(First of all, excuse my poor english language skills) 

 

My brother wanted a new pc, which I have assembled. And it don't want to start. 

 

The mainboard LED's are off.

I already rebuild it to make shure everything is ok, but it still don't do anything. 

 

[His hardware:] 

Ryzen 2700

MSI x470 Gaming Pro

16GB HyperX DDR4

XFX 5700XT

 

Try checking if the RAM or CPU are compatible with the motherboard you have as the MSI x470 gaming pro only supports 1st, 2nd and 3rd Gen AMD® Ryzen™/ Ryzen™ with Radeon™ Vega Graphics / 2nd Gen AMD® Ryzen™ with Radeon™ Graphics and Athlon™ with Radeon™ Vega Graphics Desktop Processors for Socket AM4

Did you check that all the power cables are seated properly?  The 8 pin and 24 pin at the board and PSU?

Yes

remove the front panel cables, use a piece of metal and short the power pins. See if it works.
