Antminer S21+ Hyd. evidence-limited identity record
OEM-confirmed Antminer S21+ Hyd. identity record. Former 319T/358T specifications are withdrawn pending a durable exact-model manufacturer specification.
Resolve documented S21 liquid-cooled names
Exact-name boundary: these are separate named models. Do not carry firmware, recovery, control-board, power, noise, or parts assumptions from one model or suffix to another.

Evidence-limited identity record: Bitmain’s official PSU and warranty references confirm the exact name Antminer S21+ Hyd. The durable manufacturer material reviewed did not establish the 319T or 358T performance specifications currently represented by separate pages on this site.
Those bin claims and former power, efficiency, noise, dimensions, weight, electrical, coolant, release, price, lifecycle, firmware, and tuning fields are withdrawn pending a durable exact-model specification or physical nameplate evidence.
What is confirmed
The current manufacturer PSU table associates S21+ Hyd. with APW111721c and LP20. This is a narrow accessory reference, not a facility specification. It does not establish voltage, phase, current, coolant chemistry, flow, pressure, connector, control board, firmware, or recovery medium.
Do not collapse nearby hydro names
S21+ Hyd., S21 Hyd., S21 XP Hyd., and S21e Hyd. are distinct names. A plus sign and cooling suffix are part of the identity. Do not transfer a PSU, hashboard, controller, firmware package, coolant procedure, or facility design between them.
Evidence required before installation
Collect the complete nameplate, exact manufacturer document revision, PSU label, input rating and phase, controller marking, coolant connectors, and installed version. Do not use a reseller title, calculator entry, or similar image as installation evidence.
Firmware, recovery, and repair
- Record the exact suffix, board, PSU, and installed version.
- Do not select an S21 Hyd. or S21 XP Hyd. package by analogy.
- For no boot, conflicting identity, coolant alarms, leakage, corrosion, instability, or electrical and thermal symptoms, request Antminer diagnosis.
