As computing technology advances at a rapid pace, the number of components in a gaming PC continues to increase at an even faster rate. This, combined with a more complex design, makes building a new PC more complicated than ever. Today, enthusiasts can choose from an array of components to fit their needs, but in 2021, you won’t have the same options. As such, we will use the term “PC” to refer to a gaming PC, from now on.

Building a gaming PC these days is no different from building a PC for any other purpose. When you shop for one, there are no crazy electronics or computer parts that will cause you to break your budget. You will simply need to pay attention to the prices of all the parts and add them up. That’s it.

The year 2021 will mark one of the most significant years in the history of personal computing. The average computer is more capable and affordable than ever before, but with almost every new release, there is always more to do—and that’s a good problem to have. The same is true for PCs too. While computer prices are continuing to fall, desktops are still delivering the power and capabilities that users demand. While the latest models should be able to do the same things as the older models—and sometimes more than that—with only a moderate increase in power.

Are you fed up with pre-made setups? I mean, how could you not be? You know, we’ve all been there. The vendors pressurize us into purchasing prebuilt PCs, which are time and effort consuming. The PC eventually dies after a year or two, and the cycle repeats. To stop this cycle, I’ve given you something so important that it will spare you the trouble of having to purchase new computers on a regular basis. Yes, this is the definitive answer to the question, “How much does it cost to construct a gaming computer?” The simple answer is that it may cost anything from $300 to $2000. It is completely dependent on the components used and the cost associated with them.

It goes without saying that constructing a PC from the ground up may be intimidating and time-consuming, especially when learning all of the subtleties and regulations that go into producing a great PC. But bear with me! If you can construct a PC from the ground up, you will be future-proofing it for at least three years. Why? What’s the big deal about making it yourself? To begin with, while constructing a PC yourself, you take into account all of the characteristics of each component. You compare the specs to a variety of goods. See, you’re spending your time in self-education, and what do you receive in return? -A faultless PC that will last for years!

An explanation of pre-built rigs and why they should be avoided at times.

I don’t intend to say that you should shun pre-built setups like the plague. You know, they’re fine and totally acceptable at times, but they’re not always. It’s because a seller only has a restricted amount of goods. They may compel you to purchase an i5 7th generation CPU and a GTX 1060 3GB graphics card. This may result in a bottleneck, meaning that performance will be severely limited as a result of the mismatched component need. See, this is why you should be designing a bespoke computer from the ground up to avoid the horrible truth of being powerless in the face of bottlenecks.

Breakdown of the components

A PC is made up of several parts, the most important of which is the motherboard. On the MOBO, you may install various components such as the GPU, CPU, fans, hard drives, SSDs, RAM modules, WIFI card, and so on. What’s the catch, though? Why am I included all of these elements? Well, the purpose for doing so is to raise awareness of component cross-compatibility. Isn’t it true that you can’t utilize an Intel Core i9 10900K with a GT 730 GPU?

As a result, there is no simple answer to the issue of how much does it cost to construct a good gaming PC. It might cost $2000 for you since all of the components are high-end, but it could easily fit into the $300 range for someone else. It’s extremely individual and depends on the user.

The Computer Processor (CPU)


“The CPU is the brain of a computer,” goes the old adage, and it’s completely true since the CPU enables you to communicate TO and FRO with both programs and hardware. Let’s pretend there’s a CPU with reduced processing power. So, what do you think is going to happen? Applications will take longer to execute and communication between components will be slower. You’ll need a quad-core, hexa-core, or octa-core CPU to do this. You can obtain a core count of 24 with AMD’s new Threadripper series, but such processors aren’t advised for gaming; instead, choose a CPU in the center of the range.

Computer Graphics Card

Because both are needed to operate games and apps, a GPU complements a CPU. As you go up the stairwell, you’ll see that GPU prices increase since they either have a massive amount of VRAM or are from a renowned brand. Whatever the case may be, you must be mindful that the GPU must be capable of matching the processor’s processing capability. Anything less or more than that will result in bottlenecks. I would suggest a GPU from the intermediate rung for about $200-$500. Anything beyond this should be done at your own risk.



