Avalon Miner 821 - equipment for efficient mining + review of technical characteristics and payback of the new product

You will learn what equipment is needed for mining and where you can buy it. Who is the Avalon 821 ASIC miner suitable for and why is it better than the previous version? Read a detailed review of the model in our article.

Cryptocurrencies are not only a reliable and fast means of payment, but also an investment instrument with unlimited prospects. Mining bitcoins and other digital coins is a highly profitable business that surpasses the mining of precious stones and metals in its commercial potential.

Income from mining becomes much higher when using professional equipment, which increases the efficiency of the process and reduces energy costs.

We present modern mining equipment - Avalon Miner 821 , a new generation ASIC processor from the leading Chinese manufacturer Canaan , which is represented on the Russian market by New Mining .

This miner model broke all records for popularity even before it went on sale, because it combines the most valuable qualities for mining: efficiency, reliability and performance.

Cryptocurrency mining methods

For people far from digital technologies, mining is surrounded by mystery and seems to be something like the mining of the philosopher's stone by alchemists. The computers seem to work on their own in a dark room, and crypto coins are regularly “dropped” into the miner’s account.

In fact, this is a purely technical process, the essence of which is solving mathematical problems and creating new blocks of information encrypted with a cryptographic code.

At the same time, a person who wants to make money from mining does not have to be a mathematician or understand programming. It is enough to purchase computing equipment and configure it correctly.

Anyone can make money from mining, all it takes is good equipment and the right setup.

What happens next is a matter of technique. You go about your business, and the processor mines cryptocurrency. Since digital money does not physically exist, mining refers to the calculation of the code and its entry into the data ledger.

Before moving on to studying mining methods, we list the main functions of this most important process for the digital universe:

• formation of new blockchain links;
• data encryption;
• protecting the registry from hacking;
• release of new coins;
• authentication of transactions;
• support for decentralization.

As you can see, mining is a serious job on which the functionality of cryptocurrency systems depends.

Next, let's move directly to the methods of mining cryptocoins.

Method 1. Solo mining

If a few years ago a medium-power personal computer with a new video card was enough for mining, today it is becoming increasingly difficult to mine coins without special equipment.

To mine popular cryptocurrencies, you need to follow the latest developments in the technological market and periodically update your equipment, purchasing advanced miners that meet the increasing requirements for processor power and performance.

Method 2. Mining in pools

Joining pools is becoming increasingly common among miners.

The essence of a mining pool is that crypto miners unite into a single network. When a block of transactions is processed by one of the pool members, a reward in the form of cryptocurrency is awarded to all participants according to the provided capacity.

Due to the absence of boundaries in the digital space, you can join pools located geographically in different countries, having previously chosen the cryptocurrency that is most interesting for mining, since each pool is aimed at mining certain cryptocurrencies.

Method 3. Cloud mining

Despite the performance and efficiency of ASIC processors, independent mining of cryptocurrencies requires financial investments, payment of electricity bills and the purchase of additional materials and equipment to build a highly profitable farm.

Not everyone can afford such costs, so investors have found an alternative route: cloud mining. In a nutshell, this is the extraction of digital coins using acquired computing power.

Income from cloud mining is proportional to investments and is completely transparent.

The big advantage of this mining method is that the investor has no problems with setting up and maintaining the farm, as well as favorable electricity tariffs, since often companies offering cloud mining services install their farms in the territory of renewable energy sources (state district power station, thermal power plant, etc. .).

However, you should be prepared for the fact that the minimum investment amount, which can quickly pay off, will also be quite high.

We conclude: the simplest, most reliable and affordable way to start mining cryptocurrency is mining on professional equipment purchased from a reliable licensed supplier.

What equipment is needed for mining

Traditional mining on video cards and FPGAs (integrated circuits) still exists, but is gradually becoming a thing of the past. Ethereum and several other currencies are still mined on “home” equipment, but, for example, effective mining of Bitcoins – the most popular cryptocurrencies on the planet – is only possible on the latest models of ASIC miners.

There are a lot of offers on the Internet for the sale of mining equipment, but most of such equipment are outdated models of devices that have already lost their relevance due to the complication of the mining process.

Experts recommend purchasing all equipment only from specialized companies. In the Russian Federation, the leader of the specialized market is ]New Mining[/anchor]. This is an official distributor of mining equipment and a direct supplier that guarantees customers impeccable quality equipment and prompt delivery to any city and region of Russia.

Among the company's advantages:

1. A wide range of equipment for mining bitcoins and other cryptocurrencies.
2. Direct deliveries from the manufacturer.
3. Only the latest and proven equipment.
4. Almost unlimited amount of mining power.
5. Professional hosting of equipment in the organization’s data center, as an alternative to independent mining.

The company’s online store offers only the latest and most up-to-date mining equipment. A new miner model, the Avalon Miner 821, is in particular demand in 2022. This high-performance and powerful device is popular with both professional miners and newcomers to the mining market.

What is the system like at work?

We would like to reassure you right away – the system is working stably. Immediately after launch, the miner produces 7.7-7.8 Th/sec, which is even more than what the manufacturer promises. If you create a chain of several devices (maximum number of 5 ASICs), the hashrate can generally be increased to 40 Th/sec. But keep in mind that only identical miner models can be combined into a cluster. But such a chain will work without problems.

