Question RTX 3060Ti won’t post

[patrikman6]

I got my rtx 3060ti today. I uninstalled gpu drivers with DDU. Then i put rtx in pc and it simply doesn’t work. White light on the gpu comes on but no fans nd no display. I had a gigabyte p450b PSU so I thought that was the problem. I went to buy a 750w psu and it still doesn’t work. When i switch the 3060 for my old card (rx460 strix) it works. What do I do? Please help me

Are you plugging every PCIE power cable to the gpu? If yes, are you by any chance daisy chaning or using adapters?
