Unit prices follow the batch and the exchange rate, so we quote per order instead of publishing a fixed figure. A quote states the unit price, the dispatch window and how long it holds.
Overview
The S21 Pro sits one step below the XP in Bitmain's air-cooled ladder. At 15.0 J/TH it draws 3510 W, which is roughly 60 W per terahash lower than the base S21, so the difference shows up in the power bill rather than in the rack. Each unit is powered on, hash-tested and its board count read back before packing; the reading is tied to the serial number on the case so you can check it on arrival.
What you get
- BM1370BC chip generation, 65 chips per hash board
- Three hash boards, individually testable in the web interface
- Power-on test and hashrate reading recorded before packing
- Dual APW12 power input, PSU sold separately
