I'm completely new to mining Monero but I want to give it a try and get more knowledge of hardware. So I got a good price for an Asrock D1800M. It is a BGA Celeron and the system should use around 20W without GPUs.
Is this CPU enough to power up to three AMD RX 480 GPU?
Is PCIe x1 enough for mining with GPUs?
And what power does an RX 480 use while mining?
Thank you very much for reading this and big thanks for every answer!
