Antminer HHB42701 1U Hydro Bitcoin Miner – 49.75 TH/s, Single-Phase Power

Antminer HHB42701 — 49.75 TH/s in a 1U Hydro-Cooled Format

Antminer HHB42701 combines 49.75 TH/s of SHA-256 mining performance with a slim 1U chassis, hydro cooling and a single-phase power supply configuration. With specified wall power consumption of 1366W at 35°C, it provides clear operating parameters for planning rack space, electrical capacity and cooling requirements.

This configuration is intended for Bitcoin mining installations with an appropriate external water-cooling system and wired network connection.

Compact 1U Design for Rack Deployment

The HHB42701 measures 360 × 422 × 43 mm. Its low-profile chassis supports organized equipment layouts where vertical rack space matters.

For multi-unit installations, allow space for power cables, water connections, network cables and maintenance access. Check rack mounting compatibility before installation.

Single-Phase Power Configuration

The specified APW8-3 power supply configuration uses single-phase AC input. This is relevant for sites planning mining deployments around single-phase electrical infrastructure.

Before installation, confirm the actual power supply’s input voltage, connector requirements and circuit capacity. Single-phase operation alone does not establish compatibility with every household socket.

Hydro Cooling with Defined Operating Requirements

The HHB42701 uses water cooling to transfer heat into an external cooling circuit. The supplied specifications list:

• Recommended inlet water temperature: 35°C
• Water flow rate: 2 L/min ±10%
• Water pressure limit: ≤3.5 bar
• Ambient operating temperature: 0–40°C

These values help buyers assess whether their cooling system can support the miner. For multiple units, size the shared cooling system according to total heat load and hydraulic requirements.

Clear Power Consumption for Site Planning

The specified wall power consumption is 1366W at 35°C, with a listed efficiency of 27.45 J/TH.

At a constant 1366W, one miner would consume approximately 32.78 kWh over 24 hours. This calculation excludes any external cooling equipment powered separately.

Estimated daily electricity cost can be calculated as:

32.78 × your electricity price per kWh

Actual consumption depends on operating conditions, configuration and supporting equipment.

Antminer HHB42701 Technical Specifications

Specifications describe the listed configuration. Confirm the supplied unit, accessories and operating requirements before ordering.

Who Is This Miner Suitable For?

The Antminer HHB42701 is an option for buyers who need a compact SHA-256 miner and already have, or plan to install, suitable hydro-cooling infrastructure.

Potential applications include:

• Rack-based Bitcoin mining installations.
• Mining sites using single-phase electrical infrastructure.
• Hydro-cooling test and integration projects.
• Multi-unit deployments where rack space and cooling layout require careful planning.

With a listed noise level of 67 dBA and an external cooling requirement, installation should be planned for a suitable equipment area.

Frequently Asked Questions

What is the Antminer HHB42701?

The Antminer HHB42701 is a 1U hydro-cooled SHA-256 miner. The listed configuration provides 49.75 TH/s with wall power consumption of 1366W at 35°C.

Does the HHB42701 use single-phase power?

Yes. The supplied specification lists an APW8-3 single-phase power supply configuration. Confirm input voltage, wiring and circuit requirements for the actual unit before installation.

Does it need an external water-cooling system?

Yes. The miner requires a suitable external cooling circuit. The listed operating parameters include a recommended inlet water temperature of 35°C, a flow rate of 2 L/min ±10% and a water pressure limit of 3.5 bar.

How much electricity does it use per day?

At a constant wall power of 1366W, calculated consumption is approximately 32.78 kWh per day. Separately powered cooling equipment adds to total site consumption.

Can it be used for solo Bitcoin mining?

Solo mining depends on the installed firmware and compatibility with your chosen solo pool or node setup. Confirm this configuration before ordering. Solo mining rewards are probabilistic and are not guaranteed by the miner’s hashrate.

Is 6.5 kg the net weight?

No. The supplied specification lists 6.5 kg including packaging.
