Clueless on how electricity works, let alone the cost of it....!

Just curious, below are the specs of my setup. Any idea what it would cost to leave running for 12 hours?
Total module power: 3,873 mA +12v / 1,749 mA -12v / 92 mA +5V
The case I have will take up to 8000/3200 mA
The average electricity rate in my area is 19.74¢ per kWh


To calculate the power outlet you have to multiply your current value with the voltage value (you can ignore the minus sign since that's only a polarity specification) and add everything up. Your case consumes about 67.66Watts. I'll round that up to say about 70W just for ease. To know how long you can run your system until you reach 1kWh you take 1000Wh/70W and you come up with about 14.3hours. So you have to invest about 20¢ every 14.3 hours.
To calculate the price of 12 hours simply take 12h*70W=840Wh. And multiply that with the price of one Wh which is 0.01974¢ so you have to pay about 16.6¢ every 12 hours you run your synth.
Hope that helps :)


Fantastic!

Now I know what to tell my wife
