[SOLVED] Faulty motherboard out from box (New Build)

[dinoomc]

Hi there, I am looking for some advice.

I am building a new pc for my roommate. ( I have built a few systems before this ) After wiring everything and turning the computer I have noticed that the pc does not boot. - no beep codes, nothing at all.

I have tried the following

CMOS reset.
Trying a different psu
Singling out components
Switching ram and adjusting ram sticks
Jumping through mobo.

I have concluded that the motherboard came defective and dead. But does anyone have any suggestions before I go and replace the parts?

Edit:
Components
CPU: Ryzen 3600x
Cooler: Bequiet dark rock 4
RAM: 8x2 DDR4 3000mhz Thermaltake Tough ram
Mobo : MSI Tomahawk Max
GPU: MSI GTX 1660 Super
PSU : 620 W Seasonic 620 Bronze Certified
Storage: Seagate m.2 ssd 1tb

coolness.
try forcing a beep code.
disconnect everything apart from the CPU, keyboard, speaker and GPU. I did not forget RAM, pull the RAM and try to boot the minimum system with no RAM installed.
in my experience if you cannot force a beep code in this way the motherboard is toast.
call MSI and setup a return.
