Assuming 1kW and you pay 0.15ct for each kWh that would be about 3.60 every day on power consumption. That's a little bit more than the value of generating one block (which gives you 50 bitcoins).<br/><br/>As you're expected to generate one block each day, <b>you would actually lose money generating bitcoins</b>, even when you got that $2000 system for free. Of course this is assuming you pay a more or less standard price for electricity, don't have any excess self-generated electricity, you don't recycle waste heat, ...<br/></div><br/>Most of those power calculators will show you only the peak power needed which is generally at startup time, not at full load running. This is good for selecting the power supply you need but not so good for estimating the power costs over the long run. Unless this 6 socket beast is seriously different from smaller systems in that way.<br/></div> text/html
