Bitmain Launches Antminer R4, the Most Silent Multi-terahash Bitcoin Miner, for Home Use

Some people hang photos of their family on their office walls. Others, might place trophies, diplomas or that huge fish they caught during their last fishing trip. Us, we’re Bitcoin miners. We finally have a miner that belongs on our office desk.

We are launching at 23:00 (GMT+8) on Monday (29 August) 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 centrifugal fan 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.

APW5 power supply unit (PSU) for bitcoin miners

The APW5 power supply

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 pairs of 6-pin PCI-e connectors but can easily be fitted with upto 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, we 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.

  1. Is Antminer R4 come with power supply or need to purchase separately? Can R4 connect to APW3 ?

    • Hello Tan!

      Thank you for reaching out and for expressing interest in the R4 miner. The R4 does not come with its own power supply. Yes, the R4 can work with the APW3 power supply just like previous miners. However, to make the most out of your R4 miner, we highly recommend the APW5 power supply.
