Would anyone mind verifying my math here? I'm trying to estimate the cost of mining for a month under the following assumptions. This would exclude the cost of other onboard system components (I'm running it from my personal desktop).
-My CPU draws 84W TDP, and my GPU 150W TDP
-I run my system 24 hours/day x 30 days and try to keep things as cool as possible
-local electricity price is $0.1196/kWh
234W of drawn power x 24hrs = 5,616 watt-hours
5,616 watt-hours x 30 days = 168,480 watt-hours-days
168,480 watt-hours = 168.48 kilowatt-hours (kWh)
168.48 kWh x $0.1196/kWh = $20.15
Roughly $20 bucks added to my power bill for a month straight of Z-cash mining? Is this a realistic number or am I off by orders of magnitude? Also am I forgetting any major factors? Perhaps a minimal additional contribution from the increased power draw of my cooling fans...
