Yes , this really helps , if I use it for S5+ and connect 14PCIE 6pins of them, which ones I should connect , or just choose any 14 of them . thanks

James,

the PCIe connectors are all soldered to a common 12V, so any one is fine. I have run the cables/connectors up to and over 300W each with single-cable powered Neptune modules without a problem. Contact J4bberwock directly and he can quote you for a bulk order, if you are in North America and are looking for a small quantity to sample PM me.

As I mentioned before though, I would be hesitant to run a full S5+ off a single 2880W PSU for long term as it is over 3100W DC draw. However 2x PSU's for 3x S5+ would work well IMO and still give you better efficiency from the PSU's.

I don't understand how if you worry about a single PSU and a single S5+, why THREE S5+ and TWO PSU's would be OK. Did you get things a little reversed here? Maybe you meant 3xPSU and 2xS5+?

I am really wonder why BITMAIN have no statement about this new rig yet, They are totally silent about this thing they are not accepting nor denying.

Could be that you just didn't read the thread;

The S5+ is now opening for sale in Mainland China market(as some one has already found on the bitmain.cn), and it will be available for sale on global market next Friday. Then you can purchase the S5+ on our official website of bitmaintech.com.

We are preparing the oversea sale of the S5+. Right now we are very sure on Friday we can open the sale officially, if nothing unexpected happen.

Thanks for the clarification, i didn't read this before, i haven't seen anything or any news about Antminer s5+ even on Bitmain chiness website,but it's already Friday today so let's see what result do we get.

We did not find the breakout boards for 2880 PSU on your store, does this board also transfer the AC socket onto the board or not ? Could you show me please , we may purchase some for our customers in future .

Below are pics of his board. Yes it transfers AC through the board as well.

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

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.

not sure that would be very good for my 2 MW facility. that is a shit ton of work!

I priced it out and with my 1 MW facility it would have added at least 100K USD to the overall build out cost. I'm willing to do a lot of work to get that. Most of that would be in the overpriced power supplies that are bundled with the miner making the overall cost per ghs that much more. Saves money ongoing because I can guarantee you my server power supplies are more efficient than say the ones in a S4. 1-2% savings of 1 MW let alone 2 MW will add up quick.

The key is the automatic wire cutter stripper machine: https://www.youtube.com/watch?v=3vb0RM1xMCw

I liked the screw terminals of the S1 but the plug and plug of pcie on both ends using the breakout boards allows for easier swapping of equipment. Which, when mining on an industrial level that is pretty much an ongoing task.

Also don't forget the modularity it has in that it allows us an upgrade path to new hardware without having to buy the power supplies all over again.

For medium amount of cables (lets say 1500+ cables), I agree that the automatic wire cutter and a semi automatic wire crimper are probably the way to go if you have someone or some time to operate them.

For even better efficiency, and for more than 5000 cables, I'd probably suggest to go for the fully automatic cutting/crimping machine:
https://www.youtube.com/watch?v=XUzsm2FQteA

The cost is roughly $6k for the automatic machine.
Semi automatic crimper + automatic wire cutter/stripper will cost $2k to $3k depending on options and brand.

Of course, it takes a lot of time for the assembly of the cables.
So, as I said from the beginning, it's only a good option if you have the time or someone to make the cables.
If you don't, buying the cables and server PSUs + breakout boards is the most economical option.

There are pros and cons to use server PSU , like 2800W , you buy from china , it is 6KG each, it will be expensive shipping cost .

where are my breakout boards on your PSUs ? Wink

Care to share clock speed and voltages ?

432 chips = 7.2 times of antminer s5. With only 7.7THS that means it is underclock right ? I think there s many overclock rooms, maybe for 9THS with 4500W

Thanks..

There isn't too much headroom on the S5 and S4+/S5+ (also due to heat) because of the fixed voltage.

Well with default clock and 432 chips it should be 8316 ghs right ? Or it already too hot just go by default clock ?

Since every rooms on my farm has 5500 watt caps, I wish I can get atleast near 5000 watt system. Like that S5+ OC to 4000-4500 watt and around 400 watt more for 1/2 PK AC. It doesnt matter if it goes to 0.6-.065 watt/GHS as long its under 0.7

Hi all,
As you can see the below screenshot , there are 6 x 120mm cooling fans with 4000RPM above , it is really nosie,I am thinking the possible way to make it cooled by water cooling , any ideas ?

Oh my god, this is as loud as 10 S5 if its the same fan.

I think water cooling would be challenging to say the least, i don't know if there's heatsinks that would fit and you would need to deassemble it and have the heatsinks fit just right in between the boards. There is so much heat, maybe some silent but higher cfm/pressure fan would be better.

Same noise as an S4+ at a decent ambient or a HashCoins Ares so its to be expected. It should be possible to watercool although you'll still need some fans to move air over the boards (and backsides).

I saw a gui for this s-5++ and this unit was at freq 325 which is lower then the s-5's freq 350

now can you bump this to freq 350 and push 8200gh ?

I have no idea.

The amount of heat would be crazy, that would be 3 * 24/7 Oven of heat crammed in a tiny bundle :S.
I look forward to specs but laws of physics apply to mining gear too.

Its not that bad, a little over 15,000 BTU/hr. If you wanted to air condition it a small 1.5 Ton window unit could handle it. Otherwise just dump the heat to outside.
