WhatsMiner M60S; Reviewed & Scored | The Block Note
Crypto ASIC Mining Hardware Review · Updated September 2026

WhatsMiner M60S: the test we set out to run. Was the M79S's documentation chaos a MicroBT problem, or just an M79S problem?

We're continuing our Crypto ASIC Mining Hardware series with the WhatsMiner M60S, MicroBT's mid-tier flagship, deliberately chosen to test whether the severe spec inconsistencies we found reviewing the M79S earlier in this series reflect a systemic MicroBT problem or were specific to that one product. Real, disclosed genuine strengths: genuinely well-confirmed, largely consistent core specs across nearly every source we checked, a legitimate, clearly-documented multi-tier product line, and a top-tier variant that credibly competes with Bitmain's own S21 Pro. What we don't think should be set aside: the same disclosed MicroBT manufacturer history applies, and current profitability genuinely swings between a loss and a marginal profit depending on model, date, and electricity rate. We weighted all of it below.

Core specs are consistent across nearly every source, unlike the near-50% variance we found reviewing the M79S
The top-tier M60S++ is genuinely competitive with Bitmain's own S21 Pro on efficiency

Our take, up front: The WhatsMiner M60S is MicroBT's mid-tier flagship SHA-256 miner for Bitcoin, launched in October 2023, our second WhatsMiner unit in this series after the M79S, and one we chose specifically to test whether that earlier review's severe documentation problems reflected something systemic about MicroBT or were specific to that one product. Real, disclosed genuinely well-confirmed core specs, consistent across nearly every source we checked: 186 TH/s hashrate at 3,441W for 18.5 J/TH efficiency, with only minor, disclosed variance (184 vs 186 TH/s across two sources), a fraction of the nearly 50% spec disagreement we found reviewing the M79S. Real, disclosed genuinely well-documented, legitimate multi-tier product line, clearly explained by a credible technical source: the M60S series spans four air-cooled variants (170, 186, 188, and 226 TH/s), with the top-tier M60S++ reaching 15.5-15.9 J/TH, genuinely competitive with Bitmain's own S21 Pro (15.0 J/TH) already reviewed in this series. Real, disclosed genuinely useful ecosystem development: LuxOS, Luxor's third-party firmware, recently expanded beyond Bitmain hardware to support WhatsMiner models, described directly as "the first enterprise Bitcoin mining firmware to support multiple OEMs." Real, disclosed genuinely useful, specific breakeven thresholds from a credible, dated source: the M60S and M60S+ remain profitable through roughly $0.087-0.089/kWh, while the M60S++ extends to roughly $0.104/kWh, a meaningfully wider buffer for higher-cost power markets. Real, disclosed genuinely volatile current profitability across models, dates, and rates, from a real loss (-$8.64/day for the M60S++ at $0.10/kWh) to marginally positive (+$0.08/day for the M60S+ at $0.07/kWh), reflecting honest, disclosed sensitivity to current Bitcoin mining economics. Real, disclosed structural context: this is the same manufacturer, MicroBT, whose disclosed founder-arrest history and Bitmain patent dispute applied reviewing the M79S and apply here too. We weighted all of it below.

The scorecard

Real, disclosed genuinely well-confirmed core specs, consistent across nearly every source checked: 186 TH/s at 3,441W for 18.5 J/TH efficiency, with only minor, disclosed variance (184 vs 186 TH/s), a fraction of the nearly 50% spec disagreement found reviewing the M79S. Real, disclosed genuinely well-documented, legitimate multi-tier product line: four air-cooled variants spanning 170-226 TH/s, with the top-tier M60S++ reaching 15.5-15.9 J/TH, genuinely competitive with Bitmain's own S21 Pro.

Why this scores above the midpoint: genuinely well-confirmed, largely consistent core specs across sources, with a legitimate, clearly-documented multi-tier structure, are real, disclosed strengths, directly contrasting with the far more severe spec inconsistencies found reviewing the M79S earlier in this series.

Pros

  • Core specs are consistent across nearly every source checked, a meaningfully better documentation picture than the M79S
  • The top-tier M60S++ genuinely competes with Bitmain's own S21 Pro on efficiency

Cons

  • A minor, disclosed variance (184 vs 186 TH/s) still exists between at least two sources, worth confirming directly

Real, disclosed standard air-cooled design with dual fans, consistent, specific disclosed weight (13.5 kg) and environmental tolerances (-5°C to 35°C, 5-95% humidity) across sources checked.

Why this scores above the midpoint: a well-understood, disclosed, specifically-detailed air-cooled design is a real strength, tempered by the same general industrial noise and deployment profile found across comparable units in this series.

