I had a 50 Amp sub panel installed and added a 20A 110v circuit and a 30A 220v. I'd intend to keep the machines running as long as the cost isn't more than I can afford -- I look at it as part of the investment. I imagine what the guys who stopped mining with GPUs cause they couldn't do more than a coin a day would do to go back in time and keep those things running.
EXACTLY! I'm playing roulette with my circuits here, and while I think I've gotten things figured out...for now, I'm having to turn off my Avalon which pulls like 700W for a mere 60 Gh when my defective 1 blade antminer is still pulling 90+ GH off of 240 ish Watts.
I still have an extra 1500 watts of electricity required for my soon to be built 1st scrypt rig. Looking at homebuying options because its 36 degrees outside and 89 degrees inside.
