2300W / 220 V = 10.45 A   2 machines   

1150W / 110 V = 10.45 A  1 machine

Your thought process definitely checks out, I didn't even think about that.

In regards to panel space, it really works out to 1 breaker space per Miner, maybe more depending on what size of breakers you use, your panel capacity and how you ultimately decide to distribute your power.

I'm no expert by any means; and do not mine anywhere near the scale that you are planning on setting up. Like I said if you PM me your info, including how many Miners you are setting up and and what your location has for power currently run to the site, I can try and put you in touch with the people who made my PSU's. They sell some through ebay, but do a large part of their business directly with large Data centers. They are based in the Us out of Oregon I believe.

Hi friend,

I appreciate the help and especially the lead on Amitylabs. I actually sent them a message on Ebay and after discussing it further with him and my electrician, I've decided just to stick with the Canaan PSU's. They're giving me a pretty good price on the bulk purchase. I was kind of freaking out when I made the original post because I had a small eureka moment that I wasn't going to be able to just plug the PSU into the power outlets like people normally do in NA... and like I said above, I really know very little about how electricity actually works on this kind of scale. Been quite the learning process so far. Getting my mining operation off the ground has been a bit more stressful than I ever anticipated lol.

Mods you can close this thread, Thank you.

If you PM me your email, I can try and get you in touch with Amitylabs, they produce high quality PSU's.

Their only presence is an ebay store, and commercial customers they have dealt with previously.

I will email them and provide them with your contact info, Please also provide me with what you are needing as far as total number of PSU's. Also do you positively not want any 220V?



I can get the 220V PSUs with my order from Canaan. But my electrician is telling me that I can't set up as many miners using a 220V PSU as I can with a 110V PSU. A 220V PSU would take 2 slots on a panel as opposed to a 110V taking one slot. Granted I am a complete idiot when it comes to electricity and maybe I am misunderstanding what he is telling me.

220V PSU more V less AMPs - 2 slots on the panel
110V PSU less V more AMPs - one slot per panel

I'm no expert at electricity either, but wouldn't using 110v increase the number of amps required by each miner, in turn getting you faster to your threshold of amps in your breaker panel...for example if you run 10 machines that use 5 amps on 220v and 10 amps on 110v and your panel capacity is 100 amps.   so using 20% threshold rule you got 80 amps as a max (i might be wrong about this) then that means if you did 220v you could run 16 machines vs if you ran 110v you could run 8 machines.  I may be totally wrong but I'm sure someone will correct me if I am.

You might try looking on popular manufacturing sites like alibaba or dhgate

Looking for some help on sourcing 110v power supplies for a large amount of Avalon 741s(numbering in the hundreds). Anybody have suggestions on NA suppliers who may be able to supply these units? Would appreciate any thoughts/leads/help on finding someone for this.
