Computer Components List

Every PC is made of the same basic hardware.  Each item listed below has a brief explanation, of what the component is and what it does for you.


The Processor or CPU is the “brain” of your computer, it performs the tasks requested by the operating system and the software. The faster the  processor, the faster it performs the tasks.

One thing to note though is that most people will not use the full speed of a high performance CPU, even if your a hardcore gamer the GPU (graphics card) is the far more important component to get the performance you want.

Unless you are after the a cheaper & less powerful CPU will probably be fine, so don’t waste your cash. Get the CPU for the tasks you need today and always remember that as you building your own, you can always upgrade components later.



The motherboard is the base of you’re entire PC. It connects all the components together.  It has all the core items needed to run the computer such as the expansion slots (PCI, PCIe), connectors for the monitor, speakers, network and USB ports.

They do come in different sizes or “form factors”, so it determines the size of you computer/computer case.  The mid-range size is typically the best option.  Most people who opt for the larger towers are for expansion bays to house additional hard drives & DVD drives.

Many modern motherboards have onboard video and sound.  If you want higher performing video and sound keep in mind how many and type of expansion slots you need.

If you know you definitly want your own video card then opt for a mainboard without on board video.

That is where does it need to fit and most importantly its dust protection and noise.

What generates the most noise are the fans which keep the computer cool and to a lesser extent the hard drives.  Noise is an important factor.  A noisy computer humming away can slowly drive you crazy! Select a computer case which highlights “quiet” as a feature.

Additionally if you are adding extra fans ensure that they have noise dampening as a feature. Also consider buying SSD hard drives over traditional SATA as they perform faster and without noise.



Corsiare RAM memory moduleRAM or more commonly known as “Memory” stands for Random Access Memory. It’s kind of like your short term memory.  It stores temporary information your computer needs to make programs run faster and stores data such as open documents etc whilst you have them open.

If you need to run alot of programs at once or have high storage needs for large data files (documents, spreadsheets, presentations etc) then the more memory you have the faster everything runs.

The size of RAM required is a moving target, however it is the cheapest and fastest way to upgrade your computer if you find it running slowly.  This is a sliding scale however there will come a point where more memory will not necessarily mean better performance.

If you run virtual machines for developing, testing or just playing with other operating systems such as linux then you will need more RAM to accommodate this.

As a rule of thumb requirement 8GB of RAM is required to run Windows 10 along with your normal applications, remember this is a moving target and your mileage may differ.

Graphics Card

Graphics Card or GPUThe Graphics card, also known as a video card but more accurately the GPU is a processor which is specifically made to handle graphics.  This is what you plug your screen into and draws all the information you see on the monitor.

For those purposes you will definitely need a dedicated graphics card. The prices and needs of graphics cards differ greatly but don’t spend more than for what you need right now as fast as they may be it will be outdated within months.

Sata Hard Drive

Example of a physical SATA Hard Drive


Hard drives come in many different sizes and speeds. The type of hard drive will be determined by how much data you have to store and speed.

Hard drive speed can be a factor, this is by no means a be-all and end-all but there are basically two types. SATA which has physical platters to store the data and spin around with a needle which reads and writes the information, then there is SSD (solid state drive) these produce no noise and are significantly faster.

Optical Drive

The Optical Drive

The optical drive or known more widely as a CD, or DVD/Bluray drive.  With so much available for download and the use of USB sticks/drives not everyone needs an optical drive these days.  However one is  recommended if you are building a HTPC (Home Theater PC).

As these are typically quite cheap, about $20 depending then its not an expensive addition to your computer. You may also which to burn DVDs or Blu-Rays for data/movies or permanent backups for example, these are more expensive though.


Power Supply

The Power Supply (PSU)The power supply unit (PSU), is possibly the least exciting but most important part of your computer. It directs electricity to the components in your PC.

The considerations here are the demands and number of components in your machine – the higher performing graphics cards, number and type of hard drives and the CPU the higher wattage power supply is required.  The power supply should be the last component you shop for once you’ve chosen all the other parts.
