so i'm getting an rx card and a decent 450-650w PSU, but the rest of the system i'm thinking about buying a used and old PC, can any mobo power and read my GPU or are there any specific requirements? I'm aiming at total price of about 350 with rx480 a bit more maybe.
A mobo slot with more PCIe slots is recommended for future expansions, z270's are widely used as it can also be resell when mining is not already profitable and decided to give up digging. Also I think 650w would not suffice if you want to expand later on.
