healthy, healthy but this is a bit too healthy if you know what I mean....

Why so Cryptic? Why don't you give us the info? If it involves buying through you at a markup then no thanks. Not interested.

Thank you lets pray for roi. XD

I agree, psu's are so cheap why skimp on the wattage to protect your investment, especially if you are already planning on buying a new psu for these...

when is the first wave of d3 hitting the streets? or are they already in the wild?
does it even make sense to order now for late November?
are they going to add d3 to hashnest?

i regret not hitting the proceed button on the first batch xD

September 15th in China, anyone gotten a shipping notice yet?

Works pretty well, but you have to use it to get results.

I would not skimp on a PSU. Remember, if, for example, you use 1kw, getting an equal platinum PSU over gold will save you 25$ per year @ 0.15$ kwh. A high quality and very efficient PSU pays itself in the long run. I learned this the hard way. 

You're seeing a clash between conventional wisdom and actual testing results. Conventional wisdom dictates that you should not run a power supply at 100% of the maximum rated output. This is absolutely true for consumer grade PSUs, such as the EVGA 1600w you're talking about. Server grade PSUs, on the other hand, are actually capable of outputting 100% of their rated power 24/7. When actually tested, the APW3++ was able to reach ~1600W on 110v without issue. I 100% WOULD NOT DO THAT since you'd be running way too many amps on what is likely a 15-amp cicuit. But that does imply that the APW3++ can reliably handle 1200W on a 110v circuit without issue. I've mined with hundreds of power supplies and typically see a 5-10% failure rate after 30-days with consumer grade ATX PSUs. I've only had 2 of Bitmain's PSUs out of over 300 go bad thus far (across all 4 models). I'm fairly certain that Bitmain's APW3++ is only rated at 1200W for 110v because they know that most 110v circuits are only 15amp and 1200w = 10.9 amps. Since you should never use more than 80% of a circuit's capacity, a 15amp circuit should really only be loaded with 12 amps worth of devices. Had they rated the APW3++ for 1300w, they know that people would attempt to use them for the S9, which can easily spike to 1450 watts and go above that 12amp limit.

tl;dr I think bitmain is under-advertising the APW3++'s technical limits to prevent people from overloading their home circuits - which is good.
