Antminer R4 – SOLD OUT

Antminer R4
Antminer R4 uses a 16nm BM1387 ASIC chip, which it considers the world’s most power-efficient chip for bitcoin mining. The chip can deliver a hashrate of 8 TH/s with a power efficiency of 0.1J/GH at a noise level less than 50dB. The noise level is 52dB at an ambient temperature of 35°C. The Antminer R4 was designed to ensure the least possible sound with the maximum hashrate. It replaces the traditional miner fan with a rotary blade system that was inspired by the fan of a silent split air conditioner.

The fan’s speed is automatically controlled, so it does not produce more sound than necessary. The slim design allows the Antminer R4 to be conveniently placed on a home computer table or in a book rack. The APW5 power supply is compatible with the 220V and the 110V mains power supply in North America. On full load, the APW5 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. It can easily be fitted with 14 or 20 PCI-e connectors.
