I'm not sure what's hard to understand from -
I have few PSU that I want to switch from using with Avalon 741 to start mining altcoins.
Since I state I already have PSU & Bitcoin miners I am looking for alternatives coin miner recommendations to use 1600 watt PSU.
You can mine anything you want as long as you have a GPU mining rig or an ASIC that uses less than 1600W connected to your PSU.