It’s possible that you’ll have to make a budget sacrifice in this situation. For starters, if both the CPU and GPU are high-end, the motherboard will inevitably be as well. Anything under $200, on the other hand, would suffice. But here’s something I’d want to tell you. All of the components are housed on the motherboard, which is an important component. You can’t build a PC without it, particularly a powerful gaming PC. As a result, make sure your motherboard includes all of the capabilities you need, like Bluetooth and WIFI compatibility, M.2 and NVMe ports, and USB gen XYZ slots.

Also, the VRM (voltage regulator) should be excellent since most devices lack one, which is a disappointment for people who want to overclock their CPU and GPU.

Keeping things in storage (HDDs and SSDs)


Traditional hard drives are loud and have slower transfer speeds, so I wouldn’t suggest purchasing them. Instead, look into SSDs and NVMe, which are much quicker than traditional storage systems. Furthermore, SSDs are favored for quicker boot and load times; therefore, a 120GB SSD is recommended for simply installing Windows and keeping essential programs. Because SSDs are so costly, you can utilize HDDs to store games.

RAM (Random Access Memory) (Random Access Memory)


You can get by with 16 gigabytes of RAM for gaming purposes. A good kit will set you back about $90, so plan accordingly. When it comes to the significance of RAM, it’s a must-have for storing data temporarily. The CPU and GPU continuously update the game on your screen by transacting data from the RAM. It isn’t required that it be a game. Any program will accomplish the same thing.

Electricity (PSU)

Believe me when I say that I’ve seen PCs burn to cinders just because they utilized a local power supply. When it comes to choosing a power source, few individuals do their homework. You should be aware that your motherboard is powered by a power supply unit (PSU). There will be voltage spikes if you purchase a defective power supply. Because this anomaly may harm your motherboard, always pick a recognized brand of power supply (power efficiency of 80+ is a must/bare minimum).

Also, I would recommend setting aside $100-150 for a high-efficiency power supply.

PC Case

When you’ve finished purchasing all of the main components, it’s time to start looking for a decent PC case. There isn’t a set pricing range since the price varies on the form factor you choose. If your motherboard has a micro-ATX form size, you should look for a PC case that has the same form factor. So, for a PC case, maybe a budget of about $100. Aside from that, make sure your case can handle fans and has unrestricted airflow. The temperature of your components will stay below the maximum threshold as long as there is ventilation.

Enlisting a price for these key components

  • CPU price ranges from $200 to $700. (mid-to-high end product)
  • GPU= a maximum of $700
  • RAM costs about $100.
  • PSU = maximum of $150
  • Within $300 for SSDs and HDDs
  • Motherboards cost between $200 and $300.
  • Maximum $100 for a computer case

Other elements to think about

  1. Monitor: Without a monitor, you won’t be able to use your computer (in terms of the display). In other words, if you don’t have a display, your computer is useless. I would suggest a 60Hz monitor, but if your PC is high-end, 144Hz would suffice. A budget of $300-500 would be ideal.
  2. Peripherals: In order to construct a gaming PC, you’ll need a keyboard and mouse. You can’t actually pass instructions in without them. Additionally, for smooth typing performance, invest in a mechanical keyboard (a bit more costly than conventional membrane keyboards). In terms of the mouse, any model will do as long as your grasp isn’t distorted. Also included in the peripherals are speakers, so if you don’t want to spend money on headphones, choose a cheaper speaker. I don’t think any of these will set you back more than $300.
  3. Gaming desk: This is an optional item, so I won’t pressure you to get one. However, your computer should have some kind of support. Would you really want to use your computer on the ground? As a result, it’s preferable to acquire a low-cost gaming desk (preferably custom-made) for your PC.
