Profitability Comparison
Whatsminer M30S
Whatsminer M30S++
Based on BTC price of $78,170 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Two generations within MicroBT's M30S lineup. The M30S was the base model, while the M30S++ represents the most refined version with better binned chips.
The M30S++ offers meaningfully better efficiency and hashrate over the base M30S. On the used market, the M30S++ is the better investment if priced reasonably, as its better efficiency extends its profitable life at higher electricity rates.
Spec Deltas
The Whatsminer M30S and Whatsminer M30S++ diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Whatsminer M30S++ 27% more hashrate (88.0 vs 112.0 TH/s)
- Whatsminer M30S 4% better power draw (3,344 vs 3,472 W)
- Whatsminer M30S++ 18% better efficiency (38.0 vs 31.0 J/TH)
- Whatsminer M30S 4% better weight (11.5 vs 12.0 kg)
- Whatsminer M30S++ 4% more heat output (11,410 vs 11,847 BTU/hr)
Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Whatsminer M30S | Metric | Whatsminer M30S++ |
|---|---|---|
| $1,500 | Upfront cost (MSRP) | $2,300 |
| -$4.86 | Daily net profit | -$4.30 |
| -$3,274 | Net after 1 year | -$3,871 |
| -$5,048 | Net after 2 years | -$5,442 |
| -$6,822 | Net after 3 years | -$7,013 |
| Does not pay back at current rates (negative daily profit) | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.

Frequently Asked Questions
How much better is the M30S++ compared to the base M30S?
The M30S++ typically offers 15-20% better efficiency than the base M30S. This translates to noticeably lower electricity costs and extended profitability at current difficulty levels.
Are M30S and M30S++ parts compatible?
Many parts are interchangeable within the M30S family, though hashboards from different tiers may not be directly swappable. Control boards and PSUs are generally compatible.
