Components for Building a PC

Building a PC by yourself is fun when you know every part of the PC. It can help you better as you can make a better computer by choosing the right components for it. I’m a big fan of building my computer systems. I find it a lot of fun and you end up with a better machine when you assemble it yourself. You can also save a bunch of money. If you want to start building your computer, the first thing you need to do is acquire the parts. In this guide by Gaming Silk We will walk you through what components you need for a primary computer and offer a few suggestions for each category. 

Five Major PC Components

  • Motherboard

  The motherboard is the most integral component of a PC. It holds together many of the crucial elements of a computer, including the central processing unit (CPU), memory and connectors for input and output devices.

 The motherboard connects directly or indirectly to every part of the computer. The processor, main memory, and expansion cards are connected to the motherboard. The central processing unit (CPU) is located in a protective socket on the motherboard and links to the Northbridge.

The Northbridge chip communicates with high-speed devices in a computer, such as CPUs and RAM. For example, the Northbridge communicates with the CPU via a front-side bus (FSB). The FSB provides high-speed communication between the CPU and RAM. Still, it is much slower than the communication between the CPU and its cache.

The Southbridge connects to slower peripheral buses such as PCI or ISA. While these buses were once separate, they have been moved onto a single chip on modern systems, making it an I/O controller hub (ICH). The Southbridge also contains other subsystems such as USB ports, serial ports, IDE channels and audio hardware.

  • Processor 

The processor (CPU) is the second most integral PC component. It is the brain of your system which processes all the instructions. A CPU performs basic arithmetic, logic, controlling and input/output (I/O) operations specified by the instructions in a program.

The processor plays a vital role in determining your system’s performance and speed. And it also plays a crucial role in deciding how much heat you will generate because as the processor increases its clock speed, more power is consumed, generating more heat. There are two major players in the processor market: Intel and AMD.

  • RAM

Memory (RAM) is the third most integral component of a PC. RAM is what allows you to run multiple applications simultaneously. Larger RAM means that more applications can run simultaneously. For example, if you have 1GB RAM and you run Firefox and Microsoft Word, and then the RAM will be shared by these two programs so that they will run slower. If you have 2GB RAM or more, then Firefox and Microsoft Word will be able to use all the memory they need, which means they will load faster and work faster.

RAM is measured in GB (gigabytes). You should be ok with 4GB of RAM right now, but when Windows 8 and DirectX 11 games come out later this year, you may need 8GB or 16GB of RAM. So if you buy a computer now with 4GB of RAM that has an extra slot for another stick of memory, it will be easy and cheap to upgrade in the future.

  • Storage

Computer Storage is the fourth most integral component of a PC. It can be HDD or SSD.


  It is a storage device in which data is stored on a rotating disk, which uses magnetic heads to read-write the data. It is the oldest way of storing data, and hence it is the cheapest one. The HDD capacity ranges from 80GB – to 2TB.


It is a storage device storing data on an array of flash memory chips using semiconductor technology. They are comparatively more expensive than HDD, but they don’t have any moving parts. Hence, they are much more reliable, with less chance of failure, and are much faster than HDD. These days SSDs can be found in laptops, and even laptops with 256GB – 512GB variants are readily available. 

  • Power Supply Unit

Power Supply Unit (PSU) is the fifth most integral component of a PC, right after the Processor, Motherboard, RAM and Hard disk. The power supply unit supplies power to all the details of your computer. It is like a base that powers all the components and makes sure they work correctly.

Different power supply units provide different amounts of power to your computer. They also differ in their efficiency factor, which means they don’t waste more than that much electricity as heat energy.
