I have 3 different GPU rx570 vega56 and rx470. attempting to use them but the vega wont hash my power supply is 1600 so I ruled that out idk what im doing wrong lol.

try to start the miner twice. Once for the old gpus and once for vega. Mixing old and new gpus is not possible within the same miner.
