Antminer S21 Pro+ vs S23 XP Hyd: which to quote
Direct answer: Quote the Antminer S21 Pro+ when you want efficient air cooling on single-phase 220–277 V (~234–245 TH/s at 15 J/TH). Quote the Antminer S23 XP Hyd when you have hydro infrastructure and three-phase power (600 TH/s at 8.9 J/TH). Mining Man prices both by written quote from Abbotsford, BC, and ships worldwide — no public prices.

2. Who the S21 Pro+ fits
- Sites with standard single-phase 220–277 V circuits and air exhaust — no coolant loop.
- Buyers who want ~15 J/TH air efficiency without hydro plumbing.
- Small and mid fleets adding racks where noise (~76 dBA) and airflow are acceptable.
Need a different air bin? The Antminer S21++ sits at 16.5 J/TH across 216–235 TH/s bins.
3. Who the S23 XP Hyd fits
- Professional sites with three-phase power and a coolant loop (or an ANTSPACE / hydro container).
- Operators prioritizing best-in-lineup efficiency (8.9 J/TH) and density over air simplicity.
- Farms already standardized on hydro infrastructure.
4. How to choose in one minute
- Air + single-phase? Start with S21 Pro+ (or S21++ if that bin fits better).
- Hydro + three-phase ready? Start with S23 XP Hyd for efficiency and density.
- Mixed fleet? Request both on one quote — we reply with CAD or USD pricing and freight from Abbotsford, BC.

S21 vs S23 FAQ
Is the S21 Pro+ air-cooled?
Yes. The Antminer S21 Pro+ is air-cooled on 220–277 V single-phase. Typical bins are 234–245 TH/s at 15 J/TH.
Is the S23 XP Hyd air-cooled?
No. The Antminer S23 XP Hyd is hydro-cooled at 600 TH/s and 8.9 J/TH. It needs three-phase 380–415 V power and a coolant loop.
Which is more efficient?
The S23 XP Hyd at 8.9 J/TH is more efficient than the S21 Pro+ at 15 J/TH, but it requires hydro infrastructure the S21 Pro+ does not.
Where does the S21++ fit?
The Antminer S21++ is an air-cooled sibling at 16.5 J/TH (216–235 TH/s). Quote it when you want air cooling at a different bin/efficiency point than the S21 Pro+.
