SHA-256 ASIC miner for Bitcoin networks

The Antminer S9i delivers a nominal 14.5 TH/s hashrate with a ±5% tolerance across 189 ASIC chips. It connects via Ethernet and draws 1350 W at the wall. The unit is built for continuous operation in the 0–40 °C range.

Efficiency bound by 93.12 J/TH

Power efficiency is fixed at 93.12 J/TH, so total consumption scales directly with hashrate. The hash boards require three PCIe +12 V connectors each, all fed from a single PSU; mixing supplies on one board is prohibited. Ambient temperature and PSU efficiency shift actual draw.

76 dB noise from dual 12038 fans at 6000/4300 rpm

Cooling relies on a front fan at 6000 rpm and a rear fan at 4300 rpm, producing a constant 76 dB sound level. This acoustic output suits dedicated mining spaces rather than office or home environments. No alternative fan curve or silent mode is specified.

Questions about this item

What power supply connections are required for each hashing board?

Each hashing board needs all three PCI-e connectors for +12 V DC input connected to the PSU. Do not attach more than one PSU to the same board.

What are the operating temperature and humidity limits for the miner?

The unit runs from 0 to 40 °C with humidity between 5 % and 95 % RH, avoiding condensation.

How much noise does the miner produce and what fans are used?

Noise is 76 dB. Cooling uses two 12038 fans: the front fan spins at 6000 rpm and the rear fan at 4300 rpm.