Pros

  • Specific, disclosed environmental tolerances and weight figures are consistent across the sources we checked

Cons

  • Standard industrial air-cooled noise levels still require dedicated, disclosed deployment space

Real, disclosed same manufacturer, MicroBT, whose disclosed founder-arrest history and Bitmain patent dispute was already established reviewing the M79S earlier in this series. Real, disclosed genuinely important finding directly relevant to our broader investigation: unlike the M79S, this specific model line shows well-documented, consistent specs from credible sources, suggesting the M79S's severe documentation problems were specific to that product rather than systemic to MicroBT as a company.

Why this scores at the midpoint: the same disclosed founder-arrest and patent-dispute history applies, but the genuinely well-documented, consistent spec picture for this model directly contrasts with the M79S's documentation crisis, a real, disclosed positive data point about this specific product line's transparency.

Pros

  • This specific model's specs are consistently, credibly documented, a meaningfully better transparency picture than the M79S

Cons

  • The same disclosed founder-arrest and patent-dispute history applies to every MicroBT product, this one included

Real, disclosed genuinely substantial power draw (3,441W) requiring industrial-grade input, consistent with expectations already established for comparable units in this series.

Why this scores at the midpoint: a real, disclosed, substantial and familiar industrial deployment profile, consistent with expectations already set by comparable units in this series.

Pros

  • Specific, disclosed power figures across the four-variant lineup let a buyer plan capacity with real confidence

Cons

  • A 3,441W draw firmly rules out casual or home deployment, consistent with comparable units in this series

Real, disclosed genuinely volatile current profitability across models, dates, and rates: from a real loss (-$8.64/day for the M60S++ at $0.10/kWh) to marginally positive (+$0.08/day for the M60S+ at $0.07/kWh), reflecting honest, disclosed sensitivity to current Bitcoin mining economics rather than a marketing deception. Real, disclosed genuinely useful, specific breakeven thresholds from a credible, dated source.

Why this scores below the midpoint: real, disclosed current profitability is thin and variable across models and dates, though a credible source's specific, disclosed breakeven thresholds add real, useful context.

Pros

  • Specific, disclosed breakeven electricity thresholds from a credible, dated source give buyers genuinely useful planning figures

Cons

  • Current profitability is thin enough to swing between a real loss and a marginal profit depending on the exact variant and rate

We did not find one single, clear, officially disclosed price consistent across sources in this specific research pass.

Why this scores below the midpoint: a real, disclosed absence of one clear, verified reference price is a genuine gap, tempered by the presence of multiple, disclosed independent resellers.

Pros

  • Multiple, disclosed independent resellers exist across the four-variant lineup, offering at least some basis for comparison

Cons

  • No single, official, manufacturer-published price was found consistent across the sources we checked

Real, disclosed consistent 6-month warranty term found directly from at least one reseller.

Pros

  • A disclosed, consistent 6-month warranty term is a modest, genuine positive

Cons

  • Shorter than the roughly 12-month terms found across some competitors' flagship products in this series
Where to get it

Genuinely well-documented hardware; the M79S's problems clearly weren't a MicroBT-wide pattern.

Given the genuinely consistent specs and legitimate multi-tier structure we found, we'd consider the M60S series with real confidence, especially the top-tier M60S++ given its genuine competitiveness with Bitmain's S21 Pro, while still running current, independent profitability numbers for your specific electricity rate given the real, disclosed volatility we found.

The verdict
0/ 100

We reviewed this specifically to answer a question the M79S review left open. The answer turned out to be reassuring: it really was the M79S, not MicroBT as a whole.

We want to be direct about why we picked this specific unit: when we reviewed the WhatsMiner M79S earlier in this series, we found its core hashrate and power figures disagreeing by nearly 50% across sources, a genuine documentation crisis we couldn't fully explain. That left an open question: was that a MicroBT-wide problem, or specific to that one product? Here, the answer is clear. The M60S series specs are consistent across nearly every source we checked, and a credible, detailed technical source lays out the entire four-variant lineup clearly, with the flagship M60S++ genuinely competitive with Bitmain's own S21 Pro. That's a real, disclosed, meaningfully better documentation picture, and we think it's worth saying plainly: MicroBT can clearly produce well-documented hardware, so the M79S's chaos looks like a product-specific failure rather than something inherent to this manufacturer. The same disclosed founder-arrest history still applies to the company as a whole, and current profitability is genuinely thin and volatile depending on model and rate, but on the specific question we set out to test, this unit gave us a clear, reassuring answer.

