I’ve had this from new, purchased early this year. Only selling due to upgrading mining rig. Has been working perfectly, and has never been overlocked or had additional software. Comes in original packaging. Can assist if you need help setting up. Any questions, happy to help. Power consumption - 3500w. When purchased, it came with a European plug. I can fit a 240v, 16amp plug top on if you require it. (Free of charge). Due to the nature of bitcoin and the mining network, I’m afraid I cannot accept returns.
