Mining Calculator MicroBT Whatsminer M30S++

We’re dissecting a true artifact, a living legend in the world of mining — the Whatsminer M30S++. Released in October 2020, this machine was one of the first to break the 100 TH/s barrier, and at the time, it seemed like an absolute marvel. Today, its 112 TH/s no longer inspire awe, but the fact that it’s still in operation and being discussed is the best testament to MicroBT’s phenomenal build quality. This isn’t just an ASIC; it’s a benchmark of reliability for its generation.

However, time is relentless, and its main enemy is physics. With a power consumption of 3472 W, we get an energy efficiency of 31 J/Th. Compared to modern machines operating in the 15-22 J/Th range, this looks like outright gluttony. This figure spells doom for any farm with medium or high electricity costs. The M30S++ burns too many watts for each terahash mined, making its economics extremely vulnerable to increasing network difficulty and falling prices.

Despite this, the M30S++ still has its army of fans. The reason is simple — it’s built like a tank. The recognizable elongated, narrow body, a simple and effective two-fan cooling system, and its reputation as an “indestructible” machine have made it a hit on the secondary market. This is a machine you know what to expect from: it will work stably for years, requiring minimal intervention. For many operators, predictability and fault tolerance are more important than chasing peak efficiency.

So, who needs this veteran today? Its niche is crystal clear. It’s an ideal choice for miners with access to conditionally free or dirt-cheap electricity — for example, from associated gas or surplus hydropower generation. It’s for those who can afford to ignore high OPEX due to minimal CAPEX (low purchase price). The Whatsminer M30S++ is not a race car; it’s a reliable tractor that can still plow, but only with very cheap fuel.
