Introduction into Building Your first PC

How to build a Computer

Introduction into PC building.

With most Prebuilt Computers being expensive and not suitable for the tasks we want to carry out, there has never been a better time to build your own PC. At first this may sound like a daunting task but once you understand your requirements and what Components you will need to achieve this it can be quite fun, therapeutic even.

What do you want to build?

When building your first PC it easy to get lost and overwhelmed by all the options out there after-all, with all the different components available today there is probably an almost infinite amount of different combinations you could build. So before you get started it is important to understand the requirements of your PC based on what it will be used for is it just a simple office PC in that case it wouldn't need as much processing power as a Gaming PC.

What PC components do I need?


A Motherboard is usually the first component you will pick for your new PC, this component will decide the form factor and size of your PC, this is important as not all components will be compatible with your chosen motherboard, for example the motherboard will affect which processor you can use, the memory technology, so whether your board supports (DDR2,DDR3,DDR4 etc) and the amount of extra slots you have which will affect the amount of additional modules which can be installed.

(CPU) Processor/central processing Unit

The CPU is the brains of the computer this will contribute to overall performance of your PC. When picking a CPU pay attention to the gigahertz (GHz) as the higher this value is the faster your processor will be, but it will consume more Power and usually will generate more heat leading to higher system temperatures so you would need to make sure that you have suitable airflow and cooling for your PC.

(RAM) Random Access Memory

(RAM) is usually one of the cheaper ways to increase your PC Performance because it gives your PC more Random Access Memory which means the more GB RAM you have installed the more available space your PC has to temporarily store data. RAM is used in pretty much every aspect of the PC, examples of when this is used are ; Multiple tabs open in a browser, multiple programs running at the same time, background apps and services that may be running and even for moving your mouse.

When selecting RAM to install into your PC, It needs to be compatible with your motherboard to see if it is compatible you would need to check the physical form of the module usually for PCs it is UDIMMs then you would need to check the memory technology that is supported, this would be DDR4, DDR3 etc.

There’s an easy way to find compatible upgrades: Download the Crucial® System Scanner and let it do the work for you. It displays how much memory you currently have, the maximum memory capacity of your computer, and available upgrades for your specific system.


There are two main storage types, these are (HDD) hard disk drives and (SSD) Solid state drives, hard drives usually give you more storage space but SSDs are more commonly used now due to be 6x faster on average and up to 90x more energy-efficient  than hard disc drives.

Speed of storage devices is measured using read and write speeds this is how fast data is loaded up (read) and how quickly data is saved (write)

(PSU) Power supply unit

The Power supply unit is the unit that will supply power to your whole PC, when selecting a PSU you should pay attention to the amount of power it supplies you will see 100w,750w etc its important that there is enough power to power all PC components.


When it comes to cooling, you want to keep your PC as cool as possible as if your system overheats this could potentially destroy your system. Components that are used for cooling are fans and liquid coolers, You will also need to make sure that your cooling components are able to fit within your PC case/housing.
