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.

Batch 12 and Batch 13 of the Antminer S9

Batch 10 and batch 11 of the Antminer S9 sold out in roughly 10 hours of launch. They were considerably stocked and so we were overwhelmed by the response again.

Unfortunately many Bitmain fans and miners missed their chance to order before the two batches sold out.

So we have good news for everyone: we are going to release two new batches!

Batch 12 and batch 13 can deliver a hashrate of 11.85TH/s and 12.93TH/s, respectively.

They will be available to order after 2300 hours (Beijing time, GMT +8) tomorrow (18 August 2016).

We suggest everybody to confirm their order here (https://goo.gl/w3G2NB) for batch 12 or here (https://goo.gl/jpvZU3) for batch 13 before they sell out.

We wish all a very happy mining experience with Bitmain.
