Profitability Comparison
Obelisk SC1
StrongU STU-U2
Based on BTC price of $78,183 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Our scoring model gives the nod to the StrongU STU-U2, which leads on 2 of 4 weighted factors (efficiency, hashrate). Where it pulls away hardest is 1173% more hashrate (0.6 vs 7.0 TH/s). That said, the Obelisk SC1 isn't beaten everywhere — it still wins power consumption and home mining score. Cross-check the spec deltas and ROI table above against your own electricity rate before deciding.

Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Obelisk SC1 | Metric | StrongU STU-U2 |
|---|---|---|
| — | Upfront cost (MSRP) | $499 |
| -$1.18 | Daily net profit | -$3.59 |
| -$431 | Net after 1 year | -$1,809 |
| -$862 | Net after 2 years | -$3,118 |
| -$1,292 | Net after 3 years | -$4,428 |
| — | 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.
