But  the funny thing is  the s17 pro 53th is still better then the s17+ 73th
So the purpose of bgger and more power does not really help much

other then a huge farm  since :

1000 s17 pros do 53 x 1000 = 53ph and use 2000 power cords with 1000 eth cables.

800 s17+  do 73 x 800 =       58.4ph and use 1600 power cords with 800 eth cables.

So  there is some savings in cables maybe some in shelf space  if you run a 2.3 mega watt farm.

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

exactly why I would rather see them cut these things in half - I love the efficiency, I just do not like seeing so much hash in one unit would rather have 2 that equal 70 then one that equals 70

Ditto.
For me (running 460-480TH) the risk is what happens when a 73TH miner goes down hard: That would be waaay too high of a percentage of my hash rate offline for at a minimum of a few weeks. Unless you are running a farm with 10's-100's of PH losing that much from a single miner failure is unacceptable.

If we ever do all upgrades in Clifton NJ we could do 350kwatts maybe 400.

At the moment we have 160kwatts  available and have around 110 in use maybe 115 K-watts

So if we add 40-50 kwatts to be maxed which is on schedule to happen. I don’t want any s17+

I ordered a s17 53th ..........  it. pulls 2300 watts
I ordered 2 t17e 106th they will pull 6000 watts
I purchased a1041 37th ....... it pulls 2500 watts

That is 10800 watts of the 40-50 we have idle.

I will be buying the s17 53th or the s17 pro 50th. Once I get the a1041 and the s17

We may want 10-20 s17 and zero s17+

I would do 1 s17+ and 1 s9  =  2950 + 1350 = 4300 watts which is no worries

I think you meant 1(bolded) instead of 2 in this calculation. Just a friendly edit Smiley


I am presuming they are using one cable to power 1.5 board? With the other one covering the other half. The tricky part would be making sure the fans run, so probably a fail-safe power from both cables 'just in case' with the normal cut off if the temperature reaches X degrees.

You can power-up two boards with from 2 PSU (found this guy who did it https://youtu.be/Af76eBsH35A?t=480/ )

Not sure about the half a board powered by one cable and the other one by another, unless one cable does 2 boards and the other cable the other board and the 4 fans and PSU fans  Huh would love to know more though.

Found this about them https://www.antminerdistribution.com/wp-content/uploads/2019/05/S17-S17-Pro-T17-Server-Manual.pdf but nothing about the power cables (or at least I did not see)

Actually, I think they integrated something similar to Nvidia's GPU's power delivery.
I noticed when powering my S17 Pro, whichever power port I plug in first, the controller and all fans turn on, but hashboards seem to wait for both ports(haven't really played with it much so I do not know if this works for extended amount of time, but I had to plug out and in a couple of times so that is what I noticed).
Therefore, I guess there is some sort of chip which tells the miner that one port is plugged and it just turns on controller and fans and as soon as second port is plugged as well, it turns on the hashboards and miner.

all my circuits have switches - I am not brave enough to power up the miners with only one cord and then plug in a second cord - seem like a chance to screw up the miner - kind of like powering up an s9 with only one hashboard powered and then plugging in the others after you turn it on.

Makes sense to have protection on the double cord powering the equipment.


Also, did some math and based on the previous prices and I would expect the following prices range for the S17+ and T17+:

Based on J/TH:

s17+   3285   W      45 j/th
73 th/s   low                 average              high   
                   $2,250.00        $2,700.00              $3,150.00   

t17+   3520   W      55 j/th
64 th/s   Low                 average              high   
                   $2,090.00         $2,365.00              $2,915.00   


Based on $/TH

s17+         
73 th/s
   low                  average             high
                   $2,832.17          $3,212.00             $3,650.00


t17+         
64 th/s
   Low                  average              high
                   $1,472.00          $1,664.00              $1,920.00


Waiting 'eagerly' for tomorrow  Undecided.

