If you’ve been beating yourself up about doing nothing productive during quarantine, don’t. Sometimes nothing is exactly what you need. Other times, it’s nice to make something with your own hands. That’s what this guide is about. How to build a PC from scratch.
It can be daunting for a lot of reasons—it’s expensive, it’s complex, it can get messy. But I want to be clear: if you can build an Ikea table, bookshelf, bed, or anything that comes in more than one of those deceivingly heavy flatpacks, you can build a PC.
What Do You Need?
No matter what your experience level is, you should use PCPartPicker. Not only does it have everything you’ll need to buy, but it lets you build your PC piece by piece right there on the website, making sure all your hardware will play nicely together. They even have a few example builds you can tweak to your liking if you want.
Regardless of what kind of PC you’re building (home office or gaming), the components you need are going to be the same. You’ll need a motherboard, a CPU, storage, memory, a power supply, a case, and a monitor. The only thing you might not need if you’re mostly using this PC for home office tasks is a GPU, but it’s necessary for photo or video editing and gaming. That’s a lot of stuff. Here’s a little breakdown of what each component does, and some hardware recommendations.
Every other component plugs into this circuit board. It’s the highway they use to communicate and collaborate. They come in different sizes and configurations, and each one looks a little different, but they all fill the same function.
This is the brain of your computer. It sockets directly into the motherboard, and it’s the single most important component of your PC. But that doesn’t mean it has to be the most expensive. We’ll get to that later. If the CPU doesn’t mention including thermal paste, make sure to get some too. This one will do.
If you’re planning on playing games on this PC, you’ll need a graphics processing unit, or GPU (also called a graphics card). This is a specialized processor that’s designed and optimized for handling primarily visual data like the graphics in games. It’s also used in video and photo editing, and other graphics-intensive tasks.
- MSI GeForce GTX 1660: This one is a good pick for gaming on a budget.
- MSI Radeon RX 570: The RX 570 is getting a little long in the tooth but it’s a great buy for AMD fans.
- MSI GeForce RTX 2060: If you’re looking to get into high-end gaming, this card strikes a good balance between power and price.
This is your PC’s walk-in closet. This is where you store all your files, your games, your movies, your documents, your photos, your everything. You can always add more storage later if you need it.
You’ll see a lot of the same terms when you’re looking at memory and storage, but they’re very different. Memory is more like that one table you toss things on to deal with later. It’s scratch paper; it’s short term. It’s very important though because software uses memory to cache (temporarily store) data in a place it can be retrieved very quickly.
Your power supply is a little box that keeps the electricity running to each and every component. It determines how quick and powerful your PC can be. The faster it is, the more power it needs, and you always want to have a little more than you need, just in case.
Your case is just what it sounds like. It’s a metal box. It might be covered in glass panels and etched aluminum but inside, it’s just a big metal box that holds everything together.
- Corsair Obsidian Series ATX Full Tower: There are lots of different kinds of cases out there, some are super small, others are enormous. And your decision will ultimately come down to the design you like as much as anything else. If you’re unsure what to get, this one from Corsair is great for your first build. Other case manufacturers we like are NZXT, Fractal, Phanteks, Cooler Master, and Lian Li.
Putting it All Together
We’re not going too into the weeds here because the internals of every PC are a little different, but in general, here’s how you should go about putting all these components together.
