Before we begin, it is essential to understand that bitcoin mining for profit is very competitive. Also, the volatility in bitcoin prices makes it very challenging for you to realize monetary gains. Recent years has increased the number of bitcoin miners making it more and more difficult to mine bitcoins. Unless you have a lot of infrastructure mining only makes sense if you plan to do it fun and you are not so much interested in making a profit.
Tips for Building Your Own Bitcoin Mining Machine
What Bitcoin Mining is
To build a bitcoin mining machine, you must first understand what it is. Primarily bitcoin mining can be considered as a giant lottery where you compete with other miners to earn bitcoins. Faster hardware can make more attempts per second to gain bitcoins while the bitcoin network adjusts itself continuously to keep the rate of finding a winning block has to every ten minutes. In essence, mining bitcoins secure transactions in the network and records them in a bitcoin public ledger known as a blockchain.
What you will need to build BTC mining rig
You will need to pick out the parts for a bitcoin mining rig which include;
Graphics cards (GPUS) for mining – when it comes to selecting GPUs, it is crucial that you pick the bang for the buck. Look for something with low power usage, high hash rate and low cost. When you are starting, you can go for as little as 1 GPU or up to 7 GPUs within one rig. In regular instances since 7 GPUs is very
difficult to make stable, most people result to 5-6 GPUs in a mining rig. The most optimal balance is to have a GPU with a high hash rate while having lower power consumption. Examples of these GPUs include the NVidia GTX 1080Ti and the AMD Vega RX 56.
The case – you can build your custom mining rig case. Another option is buying a milk crate or a plastic storage crate. Either of the options can work equally as well, however, having a custom built case looks better.
1200w+ Gold certified power supply – bitcoin mining consumes a lot of power. A typical desktop computer consumes around 300W-500W. However, when mining and you are powering up to 6 GPUs, you have to ensure that your power supply is reliable. You will be looking for 1200W+, and also its efficiency has to be gold certified or better. Having modular power supplies helps you to configure your cables individually. This goes a long way in building out your rig. Another option is to use dual power supplies. This way you will put to use an adapter cable such as Thermaltake cable.
Motherboard + CPU combination – when it comes to bitcoin mining you will want to maximize the number of GPUs that can be supported by your motherboard. Unlike the ordinary 1 0r 2 GPUs that a desktop computer can support, your motherboard should support up to 6 or 7 GPUs. Such motherboards are difficult to find in most stores. You will need to shop for them online. When it comes to the CPU, you only require something basic like Celerons. Your RAM should be 4GB DDR3 1600Mhz.
Power riser cables – Another thing that you will require are the powered riser cables to allow you to mount the GPUs within the case or case. You need to have riser PCI cables to extend the PCI-e connection from the motherboard. It is necessary that you get as many power riser cables as you can to match up with the GPUs you have.
SSD hard drive – you will need just a basic 120GB SSD drive for installing the operating system and running your mining software.
Accessories – a basic monitor and keyboard/mouse combination is required to configure all the mining software and settings.
Box Fan – to prevent over heating you require a box fan per rig.
Operating System – you can operate on either Windows or Linux operating systems. More preferably the EthOS of Linux or Windows 10.
