Never dealt with Innosilicon, but I've heard from multiple sources to avoid their power supplies like the plague. Many DOA or shortly after, and they're allegedly louder than the miner itself.
I've heard the same thing - figured I would run them myself and see if I ran into any issues, and so far haven't had a single one fail. Might be that they aren't as voltage tolerant as some of the others, we run everything at 208v, so wouldn't be surprised at all if they die at 120v (if they even work at that). I normally buy any of the quality breakouts and the DPS2000BB PSU's, and just have those on hand if they fail. I've also heard that the Bitmain PSU's are pretty solid - but still not as good as the DPS's.
