Mining PSU (power supply) Buying Guide | NiceHash

Keep the 1.25 coefficient in mind when reading forward. We used it earlier for calculating PSU wattage. For example, PSU with 80% efficiency will draw 1000W of power from the wall socket but will forward only 800W of power to the computer. This means that 200W of energy is wasted in the conversion process. There are different efficiency ratings.
