Profitability Comparison
Whatsminer M30S++
Whatsminer M50S
Based on BTC price of $78,183 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Two generations of MicroBT's Whatsminer line. The M30S++ was the refined version of the M30S era, while the M50S launched the next generation.
The M50S brings a meaningful efficiency improvement over the M30S++. As with most generational upgrades, the newer model wins on efficiency while the older model may be cheaper on the secondary market.
Spec Deltas
Here is every spec where the Whatsminer M30S++ and Whatsminer M50S actually differ, with the gap quantified:
- Whatsminer M50S 13% more hashrate (112 vs 126 TH/s)
- Whatsminer M50S 6% better power draw (3,472 vs 3,276 W)
- Whatsminer M50S 16% better efficiency (31.0 vs 26.0 J/TH)
- Whatsminer M30S++ 6% better weight (12.0 vs 12.8 kg)
- Whatsminer M30S++ 6% more heat output (11,847 vs 11,178 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 M50S |
|---|---|---|
| $2,300 | Upfront cost (MSRP) | $3,200 |
| -$4.30 | Daily net profit | -$3.33 |
| -$3,871 | Net after 1 year | -$4,415 |
| -$5,441 | Net after 2 years | -$5,630 |
| -$7,012 | Net after 3 years | -$6,845 |
| 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
Is the M50S worth the upgrade from an M30S++?
At electricity rates above $0.06/kWh, the M50S's efficiency advantage typically justifies the upgrade cost within a year. At very cheap rates, the M30S++ may remain profitable enough to keep running.
Can D-Central service both M30S++ and M50S models?
Yes. D-Central provides repair services for the complete Whatsminer lineup, including board-level diagnostics and component replacement.
