Official exact-model reference: Bitmain documents the Antminer S19k Pro at 120 TH/s, 2,760 W typical wall power at 25°C, and 23 J/TH. Power and efficiency are ±5%. The official page does not print a hashrate tolerance or separate model code, so neither is inferred.
Electrical, physical, and environmental requirements
The official input is 200–240 V AC, 47–63 Hz and 20 A total through two 10 A inputs. Network access is RJ45 Ethernet 10/100M. Bitmain’s current PSU table associates S19k Pro with APW12 and P33-C13 and states that the cord is not included.
The server including PSU is 400 × 195 × 290 mm and 12.85 kg net. Packaged dimensions are 570 × 316 × 430 mm and gross weight is 14.5 kg.
The official ranges are 0–40°C operation, −20–70°C storage, 10–90% non-condensing RH, and altitude up to 2,000 m. Maximum operating temperature derates by 1°C per 300 m above 900 m.
Exact-name boundary
S19k Pro is distinct from S19j XP, S19 XP, S19j Pro+, and other S19-family products. Similar performance, chassis appearance, or naming does not establish the same PSU revision, controller, hashboard, firmware, or recovery route.
Firmware and recovery
Bitmain’s factory-firmware table identifies separate 7007, CV, and AML categories for S19k Pro and directs users to human support for the corresponding firmware. This proves board-specific handling, not a universal download or cross-flash path.
- Identify the exact controller and installed version before requesting firmware.
- Secure Boot enabled and Root Authority disabled do not establish a recovery medium or unlock procedure.
- For no boot, unknown board, package mismatch, interrupted writing, instability, or electrical and thermal symptoms, request Antminer diagnosis.
