 white with 550W and sadly I don’t have the old GPU in order to check it but right now when I plug my monitor into the MOBO I actually can get a display so do you think it’s posible that my problem is that my GPU isn’t getting enough power ? I’m sure I plugged the pcie power plugged in correctly but still no image with the GPU

Ok then, what is your old GPU?
For some motherboard you need to clear the cmos first before installing new GPU.

Maybe you can try to clear the cmos first, read your motherboard's manual, there is an explanation on how to clear cmos on your motherboard's manual.
