Hi,
It's my first built and I can't get GPUs going... (4x RX580 Red Devil 8GB) GPUs are connected to risers (ver 006) and risers to power supply (SATA). GPUs have both 6 pin and 8 pin slots I have tried each and both at the same time (2x 6+2) and (always 8pin to power supply).
Motherboard Gigabyte ...
