Of course if you think the numbers are wrong, maybe you should just point it out?
Lovely, lets also assume each GPU is watercooled as well (since you just pulled 2800MHash/s) But thats ok, i'm the owner of Koolance.
What the point when you can just assume i paid $0.07/Kwh, get whole sale price for parts and a datacenter equivalent of power grid.
I would love to see where do you live that you can pull 9Kw of power without major rewiring.
You argue you rather operate a delivering business by using 10 Civics instead of one Semi-truck.
Its amusing when you can get the civics at dealer cost as well..
Then complete omit the management cost, drivers' salaries and maintenance cost.
9000W really isn't that much, it's only around 40A. I could easily install that on my existing panel without upgrading my service, and I don't even use electricity for heating. Dealing with 9000W of heat is a much bigger challenge that providing electricity to GPU farm.
Not everyone use 240v. You might not need to upgrade your panel, but wiring isnt just your panel.
On normal 120v (single phase) it would be around 75 amps to support this. Most houses would need a major rewiring including decreasing the wire gauge to support this draw unless you used multiple 20 amp circuits on 14 gauge wire into your server room. On the other hand, if you used your dryer circuit which is usually 240 (2 phase), they are likely between 40 and 50 amp circuits and that would work as long at you used like 10 gauge wire or less into your room.
