What Order To Buy Pc Parts?

Building a PC from scratch can be an exciting and rewarding experience, but choosing the right components and assembling them in the correct order can be daunting for beginners. Knowing which parts to buy first can save time and money, as well as ensure compatibility between components. In this article, we’ll guide you through the process of selecting and ordering PC components to help you build your dream computer.

When it comes to purchasing PC components, it’s important to start with the basics. This includes selecting a processor, motherboard, graphics card, power supply unit (PSU), and memory. These components form the foundation of your system and are necessary for the computer to function properly. Once the core components are chosen, you can start adding peripherals such as a hard drive, solid-state drive, case, and cooling system to meet your needs and preferences. By following a logical order of purchase, you can build a customized PC that meets your needs and budget.

What Order to Buy PC Parts?

When building a PC, it is important to consider the order in which you buy your parts to ensure compatibility and efficiency. Here are some points to consider when deciding the order in which to buy PC parts:

1. Determine the purpose of your PC: Before buying anything, you need to determine what your PC will be used for, whether it’s for gaming, video editing, or basic productivity.

2. Choose a processor/CPU: The processor is the heart of your computer, and you should choose one that is compatible with the motherboard you plan to use.

3. Choose a compatible motherboard: The motherboard is the foundation of your PC and should be compatible with the processor you choose.

4. Select the right RAM: The amount and speed of RAM you require will depend on your intended use.

5. Choose a power supply: The power supply should be sized appropriately to provide enough power for your components.

6. Select graphics card/ GPU: If you will be playing demanding games or working with graphic design, you may need a dedicated GPU.

7. Choose a storage solution: You will need some type of storage to install your operating system and save files, and you may want to consider getting backing storage options.

8. Purchase peripherals: This includes a monitor, keyboard, mouse, and speakers as necessary.

It is generally recommended to buy parts in the order listed above to ensure compatibility and to avoid purchasing something that may not work with another component. Additionally, it may be more cost-effective to purchase parts over time to spread out costs rather than buying everything at once.


1. What are the essential parts I need to purchase for a PC build?
Answer: The essential components required for a PC build include a CPU, a motherboard, RAM, a power supply unit (PSU), a storage device such as a solid-state drive (SSD) or a hard disk drive (HDD), and a graphics card (GPU) (if you intend to use the PC for gaming or graphics-intensive applications).

2. What factors should I consider when selecting a CPU?
Answer: When selecting a CPU, consider factors such as the number of cores, clock speed, cache size, and power consumption. Additionally, ensure that the CPU socket is compatible with the motherboard you have selected.

3. What should I look for when choosing a motherboard?
Answer: When choosing a motherboard, consider factors such as the form factor, the chipset, the number and type of expansion slots, the number of RAM slots, the number of USB ports, and the onboard audio and video capabilities.

4. What kind of PSU do I need for my PC build?
Answer: The PSU wattage required for a PC build depends on factors such as the number and type of components, the CPU and GPU power requirements, and intended usage. A PSU with a wattage of at least 500 watts is generally recommended for most builds.

5. What are the benefits of choosing an SSD over an HDD for storage?
Answer: SSDs offer faster read/write speeds, consume less power, and are less prone to mechanical failure than HDDs. Additionally, they tend to be smaller and lighter, making them ideal for portable builds or smaller form factor PCs.


In summary, determining the proper order to purchase PC parts requires a bit of planning and research. By first defining your needs and budget, creating a list of necessary parts, and prioritizing based on compatibility and performance, you can ensure a seamless and enjoyable building experience. Remember to consider factors such as warranties and customer support when making your final purchases. With proper preparation, you can create a powerful and reliable computer that meets all of your needs.
