....And statements that assert that substandard performance at 110 volts is not a problem because customers can always host in a datacenter instead of running their machines in a home or office environment are disingenuous. ...
At 3kW, you won't be running on a standard home/office circuit anyway. (North-American plugs are generally limited to 12-15 amps of continuous draw (1320W-1650W at 110V, power factor of 1.0)
Edit: I suppose you can hook it up in the kitchen where the outlets generally have two branches (The SP30 does have two supplies).
Adding a 240 volt circuit to most houses is trivial and cheap. If you can afford 4K for a mining device, you can afford another 50-200 dollars for a new circuit or, worst case, a new panel with a new circuit. I find this argument disengenuous. Calling out a company for missing their target is fine and dandy. From what I've seen, Spondoolies has acknowledged that they made some errors and are working to rectify it. But bitching about a circuit or two is just plain trolling. This is high school level stuff.
To those of you who don't know how to do it and/or are afraid to, an electrician is not THAT expensive. It boggles me how people are willing to spend a small fortune on these devices and then bitch because they have to spend a pittance more to make their house compatible with the CLEARLY commercial grade equipment.
