✅ Pros & Cons

✅ Pros

• Strong 100 TH/s performance with built-in PSU—straightforward deployment.

• Air-cooled; no immersion setup needed.

• Good entry-level for single-unit or small rigs.

⚠️ Cons

• High power draw (~3.4 kW) requires 220–240 V 20 A circuit.

• Near break-even or negative profit at standard electricity costs.

• Generates heat and noise (~75 dB), suiting only well-ventilated setups.

💡 Buying Tips

• Assess your electricity rate—switch to ~$0.04–$0.05/kWh to approach break-even or better.

• Consider used units; they can offer significant savings if still functional (e.g., 88 TH/s used model at $500).

• Verify electrical setup—ensure proper wiring and voltage to support the integrated PSU.

• Watch for firmware variants like M30S++ which can improve efficiency slightly (~31 J/TH).
