Launch PC BuilderWelcome to the exciting world of PC building! Creating your own computer might seem daunting at first, but it's a rewarding experience that offers several advantages over buying a pre-built system. You get complete control over the components, often better value for your money, and the satisfaction of creating something uniquely yours.
This guide is designed for beginners and will walk you through the essential steps, from planning your build to selecting components. By the end, you'll have a better understanding of the entire process.
Building a PC requires patience and attention to detail. Take your time with research and assembly. If you're ever unsure, our compatibility checker can help you avoid costly mistakes.
Before you even think about specific parts, the most crucial first step is figuring out what you will use the PC for and how much you're willing to spend. These two factors will heavily influence every component choice you make.
High performance for modern titles
For video editing & design work
Once you know the purpose, set a realistic budget. PC build costs can range from a few hundred dollars for basic systems to several thousand for high-end gaming or workstation rigs.
*Percentages vary based on use case. For content creation, CPU and RAM typically get a larger allocation.
Now that you have a purpose and budget, let's introduce the main parts of a computer and what they do. We'll dive deeper into selecting each one in later steps.
The "brain" of your computer that processes instructions and performs calculations
Renders images and handles graphics processing, crucial for gaming and visual work
The main circuit board that connects all components together
Temporary memory that stores data your computer is actively using
Long-term data storage for your operating system, applications, and files
Converts electricity from your wall outlet to power your components
Houses and protects all your components while providing airflow
Keeps components from overheating during operation
Understanding how these components work together is key to building a well-balanced system. Each part plays a crucial role in the overall performance and reliability of your PC.
The CPU and motherboard are tightly linked, as they must be compatible in terms of socket and chipset. Start with the CPU based on your needs and then find a compatible motherboard.
The Central Processing Unit is the brain of your computer. Here's what to consider:
The motherboard connects all your components. Key considerations include:
For general use, an entry-level CPU like an Intel Core i3 or AMD Ryzen 3 may suffice. For gaming or productivity, mid- to high-end CPUs (e.g., Ryzen 5, Ryzen 7, Intel Core i5, i7) are recommended.
Always check the motherboard's CPU compatibility list on the manufacturer's website before purchasing. Some older motherboards may require a BIOS update to work with newer CPUs.
