i have tryed a ryzen 3 1200 and a ryzen 2600 in the board, two differnt psu, every ram slot, clearing the cosmos
I have also tried with different gpus
when i put power to the board all the rgb on the bord flashes for a split second, some times red some times white, tho every time still red cpu led

If you've already tried breadboarding the system outside of the case and are sure you have all the correct powersupply cables installed into the correct locations (mainly the 24pin plus the 8pin CPU/EPS) then it would be a motherboard issue.
