    @CoinBuster You'd need a Watt meter like a kill-a-watt

    That will give you the differential between idle and plotting - lets say it's X watts, then cost of plotting is :

    Cost = (x / 1000) * Number of hours to plot * cost per kilowatt/hour

    However those 100TB earn me around 12,000 Burst = 0.01428 BTC = $8.73 - giving me a profit after expenses of $8.30.

    Not exactly a loss.

    I think this is not a good example, because the average Miner does not run his Desktop 24/7. So lets assume you additional have to run a mining-machine which consumes some W of power.

    I make a little calculation with the following numbers:

    Depending on your number of HDDs you get somthing like this:

    After playing around with some numbers you get this graphs. So if you have to Power your Desktop and don´t have it run 24/7 your profit isn´t guaranteed (blue line). In this case you have to mine at least 8 HDDs with a capacity of 2TB. If you have a NUC or Single-Board for mining with little power consumption you are fine with the first HDD. (red line)

    Of course you also have to consider that larger HDDs make you more Profit. Here is another example. (In this case the Desktop is calculated with 200W power consumpiton)

    You turn your computer off? I personally never turn off my computer while it's mining. Gotta make that Burst! haha :)

    In your image, Is the Desktop power consumption of 200 in watts? Does this only reflect the average CPU usage of the the Burst Mining program? Or does it reflect the entire watt consumption of the computer?

    How did you come up with the electrical cost? Is it cost per Kilowatt? What is the rate that was used?

    I'm very interested in your post. Which is why I am asking all these questions. :)

    @piezo A desktop normally shouldn't use 200W when idle. Nice excel sheet you have there. :D

    I had also good experience with a $ 200 used HP Elitebook from 2011, which needed around 30 Watts and was able to mine 20 TB or more with all USB and Express Card slots.

    The entire watt consumption of the computer

    0,2$ per kWh (its the value for my region)

    My (older) Desktop needs 150W while mining with GPU when i activate 2 of 6 CPU-Cores. So yes, maybe 200W is to much, but not far to much. :) So here´s the image for a 150W-Desktop. I this case you make profit with the third hdd of 2TB.

    Of course you have to check how long it takes you to get your invested money for the HDDs back. Some weeks ago this was a long time. After the last pump it gets better. So let´s hope the value of BURST stays above 120 satoshi. :)

    @piezo I need to grab my Kill-a-watt from work to confirm, but I'm about 99% certain that my Burst miners are around 100W.

    My GPU miners, now that's a different story ..... ;-)



  • @jervis hilarious ! @haitch Thanks for the great work on mining power, Ill have to get the Kill-a-Watt. Did you have a reading during plotting ?! if mining will consume between 100W - 200W, plotting will be about x5 then mining (just guessing really) ? @piezo This is a heck of a study spreadsheet and will be a reference from now on, thank you for your hard work and sharing this ! As mentioned above, did you have experiment with plotting watts usage?



  • People often forget its a Game of Patience & not Calculations.... At the end, Time is Money !


  • admin

    @CoinBuster Didn't run it while plotting, but I can test it. However, based on what I saw when GPU mining other coins, it's going to be around 200-250W depending on the card.



  • With my GTX770 i get ~275W while plotting.