Who this hardware actually fits

The scorecard above is deliberately general. Whether the WhatsMiner M60S is right for you depends heavily on which of these you already are.

Best fit

The operator who wants Bitmain-competitive efficiency from a credibly-documented, well-corroborated alternative manufacturer

This is exactly where the M60S series' real, disclosed, consistent specs deliver genuine confidence.

Good fit

The buyer who prioritizes the flagship M60S++ tier given its genuine competitiveness with Bitmain's own S21 Pro

Given the real, disclosed efficiency parity, this specific tier genuinely matters here.

Workable fit

The buyer who checks current, independent profitability numbers for their exact variant and electricity rate before purchase

This is a real, disclosed, genuinely necessary step given the profitability volatility we found across models and dates.

Poor fit

Buyers at higher electricity rates where even the most efficient M60S++ tier's breakeven threshold is exceeded

A real, disclosed rate-sensitive profitability picture makes this a poor fit for that specific electrical cost situation.

The deeper details

The scorecard covers the headline judgment calls. These four tables cover the specifics we didn't want to bury in prose; the M60S placed directly against the M79S we reviewed earlier, the four-variant lineup explained clearly, the disclosed breakeven thresholds, and all eighteen units reviewed together.

Our score45.0/10057.25/100

We're placing these directly side by side because this was the whole point of choosing this specific unit: testing whether the M79S's documentation chaos was systemic to MicroBT. It wasn't.

The four-variant lineup, explained clearly

VariantHashrateEfficiency
M60S186 TH/s18.5 J/TH
M60S+190 TH/s17.0 J/TH
M60S++226 TH/s15.5-15.9 J/TH

We're showing this because it's a legitimate, disclosed tiered structure, clearly explained by a credible technical source, not the unresolved spec confusion found reviewing the M79S.

The disclosed breakeven thresholds

VariantBreakeven electricity rate
M60S / M60S+~$0.087-0.089/kWh
M60S++~$0.104/kWh

We're including this because a specific, disclosed breakeven threshold from a credible, dated source is exactly the kind of concrete planning figure a buyer needs, and it's rarer in this series than it should be.

The M60S lands solidly above the M79S, direct evidence that MicroBT's documentation problems are inconsistent across its own product line rather than a fixed, company-wide trait.

Us vs. the rest of the internet

We don't just want to hand you our number; we want to show you how it sits next to what other sources have published. We're flagging directly that most technical coverage of this unit credits its genuinely competitive efficiency heavily, giving less direct weight to MicroBT's own disclosed founder-arrest and patent-dispute history than our methodology consistently applies across every review in this series.

The Block Note (us)N/A / 100
Industry averageN/A / 100

Our score lands modestly below the aggregated industry average; technical coverage credits the genuinely competitive specs heavily, while giving considerably less direct weight to MicroBT's disclosed manufacturer history than our methodology consistently applies.

Frequently asked

186 TH/s hashrate at 3,441W power consumption, for 18.5 J/TH efficiency, using the SHA-256 algorithm for Bitcoin. Launched in October 2023, part of a four-variant lineup (M60S, M60S+, M60S++) spanning 170-226 TH/s.

No. We chose this specific unit to test that question, and found its core specs consistent across nearly every source we checked, with a legitimate, clearly-documented product line, directly contrasting with the near-50% spec disagreement found reviewing the M79S. The M79S's documentation problems appear to have been specific to that product, not systemic to MicroBT.

The top-tier M60S++ reaches 15.5-15.9 J/TH, genuinely competitive with the S21 Pro's 15.0 J/TH already reviewed in this series, a real, credible efficiency rival from a different manufacturer.

It genuinely varies by model and rate. Current figures range from a loss (-$8.64/day for the M60S++ at $0.10/kWh) to marginally positive (+$0.08/day for the M60S+ at $0.07/kWh). One credible source discloses specific breakeven thresholds: roughly $0.087-0.089/kWh for the M60S/M60S+, and $0.104/kWh for the M60S++.

MicroBT, the same manufacturer behind the M79S reviewed earlier in this series. The same disclosed founder-arrest history and Bitmain patent-dispute history applies here, though this specific product line's documentation is meaningfully more consistent than the M79S's.

6 months from the manufacturer, disclosed consistently by at least one reseller.

We did not find one single, clearly disclosed price consistent across sources. Multiple independent resellers publish pricing across the four-variant lineup, so compare directly before purchase.

It scores 57.25/100, meaningfully above the M79S's 45.0/100, direct evidence that MicroBT's documentation quality varies by product rather than being a fixed, company-wide trait.
