Hi All!

I just set up my first rig with the following items:

GPU: 4x AMD RX 580 ROG-STRIX 8GB
MB:  GIGABYTE 1151 GA-H110-D3A BTC
PSU: EVGA SuperNova GQ 1000W
CPU: Intel Dual Core G4560 BOX
RAM: Kingston 8GB DDR4

My problem is that the rig only boots if I don't plug in any risers... so with the onboard graphics. If I connect just one riser the rig doesn't do anything after power on. Do I need to change anything in the BIOS before I plug in the risers?

On the power side:
Do I need to plug in the two 12V PCIe power connectors on the motherboard, the SATA to 6PIN adapter to the riser AND the 8PIN EVGA to the GPU as well? Am I doing something wrong?

PS.: I tried to chage the riser card as well, no change.

Thank you very much!

Here are my setup images:
