Choosing a miner

How do I choose the right miner?

Start with the practical limits: the power you have available (voltage and amperage), the space and ventilation, and how much noise you can live with. Then compare the specifications on each product page, mainly hashrate, power draw and the algorithm or coin the machine is built for. If you are unsure, send us your setup details and we will tell you honestly what will and will not work.

What do hashrate and power consumption mean?

Hashrate is how many calculations per second a miner performs, shown in units such as TH/s (terahashes per second). Power consumption is the electricity the machine draws, in watts. Dividing power by hashrate gives efficiency (J/TH), where a lower number means the machine uses less electricity for the same work. Hashrate figures only compare machines built for the same algorithm.

What is the difference between 220-240V and 380-415V miners?

This is the supply voltage the machine is built to run on. 220-240V models plug into a single-phase supply, as found in many homes and small sites. 380-415V models are designed for three-phase supply, which is common in larger commercial and industrial sites. Always check the voltage range listed on the product page against the supply you actually have, because a machine will not run safely on the wrong one. A qualified electrician should check your wiring and circuits before you install anything.

Is an air-cooled or a hydro (liquid-cooled) miner better?

Neither is better for everyone. Air-cooled miners are simpler to set up and need only airflow and space. Hydro miners move heat into a liquid loop, which usually means much quieter operation at the machine and a more compact layout, but they need a suitable cooling system, such as the equipment in our Hydro Cooling category. Which one suits you depends on your site, your budget and how much setup you are happy to take on.

How loud are ASIC miners?

Air-cooled ASIC miners are loud because of their high-speed fans, often comparable to a vacuum cleaner running continuously. They are generally not suited to living spaces. Hydro miners and small home miners are quieter. Noise levels, where the manufacturer publishes them, are listed in the product specifications.

Are there small miners suitable for home or solo mining?

Yes. Our Home Miners range includes compact, low-power devices such as Bitaxe, NerdMiner and Lucky Miner. They run on ordinary household power and are quiet, and they suit hobbyists who want to learn or take part in solo mining. They are far smaller than industrial ASICs, so treat them as a hobby device and read the specifications to understand what they can do.

Parts and compatibility

How do I know a replacement part fits my machine?

Check the exact model of your miner (usually on the label on the unit or in its control panel) and compare it with the compatibility details on the part’s product page. Power supplies, control boards and fans are often specific to a model or family. If the page does not make it clear, send us your miner model and the part you are looking at before you order, and we will confirm.
