Mine was delivered in august. high speed was 54-56th 65 watts a th
low speed was 29th it was very quiet at this speed, but it did not save a lot of power 60 watts a th
since miner is at Clifton those numbers are off the top of my head.
Topic: Whatsminer m21s arrives this sat the 27th of July (Read 816 times)
nice look forward to seeing if they changed the low power setting
The issue I got this from my reseller in China not directly from the manufacturer , it is brand new but I am not sure what batch it comes from, so it could very possibly be the exact same batch you got, either way, we will find out pretty soon, i will keep you updated.
nice look forward to seeing if they changed the low power setting.
edit: This m21s sells for 1900
Got mine a few days ago , paid 1500$ for it, it should be here , given the price of bitcoin now and the time you bough yours it seems like we paid the same amount of BTC except you got yours way ahead of me, never really had a miner from whatsminer, i have been a bitmain fan , but thought I would try something new, will post my reviews when it arrives.
I think even before the tariff situation many companies were looking for other alternatives, Vietnam for example.
I'm not so sure there's much advantage of building high cost and low complexity items like these in China vs USA. A $300 cellphone is another story ... 10X more complicated and 10X cheaper. 50% of Samsung's chip fab capacity is in Vietnam, and TSMC's is mostly in Taiwan, so the real guts of the miners are probably not originating in China anyway.

All they have to do is ASSEMBLE it outside of china

Their products would still likely be made in china.
We'll hopefully the Trump tax will motivate some American companies to get into the mining asic business. Would be great to have AMD and Nvidia in the game.
Yeah but selling gear for prices too high for 4 cent power to profit is not the way to go.
Trump tax = death for a usa miner
but even if you are in china the prices are very high. an in hand m20s 68t is more then 3000 in china.
at 9700 a coin the m20s makes 16 a day power at 4 cents is 3.20 so 12.80 profit
means 3000/12.80 = 235 days 12345Rose#
and a simple price drop puts you dead.
So the argument is pricing is now geared ar 2-4 cent with most all risk on the miner not the seller.. What big miner buys in..
We know I got a m20s at 2050 which means the builder turned profit at that price.
I see no price under 3400 for the same gear that is all profit for the builder. Risk has been shifted to the miner. Even a 4 cent guy in china has risk buying at 3400 or even 3000.
does not look good.

I don't see it going that low sadly but who knows. You and 90% of everyone else probably is saying same thing. We as well as the asic manufactures know the halving is less than a year away and most likely are expecting a big spike sometime next year before then. Gotta keep that in mind
We just need a pullback below 6K to quench the craziness and give us another chance to get reasonably priced gear. After that, a bull run to up to the halving would be great....
Down below $9700 ... could be on our way there now.

It's too bad the miner prices lately are so inflated and ridiculous it's rarely feasible or worth it. Hell I remember ordering a bunch of m20 normal ones for about $1300 each about. Now they want like $1900 for a even later shipment. Getting out of hand now lol.
It is why i hesitated to buy these in bulk. I had a chance to get more of these and of the s17 pro.
But I had not tested any. So I did not order a lot of them. If I had know they run well as they do I would have grabbed 10 and had one sub panel with 20 amp breakers and an isolation transformer.
We are going to add a transformer and do 200-250 more kwatts.
So doing sub panels with 20 Amp circuits are not a biggie.
The transformer would be in the warehouse. We have two big ones in the building already.

Yea I'm not changing breaker for one miner, plus I have 30 amp outlets which will handle it fine. Just don't want to direct plug in that. If the miner can't go on a pdu, it doesn't go for me period. I wish some pdu's had 20amp breakers, that would solve everything but sadly all mine are 15 amps each bank. I'm not always around to monitor in person so I just don't trust plugging something like this direct into a wall without a pdu or surge protectors basically. Even though I have one on my entire panel, still don't feel comfortable with it. They def. should have done a 2 plug design, would have been way better.
You can go direct to a circuit panel if you can find a proper breaker. In my case I have 30 amp breakers and only 3 of them , but if I had 20amp breaker it would be quasi okay.
What would be nice would be finding a pdu with a 20 amp breaker.
I frankly consider the 20s and the m21s units a bit of a safety risk.
To be honest the s17 pro 2 plug design is light years ahead safety wise.
I googled around and found this it may work pretty cheap price

Yea def. that's why I couldn't find anything that would work reliably. Shame too, I wouldn't mind running these units but no pdu means no buy. Stupid to plug this into wall outlet running 24/7. Imagine your dryer running 24/7 essentially, just asking for electrical problems if a storm comes through.
If you try to split it you would need to put a fuse or breaker on each leg or you're just asking for trouble. Without fuses or breakers, if one cable fails or comes loose the other cable is now taking the full load and could go up in flames.
That's the thing, I am trying to avoid using direct to wall. I have the power and the outlets available to use but I would rather plug this into a pdu somehow. I do not like plugging anything in especially 3000w+ that is running 24/7 direct to wall. It seems not many people are buying these units using 3000w+ (Probably this is why) so I can get them at a rather good price lately. Why in the living hell they wouldn't make this a 2 cord unit like the s17 is... is mind blowing. I would like to get these on my 240v pdu's somehow but no clue how. My idea was which I don't even think they make, get a like.. c13 connector to miners power supply into 2 nema normal outlets which you can plug both into a pdu. This would hypothetically split the current up between each side to about 1250w each.
Also, does this miner take c19 or c13 connection plug into the power supply?

Has anyone tried using a splitter on this miner? I feel like it's a horrible idea but figured I would ask first. I got a good deal if I want it for the 54th models of these m21s's but... I run all my miners on pdu's and even at 3240, I don't see how this can be reliable plugged into a pdu pulling that much power. Unless the power cord coming out of the unit split in 2 (Sort of like the bitmain s17's do) and I can plug them into each bank.
I use these

direct to the wall plug. so on a 30amp circuit they use 14-16 amps. I still can make it work well since I have 9 circuits to a 225 amp sub panel. And six subpanels
9 x 24 = 216 which would be hard on the sub-panel and can trip it on a 95f day.
so I do 2 of these at say 2 x 15 = 30 and 7 x 24 = 168
Thus 168 + 30 = 198 which is easier on a 225 sub panel
If we went all m20s I would truly be afraid of a meltdown since I know we run from 217 to 227 volts.

One option could be to make your own 10 AWG cable.

The datasheet for the connector says it only supports up to 12 awg wire, but I bet you could get the 10 awg in with a little effort.
