Question PC won't post after new CPU and motherboard.

[mushiwushiwastaken]

Hi!
I bought a new R5 5600 and a Gigabyte B450M S2H but I couldn't get my PC to post. I made sure the bios is updated for Ryzen 5000 series. I tried unplugging all drives, reseating the ram, clearing CMOS, nothing fixed it.
When I turn it on all fans are spinning though, but I noticed my GPU lights don't turn on when it normally does. Unfortunately, this motherboard doesn't have debug LEDs so I don't really know what to do.
All components were working fine on my previous config (i3 12100F, Biostar H610MH)
I was wondering if I have any other options before I send it back, I would like to use this for work.

Specs:
Ryzen 5 5600
Gigabyte B450M S2H
Palit Dual OC RTX 3060
Skihotar 2x8GB DDR4 3200Mhz
FSP HV Pro 85+ 650W
