How to build a PC: Tools and choice of accessories

No doubt that the assembly of a computer can become one of the most exciting experiences. While it is a complicated process, it is not necessary to be an expert to carry it out, nevertheless clearly that we must carry on with the utmost care. Here we tell you all the steps to achieve it.

There are several reasons why many users choose to build with its hands their own PC. Note that the assembly of a computer is no longer as difficult as it was years ago, so it is a task that anyone can undertake without practically problems.

Mounting a PC from scratch brings us a lot of benefits. In principle costs, because the fact is that the construction of our own equipment are significantly cheaper than buying one preassembled. In addition with the same budget we can access a truly superior computer to the offered in the store, and we can even choose to purchase high quality components.

On the other hand, a PC built by us can be easily customizable, upgradeable and even upgradeable, which will bring as many years of life of the equipment. Let’s not forget also, when we assemble our own PC, at the same time we are learning a lot about the hardware.

Very well, if you’ve decided to build your computer, here are some tips and steps to achieve your mission properly.

It is noteworthy that before starting to assemble the team, we must put on an anti-static wrist strap to prevent static electricity discharges on the components, which can irreparably damage the parts of the equipment.

We can also discharge any static electricity produced by our body by land, for example, maintaining contact with a metal component cabinet.

Another fundamental aspect is to look after the area in which we will work, since it must be large enough to allow us to move comfortably, and also allow us to place on a flat surface the different elements to be used during assembly. Ideally, work on a wooden surface.

Also is extremely important that before you start assembling a computer, we carefully read all the manuals provided by the manufacturer of each component, so as not to damage them during assembly.

The elements used

About the work area must have not only the cabinet and the various internal components that build up the new PC, but also must have available the following items:

  • Multistep screwdrivers and sizes
  • Some additional screws
  • Cleaning cloth
  • Isopropyl Alcohol to clean
  • A small plier long tips
  • A flashlight (optional)

Before starting the assembly, it is advisable to clean the components and the various surfaces of the cabinet with cloth and isopropyl alcohol, to remove any accumulated dust and dirt.

Choice of accessories

Once we have all the essential elements of the future PC, i.e. CPU, Motehrboard, RAM, video card and hard disk, then it is time to start choosing the cabinet or box containing all these elements.


In general, a variety of very good cabinets at very low prices currently on the market, of course we can also choose to purchase a brand known cabinet, but we must bear in mind that when dealing with high-end products, its value will be much higher.

It is also important that we choose a cabinet that includes plenty of islands to add several hard drives and optical disk drives, because it is possible that in the future we desire to incorporate more than one of these elements.

With regards to the connectors where we will plug the microphone, headphones and speakers, the ideal is that they are located in the front of the cabinet, as this will give us easier access to switch audio devices.

Choosing optical drive

While the DVD drive is not as important today, as they have been replaced by memory cards and pen drives, is likely that we require a CD/DVD drive to install the programs and the operating system.

By acquiring an optical drive, we can also come to consider buying a modern product that includes Blu-ray technology. While it is true that Blu-ray drives are significantly more expensive than DVD, keep in mind that a unit of this type will be a step further in technology, also it will allow us to play movies and other videos in high definition.

It is important to mention that when it comes to external storage, an excellent option is to use memory cards, which although they are more expensive, provide greater physical security to stored content.

In addition we note that today almost all devices we have at home usually include an SD card, so an excellent option is to add to the PC we’re building a 3.5 module with card slots, which can be located in the cabinet spaces available for HD or CD/DVD drives.

The last but not least

It is desirable that in the list of sourcing for our PC we include some more items that will be critical to enjoy the computer. This is where we must choose peripherals and accessories that accompany the computer:

Wi-Fi card or adaptor: We can choose to include in the PC case an Wi-Fi internal board, or add an external device such as dongle. More about that here.

Microphones: According to the use that we think give this peripheral, we can choose to purchase a cheap mic or choose something more expensive that allows us to make high quality recordings. Find more information here.

 Speakers: The quality and cost of a pair of speakers depends exclusively on the use we will give, as well as the budget we have available. They are indispensable for videoconferencing, watch videos and play music.

Webcams: is a fundamental device if we use the PC to communicate via video, so we invite you to read more information here.

Another accessory that should not be overlooked is the acquisition of a power stabilizer, as it will help us to protect the computer from fluctuations in the power supply.

Finally, and no less important, is to choose the operating system you install on brand new PC. But for this, we must first assemble the team, so get to work!

How to build a PC: Assembly Step by Step

Although it seems an incredibly difficult task, build a computer from scratch is a task that if we start with patience and a little knowledge, we can do it without any inconvenience, although our knowledge in computers is basic.

