Topic: Power Consumption Question (Read 713 times)

Yes, the calculator will simply assume that you'll be running the rig 24x7 continuously and will calculate energy usage based on it.

In most cases electricity companies charge you based on kWh - which is charge for running a 1 kW of power for 1 hour.
So lets assume your rig consumes 1000 watts. That's 1 kW. So if you run it for 1 hour, that's 1 kWh.
Now if your electricity charges you 20 cents for 1 kWh, your rig is costing you 20 cents per hour - that's 4.8 dollars per day.

I hope it makes it easier for you.

Correct.


No problem.  You're not the only person to be confused by this.  For some reason people understand energy and power when they are talking about calories, horsepower, BTUs, etc, but as soon as they start talking about electricity they get confused. 

Ah Ha, but I get it now! I am an old grease monkey, so it made it clear!

So, basically, the rig would be running at 850 watts, so when these calculators ask for the power input, I just put 850 in and I'm good. So, if you had 2 rigs, same specs, it would be 1700 watts, 3= 2550 watts, etc....?

I am not trying to mine, but this is driving me nuts... tx again for the help

Watts is a unit of power, not a unit of energy.

Your question: "does that mean that the rig uses 850 watts of electricity per second? per hour? per 24 hour period?"

Is a bit like asking about your 285 peak horsepower vehicle, "does that mean that if I run the vehicle continuously at peak horsepower it uses 285 horsepower per second? per hour? per 24 hour period?"

For some reason the "horsepower" statement clearly sounds wrong, but people always seem to get confused about the power when the "watt" unit is used.


Now, when power is supplied for a period of time, you use up energy.  Therefore an 850 watt unit that runs for 1 hour will use up 850 watt hours of energy (or 0.85 kilowatt hours).  Your electric bill is almost certainly using the kilowatt hour unit of measurement.

Just like vehicle will use up a certain amount of fuel when you operate it at a particular horsepower for a specified unit of time (volume of fuel containing a certain amount of available energy).  So if you run your 285 peak horsepower vehicle at peak horsepower continuously for an hour you will use up some number of gallons of fuel.

Run the vehicle for 10 hours, and you'll use up 10 times as much fuel.

Run the electric equipment for 10 hours, and you'll use up 10 times as much electricity (8.5 kilowatt hours).

This may seem retarded and actually probably is, but How does power consumption work with these mining rigs? I see them listed as .65-.85 watts per gh....

Now lets assume, for the sake of my slow working brain today, that it is a steady .85 watts per gh and the rig is 1 th/s. so that's 850 watts, correct?

okay, now does that mean that the rig uses 850 watts of electricity per second? per hour? per 24 hour period?

Being curious, I plugged some numbers into one of those calculators and it asked for the power consumption figures and i realized that i have no idea for the time frame they mean. Thats when i realized that i couldn't do it for my refrigerator either! Thats when I realized that I have no concept of electricity really....

So, I looked at my electricity bill from last month and have become even more confused....lol. So, here I am, oh wise electricity wizards of the forum, please explain this to me so i can go back to work doing something i actually understand.

Thanks
