Question B450 Tomahawk Max gpu compability

[DebelKon]

Hey guys, silly question. I just bought B450 Tomahawk Max and KFA2 RTX 2060 Super but I think the motherboard does not support this gpu. When I turn the PC on, it pops up a message on my screen: '' DVI No Signal'' I've tried it with the HDMI but it pops up the same message with the difference that this time it says HDMI instead of DVI No Signal. I've checked the RAM and the Power Supply, but the problem can't be from them, they are working pretty fine. Btw I've tried to run the PC with GTX 1050 Ti but the same problem appeard. I've tried it with another Monitor but nothing changed. Any suggestions ?
(P.S. Sorry for my English if I've made some mistakes, it's not my first language after all.)

Did you plug the PSU power connector into the back of the GPU?

Yes, I've plugged all the cables in. I've checked maybe a hundred times if I've done it properly, but I think I did.

Do a CMOS reset, on the motherboard. Also make sure the cables are hooked to the GPU, and not the motherboard.

I've done it plenty of times already, still nothing changes. 🙁 I don't even know what to do anymore...

Make/model of the power supply?

First I was with the LMS Power PSU X750 (750w) then I switched to the Corsair TX850M (850w) still no change at all.
