THELOGICALINDIAN - In the canicule back Bitmain appear the AntMiner R4 we accept wondered whether the apparatus absolutely performs as advertised After some handson time with the R4 our aboriginal consequence is that it seems to accomplish the antithesis of ability achievement and babble achievement Bitmain was cutting for
Disclosure: AntMiner R4 was provided to review.

AntMiner R4 First Impressions
The R4 and the new APW5 PSU attending like they could be an absorbing pair. From a ambit of 3 anxiety in an average-sized active allowance with an ambient temperature of 74 degrees Fahrenheit, the R4 and APW5 put out a accumulated 51 dB of noise.
The AntMiner R4 additionally runs at the defined 8.6 th/s, while accomplishing that almost quiet 51 dB. Here are the blueprint that get you to 8.6 th/s at 900 watts with 51dB:
Hash Rate: 8.6TH/s
Power Consumption: 845W 9% at the wall
Noise level: 52dB (at an ambient temperature of 35°C)
Chip abundance per unit: 126 x BM1387
Rated Voltage: 11.60 ~13.00V
Product size: 515mm (L) x 100mm (W) x 222mm (H)
Operating Temperature: 0°C to 40°C
Network Connection: Ethernet
The R4 has solid entry-level specs for mining at the accepted arrangement difficulty. What absolutely sets the R4 afar at aboriginal glance, thought, is its design. Using a cooling arrangement based on air conditioning units, the miner remained actual quiet during antecedent testing.
The advanced of the apparatus has access for the PSU and Ethernet. The PCBs are accessible on the larboard side, with the roller cooling arrangement to the right. The adapted ambassador is anon on top.
Setup is simple. DHCP is enabled, so you aloof acquisition the IP, blazon it in and access “root” for both the username and password. Once you’re in, the airheaded accredit accessible bureaucracy and operation.
APW5 PSU Adds Flexible Deployment Options
The APW5 PSU works on both 220 and 110 volts, so it is a adjustable assemblage that allows you to run one R4 on 110v, or two R4s on 220v. The APW5 can additionally can abutment up to 14 PCIe cables that, back acquainted into a 220v outlet, allows the PSU to ability two R4s. The APW5 on 110v runs up to 1300 watts, and on 220v it will run up to 2600 watts.
With a distinct ample fan on top and a cleaner autogenous design, airflow is optimized. The fan seems to absolutely circuit up alone back it gets absolutely warm. We had to put the PSU in the Mining Lab, area the ambient temperature is currently over 86 degrees Fahrenheit, to get the fan to circuit up all the way. Even in the hotter environment, while affiliated to a 220v PDU, the rig was still beneath 52 dB. This fan achievement is due to the APW5’s temperature control, which allows the fan to circuit up aloof abundant to accumulate the PSU’s temperature beneath 80 degrees Celsius, which it does well.
We aboriginal absorbed up the AntMiner R4 and APW5 in the office. Normally, this would beggarly a abrupt base blame by the appointment administrator (the wife) but in this case she did not apperceive the apparatus was running. If these low babble levels abide throughout the lifetime of the R4-APW5 combination, this rig could possibly bifold as a amplitude boiler in winter months, back you could run it central after cutting ear plugs.
That actuality said, the calefaction achievement on this apparatus is absolutely almost low, which may cut bottomward on how able-bodied it heats a air-conditioned room. In our accessible tear-down of the R4, we will booty images application a thermal cam to appearance how it disperses the heat.
Our aboriginal impressions of the AntMiner R4 and the APW5 PSU are actual positive. As advertised, at atomic initially, they are both quiet and congenital in a way that allows them to be acclimated in best settings. One of the things we would add to the PSU is a awning for the terminal spiral area. The bald breadth about them is a affair in a home ambience — if a being or pet accidentally touches the apparent piece, they could get zapped.
Overall, the AntMiner R4 and the APW5 attending like acceptable buys. As mentioned above, we will be aback in a few canicule with a breach bottomward of the APW5 and R4, so break tuned.
What are your thoughts on the new AntMiner R4 and the APW5 PSU?
