Does anyone know what the electricity bill or watts are for a 1500KH/S mining rig?
A rough answer would be about 45$ a month.
A more precise answer can be calculated as follows.
1. Understand the terms. 1 Kwh = 1 kilo-watt hour = 1000 watts for 1 hour
2. Look at your most recent electricity bill. It should state your rate per kwh. (Will assume $0.10)
3. Select the type and quantity of GPUs you want to use. For example 2x R9 280x would give you more or less 1500 KH/s.
4. Find the power consumption (i.e TDP) in watts for your card. The R9 280x consumes about 250 watts.
5. Add about 100 watts for your CPU, harddrive, etc.
6. Total wattage = 100 w + (card wattage * number cards). In this example, 600 w, or 0.6 kw.
7. Calculate costs: Mining hours per day * mining days per month * total kw * rate per kwh.
i.e. 24 * 30 * 0.6 * 0.1 = $43.20 a month
