I'm pretty into the price and specs of this new miner, but I'm a bit lost about that single mains connector. It looks unfamiliar to me, and like usual with Bitmain, their site doesn't give much info besides saying it's a 25A connector. I’ve looked through tons of Google images for '25A mains connector' but can't find anything that looks like the one on this miner.
So, can anyone identify this connector?

It looks like a specialized locking 220v cord that will probably come with it.
Power Supply
Power supply AC Input voltage, Volt(1-1) 200~277
Power supply AC Input Frequency Range, Hz 50~60
Power supply AC Input current, Amp(1-2) 25(1-3)
(1-2) Max condition: temperature 40°C, altitude 0m
(1-3) One AC input wires, 25A per wire
Hopefully this helps.
Well, just by following the link you provided to the Miner S19j Pro+ product page and looking at its specifications, you can make sure that there is a standard network connector Network connection mode RJ45 Ethernet 10/100M, which can also be seen in the image of the miner, and 25A is the current consumed from the AC network.
As per my original post, I am asking about the MAINS connector, not the ethernet connector.

I expanded the shitty photo and it does not look like any power connection I know of.
It's got me stumped for sure. I emailed Bitmain and there reply was 'it uses a 25A connector'.
I would actually like to purchase some of these units but without knowing if I can obtain the right connectors, it's a major concern.
Yup. Considering Bitmain has not seen fit to tell anyone just *what kind* of connector I suspect that it is a custom one made for BM that the user has to wire to a cord themselves. If so the miner damn well had better come with it and BM needs to have them for sale at least as spares.
If it is a custom then it's terrible idea considering that there are many global-standard connectors that would fit the bill. If it *is* a standard connector then huge oversight for BM to not put the spec into their datasheet/sales ad.

not listed in parts.
I can try looking at chinese website cn and maybe part is there.
edit can not find a thing on connector.
Now I have 30 amp l6r and a lot 12 gauge and some 10 gauge. cables but I do not know of any 25 amp plugs.
Ja. Given the current most connectors are definitely into the industrial range vs anything else. thing is, next step up from 20A is 30A is connectors like these from AutomationDirect
Being industrial rated products - $$$

Your picture is nothing but fan wires and the standard antminer interface.
antminers have 2 wired connections (externally)
Network and Power
Assuming you're talking about the power cable since its the only thing looking different,
Its 100% going to just be an end that you fit yourself on a locking style c19 block end block or the whole cord. I see silver on the wire end on the power connector thats indicative of a crimp or just part of the "locking system" they are talking about. I guess someone will have one in hand soon enough to give us the scoop.

I should have killed that image.
The one on bitmain looks like it could be a c19
I have a long listing here :
https://internationalconfig.com/icc6.asp?item=57011
still can't find a 25 amp plug
home page
https://internationalconfig.com/wwpts/index.asp
this is a very large catalog. can't find the plug.
found a 20amp 250 volt
https://www.internationalconfig.com/documents/57090-M.pdf
but this miner can do 277 volts so may need a 277 volt socket/plug
here is all I got on 277 volt cables
https://www.kordking.com/277-volt-power-cords/
found a nema 7 on amazon
https://www.amazon.com/Parkworld-61582-Power-5540W-7-20P/dp/B0833XYKQZ
I think it could be a nema 7-l30p or 7-l20p
found this
https://www.signalandpower.com/products/nema-7-30p-power-cord-plug-yp-94l
rated 30 amps and 277 volts
found this
https://www.signalandpower.com/products/nema-l7-20p-power-cord-plug-yp-108?
rated 20 amps and 277 volts.

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

well if they supply a plug with 1 meter of 12 gauge 3 wire unfinished cable I can terminate it with an l6-30p and connect it to this.
https://www.ebay.com/itm/133875523116?
I have a lot of them.
I also have 10 gauge cable and these
https://www.ebay.com/itm/371651325718?
I found that Anderson Power makes a connector line that looks closer to what BM has https://www.andersonpower.com/us/en/shop/2350-1300-20-saf-d-gridr-300-single-ended-t-latch-plug-power-cord.html and looking on Amazon they are a fair bit cheaper than the IEC industrial connectors I linked to earlies but of course w/o knowing what BM uses, who knows...

yeah I saw that saf-d tag when I was looking.
well we have to wait. I am not ready to order and I may be getting 2x whatsminers next to test the liquid cooler we purchased.
I think we could do 2x m50's

Looks like you might have found a winner.
It's hard to go on these little pictures though.
Is the pin layout correct, it looks a bit different when I look at it closer?
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.
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.
https://i.ibb.co/2yG0JKf/Whats-App-Image-2023-01-20-at-9-20-50-AM.jpg
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.
