Question Motherboard won't POST ?

[Nxt a Bot]

All of my components power on and my gpu fans spin but I get no signal at all 🙁 My motherboard boot light will stay on until I plug in my usb drive but I still get no POST.
I've reset CMOS and everything but nothing seems to fix it. I'm convinced either my mobo has something wrong with it or my GPU is toast ?

MSI MAG a520M Vector WiFi
16GB 3200MHz Crucial Ballistix
Crucial P2 M.2 SSD
Powercolor Red Devil RX 570
AMD Ryzen 5 3600

I'd appreciate any help!

There's an 8-pin power connector on the top corner of this graphics card --- you've connected this to the PSU ?

Yep everything necessary was plugged in, and after troubleshooting all day and searching the internet I found out someone had a similar problem and they had to Rma their board
