Question ASUS TUF Gaming A620M-PLUS WiFi

[Synammon]

I need some help! I have built up my new system. It is an ASUS TUF Gaming A620M-PLUS Wifi board with a Ryzen 9 9950X CPU. No matter what I do, I am unable to get video. I've tried with my graphics card and on board video. I've flashed the BIOS to the latest version. According to the specifications on ASUS's web site my CPU and RAM are supported. The Q-LED Core is solid colour with no flashing. Any thoughts on getting the video to work?

Try using a different HDMI/Display port cable or a different monitor if you have one available.

Have tried all ports, different cables and both monitors in every possible combination.

What would happen if my power supply did not have enough juice to power my system? Would it possibly have the effect I'm currently facing?
