I don't know, this thing kind of scares me. At this point I'd rather wait for the S7 which should hit soon enough.
with this out the s-7 will be delayed into October at best.

Really not so different from the S3++ that got released in China, and the S5 was not that far behind it. The S7 will be released as soon as it needs to be, so it likely has more to do with the competition's products than another one of their own. Anywhere from 1-3 months if I had to guess, depending on outside pressure.
I'd be willing to bet tapeout is either already finished or in progress as we speak for the new BM chip.

Wow, very efficient miner indeed Can you prove your website is legitimate, your account is new. Read the thread in its entirity ... the man has been made to jump through a thousand hoops already! But 28 6pin PCI-E connectors for a single rig is mind boggling to say the least. Is the 6 pin PCI-E connector the highest rated power plug that exists? 8 pin is rated at 150W officially, but for our use won't double whatever number each of us is comfortable with on 6 pin as it only adds 2 more ground wires. not to mention no home outlet will support 3400 watts.. so it would have to be specially wired in its own sub panel. and this thing looks like a fire hazard..
No? You can power it from up to 9 PSUs if you want and split what circuits the PSUs are on as you like. so i just run extension cords to different outlets? lol If they were on different circuits, pretty much. I've got 2x 32A and 2x 20A circuits (all 240v) extension-ed into one room so I can test some pretty large things if required. Did you mean the 3 modules ? yes , you can just connect each module and get around 2.5T hashrate , we may use incorrect PSU that make one board have xx , it gave us 7.1T at peak . see following screen shot . Peak means nothing, it is average that customers are concerned about and that screenshot doesn't give me any warm fuzzies about this product! And 6 fans at 4000rpm, how loud is this thing?

only 2c kwh iceland or china farms would be interested in this (or not) imho It MIGHT ROI on 5 cent electric. There are places in the US you can get under 5c/KWH though not many. for those who know ...would you be better off (or have to) use like 16awg Y cables like with the KNC Titans and Neptunes
Way overkill, even running 2 connectors per hash board would be less than 200w / connector, most PCI-E cabling on power supplies is speced to handle at least 225. not to mention no home outlet will support 3400 watts.. so it would have to be specially wired in its own sub panel. and this thing looks like a fire hazard..
I'm sure you can use seperate outlets per power supply, 3x 1200W+ power supplies should handle this unit pretty easy. Just don't power one board from different power supplies, just like on any Antminer that needs that much power per board. It would appear the actual need is for *19* PCI-E, 2 per hash board and one on the controller (fan power). Not sure why they put the 3'd power connector on each board, not that it HURTS anything. I'd be willing to bet tapeout is either already finished or in progress as we speak for the new BM chip.
I'm certain that the S7 already exists, and that BitMain is bulding them as fast as they can to replace their "farm"/Hashnet S5s they're selling off used - when they run low or out of S5s then they'll start selling the S7. I'm HOPING for end of August to mid-September but it's very up-in-the-air right now. I don't see this "S5+" unit having a noticeable delaying effect on the S7, it's just not efficient enough. Bitmain SHOULD have come out with it 6+ months ago and called it the S6 - THEN it would have had a good sized market. As of today, it's too little too late and too expen$ive.

Bitmain,
The simple truth is that you need to realise what your customers want. We want something the same size and shape as an S5 but more powerful, more efficient, and at a price advantage compared to a S5, kind of like going from S3 to S5.
Ideally, you would be able to take the new hash cards for this new machine and replace the failed cards in S5's as needed.
As for myself, I am not interested in the monster that is pictured above.
If you can't or won't give customers what we want, somebody else eventually will.
At the very least, break that thing up into middle and side units that can be bought separately.
Any chance that the hash boards for these things might work in an S5?
As we Engineers say...... Go Back to the Drawing Board!

I suspect this exactly what the Big customers have asked for. A very large Hash in a very small space. Yes the efficiency could be improved but at the expense of the Hash, and if you have very low priced electricity why would you want that...

What people are also forgetting is this is exactly what the big Chinese customers have asked for. The S5+ was not even intended for international markets.

Not to stir the pot, but how is it that PCIe connectors are only rated at 150W? That must be application-specific derived from GPU's. The connectors are based off the #5556 Molex Mini-Fit Jr connectors, which are rated for 7 or 8a (depending on type of pins used) per 12V+ circuit when used with 16 or 18awg wire (84-96W x 3 = 252-288W RATING): http://www.molex.com/pdm_docs/ps/PS-5556-001.pdfAlso in regards to temperature and current testing: ** Ratings shown represent MAXIMUM current carrying capacity of a fully loaded connector with all circuits powered. Ratings are based on a 30°C maximum temperature rise limit over ambient (room temperature).

I have purchased EVERY BITMAIN MINER since s3, s4, s5, s4+ - this one even with .05 power and NO diff increase (we know that's not going to happen) It would take over 6 months to break even!
I live in Vegas and that's a terrible gamble.
Rant over...

They didnt did this for fun! Some big customer ask for it. Unfortunatly we are small here in US. (Canada) I guess we will have to wait for S7 cause there is no other company that will deliver before. I know lketc is looking to release on august 20 but until I see the miner we cant be sure. Home mining is getting harder and harder!

You could run this whole thing from a single 240v socket....its 14amps at the voltage, would run comfortably even on the 20A circuit And you could easily run a single PCI to each hashboard, if you have a server style PSU with breakout boards...its all about running the proper gauge wiring.

you can run this in one 2880 watt psu from finksy/j4woocky
just under clock it a bit. maybe down to freq 275 or freq 262.5
you would do around 2600 watts off the 240 volt circuit and hash at 5775 gh.
or you can have 3 different 120 volt plugs like I do in my garage .
I have 5 circuits at 120 volts .
and I have 2 at 240 volts.
my question is how do I get it to be quiet .
I have to under clock it. to get it to be not be crazy loud.
I can power it safely.
I can do 10kwatts in my house safely.
The problems are sound and heat.

This is one goofy contraption. why the obsession with PCI connectors? Is that really the best solution for industrial scale mining?

If it is true that lktec is releasing their new rig on or about August 20th, then you can bet top dollar the S:Next-One from bitmain will be on the scene sooner than you can bat an eyelid! Keep your eyes peeled.

I prefer it greatly over a proprietary power supply. High end efficient used +12V server power supplies will beat new every time, not only in price but performance as well. Buy yourself an automatic wire cutter/stripper machine, some 5000ft spools of 16awg primary wire, reels of crimping pins and bags of end connectors. And you will never have to buy a PCI-E cable again, and you can make them just the length you need.

Nope, 6 pin PCI-E connectors have certainly run their usefulness, both economically and practically. They should have reverted to the trusty old screw terminals that were sported on the S1.