Edit: checked my V and sitting very nice between 235 - 242, with and 80% load should be ok to place 3k on one 32A breaker I think. Will have to read some more on the thickness of cables and see what I have

Has anybody had a chance to look inside the PSU to see how BM is powering them?
They damn well better actually have 2x PSU's in the 1 case as just doubling the power inlets/cords to feed a single supply violates regional electrical codes everywhere on the planet.

That said, running multiple PSU's with 1 per-hash board or some other grouping would make sense as it gives the ability to have the PSU voltage be better optimized per-board.

S17+ at $2833, $38.80/th. T17+ at $1802, $28.16/th.

That's lower than I expected based on prices of the S17 and S17 pro. S17+ is listed as "Pre-Order" with the promise of giving credit if Bitmain decides the value of the miner dropped before shipment.

The Dec. "Pre-Order" batches of the S17 53th are no longer on the website, but they were priced at $2107, or $39.75/th. So at this moment, it looks like people that ordered the S17s for Dec. delivery probably have some credit coming to them if BTC price stays in this range.

S17+ 40 w/th
S17 45 w/th
T17+ 50 w/th

That would suggest the current "Actual Transaction Price" for the S17 per th would be halfway between the S17+ and T17+ at $33.48/th, or $1774.44.

I am running 3-phase 60 amp 208v circuits in an industrial building and these will still pose a problem for me.  My 60 amp circuits can only power 17.3 kW to stay below the 80% NEC safety margin and I can only put 5 of these per circuit, which really means 3 per circuit since it has to be balanced.  So I will probably run 3 S17+ and 3 S17 per circuit to balance it and stay below the 17.3 kW max.

Running these at 208V might be borderline. They haven't given a range for the + models yet but assuming they are the same as other S17s it will be 200 - 240. Only a 5% dip in your 208V and you'll be below 200V.

Also would be getting dangerously close to the limit of the C13 power connectors.

Anyone have S17s running on 208V without issues?

I have issues we are 208 3 phase.  But it tends to read 217 to 227.

Every once in a while we drop to 187-190 this drops out a lot of the gear.

Most comes back but we often have 2 or 3 units down due to this issue.

I finally found a good regulator it does 20 amps so even when I drop to 187

20 x 187 = 3740 watts

these regulators
have kept my s17 running
Have kept my t17 running
Have kept my Innosilicon t3 t40 running.

But it don’t want to have 50 of them. I have five at the moment.

Based on the current BTC price and difficulty got this put together for current Bitmain Gear for sale with maximum delivery date presented as the first day of minig:

https://imgur.com/kDPVi26

It presumes a date for ROI which includes, where applicable, the additional days after the Halving included in the chart.

Other matters calculated:
Start to mine date based on the delivery date advertised by Bitmain.
The first column of ROI date does not include the extra days required after the halving.
For after fees BTC outcome per day the TH/Day I've used is my BTC.com pool stats payments.

Current BTC price used: $8330

Other things that each individual have to consider and/or add to the chart:
Transport fees
Customs
Electricity Cost
Difficulty Increase
Delivery delays (ie. Stock issues, Customs holdups, acts of God, etc)
Halving Considered but no speculation on Price after.

So drop in

4 cent power cost and where do the numbers go 2kwatts = 48 kwatt a day  say 50 x 4 cents = 2.00
6 cent power cost and where do the number  go    "                  ""           "   "    50 x 6 cents = 3.00

most of the units are more then 2kwatts or more then 50 kwatts a day.

Can anyone confirm how many power cables will the T17e have?

i can't seem to find it on the description page: 4. Please kindly note that power supply is a part of T17+.

Was worried not to be hit by a surprise 1 cable only due to this: '11. The pictures shown are for reference only, the final shipment version shall prevail.'.

Ordering one for December, fingers crossed for 2 plugs  Cheesy

It is no different than the s17 or t17 currently, they all have 2 plugs.  (It's a basic fuck you to whatsminer from bitmain by doing this lol).

Agreed, two plugs splitting the load is a great idea. And even though they're pricey units.... has anyone else achieved the efficiency rating they have?

In my situation, I did not consider ROI because I used stock trading gains to buy the gear for the most part. My goal is accumulate as much as I can, at the lowest power cost possible. Until i sell everything in 2027.
