does it include cables?

Yes, they are listed in the specifications section: 1 x Main Power (24/20 pins) 1 x CPU (8/4 pins) 2 x PCIe (8/6 pins) 6 x SATA 3 x Peripheral 1 x Floppy

Will this support 8th Gen. Intel processors?

Of course. PSUs from 10 (or more) years ago can support modern processors. PSUs don’t really need compatibility updates to work with new processing technology - they are universally compatible so long as they have the connectors you need and put put out power you need.
