Main PC components to build your own PC explained

A PC system is comprised of many internal parts, some necessary for basic operation, some add additional processing power for certain applications and functions such as dedicated graphics cards (GPU) to give the desired gaming performance and dedicated sound cards for the cleanest audio solution. All of these components are defined as follows:

  • Motherboard - The printed circuit board (PCB) that enables communication between all parts of the computer. It holds the CPU and RAM as well as providing connectors/slots for drives and expansion cards. This also where the chipset is housed, which controls the CPU and determines how many and what features the motherboard has, such as overclocking ability and the number of Sata connections.
  • Processor (CPU) - Runs the programs and is essentially the brain of the computer. Everything you do on your computer is a set of instructions that pass through the CPU. A CPU with more cores or a higher clock speed can ‘process’ instructions faster and more of it in a second than a CPU with less cores or a lower clock speed.
  • Memory (RAM) - Every piece of data that is currently in use on your PC system, such as your operating system files, an open game, antivirus background processes, a spreadsheet or word document that you are working on is stored here for fast access to and from your CPU (processor as explained above). The more RAM your system has, the more data can be open at once without slow downs or ‘hanging’ (when your PC freezes for a few seconds).
  • Graphics card (GPU) - The GPU is the most important component for running games smoothly; especially the more graphically demanding ones. 3D and virtual reality games require a ton of mathematical calculations that determine what should be displayed and where at a given point in a 3D scene. Thinking about how many images are drawn in a second to display a game, you can quickly imagine the amount of graphics processing power required. This is all done through the GPU, and the better the graphics card, the more frames per second (FPS) you game will display, providing a smoother gameplay experience. Graphics cards are also used for rendering videos and processing heavy image calculations on large files in manipulation and design applications such as Adobe Premier and Photoshop.
  • Sound card - While onboard sound solutions have come a long way in the past few years like isolating the the part of the PCB that processes audio from the rest of the motherboard to remove interference, they still have a long way to go before they are on par with a dedicated option which usually uses higher quality and specialist components to better process higher fidelity audio such as a higher frequency range capability before distortion occurs, a dedicated amplifier, and expanded interface options such as full size audio jacks, analogue RCA outputs, and MIDI inputs for musical instruments.
  • Network card - A dedicated network card can expand your network connectivity options of your system. They can add wireless functionality if your motherboard (usually the higher end ones) doesn’t already support it. They can enable multiple network connections or upgrade the speed of a wired connection entirely, making them especially useful for business networks with multiple connections and heavy traffic.
  • Hard disk drive (HDD) - This is where all files, folders, applications, and all other data are permanently stored. When you start your PC, in-use operating system files are read from your hard drive or solid states drive (explained below) and stored in the RAM. The same goes for whenever you open any file, game, or application.
  • Solid state drive (SSD) - Faster than a HDD as it stores data on solid-state flash memory with no moving parts. SSDs are incredibly useful for read heavy applications such as games, your operating system, and large video or photo files. They also write faster too so when it comes to rendering a complete video project, depending on your CPU, this will also write to your drive much faster than with a standard hard drive.
  • Optical drive (ODD) - Although standard DVD readers/writers are gradually becoming more and more obsolete as online storage becomes cheaper and internet speeds get faster, there is still a wide use for Blu-Ray drives when needing to store data for long periods of time and wanting to free up space on your internal hard drives. These optical drives read and write files from/to DVD or Blu-ray disks.
  • Power supply - The PSU or Power Supply is essentially the heart of a PC system, feeding power to all other components. The required wattage of the power supply depends on the rest of your components although it always a good idea to have a PSU that has the capability to provide more power than is actually needed. This future-proofs your system for any potential upgrades you may make and contrary to a still- living misconception, doesn’t cost more to run. If anything it costs less as the PSU isn’t working as hard (closer to it’s limit) to power your system. They are available in different efficiency ratings which are categorized by Bronze, Silver, Gold, Platinum, and Titanium ratings (the lowest being bronze, getting better all the way to titanium). These ratings represent how much power is drawn from the mains and then lost through the operation of the power supply itself. Higher ratings cost less energy to run and generally have a longer lifespan. The PSU converts mains AC power to low-voltage DC power required for the components.
  • Upgrade bundles - The majority of our bundles are comprised of well-matched, tried-and-tested components consisting of a motherboard, RAM, CPU, and a CPU cooler. They are pre-configured kits, some overclocked, designed by us at Overclockers UK to help you build your PC. All you need to add is your desired storage requirements, a graphics card if needed, a PSU to power it all and a case for your system to call home.
