Bitmain Antminer A3 (815Gh) is another one from Bitmain Company, and this one uses the Blake2B algorithm. With a maximum hash rate of 815 Gh/s and power consumption of 1275W, it promises to deliver exotic coins. What you get from this miner are the SiaClassic and SpaceCash coins, which are profitable. The coins are mined with a special algorithm and low efficiency. What sets this apart from other miners in the Blake2B category is the low power consumption. The miner was released in January 2018.

Characteristics and Features of Bitmain Antminer A3 (815Gh)

What makes this miner different from others is the weight as it weighs more than other units. The weight of this miner is 4.2Kgs, and the size is 125*208*321mm. It uses the Ethernet interface and comes loaded with a voltage of 11.60V minimum and 13.00V maximum. The top coins to mine with this unit are SiaClassic and SpaceCash. Others prefer to use this miner to mine Mining Rig Rentals under Blake (2b) algorithm.

The miner is fully ASIC supported, which means you can monitor the equipment’s progress. You don’t have to wait as miners can track the mining from anywhere. Some reputable mining pools come highly recommended by this miner. These mining pools include AntPool, F2Pool, Luxor, NanoPool, and SiaMining. Miners can get their hands on this unit from the manufacturer or selected stores.

Algorithm of the Bitmain A3 815 Gh/s

Blake2B algorithm is explicitly used to mine exotic coins from the Sia family. With this algorithm, you get a miner that comes with three chipboards. It has a chip count of 180, and the chip’s name is BM1720. There’s no information on the chip’s size, but we believe it’s the same as other Bitmain chips. It also comes with 10*6 pins and, as earlier indicated, uses the Ethernet interface.

Efficiency of the A3 815 Gh/s Bitmain Miners

0.002j/Mh is a low-efficiency rate as most Bitmain miners come with higher efficiency. Miners should note that the low efficiency is due to mining just a handful of coins. The manufacturer was trying to cut down the cost of mining. One can note that the power consumption is below what Bitmain miners offer. Power consumption of 1275W is one of the lowest in the industry. It becomes apparent that this is a miner for choice as electricity cost is low.

Hash Rate of Bitmain A3 (815Gh)

815 Gh/s is the hash rate that comes with this miner. The hash rate is also low compared to other Bitmain products. With this hash rate, users can mine two exotic coins effectively. Competitors of this miner don’t have this hash rate, which goes to show growth in technology. Bitmain as a manufacturer has proved time and again that they are ahead in the Crypto mining field. The hash rate is enough to give miners profitable SiaClassic and SpaceCash coins.

Humidity and Temperature of 815 A3 Bitmain Miners

The humidity and temperature settings play a vital role in ensuring the unit works effectively. And this is why the manufacturer has given certain conditions to these two features. The minimum set humidity for this unit to work effectively is 5 percent. 90 percent is the maximum set humidity settings. For temperature, the minimum is 0 degrees centigrade, while the maximum is 40 degrees centigrade.

Noise and sound capabilities

76 decibels is what the miner brings to the table as the noise level. With these decibels, you can easily use the miner at home for mining. You can also opt to invest in large-scale mining for this unit. There won’t be any noise complaints from neighbors as the unit is environmentally friendly.

The Profitability of Bitmain A3 (815Gh)

As with all miners, the profitability is obtained after factoring in a few details. You have to know the coin prices as well as electricity rates in your area. When the market favors these coins, mining is extremely profitable with this miner.

Warranty of the A3 815 Gh/s Bitmain

With the miner being a limited unit, the warranty is often less than 30 days.
