I was building a new computer, some of the parts are used or some of them brand new, but i couldn't manage to pass POST. 
MSI B450M PRO-M2 V2
Ryzen 1600 (12nm)
Apacher Panther 2x8 3000MHz(2133 i am using at stock frequency.)

 

nVidia GTX 680

Thermaltake 700W + SSD

 

This builds works fine but whenever i change the graphics card to GTX780, it doesn't work with it. Motherboard says 1 long 2 short beeps and VGA Light keeps steady.

 

I just changed the cpu with the older Ryzen 1600 (14nm) it works with both GTX 680 and GTX 780.

 

I swapped everything to MSI B350 Tomahawk and same errors with Ryzen 1600 (12nm).

 

By the way i tried every part of this build, they work fine but Ryzen 1600 (12nm).


Don't mind to type everything you know even they are simple, sometimes thinking advanced doesn't solve problems.

Any ideas or known solution for this?

Thanks
