Antminer S19JPro 122T

[danieleither]

I got sent this image by a third party. Not sure if it is final spec or not so don't place too much weight on it. I can confirm though that the power cable will be supplied with the miner in box.

WELL DONE! This looks like the correct connector, thank you

Can I ask, what was your source (you said you can confirm the power cable will be included)?

[Corn Harvest]

It was sent to me by a broker who said it was provided to them by Bitmain. From what I can see, it’s not suitable for home mining with the supplied cable, unless you have a PDU at home.

Even more to the point - the cable is NOT listed by any organization. The connectors and wire by themselves are but NOT them being used together.

And for good reason: That C19 connector is only rated for a MAX of 20A, Bitmain specs the miner as 25A max and even the more normal 20A it would pull using a 277v line is pushing that C19 very hard.... Idiots.

I heard they will start selling PDUs for these models, probably why they have chosen a non-standard cable for this.

As for the picture above which is floating all over the place on telegram, I think there is something wrong with it, at least the connector name, I think they are confusing it wit the SP13 which is used on the Hydro versions, those are round connectors with visible pins like nails, they come in 4 pins and 7 pins, those are certainly the ones they use on the Hydro version.


Anyway, the miner won't need those 25 amps rated on the PSU, should be fine to run it with their cables, unless you are worried about insurance and stuff like that then you will have some issues explaining to them why were you using such a cable.

[philipma1957]

If that one from Anderson is it that would make perfect sense. With the miner pulling up to 25A even Bitmain would not spec the connector to be just 25A. One rated for 30A gives a perfect reserve safety margin and that Anderson plug/socket are a much smaller size than industrial IEC ones.

The miner doesn't pull 25A though.

The quoted power consumption is 27.5W per TH.

122 TH x 27.5 = 3355W

Even if we round that up to 3600W, at 200V (the lowest operating voltage) that's still only 18A.

It's not ideal to run 18A through a 20A connector 24/7, however it would be ok with around 11% tolerance.

It will pull more than 27.5 watts per th. add the four fans and the controller.

easy peasy 100 more watts. which is about 1 amp plus 18 amps = very close to 19 amps..

so they say it is 25 amp rated.  but only on the miner end. not the c19 end.

there is a fix.  https://www.cables.com/nema-l6-30p-to-l6-30r-extension-cords.html this is a 30 amp cable.

cut the c19 off bitmains cable and add this.

this is more okay if you run near 208 volts




all our wall outlets are l6-30r


so

1)30 amp breaker
2) l6-30r wall outlet
3) l6-30p to l6-30r ten gauge cable
4) mod bitmains piece of shit cable  with l6-30p to bitmains locking part

I have 1,2,3 in hand and I have l6-30p plugs

if i buy these I only need cut a non ul cable and add a better plug.

if may at least be mechanically sound.

bitmains cable is not mechanically sound at 200 volts and is not good at 205 -208 volts.

3700/200=  18.5-19 amps which will not do well in summer with a c19 plug

if bitmain cable is 12 gauge but short it may be okay.


@ mikeywith looks like whatsminers may be the move for me.

[WhyFhy]

I think its because its probably an in house solution and a step up towards 3 phase.

I imagine they couldn't find anything rated right for $20 or less so they just made one. (probably saved a lot of $ doing it too)

Bitcoin Miner S19 XP Hydro took the waterproof connectors NotFuzzyWarm shared.

these look like a step below that but a bit above a c19 as a c19's max is rated 250V and 20 Amps

So p14 is the name dubbed to this thing then huh?
18 on a 20a is cutting it close. 
Hopefully it's quality and not corner cut on awg.

It's not ideal to run 18A through a 20A connector 24/7, however it would be ok with around 11% tolerance.

Yes, that's cutting it close, but it would probably be around 1 to 2 A lower in a sustained pull, I reckon 3.6 kW would be the worst-case scenario.

Yeah if you are a mine with 208 volts and run in the summer on a high load you will be much closer to 19 amps maybe 20

I have found running in the summer gear tends to run over spec on energy use and power supply voltage tends to drop.

My guess is this is very iffy buy for a lot of mines.

2.7 x 12 x 4 = 129.6 watts at 100%

controller
https://shop.bitmain.com/product/detail?pid=18450220523100456999r2N2wUQ0066C  at least 10 watts with no fans so

129.6 + 10 ish = 140 watts that is 140/208 = 0.67 amps

28 x 122 =  3416 watts 3416/208 = 16.42 amps so 17.09 amps at best 24/7/365  if you are a 208 volt mine

I smell burning rubber here. I can assure you that a hot mine with 30 or 40 or a few 100 of these is not what I would want

Now if then had supplied a 1 meter 10 gauge cable with a l6-30p and the p14 to go to the miner you would be fine.

Instead the c19 is wrongly specced and I would bet the cable will be 12 gauge not 10 gauge

@ mikeywith looks like whatsminers may be the move for me.

I literally allowed 245w for fans and controller. 3355W for hashing, 245W for fans and controller, 3600W total. My calculation of 18A is based on 3600W at 200V, and therefore 18A is a worst case scenario.

you are too optimistic

122 x 27.5 = 3335 This is what you pick

122 x 28.0 = 3416

122 x 29.0 = 3538

122 x 30.0 = 3660

I can tell you if the mine is warm all of the numbers above need to be figured in.

AND 3660+200= 3860/200= 19.3 amps.

thats not acceptable 365/24/7

btw pulling 18.0 amps on a 20 amp socket like a c19 is pressing very hard.

I will likle be going the route of whatsminer 30s++ over these.

mikeywith may be able to help me find some gear.

If we get two m30s++ and one octominer tank 12 cooler i will do a thread on them.

if you get any of these antminers i would love to see on in action maybe with some heat gun numbers reading the c19/c20 connections.

maybe they will be cooler than i think 🤔 you could be right. I have made multiple erros in my life so my over abundance of caution may be too much caution.

I think it's fair to say the farm cooling setup will play a big part. I have 24 x Whatsminer M31S+ 82T in one of my small farms, they consume around 3700W each on C19/C20 connectors. The connectors don't even get remotely warm, however it's a cold room / hot room setup with forced air running over the miners. This factor will certainly be helping to prevent the connectors warming up.

I am thinking to do a direct replacement of my Whatsminers (now nearly 3 years old) with these 122T Bitmain units. Bitmain has since confirmed that the S19Pro+ 122T will come with a power cable / adapter with C20 plug on one end, so theoretically I should be able to plug and play with my current power leads.

If I get some I'll post some pics and info

It's better to create a leeway in these edge-case scenarios, I agree. Had a wiring meltdown once, thankfully I was in the same room when it happened.
