Thanks for covering the mod and so glad you measured power on the wall at the end there. LuxOS power estimate can be inaccurate, specially for newer models like the T21. This should still be a worthwhile modification for folks who bought Antminer T21 by accident without realizing 3 phase power requirement, or those looking to get sub 20J/T mining efficiency without spending $4000-$5000 to buy an S21.
I bought 6 not realising was 3 phase then when got it realised what the hell is this plug im in uk aswell lucky have a unit that has 3 phase set up there lol
There's so much in this vid. Don't make any decisions until you get to the end of the vid, and of course, do your own research. LOL Those power readings are crazy different. I could see you ordering a whole batch of these in the future Vosk until the power readings from the wall came in and brought reality in with a bat and bruises. haha. I wish those early numbers were correct. I was looking forward to seeing vids of you guys cranking out these like a production line to set up everywhere around your house.
Hey Vosk! Can we connect a bank of 12V, LFP batteries directly to those busbars to power the miner? Disconnect them from the PSU of course, but use the PSU for the fans and whatever that ribbon cable is. An LFP battery range is 12-14V, the PSU is 12-15V, so it should be a direct connection, but use a 300A Class T fuse in addition to the BMS. If this works, then it's really cheap to charge the batteries from solar, and you could distribute the DC to all the miners. It going to be way more efficient! If I had an old miner, I'd try it myself.
I got 8 3 phase t21 run them max power get 223th they are bullet proof comes with stupid plug I cut off wire straight into 3 phase breaker also I have free power profits are really good after halving do need to buy more 👍🏻
@@traviskelly7082 there 3 phase for a reason to distribute the load better between hashing boards may aswell get s21 if just single phase doing this mod if goes wrong say goodbye to warranty
Great for small home miners who already spent $ for there setup in single phase and want to continue filling space with current efficiency miners without having to spend more$ to have there setups re done in 3phase. I would purchase one that was pre converted and flashed, plug and play! Time is $
If you have 1000 of these you probably already have 3-phase.😁I need to find some spoofers for the new style 4-pin square fan connector. When I look at CMB, the T21 is about $1000 less than the S21. Even if you add-in the price of the PSU, it's still less CapEx ($/Th) as well as reported efficiency. I "assume" when they mine the "fee", it's to the luxor pool, can't you spoof that connection (through local DNS) and shut-down the miner (reduce power) when it's hitting their pool?
Is anyone going to talk about how bitcoin is now more profitable after the halving even though the block reward is cut in half. Wasn't it supposed to be less profitable?
Hi Vosk, probably few people know it, but the T21 if you work high voltage, you can make an OC and OV until you get about 280Th without problem, you don't need to change the power supply unless you have no choice according to your own electrical installation. T21 is much more multivalent versus S21. 👍
three-phase power supplies are more efficient, you wont get the same machine its like running a 380v stove on 220v yes you can do it, but you have less powerr and are less efficient... specially with long distance i would keep a eye on its consumption, and not just think same same but different
Incorrect, it's just a matter of the power supply design. Just because you are running it on a different design of power supply, doesn't mean you're running it at less voltage, because no matter what power supply you're running, it converts that AC voltage down to 12 volts DC.
Got a T21 today, 3p is std here, so no issue. But I cant install Braiins, anybody got it installed ? Amlogic board and 4.2024 firmware. Toolkit says installable but does let me install. Lastest version, it did the install on my S19k pro fine
update: Braiins needs an older stock firmware, or it wont run on the T21 with FW 4.2024 and later, sadly the braiins website does not tell it. The older march 2024 FW wont work either, so we have to wait some months. Or has anybody a link to the stock bitmain feb 2024 FW ? thx
@VoskCoin, thank you for all of the information. With the split, I would be at zero dollars per day. Better than negative I guess. How do I come out ahead if BTC goes to $90,000 end of next year or mid 2026? I am looking at running two of these clocked down to 3,000 watts. With the machines and the C2 I will be close to $9,000 for the set up. At 3,000 watts each I will be at roughly 80% of your output, (288 tH/s for two miners). At this rate, how do I calculate how much BTC I will be mining and then estimate that value in the next 24 months, (assuming $90,000)? Thank you for all of your wonderful info. I see this really takes a lot of genuine enthusiasm to stomach the lows you are facing with BTC right now. I greatly appreciate all of the information you are putting out there for us.
@@andya6268 You're suggesting that voltage has something to do with it, and it really doesn't. Same reason why you don't die from a hit from a 50,000 volt police taser, it's the amperage involved.
@@andya6268 Well you can go make that video with you sticking your tongue across a little 9 volt battery, then sticking your tongue across those 2 bus bars, and that will surely go viral for ya then.

Yes let’s get that T21 kit going!
the big question is how you get rid of bitcoin once you've mined it. none of our banks take it or deal with anyone who mentions crypto.
Thats incredible efficiency congrats

Nice!! They should definitely sell this as a kit.
hi, I have a question about the T21 "transformer" model.
Is it compatible for immersion cooling with the 3D printed feed cover?
THANKS
Any update on efficiency or still bad? Thank you for great videos Voskcoin, you have a great personality
How much power is required? more than 240v?

I have 3 phase power, it's 220V phase-neutral tension, so it's 380V phase-phase tension, can I run the t21 with the provided power supply?

Nice to see that halvening didnt make u go poor :D
Yes this sounds amazing please produce this conversion kit👍😁
So the stock S19/21 PSU cover panel works? Love this idea!
Can you go the other way and put the 3 phase power supply on a faster S21 pro machine?
This is a game changer... Does it have any impact on the noise level generated?
Thank you Vosk
Appreciate you!
Can u use Low Power Mode with the T21 + Luxos Firmware?

with braiins OS no spoofers are needed, but I had no luck to install braiins today on a new T21
I don't Jane enough data to watch everything but how many watts does it use?
Is anyone going to talk about how bitcoin is now more profitable after the halving even though the block reward is cut in half. Wasn't it supposed to be less profitable?
When did the halving start??????
Have dropped now..
Hey is it just me or are my miners more profitable since the having?? Vosk... This happening to you too? I'm sure it will be short lived anyway.
If a home owner puts 10 miners in a garage .. will it be profitable ??
Happy mining!
So is that 33 amps in 110? That is a lot. This would make it not interesting. Can you get that efficiency on 220?
If you're in the US, it's 120 volts.
This is 220/240v
Very interested!
Definitely interested!
I bought it and I don't know 3P what I will do 😢

Please test the power at the wall. I don't trust the firmware number
what about now after halving
three-phase power supplies are more efficient, you wont get the same machine
its like running a 380v stove on 220v
