they sound like good miners and all but all of them are sold out been looking at many pages and still cant find one where its out of stock the only place i see miners are in amazon and they are old and still expensive does any one have any opinion

We are very satisfied with these units. We have the mid tier M31s.
If anyone knows where to find any of these units in stock, please share.

Yes they are legit

Well, if it sounds too good to be true...
Did some more digging. Might be legit: https://bitcointalksearch.org/topic/beware-of-whatsminernet-5028653.

it is a good deal if they are real.

Considering the current price and availability of Bitmain's S19's...... this has popped up on my radar https://whatsminer.net/product/m31splus-80t-presale-april2021/
M31s+
and it available a whole lot sooner.
But I've only run Bitmain gear and have no experience with MicroBT gear. Just looking at one unit, so I can run a circuit just for that with the higher watts/amps.
Edit: but now I'm seeing different websites. Whatsminer.net vs .com. Oh, the fun of navigating scam sites

Yea, but it's also odd to be concerned on ROI with gear with a kwh rate that high.
Could be he just was fixing on an older time.
It is pretty much a 1-5 cent a kwatt game now.

A 10 cent a kwatt home miner is doing so for reasons other than profit.
Am I totally miscalculating or will these ASICs never break even? I just used whattomine for the 30S++ at 10 cents and the breakeven is at about 21 years.
Bitcoin mining is no longer profitable on 'normal' / typical home electric rates. Unless you have free power or extremely cheap power, you would never break even. If Bitcoin sees a huge bull-run (significant increase in price) this could change of course but it seems the days of profitable mining at home are over.

used to be 10 cent mining ⛏ was okay.
as you see it is not.
this gear takes longer then a year with 5 cent power.

10 cent mining is not viable at this time due to price of Bitcoin and recent halving.

Yeah both my p20 psu's rated for 3300 watts died.
they were replaced with p21s psu rated for 3600 watts.
I would just prefer to run all this gear at 3000 watts.
Rather then push like they do.

Sounds like you have a different way of specifying cable diameters. In this country we refer to cable by the cross-section of the conductors in mm. I used 2.5mm cable for my Whatsminers which is rated at 25A. In theory this is plenty to run at 3750w but I don't feel comfortable with the miners running that fast constantly.

so unlikely to cause any issues with the wiring however even with my high voltage this is slightly over the 16A rating of the connectors.
Folks - the C19/C20 connectors can be rated up to 19 amps - not 16A.That said, it all depends on the wire size used on the cord: Per the IEC ratings using 'normal' 14/16ga cords yes the limit is 16A however with 12ga cords it then goes up to 19A - that is in most countries outside of North America. In the US and possibly Canada the rating remains at 16A. In short, use a heavy gauge cord and the connectors are fine.
As to if the PSU's can handle nearly 4kw, thass another story...
I don't run at 3750 watts, that is only in 'high power' mode. I tried it to see what it does, and it appears to run them literally as fast as they can go. I was seeing 89T on some of them (7T over rated) and pushing 3750w.
I run in 'normal' mode, which seems to be fine with power ratings well within spec:
The one running at 54T has a faulty hashboard.

Mine are
m10
m20
it annoys me that they did not target 3000 watts for normal
as the margin of error would be 3000/205 = 14.7 amps easy peasy on gear.
they could give a higher setting actually four settings
2400 watts for efficient
3000 watts for low
3300 watts for normal
3600 watts for high
Be careful of your gear on long term runs at 3750 watts.
I have been mining since 2012 and you can get in a zone that seems good but in reality you are just exceeding the true safety of your parts.
If this is so you could see fails in months 3-5 as the ever so slight over watts is like fine sand paper slowly but surely wearing out a wire's coating.
A better example are marble steps that wear out over a long time decades before it shows.

