The manufacturer identifies the WhatsMiner M63S as a hydro-cooled family rated at 370-400 TH/s +/-10% and 18.5 J/T +/-5%. Its product sheet specifies AC 380-480 V input. Installation must follow that exact input class, the unit nameplate, and qualified facility design.

The sheet lists an 86 x 482.6 x 663 mm enclosure including handles, 27.5 kg net weight, a custom power connection rated at 16 A or higher, Ethernet networking, and approximately 1 L of coolant per server. Its “10 kW input” notation describes the input system; the reviewed sheet does not publish a single operating-power value, so this page does not turn 10 kW into a nominal miner draw.

The liquid loop requires at least 10 L/min rated flow, pressure no higher than 400 kPa, inlet temperature of 25-55 C in normal mode or 25-45 C in high-performance mode, and +/-2 C temperature-control accuracy. The specified medium is pure or distilled water with the prescribed corrosion inhibitor and antifreeze selected for the required freezing point; the stated pH range is 7-8.7.

Firmware and recovery

M63S identifies a product and cooling class, not a firmware or recovery image. Record the miner’s reported platform, complete type, installed version, and cooling class first. If those facts conflict or are unavailable, do not select recovery media.

Confirm this unit’s platform before firmware or recovery.
After recording a matching platform, full type, cooling class, and version, review the official firmware and recovery scope.
For an unreachable unit, conflicting identity, unknown platform, or power, cooling, or liquid symptom, request WhatsMiner diagnosis.
