NFW - what about for those of us in 110/120v land? I'm ordering an Avalon 741 am trying to find the absolute best PSU for it. I saw the EVGA 1300w suggested in a post by canaan on their website, but is there something more miner-specific and better suited like the bitmain but for 110/120v w/ an A741? I know the HPs/Sidehack are a great option but there seem to be better options? having a couple dozen w/ zero problems ever must be preetty nice..
Well, without using an industrial rated 240-120v transformer (and losing about another 3% eff) the only real choice is Bitmains APW5. It works on 108-120v for de-rated max of 1,600w as I recall. Price is actually on-par with high-end ATX PSU's so in my book, worth it.
