Greetings,
I live in N. Central WA so my power is cheap and I have a basement I need to heat. It's already got 2 20A 240v cicurits I had pulled for space heaters. I have two 200A panels already, so I can add more as needed.
I want to start with two S9 miners. Is there a power supply that can run two off one 240V circuit?
What are my power supply options if I want to run 4 - 8 S9's? Could I pull a larger circuit like a 50A to run 4 miners?
Thanks for any input in advance.

By and large I recommend the Bitmain APW3 PSU's, 1 per-miner. Using those the s9's will pull 6.3A each using 208v (my power strip at work (208v fed from 30A breaker) reads 19A with 3 on it) and probably around 5.8-6A each when fed 240v. 3 on a 20a circuit is quite doable BUT expect the breaker/wire/socket to get a bit warm.
2 s9's with the APW3's per 20a circuit is perfect.
Stay away from ATX supplies. Period.
