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.
