What should you consider when assembling a computer?

The time has come. You want to build your own computer from scratch, but there’s a small problem: you have no idea where to start. We’re not going to lie to you, building a computer from scratch is not an easy or cheap task.

So don’t worry if you feel lost and don’t know where to start. Here, we will explain what you should consider when building a PC.

What are you going to use the PC for?

Take a moment and ask yourself the million-dollar question: what are you going to use the computer for? Building a PC for playing the latest generation games is not the same as using it for office programs or rendering 3D models. Each case is different and requires different components. That is also the great advantage of being able to build your PC from scratch, as you can tailor it to your specific needs.

For gamers, they should prioritize above all the purchase of a powerful processor and a graphics card. Although the graphics card plays a vital role in rendering graphics, having a good processor is essential for games that heavily rely on physics or complex simulations, for example.

On the other hand, if the focus is on video editing or graphic design, you may need to invest more in RAM memory and also have a good SSD (solid state drive). As always, the final decision is yours.

Take out the calculator and do the math

We have to be clear: it is not necessary to spend a fortune on computer components that will later be underutilized. Being smart with our money will also have an impact on the PC we are going to build, since in many cases, spending more is not synonymous with it being better.

A decent motherboard

The motherboard is basically the backbone of your computer. It is where all essential components such as the CPU, RAM, GPU, and storage drives are connected. When choosing a motherboard, you must first consider the processor. This is essential because the motherboard must be compatible with the processor model you are going to use.

You should also check the number of expansion slots. Having enough PCI Express slots will allow you to expand and enhance the capabilities of your computer, for example. You should also consider the capacity and speed of the RAM that the motherboard can support; intensive tasks like gaming will require much more RAM than less demanding tasks like creating Excel spreadsheets, for example. 

Having good connectivity is also very important. Who doesn’t like having many USB ports, connections for hard drives or high-speed internet?

The key is in the processor

One of the most important parts when assembling a computer is the processor or CPU. If the motherboard is the backbone, the processor is the brain. It is responsible for executing the instructions of all the programs you use. In summary, a powerful processor will allow you to perform any task faster and better.

Choosing a good processor will also determine the overall performance of your computer, as other components such as RAM or the graphics card also depend on it. That’s why it’s important to allocate a large part of your budget to it, as it ensures that your equipment remains competent and efficient for many years.

The importance of a good RAM memory

In essence, having a lot of RAM will allow your computer to perform more tasks at the same time and with greater speed, whether it’s browsing the Internet with multiple tabs open or running heavy programs. If the RAM is insufficient, the computer generally becomes much slower. Here we advise you not to skimp on space, as the more memory, the better.

In addition to the quantity, you should also pay attention to the speed. Fast RAM increases the efficiency with which your computer works overall. By working faster, it allows the CPU to access the necessary data without delays.

Store data without worrying about space

Having enough storage space will save you a lot of headaches, especially if you are someone who stores a large amount of data (photos, videos, programs, games, etc). In addition, computers must have enough storage space for the system to function properly. A full disk will make the computer slower than usual.

Here we advise you to choose a SSD when selecting a hard drive. SSDs or solid state drives are a storage technology that offers significantly faster read and write speeds compared to traditional hard drives (HDD). This results in an operating system that boots almost instantly, programs that open in a matter of seconds, and much faster data transfer.

The graphics card

The graphics card is responsible for generating all the images you see on the screen. A powerful graphics card can, among other things, run heavy games with stunning graphics, for example. Additionally, it also helps alleviate the workload of the processor and therefore, improve the overall performance of the system.

However, it is not necessary to go crazy and buy the best graphics card on the market. Those who should prioritize it are those who play demanding video games or use video or image editing programs such as Adobe Premiere Pro or Photoshop, for example.

Don’t skimp on the source

As you can imagine, buying a good power supply is essential. This way, you ensure that the components receive a stable and efficient amount of energy, something crucial for optimal performance and overall lifespan of your PC. Low-quality power supplies can cause power fluctuations, which would end up damaging the hardware or causing unexpected shutdowns.