The new ones all insist on running a c19 to c20 connection at very high watts. 3472 watts / 208 volts = 16.6 amps constant run on 20 amp connections that rate 16 amp constant run.
Pisses me off that they simply refuse to build them safely. 3472 watts = 5% = 3645 watts / 208 = 17.5 amps constant run on a 20 amp connection that rates 16 amp constant run.

Interesting... I have 24 x M31S+ 82T and I find that they ALL run 10% higher than their quoted power consumption. Further, in high power mode (which I don't use), some of them draw as much as 3750w. My voltage is good (around 243-244 volts) otherwise this would be a serious problem. I am using custom power leads (made from 2.5mm flex and bulgin connectors) on 20a breakers, so unlikely to cause any issues with the wiring however even with my high voltage this is slightly over the 16A rating of the connectors.

Likely the psu's will struggle again but mBT has considerably less RMA and seems to work to fix these in a reasonable amount of time for later batches.

Today 17 April 2020 MicroBT announces the fourth generation of their WhatsMiner Hardware.
M30S++:
M30S+:
M30S++:
- Hashing Power: 112 TH
- Power Consumption: 3472 W
- Efficiency: 31 J/T
- Price: 3899 $
M30S+:
- Hashing Power: 100 TH
- Power Consumption: 3400 W
- Efficiency: 34 J/T
- Price: 2740 $
How positive are you about these prices? $1000 for a difference of 3j/T and 12TH does not look reasonable to me.
lol anyone who orders this is a moron. s19 same specs.. actually ship when they say vs whatsminer last year, 2 power cords instead of 1 (able to run on a pdu that way) and less money. Literally NO benefit of these miners over a s19.
I agree prices are high in compression to S19, Bitmain almost always had the best combination of price, efficiency, and delivery over Microbt, but there is a very important factor which most of us seem to be ignoring and that is QUALITY, some people are reporting up to 25% attrition rate for the S17, and given these gears are still new and we don't have much data, the real numbers are undoubtedly worse, I have literally had over 50% of the last a great I bought from Bitmain fail, I have a room full of dead hashboards from different bitmain models, I don't even want to talk about the antmienr S9k, on the other hand, I gave Microbt a shot and went with the S21s and I got to say I love the quality of these gears.
If you search the internet you will notice that a dozen people have a truckload of issues with all different kinds of Bitmain gears, but you seldom find someone who complains about Microbt quality.

The one year warranty is awesome, but is that only for preorder?
Agree that's pretty cool that they are offering one whole year of warranty, it shows that they really believe in the hardware they built. I think as i remember correctly the warranty is not just for the preorders but for every order. (i'm not 100% positive tho)

Thanks for follow up.
I would not mind having a few.
I have a few m20s one does 68 other does 40
I have a few m21s they do 53th
I had 10 m10 now 2 one does 22 other does 28
I had 2 m3 now gone
They all tend to run hot on top speed setting.
Support was so so from pangolin.

I fear having 20 of these since a meltdown is pretty likely.
My power is pretty tight at 218 to 228 which is a bit better
3472/218 = 15.9 amps this is barely legal to do according to code in New Jersey
3645/218 = 16.7 amps this is not code.
I really would like a 3000 watt or less unit if they insist on the c19 to c20 connection.

That's one of the many screenshots that i took during the announcement livestream, i don't think it was posted in alot of places that they were doing it. Maybe that's way there isn't much info about it.
Yeah, those are both pages that I already found. But as you said, it could be insider info. I will wait for official one for now.
https://www.microbt.com/?locale=en
does not seem to list the 30s++
but I am assuming he was given insider info as I have seen this happen at times with the m10 and the m20
I did find a page with the 31s+
and better prices would be needed to sell product.

Correct me if I am wrong, but I think M30S 88T was announced in December. However, it's good to see that it is finally being released.
Also, I cannot find official announcement from them (when I do, I'll give you merit).
And on Whatsminer's website from 30 generation, I only see:
M30S
M31S
M31S+
Also, I do not like their pricing AT ALL. It's even more aggressive than Bitmain's.
