Bitmain AntMiner S7

The Bitmain AntiMiner S7 has become very popular since it was first launched in 2015. It is now in its 19th batch of production. A 28nm BM1385 ASCI chip powers the S7. 135 of these chips are spread across 3 boards and are cooled by dual fans. In case of a particular batch, a single fan will do the cooling. The metal casing has a groove system and a tongue allowing for the neat arrangement of many miners.

The S7 comes with its PSU, which is 1000W Enermax with over 80% efficiency. The S7-LN only draws about 700W, and the PSU has excess capacity even when the unit is working above its default 600M frequency.

It is recommended that the S7 should be used with the 1600 Watt APW3 power supply.

This power supply is said to be very efficient as it loses only 7% of electricity between the outlet and the miner. The APW3 needs a minimum of 205 volts to function. Unfortunately, it does not come with the needed 16A power code. It also does not come cheap at $140 but is it a great choice if you have plans to upgrade in the future as it can work with the Antiminer S9. You can also choose to use another ATX PSU that has sufficient wattage to run the Bitmain Antiminer S7.

Advantages Of The AntMiner S7

Price

The S7 has been in stores since 2015. Although it was initially priced at $2000, the price has substantially dropped. Today, you can get it at $440 from the manufacturer, Bitmain, but this cost does not include shipping costs. You can get it at a slightly higher price from online stores. The second-hand model even goes for a lower cost.

As new models such as the S9 enter the market, the price of the S7 is expected to drop even further. If you lack enough money to buy new models, you can get this model and make some profits as you wait to upgrade.

Power Consumption

Compared to the S5, the S7 is twice as efficient regarding its power consumption and only needs 0.25J of power per Gigahash. However, room temperature does determine how much power the S7 will draw. The hotter the environment, the more energy the fans will use to keep the unit cool.

Profitability

This is an important aspect for every miner. Operating a miner rig takes up a lot of costs, and it is only natural that you want a good return on your investment. If you plan to use the S7 with the regular energy that you intend to pay for, unfortunately, you will not get any profits.

However, if you have a discounted payment rate for your electricity or you know somewhere where you can mine using free power the S7 can be a good option for you and might even pay for itself and become profitable after some time.

Plenty Of Product Information Online

The S7 has been on the market for some time now. Due to its initial popularity, many users who have had an experience with it have written their reviews online. It is not difficult to find informative content on the S7. This is an advantage as you get to know what to expect from the Antiminer before using it. Newer models of Antiminers have little content online, and most buyers will buy them without any prior knowledge of how efficient they are.
