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
