It usually retails for around $80 USD, offering great value for the money.

Processor (CPU)

The processor is the “brain” of your computer and is an essential part of any gaming PC. Your choice of CPU will largely depend on how powerful you want your system to be, but for a budget-friendly build we recommend going with something like the AMD Ryzen 5 2600. This processor offers excellent performance for the price and is capable of handling most modern PC games with ease. The AMD Ryzen 5 2600 usually retails for around $90 USD.

Graphics Card (GPU)

The graphics card is an important part of any gaming computer as it’s responsible for generating the visuals you see on screen.

This card is also relatively affordable and will give your system a good boost in image quality and performance. It usually retails for around $200 USD, offering great value for the money when compared to higher-end graphics cards. This card is capable of delivering smooth performance in most modern video games, making it a great choice for those looking to build a budget-friendly gaming rig.


Random Access Memory (RAM) is important for multitasking, as it allows the processor to quickly access data while running multiple programs at once. For a budget gaming build, we recommend getting at least 8GB of DDR4 RAM. This will ensure that your system can handle modern games without any issues.


Having enough storage is important for any gaming PC build, as it allows you to store all your media files and game data in one place. For a budget-friendly build, we recommend getting either a 240GB SSD or a 1TB HDD depending on how much space you need. SSDs are faster and more reliable, while HDDs offer more storage capacity for the price.

Power Supply (PSU)

The power supply is an important component of any gaming PC as it provides the power to all your components. We recommend getting a 500W or 600W power supply depending on how powerful your components are. It’s important to get a reliable and efficient power supply as it’ll ensure that your system runs smoothly without any issues.

One popular and affordable power supply for PC builds is the EVGA SuperNOVA G3 650W. This fully modular 80 Plus Gold certified power supply provides reliable power delivery and up to 93% efficiency in typical applications, making it an ideal choice for budget gaming builds.

Putting the PC Together 

Assembling your gaming PC requires putting all of its individual components together into one cohesive system. This includes installing the motherboard into its case, attaching any necessary cables or connectors, adding RAM modules as well as other expansion cards such as graphics cards or sound cards if needed. It’s important to make sure each component is securely fastened in place before powering up your PC for the first time so that nothing gets damaged during operation.

Once all of your hardware has been assembled, it’s time to install an operating system (OS). The OS provides basic functionality such as allowing you access different programs on your computer and connecting with peripherals like printers or mice via USB ports. Popular choices include Windows 10 Home Edition (for gamers) or Ubuntu (for general purposes).
