Whatsminer M60S+ review: 17 J/TH in a 13.5 kg air-cooled box, and Nigeria's power suits it best
MicroBT's M60S+ is a 13.5 kg air-cooled machine that makes a bitcoin on 17 J/TH. It clears its power at 6¢ with room today, but the S21+ and S21 Pro return more in year one for less per terahash. After the halving, cheap power is where it belongs.
MicroBT Whatsminer M60S+ (206 TH/s)
The bottom line
The M60S+ is MicroBT's air-cooled Whatsminer from the middle of its M60 line: 206 TH/s from 3,502 W in the bin we use here, 17 J/TH. At our Argentina site, at 6¢, it makes a bitcoin for about $54,800 of electricity and returns roughly 28% in its first year at today's price. At Nigeria's 3.9¢ the same coin costs about $35,600.
Bought once its price settled, in June 2026, it has mined and kept 0.0118 BTC for $617 of power: $345 of cashflow against a $3,122 landed cost, which is what the first months of a four-year machine look like. Between now and the 2028 halving it has another 0.053 BTC in it, worth about $6,650 with bitcoin back at its previous high: roughly 2.2× its hardware by the halving, with the machine still running afterwards.
What you are buying is a shelf-sized unit at $8.71 a terahash. What you are not buying is the best return: the S21+ costs $6.72 a terahash and returns about 36% in year one in the same hall, against this machine's 28%.
Scores
| Criterion | Score | Why |
|---|---|---|
| Cashflow | 6/10 | Makes a bitcoin for about $54,800 of electricity at 6¢ and returns roughly 28% in year one at today's price. It is on track for about 2.2× its hardware by the 2028 halving. The S21+ returns about 36%. |
| Longevity | 5/10 | At 17 J/TH its line is $24.48 a petahash a day at 6¢ and $15.91 at 3.9¢. Hashprice halved, $19.44, sits between the two, so after the halving it is a Nigeria machine, which is the move every machine makes once. |
| Efficiency | 4.5/10 | A fair figure for the 2024 generation and a modest one now: the S21 XP and the M70S run 13.5 J/TH in an air-cooled box, and the M60S++ in the same case runs 15.5. |
| Quality control | 5/10 | Scored as unknown rather than as good. We found no operator reports of the M60S+ in the field that we could cite, and a repair shop's guide is a troubleshooting reference, not a failure rate. |
| Serviceability | 7/10 | MicroBT lists a one-year warranty with repair services within its scope, and the M60S family's hashboards have published repair guides. It is a 13.5 kg air-cooled unit. Hosted with us in Argentina, a fault is a parts bill and a line item. |
Cashflow and efficiency count most, because they decide how many halvings a machine clears. Reliability is scored as unknown, not as good, so it holds the total down.
Buy it if
- You want MicroBT hardware in an air-cooled hall and a unit light enough, at 13.5 kg, to rack on a standard shelf.
- Your power is at or below 6¢. At 6¢ it makes a coin for about $54,800; at 3.9¢, about $35,600.
- You expect to cross to Nigeria once, when the figures say so. At 17 J/TH its line there is $15.91 a petahash a day, well under today's hashprice of $38.87.
- You are adding hashrate in small steps, one 202 to 208 TH/s unit at a time, at $1,795 for the 206 TH/s bin.
Walk away if
- You are planning past 2028 at 6¢. Its line there is $24.48 a petahash a day, and today's hashprice halved is $19.44, so those years lean on bitcoin recovering.
- You want the most return per dollar. The S21+ returns about 36% and the S21 Pro about 36% in year one, against this machine's 28%.
- Your power is between 6¢ and 7¢ and you want room above the line. At 7¢ its line is $28.56 a petahash a day, just above the $27.74 low of last June; above 8¢, where it is $32.64, choose a more efficient machine.
- You want a long public failure record. We found no operator reports of the M60S+ that we could cite, so we score that as unknown.
A shelf-sized air-cooled box, the middle step of a line
MicroBT's own shop page lists the M60S+ at 200 TH/s from 3,400 W at the wall, 17 J/TH, in a case 430 mm long, 155 mm wide and 226 mm tall that weighs 13.5 kg. It runs on 220 to 240 V through an IEC C19 cable rated for at least 16 A, with a working temperature of -5 °C to 35 °C and a one-year warranty. Our store lists bins from 202 to 208 TH/s, and the figures in this review are the 206 TH/s bin at 3,502 W, which is our store record.
