You may have heard of crypto mining and how people use their powerful PCs to mine cryptocurrency. However, if you're interested in joining the crypto mining industry, you must know that it's not as simple as installing an app on your current gaming PC.

While you can use a relatively modern computer for mining, it's still not as good as having a dedicated mining computer. So, if you really want to get started, here are some ways you can build a complete crypto mining rig that will make you money passively.

1. Buy a High-End Pre-Built Gaming PC

Mining crypto involves a lot of computing power—that means you need powerful specifications to do it effectively and efficiently. For this reason, people with high-end gaming PCs could start mining on their rigs on the get-go.

If you're planning to play AAA games and use your PC for mining when you're not using it, you should also get the best of the best. A mid-range gaming computer will not cut it, as its computational power won't be enough to work efficiently—you'll end up paying more in electrical bills than making coins.

However, pre-built computers cost a pretty penny. At the prices most GPUs go for these days, you can expect to pay a lot to get one.

2. Assemble Your Own Powerful Computer

If you already have a reasonably powerful PC, you can upgrade that instead to start mining. You don't need to have a powerful CPU. In fact, a four-core, eighth-generation Intel i5 paired with 16GB RAM should be more than enough for mining.

However, you need a top-end GPU to mine efficiently. An NVIDIA GeForce RTX 3090 graphics card that isn't hash limited will help you earn through mining. And when you're installing this GPU, you also need to match it with an equally powerful and reliable PSU.

A powerful PC can help you get started with mining, but you'll have to go beyond single-GPU setups if you want to maximize your earning potential. With the proper configuration, you can have a complete crypto mining rig that you can also use to play PC games.

3. Build a Crypto Mining Rig From Scratch

A crypto mining rig does one thing and one thing only—run the algorithm your chosen coin requires. That's why it's much more power-efficient and can generate more revenue for the user. However, you must purchase specialized parts to build a crypto mining rig.

The first thing you should have a motherboard designed for mining. A good example of this is the Asus B250 Mining Expert. This motherboard lets you have as many as 19 graphics cards on a single board, allowing you to run algorithms much faster. However, you also have to buy 19 separate GPUs, which could add up due to the sheer cost of video cards these days.

Besides the GPU, CPU, and motherboard, you also need a PCIe riser, as the motherboard can't physically handle 19 video cards installed directly on it. Instead, you'll use the riser card to connect your GPUs to the board separately.

Note that these mining rigs require a lot of power and typically run 24/7, and therefore, you'll also have to invest in a high-capacity, high-performance PSU.

4. Purchase a Dedicate Crypto Mining Setup

These rigs, also called Application-Specific Integrated Circuit (ASIC) Miners, are specially built for mining cryptocurrencies. They're like pre-built crypto miners, but they don't include GPUs. These systems are generally expensive, but they're worth the investment.

That's because you get to save time on system setup, and they're designed to run as efficiently as possible. You don't have to worry if you've added enough cooling or if you have the correct power source, as these systems already include all of them.

Points to Consider Before Mining Crypto

Whatever way you choose to build your first crypto miner, mining crypto does not always guarantee a profit. Here are some other things you should know when making a mining rig.

Electricity Costs

Crypto miners require a lot of power to run, and electricity doesn't come free. Your kilowatt-hour cost may vary from state to state, so that's one thing you should consider before getting into mining. If you want to be sure that you'll turn a profit before buying all that gear, visit CryptoCompare's calculator.

To maximize your profit, try to get the lowest electricity rates. It'll be great if you can install a solar panel system at your location that will cover your system's electrical needs. That way, you can minimize your electrical cost and maximize your revenue.

Heat Management

If you're planning to keep your mining rig inside your home or room, you must invest in a good cooling and ventilation system. This is especially true if you live in a warm location. That's because mining rigs must run all the time for you to maximize your return on your investment. And since computer systems generate heat, you must find a way to remove this heat from your area.

You'll have to invest in fans or even air conditioning to ensure you don't overheat and suffer from heatstroke while working on your mining rig. Better yet, place your mining rig in a different room so that even if the ambient temperature increases significantly, no one will be affected.

Fluctuation Risks

Most cryptocurrencies don't have economies or companies behind them. That means they tend to fluctuate based on supply and demand and the occasional tweet. If your profitability relies on your chosen currency maintaining its price above a certain threshold, then you could be in for a surprise if it suddenly falls.

For example, Bitcoin's value was around $30,000 in July 2021. It then jumped to over $60,000 in November 2021—a 100% increase in just months. However, come March 2022, its price is now at around $40,000.

So, to ensure the longevity of your operation, you should have some leeway when computing for mining's profitability. Don't base your computations on your chosen crypto's highest price. Instead, it might be good to look at its lower price in five years or more. That way, even if it drops, you're not scrambling to sell off your assets because they're no longer profitable.

Make Money Passively With Crypto Mining

Crypto mining is an excellent way to make money passively. Although the investment is substantial, you can make it back if you have a low electrical cost and an efficient mining rig. As long as you can afford the risk, mining crypto can make you good money.
