How to build a cryptocurrency mining rig

Cryptocurrency mining involves the use of a computer or multiple computers to validate transactions on a blockchain. Technically, these computers solve cryptographic equations and record data in a digital ledger. The more computers solve equations, the faster the blockchain can validate transactions.

When miners verify unconfirmed block hashes, they receive a reward for each verified hash. Mining can be power and computationally intensive, requiring specialized hardware and crypto mining software.

Among the most mined (and most profitable) cryptocurrencies are Bitcoin (BTC), Monero (XMR), Ravencoin (RVN), and Dogecoin (DOGE). ether (ETH) used to be part of this list, but Ethereum has recently switched to a proof of stake (PoS) consensus algorithm, which means that ETH can no longer be mined.

Comprehension Cryptocurrency mining is vital for those who want invest in cryptocurrencies. After all, miners play a critical role in ensuring the security and decentralization of blockchains. Cryptocurrency mining is a process that requires the use of hardware, software specialized in cryptomining and a mining pool. The process can be difficult to understand and set up without proper guidance, so here are some essential details to get you started.

What is a cryptocurrency mining rig and how does it work?

A mining “rig” is a customized personal computer (PC) that contains all of the standard PC components: CPU, motherboard, RAM, and storage. The main difference is that mining rigs use graphics processing units (GPUs) instead of central processing units (CPUs).

GPUs are better at solving the cryptographic equations needed to verify transactions on a blockchain. A single high-end GPU can outperform a standard CPU by up to 800 times in terms of instructions per clock. This makes them essential for anyone looking to mine cryptocurrencies.

GPUs also have much higher hash rates and are easier to maintain, making them a popular choice among miners. Hash rate is a measure of how fast a computer can solve cryptographic equations and is used to determine the profitability of mining.

Another key difference is that mining rigs are often equipped with multiple GPUs. This is necessary because the more GPUs a platform has, the higher the hash rate. Cryptocurrency mining rigs work by using GPUs to verify transactions on a blockchain.

It is also worth noting that not all miners use GPUs. In some cases, such as Bitcoin mining, miners may prefer to use an Application Specific Integrated Circuit (ASIC) instead.

Some things to consider when looking to build a mining rig are:

  • The cost of the equipment: GPUs and ASICs can be expensive, so it is important to consider the prices of all the necessary equipment.
  • The cost of electricity: Cryptocurrency mining is an energy-intensive process, so it is essential to consider the cost of electricity.
  • Trial and error: Building a mining rig is not like building a custom PC; it can be a trial and error process involving many changes and adjustments.

What components are required to build a mining rig?

Several key components are required to build a mining rig. These include:


As mentioned above, GPUs are the critical component of any mining rig. The number of GPUs required will depend on the hash rate you are looking to achieve. But one or two GPUs should be enough for someone just starting out.


ASICs are specialized machines that are specifically designed to mine cryptocurrencies. They are typically priced higher than GPUs but offer much higher hash rates.

The motherboard is the backbone of any computer, and a mining rig is no different. It must be compatible with all GPUs that will be used on the computer.

Some beginners choose to mine only with CPU, which is also possible. However, they must be high-end, capable of meeting mining demands. When using GPUs for mining, an entry-level rig only needs a low-end or moderate-end CPU, such as an 8th or 9th generation Intel.

Random Access Memory (RAM) is essential to any computer as it is used to temporarily store data while the computer is running. For a mining rig, it is important to have enough RAM to store the data from all the GPUs used on the rig.

The power supply unit (PSU) is one of the most important components of a mining rig. This is because the power supply must be able to provide enough power to all the components in the platform. A good rule of thumb is to get a power supply that can provide at least twice the power your equipment will need. Typically, a 1200W platinum-rated power supply will work just fine.

As with any other computer, a mining rig needs some storage. This can be in the form of a hard drive or SSD. The size of the storage will depend on the amount of data you plan to extract. Generally, any drive that is 240GB or larger should do the trick.

Other requirements

In addition to the hardware components listed above, a few other things are needed to build a mining rig. These include:

  • Mining software like CGMiner, EasyMiner or BFGMiner;
  • An operating system such as Awesome Miner, Rave OS, or Hive OS;
  • A crypto wallet to store your mined coins;
  • A riser to raise your GPU to increase airflow;
  • A stable Internet connection; Y
  • A flash drive with at least 5 GB capacity.

How to build a mining rig: for beginners

Now that we’ve discussed the components needed to build a crypto mining rig, it’s time to put one together. Here is a quick step-by-step guide:

Step 1: Connect the motherboard

Make sure the lever that secures your CPU socket is in the released position. Next, place the motherboard outside of the mining frame on top of something that will keep it static-free, like a foam box or anti-static bag.

Step 2: Connect the processor

Connect the processor to the motherboard. Create a mark on both the CPU and motherboard sockets to identify which is which later. Also, be careful when connecting the CPU pins to the motherboard as they can easily bend and damage the entire processor.

Step 3: Install the RAM

Inserting a RAM module into a motherboard’s RAM socket is very simple. Carefully push the RAM module into the RAM socket after opening the brackets on the sides of the motherboard slot. The RAM must be installed in the correct orientation and care must be taken when doing so, as the RAM can only lock into the socket one way.

Step 4: Connect the power supply

Make sure to connect the power supply to the motherboard securely; otherwise the mining rig will not be able to start. The CPU’s 8-pin power connector should go into the motherboard slot closest to the processor.

Step 5: Connecting USB risers

These are required to connect the GPUs to the motherboard. Insert them into the available PCI slots on the motherboard.

Step 6: Attach GPU

Secure the GPUs in the frame using USB risers. Then connect the PCI-e 6+2 power connectors to the GPUs. Lastly, double check that all cables are properly plugged in before starting the mining rig. Once everything is plugged in, you are ready to start mining cryptocurrencies.

Is crypto mining still profitable?

now that Ethereum has eliminated mining coupled with its switch to a PoS mechanism, can mining still be profitable? The answer is yes, depending on a variety of factors.

The profitability of mining varies from one cryptocurrency to another. For example, Bitcoin mining is still very profitable, while Ethereum mining has become much less profitable. Another factor to consider is the price of a cryptocurrency. If the price of a coin goes up, mining that coin becomes more profitable and vice versa. Cryptocurrency mining can still be a profitable endeavor, but it is crucial to do your research before you begin.