It is the middle step of a line. The M60S ran at 18.5 J/TH, the M60S+ at 17, and the M60S++ at 15.5: the same case and the same idea, with more hashrate for each watt. Two years with the M60S shows what the first step of that line has done.
What a coin costs it
At 6¢ in Argentina it makes a bitcoin for about $54,800 of electricity today, against a bitcoin price of $81,601. At Nigeria's 3.9¢ the same machine makes one for about $35,600. The S21 XP makes one in Argentina for about $43,500, the M70S for about $43,500, the S21 Pro for about $48,400 and the S21+ for about $53,200.
In its first year the M60S+ returns about 28%. The S21+ returns 36%, the S21 Pro 36%, the S21 XP 34% and the M60S++ 32%. The M60S+ is at the bottom of that group, which is where 17 J/TH puts a machine once the cheaper S21s are in the room.
Over its run since June 2026, electricity has averaged about $52,300 a coin. That is a short lifetime average; the figure to plan on is today's.
A low price per terahash, but not the lowest
The first price we hold for the 206 TH/s unit, on 24 April 2026, was $9.15 a terahash. It is $1,795 today, $8.71 a terahash, for the same 206 TH/s at the same 17 J/TH. In between it has stayed between roughly $8.61 and $9.26 a terahash, which is what a settled price looks like.
Against the other air-cooled machines we stock, it is cheap for a MicroBT and middling overall. The S21 XP, at 13.5 J/TH, is $11.55 a terahash and the M70S $12.60. The M60S++, at 15.5 J/TH, is $9.45. The S21 Pro, at 15 J/TH, is $8.61, about what this machine costs for two joules less per terahash, and the S21+, at 16.5 J/TH, is $6.72. A machine's price per terahash settles to where its efficiency, its maker and its age put it, and the guide to what a miner costs all-in shows what sits on top of the box.
Where the halving puts it
A machine's line is the hashprice at which it stops covering its own power. At 17 J/TH a petahash uses 408 kWh a day: $24.48 at 6¢, and $15.91 at Nigeria's 3.9¢. Network hashprice was $38.87 a petahash a day on 17 October on our hashprice chart, so the M60S+ clears the 6¢ line with room. It also cleared it at the year's low of $27.74 on 6 June.
The 2028 halving halves the coins a petahash earns. At today's price and difficulty that puts hashprice near $19.44, under the 6¢ line and above the Nigerian one. That is today's conditions held flat, not a forecast: it is why every projection we publish assumes the old high returns, and the forward figures here do the same.
A 13.5 J/TH machine has a line of $19.44 at 6¢, which is exactly that halved level, and that is the case for the S21 XP or the M70S if you plan to stay in Argentina. The M60S+ is a different bet: an Argentina machine now and a Nigeria machine after the halving, with the move made once. The guide to crossing once explains why, and the guide to efficiency and halvings shows where the line sits at every J/TH.
What a fault costs you here
We looked for operator threads and repair write-ups on the M60S+ and found nothing specific to it that we could stand behind. What exists is a repair shop's guide: D-Central says the M60S, M60S+ and M60S++ share the same hashboard architecture, and lists a loose ribbon cable, a loose high-current copper-bar connection and a sagging power-supply rail among the causes of a board dropping out. It also says a hot intake, above about 30 °C, can drop a chain on boot, which fits MicroBT's own 35 °C ceiling: an air-cooled machine wants a cool hall. We treat that as a troubleshooting reference and not as a failure rate, so the M60S+ is scored as unknown on quality control.
What a fault costs is the part that matters. MicroBT's shop page lists a one-year warranty with repair services within its scope. Hosted with us in Argentina, a repair is billed at the cost of the parts and nothing else, and it is a line item, not a catastrophe.
We found no operator reports of the M60S+ we could cite. We score that as unknown, not as good.
Our two cents
The M60S+ is a sound machine at a settled price. It clears its power at 6¢ today with room, it fits a standard shelf, and the one move it will make, to Nigeria, is where its figures improve most: a coin there costs about $35,600 to make.
If the aim is the most return on the money, the S21+ and S21 Pro show higher first-year returns today, at $6.72 and $8.61 a terahash. If the aim is the cheapest coin, the S21 XP makes one for about $43,500 at the same site. The figure below ranks what beats this machine on cost per coin and then on first-year return, in stock today. A coin that costs less to make is a coin you keep more of.
