Let's look at the example of a home mining farm that uses the power of video cards - these are suitable, for example, for mining ether, since the highest computing hashrate is achieved precisely on graphics chips.

This farm is made up of:

A motherboard with a large number of PCIe slots to which video cards are connected. There are models that have 4, 6, 8 or even 12 of these ports. Since most often manufacturers insert slow and short slots into motherboards, you will also need risers - extension cords, to which video cards are connected.

Video cards. Preferably the latest generation, as this will allow you to mine cryptocurrency with maximum efficiency. Usually they do not save on video cards.

Power supply with high power and energy efficiency. They also refer to farm components that are not worth saving on. Power supplies with high efficiency are marked with 80 Plus Gold, Platinum and Titanium markings.

The processor, which will be enough to run the system. Farms are usually assembled on cheap and low-power processors, since they themselves are not used when mining on video cards.

Enough RAM to run the system. As with the processor, one of the cheapest sticks is usually taken to save money.

Hard drive, which can also be saved. It is enough to find one whose volume and speed will be enough for the normal operation of the system.

If we talk about bitcoin mining, then the greatest efficiency can now be achieved with the help of specialized equipment. When bitcoin first appeared, ordinary processors and video cards were used for mining - applications were run on ordinary home computers.

Soon, individual companies developed special devices tailored specifically for bitcoin mining - ASIC miners. The name stands for "Application Specific Integrated Circuit". Now almost all bitcoin mining is done with the help of ASICs.

Mining on specialized devices is more efficient both in terms of speed of calculations and in terms of power consumption. The disadvantage of such devices is that they are expensive - the cost of a new one starts from several thousand dollars.

I am sure that every miner should learn useful tools for mining, such as best mining gpu , and this will become useful