The energy consumption of the model we are considering is higher compared to the previous one, it is 1050 W (the predecessor “eats” around 850 W), but due to the proportional increase in power, the energy efficiency remains at the same level.

When the ASIC enters active operation mode, the fan operates at a speed of 5.5 thousand revolutions per minute, which quite successfully ensures normal temperatures and stable operation of the equipment. The chips inside the case heat up to about 45 degrees (at an ambient temperature of about 25 degrees, this is not much at all) and this allows you to continue working around the clock and maintain performance at the same level.

Avalon Miner 821 – a new player on the market

The new ASIC miner features increased performance and power.

The developers have eliminated all the shortcomings of previous models and made the device as reliable, economical and easy to use as possible.

1) Who is it suitable for?

Anyone who is engaged or intending to engage in cryptocurrency mining. Avalon Miner 821 is a promising and highly profitable investment that will pay off in just a few months.

2) The better than the previous model

With a performance of 11.0 TH/s, Avalon Miner 821 consumes an order of magnitude less electricity than its predecessors. The device does not take up much space and has a mandatory warranty from the manufacturer - the well-known company Canaan Creative .

At the time of writing, this is the best ratio of cost and performance of equipment for private mining.

It is not surprising that the Avalon 821 became popular among professionals even before it went on sale.

In terms of the number of pre-orders, this is the undoubted leader among other devices for mining crypto coins.

Each new miner model is almost twice as powerful as the previous one, for example, the Avalon 741 hashrate is 7.3 TH/s, and for the Avalon 821 model this figure reaches 11.0 TH/s, which is very impressive!

Let's start setting up the Avalon 741

There is no need to worry, it is not difficult. Setting up this ASIC is simple and accessible. You need to start by loading the firmware onto a flash drive. Then we connect the electronic key or, as it is commonly called, a USB dongle to the mining device, connect it to the controller and connect the latter to the network. Keep in mind that you need to turn on the miner first and only then the controller. Before you start setting up, go to the router interface, find the controller’s IP and go to the found address.

A nice feature of the Avalon 741 software is its simple and intuitive graphical interface, which even the most novice miner who is encountering equipment from Canaan for the first time can easily understand.

In the “configuration” section you will have to enter the details of the pool with which you are going to collaborate. As soon as you do everything and click on “apply”, the system will start the mining process. If you want to use fine-tuning settings, select “advanced”. The operating system is quite flexible and functional.

What to pay for - review of the technical characteristics of the new product

Nobody likes to throw money away without having actual evidence, so we present you with the technical characteristics of the new product.

The main parameters are presented in the table:

Experienced miners advise buying several miners at once to increase productivity and profits.

An even better option is to purchase several pieces of equipment and place them in the New Mining company’s data center. This not only saves energy costs, but also ensures that the miners operate smoothly and at full capacity.

Where to buy mining equipment

You will find detailed information about Avalon 821 on the New Mining Company online store website.

In addition to the new Avalon 821 miner, the company supplies other equipment for crypto mining at manufacturer prices: miners from other companies, power supplies, controllers. New Mining specialists will tell you more about the equipment, terms of purchase, payment methods, delivery times, etc. when you contact them by phone.

conclusions

Many users do not like the lack of a built-in control device with a software component for mining. However, it is precisely this feature that gives freedom of choice. You don't have to buy an expensive single board computer. You can use a router with a USB port that is lying idle on the farm.

It is the absence of a built-in controller that allows you to build a chain of Avalon 6 connected in series, which are served by only one control device. This is what allows you to quickly troubleshoot if this device itself fails, be it a Raspberry or a router. When new software versions are released, it is not necessary to update all components.

The innovative SmartSpeed ​​system was used for the first time on devices of the “home” mining class. And finally, the most important thing is that the device is of very high quality. There are no complaints about the assembly.

How profitable is it to buy Avalon Miner 821?

The main contingent of New Mining Company buyers are financially literate people who have initial capital for investment and knowledge of how profitable investments in cryptocurrency mining and the purchase of mining equipment are in the current economic situation.

Compared to other miners of equal power and performance, the Avalon 821 is much more cost-effective. And if we take into account the lower energy consumption, this model will pay for itself much faster than its analogues.

Obvious advantages of Avalon Miner 821: compactness, increased (relative to the previous model) power and a 3-month manufacturer’s warranty.

Since the equipment is designed for long-term and intensive use, such a purchase will become a source of constant profit for you for several years.

A little more about the Avalon 741 cooling system

We have already written that the main improvement in this model was the increase in productivity. This effect is achieved by the fact that, compared to the previous model, this one is equipped with a larger number of chips (88 versus 72). Such changes could not but affect electricity consumption and heat generation. These figures increased in proportion to the increase in power, so changes were required in the cooling system to prevent the device from overheating.

The new system is called Airform Cooling. Its main design difference is the penetration of air into the hottest corners and removal of heat from these hot spots. Heat is dissipated thanks to finned heatsinks located on the printed circuit board. This design makes the heat removal process more efficient - air flows stay inside the device longer, and thanks to narrow grooves on the radiators, the airflow area increases.

But to ensure a stronger air flow, the cooler must operate at high speeds, and this, naturally, increases the noise from its operation. If you are at a distance of just over a meter from the ASIC, then its noise is comparable to a loud conversation and reaches 50-60 dB.
