What Order Should I Buy My PC Parts?

When building a PC, it is important to carefully consider the order in which you purchase your parts. This can help ensure that you have all the necessary components and that they are compatible with each other. The ideal order for buying PC parts is as follows:

1. Set a budget and make a list of components you need. This list should include your desired CPU, motherboard, graphics card, RAM, storage, power supply, and case.

2. Start with the CPU and motherboard. These are the foundation of your PC and will determine the compatibility of other components.

3. Choose the graphics card. This will depend on your intended usage, such as gaming or video editing.

4. Select the RAM and storage. RAM amount should match your CPU & Motherboard. For the storage you should consider both an SSD and a HDD.

5. Lastly, choose a case that fits your components and provides adequate cooling. Check if the case you want can accommodate the motherboard as it can come in different sizes.

Important notes:

– Make sure all components are compatible with each other and fit within your budget.
– Do some research first on the components you want, always check the expected power draw to make sure that your power supply is sufficient.
– Prices fluctuate, so check online or in-store regularly to find the best deals. Sometimes it’s worth waiting for a sale.
– You can always wait to purchase a component, for example, if you have a weaker graphics card, one can always wait and save up until you can afford an upgrade.
