In this post, we cover the key specs, efficiency profile, and market positioning of MicroBT's Whatsminer M60S series — the company's most efficient air-cooled SHA-256 miners on the market today.

TLDR

Whatsminer M60S Series At A Glance

• Manufacturer: MicroBT
• Series: Whatsminer M60S
• Release Date: October 2023 (M60S) — May/July 2024 (M60S+, M60S++)
• Algorithm: SHA-256 (Bitcoin)
• Cooling: Air-cooled
• Efficiency range: 15.5–18.5 J/TH across variants

Models

Background

The M60S series is part of MicroBT's Whatsminer M60 generation, launched in October 2023 and expanded through mid-2024. It represents a significant efficiency leap over the prior M50S generation (24–26 J/TH), with the base M60S landing at 18.5 J/TH and the M60S++ pushing down to 15.5 J/TH — competitive with Bitmain's S21 Pro. The series spans four air-cooled variants across two hardware revisions, giving operators flexibility to match hashrate and power draw to their specific facility constraints.

Specifications

Hashrate

The M60S series covers 170, 186, 188, and 226 TH/s across its four air-cooled variants. The 186T is the most common on the secondary market. The M60S++ at 226 TH/s is the highest-hashrate air-cooled Whatsminer available today.

Efficiency

Efficiency improves across generations within the series: the base M60S runs at 18.5 J/TH, the M60S+ tightens to 18.0 J/TH, and the M60S++ reaches 15.5 J/TH — a 16% efficiency improvement over the base model within the same product family.

Efficiency comparison against prior MicroBT generations:

Power Draw

Power draw ranges from 3,145W (M60S 170T) to 3,503W (M60S++). Despite the M60S++ delivering 226 TH/s, it draws only marginally more power than the base M60S 186T — a direct result of the chip efficiency gains in the 2024 hardware revision.

Cooling

All M60S variants are air-cooled, using MicroBT's dual high-speed fan configuration. The 2024 M60S+ and M60S++ models ship with a revised chassis (430 × 155 × 226 mm vs the original 155 × 226 × 430 mm orientation) — operators should verify rack compatibility before mixing generations within the same row.

Hashcost Breakeven Analysis

Hashcost measures the electricity cost to produce 1 PH/day of hashrate — Luxor's metric for comparing mining economics across machines and power rates. The table below shows hashcost for each M60S variant across a range of electricity prices, benchmarked against the current hashprice of $38.53/PH/day (as of May 2026).

Green = hashcost below current hashprice (profitable). Yellow = approaching breakeven. Red = hashcost above current hashprice (loss on electricity). At $38.53 hashprice: M60S/M60S+ remain profitable through $0.08/kWh with breakeven at ~$0.087–0.089/kWh. The M60S++ stays profitable all the way to $0.09/kWh with a breakeven of ~$0.104/kWh — a meaningful buffer advantage for operators in higher-cost power markets.

LuxOS Firmware & Profitability

LuxOS now supports select WhatsMiner models. Luxor recently expanded LuxOS firmware beyond Bitmain hardware to include MicroBT's WhatsMiner series — making it the first enterprise Bitcoin mining firmware to support multiple OEMs. Initial support spans select models in the M50 and M60 series, with additional model support rolling out over time through a phased approach.

WhatsMiner fleets running LuxOS gain access to Power Targeting, Advanced Thermal Management, safe rapid curtailment, and faster ramp-up time. For the full list of currently supported models, visit docs.luxor.tech.

Mining operations running WhatsMiner hardware can express interest in access at luxor.tech.

How to Buy the Whatsminer M60S

The M60S series is available on the secondary market across all four variants. Luxor's ASIC Trading Desk sources M60S inventory and can accommodate both single-unit and bulk orders.

Final Take

The Whatsminer M60S series is MicroBT's strongest air-cooled lineup to date. The base M60S at 18.5 J/TH represents a clear step up from the M50 generation, while the M60S++ at 15.5 J/TH reaches efficiency parity with the best air-cooled machines from Bitmain. For operators already running MicroBT fleets or looking to diversify away from a single manufacturer, the M60S series is the natural upgrade path.
