Question PC wont boot at all!

[DEMIG0D]

Nothing happens when I try to start it. Ive checked to see everything being connected correctly, Ive tried booting with a screwdriver instead of case button, ive cleared cmos and i even bought a second psu after a technician told that the psu was the problem. None of the ez Debug leds light up. The only thing lighting up is the ethernet led when i connect the cable. Is the mobo the problem or the second psu happens to be bad too or sth else?

mobo: msu mag tomahawk z790 wifi
psu: Asus rog strix 850w
CPU : i7 13700k
GPU: 4070 gigabyte gaming
RAM: Corsair vengeance ddr5
ssd: samsung 980
case: lian li 216

Has this system ever worked? Or, did you just assemble?

Also, did you try with the 4070 removed and just tried with the integrated video adapter?

Every part is new, never worked before. I tried with the gpu removed, I also tried to boot it outside of the case. No response. It seems kinda clear the mobo is dead i guess

Inspect the CPU socket for damaged or missing pins. Also, make sure your memory is fully seated in the slots.

No pins seem damaged. But wouldnt the "ez debug" leds light up if there was a problem with either the cpu or ram?