Mounting a PC from scratch brings us a lot of benefits. In principle the costs. There is no doubt that build our own computer to be significantly cheaper than buying one pre-built. In addition with the same budget we can access a truly superior computer than those offered in stores, and we can even choose to purchase high quality components. It is why in this article we will find all the necessary steps to build a PC, including safety instructions and tools needed to undertake the task.

How to build a PC

Before beginning, we must ensure we have the right tools for the task. Fortunately, tools are not difficult to obtain, since it most likely is that we have at home.

  • Screwdrivers (multiple sizes and types)
  • Some additional screws
  • Cleaning cloth
  • Isopropyl Alcohol to clean
  • Long-nose pliers
  • A flashlight (optional)

Once you have collected necessary, it is time to start.

Step 1: The power supply

In principle, if we have acquired a cabinet that did not include power supply, the first step is to mount the power supply case to the chassis of the cabinet. This we must do considering that the fan points away from the box, to the rear of the cabinet, and that the color cables facing inside of the box. Once placed, it must be fastened with screws.

Step 2: Install the processor

Although it is possible to install the processor once the motherboard be attached to the chassis of the cabinet, it is best mount the processor before fixing the motherboard on the chassis

First thing we do is identify the socket where the processor which is readily detectable be located, as usually it is large and has several circular holes, in addition to the indication of the acronym ZIF.

The correct location of the processor will be defined according to the alignment of the slot. The CPU has a mark in one of its corners that allow us to put the processor correctly. Obviously this mark must exactly match the one that has the socket.

How to build a PC

Carefully put the processor on the socket, and without exerting much pressure we insert the pins of CPU into the slots socket. For this we do not force, just let the CPU “fits” into the socket. In the event that this does not happen, possibly are due to the processor has some of its bent pins, which can straighten carefully with the help of a flat screwdriver.

Then, move down the socket lever, for that the processor is firmly attached to the motherboard.

Once the task is finished, and only if the processor does not include factory sink, we mount one on the CPU, through the anchors that includes the socket. It is likely that before placing the sink, we need distribute thermal paste with fingers, carefully to form a thin film on the processor, avoiding that too much pasta to accumulate, and then just be able to place the sink.

Anyway it is always advisable to purchase a processor that includes a sink factory, in order to avoid mistakes of beginners.

Step 3: Mount the motherboard into case

The following will mount the motherboard to the chassis of the cabinet, for that, we only need align properly the motherboard to the holes including in the chassis, and then fix it with the screws that come standard with the cabinet.

We must ensure that the various connectors are properly located, in order to subsequently be able to mount the plates necessary for our computer.

Step 4: Install RAM modules

RAM modules can be mounted before or after placing the motherboard in the chassis of the cabinet. That depends on the decision of each.

Once we identify the banks for RAM, we must carefully place each module on them and push it slowly and without exerting force until we hear a click.

How to build a PC

That sound will let us know that RAM is installed correctly.

Step 5: Attach cables

Before continuing to introduce components, it is advisable to connect some cables to the motherboard. In principle we must connect the motherboard to the power supply.

It is also convenient connect the cables on the front panel of the cabinet, both the power and reset buttons, as LEDs, USB and other ports. To do this it is best to resort to the motherboard manual, which states clearly how they should be connected according to the motherboard model.

Step 6: Expansion cards installation

If we have decided to include some extra PC board, as it can be a video card, a Wi-Fi or Ethernet, this is the precise moment to mount.

How to build a PC

To do this we must identify the PCI-E, PCI or AGP slots in which the card must be mounted. It is placed so that the pins match with the connector, and then we pressed without force until hear the click that indicates that has been fixed in place.

Step 7: Install devices

The following will connect the devices, and first will be the hard disk. This should be placed on the support having the chassis, and once properly secured with the appropriate screws, initiate the connection.

Notably, all storage devices have two connections, one to the motherboard and the other to the power supply. We must then connect the power cord from the power supply to the hard disk slot, and then connect the cable SATA drive to the motherboard.

Basically, in the case of the optical means we should perform the same steps.

Step 8: Before closing, sort all the cables

Patience, already almost done. Before closing the cabinet, we must fix and accommodate cables that may have become loose. To do nothing better than use elastic bands or seals, which besides good aesthetics, will provide good security to internal components.

We take a last look and a final check to verify that all cables and connections are properly adjusted, and we can put the cabinet tops.

Step 9: The decisive moment

It only remains now connect peripherals to the CPU, i.e. the monitor, keyboard and mouse, as well as the cable for electrical power.

If all goes well, and the team on, just subtract configure the computer and begin installing the operating system that we have chosen.
