1. This miner has 3, 468 Watts, processes 104 Th/s and weighs about 20 pounds. 2. We can also get any other model Whatsminer, just ask 3. If self-hosting, you must have a 220v outlet, as a small step down transformer will not work. If self-hosting, please be aware that these machines are very loud and get very hot. They require significant ventilation, especially the newer models. 4. All new miners come with a 12-month manufacturer's warranty. 5. Shipped from the US.
