Maybe, maybe not. A lot of places in the world suffer from brownouts which can bring voltage plummeting down to ~90v. For anywhere in Canada/USA to be a constant 100v instead of 120v to me is ridiculous. Detroit is a special situation though, I suppose.

I'm fortunate enough to have one of the best electrical utility companies in the world (Hydro Quebec) servicing me, so I don't have to worry about low voltage situations. I draw a constant ~100-120A from my 200A home electrical installation, and still show 118v/236v at the wall. That being said, I would gladly pay an extra $20 per miner if it meant having an actual quality PSU in the unit. When it comes down to it, these high wattage power supplies almost have enough current to arc weld. I have absolutely no faith in a no-name Chinese power supply company, and my worries were proven right with the S4. I don't care if it's made in China, as long as it caries a known brand name with specs and reputation that I can look up. I'll pay extra every day if it means getting a hassle free PSU from the likes of Seasonic, Flextronics, Delta, Super Flower, etc. Apluspower Co. doesn't inspire any faith at all, and is a fire hazard in my books.

I'd like to believe that the revised power supplies from B2 will solve the issue, but there have already been reports of burnt out/DOA PSUs. I'll be replacing mine with 2000w Deltas to be safe, and when I sell them they will still have working OEM PSUs.

Its worth noting that there is nothing wrong with those B1 PSUs for computer use - the problem was caused by the unusual loading pattern miners have. This turned would would be considered sensible cost saving [/earlier development] into a failure mode.

Unusual pattern or not, if it was a quality unit it would have handled the loads. There was a lack of engineering somewhere along the line at Apluspower Co. that resulted in them failing where a proper PSU would not have failed.

This, I guess.
