Bitmain Is Launching a Silent Miner and PSU to Bring Mining Back Home


Beijing-based Bitmain Technologies Limited, owner of the Antminer series of bitcoin miners, Hashnest,

Antpool and, is launching early next week the world’s most silent multi-terahash bitcoin miner

and a silent 2600W PSU specially designed for high-performance mining.


The Antminer R4 uses the world’s most power-efficient 16nm BM1387 ASIC chip for bitcoin mining. It can

deliver a hashrate of 8.6TH/s with a power efficiency of 0.1J/GH and a noise level less than 50dB. At an

ambient temperature of 35°C, the R4’s noise level is 52dB.


The Antminer R4 has been designed with great care to ensure the least possible sound with the maximum

hashrate. It replaces the traditional miner fan with a rotary blade system inspired by the fan of a silent

split air conditioner. The speed of this unique fan is automatically controlled to ensure that it never

produces more sound than is absolutely necessary. The slim design of the Antminer R4 allows it to be

conveniently placed in a book rack or computer table at home.


The APW5 power supply is compatible with the 220V as well as the 110V mains power supply in North

America. On full load, it has a power factor greater than 0.95. With a 220V supply it can deliver an

output of 2600W. It comes with seven 6-pin PCI-e connectors but can easily be fitted with 14 or 20 PCI-e

connectors. It is built for high-power performance and low noise. Like that of the R4, the APW5’s fan is

automatically controlled so it only produces as much sound as is absolutely necessary.


For home users who wish to utilize R4’s exceptional noise level with the optimum performance, Bitmain

highly recommends that they use it with Bitmain’s APW5 power supply.

With the release of these products, Bitmain hopes to bring bitcoin mining back to homes and continue

decentralizing the bitcoin mining network.
