If you’re thinking about building your own PC, you’re probably thinking about getting the best PC components for the job. While the sheer amount of possibilities can make choosing feel a little daunting, this guide is here to assist make the process a lot easier.

Without a doubt, learning how to build a PC is not for the faint of heart. It’s a task that will put your patience and endurance to the test, and there will be times when you just want to throw in the towel, go to your local home electronics store, and buy the best computer money can buy. However, we guarantee that all of your hard work in making your own will be well worth it when you sit back and admire the end product.

There are numerous things that you will require when it comes to PC components. There’s a lot to think about, from the finest graphics card to the best motherboard and everything in between, and the things you choose will be mainly determined by the budget you’ve set aside for this project.

The good news is that we’re here to help you find incredible bargains on all of the PC components you’ll need to get the job done. Having a clear vision of what you want will greatly improve your PC-building experience. And, with this guide, we can assist you in starting your planning and research, as well as finding the best PC components at a fair price. In this manner, you can get your setup up and running without adding any additional burden.

From the finest RAM to the best hard drives and every other component you’ll need to build your dream PC, here’s our rundown of what PC components to buy and how to accomplish it all without breaking the bank.

The budget

Whatever anyone tells you, every build should begin with two key elements. A budget and a goal. The budget is obvious; how much money are you willing to spend on your new ride? And what about ambition? That is, determining exactly what you want to do with your spanking new equipment.

It may sound insane, but the economic worth of a 700-dollar system is significantly more than the value of a $4,000 monster. The lesser your budget, the more you’ll have to stretch every dollar in order to buy various PC components. Seasonal deals, on the other hand, can make budgeting easier.

We recommend that you set out to create a gaming PC with a particular aim in mind. Do you wish to buy one of the greatest gaming computers? Or would you want a home theatre PC that blends in with your living room? Do you want to edit the 4K video? To maximize savings and performance, all of these require different PC components.

Even though most PCs should be able to handle almost any task, it’s wiser to concentrate on the PC components you truly require. Because you don’t want to be a jack of all trades and a master of none when it comes to the best PCs.

Process this

We don’t call the CPU a central-processing unit for nothing; it’s the most important component of any PC, which is why we’re starting here. Choosing the finest CPU begins with deciding between AMD and Intel, the two dominant chipmakers in this category.

Then it’s an issue of selecting the best part for your budget. AMD Athlon processors, as well as Intel Pentium and Celeron processors, are inexpensive and well-suited for basic computing chores, media playing, and simple lifestyle applications. Meanwhile, Intel Core and AMD Ryzen cater to the broadest range of users wishing to create anything from a low-cost HTPC to a high-end gaming PC. Finally, on the high end, there are the Intel Core X and AMD Ryzen Threadripper for greater performance.

Intel Core i5 processors have long been the standard for gaming PCs. This is because most mainstream games (with the exception of the occasional strategy title) are more graphically intensive than CPU intensive, thus you don’t require the most powerful hardware. However, this has been steadily improving in recent years, with titles such as Battlefield V taking advantage of the multithreaded speed of higher-end processors. Still, you should be alright in most games with something like the Intel Core i5-9400, as it will keep up.

The mother of all boards

A good CPU is useless without a good motherboard. Depending on the chip you select, you’ll be locked into a set of mobos with a variety of different chipsets. But the first thing we’ll answer for you is what size motherboard is best for you.

ATX, E-ATX, and XL-ATX boards are designed for large storage solutions and powerful graphics card configurations. If you want a smaller system, Micro-ATX or Mini-ITX are your best bet, offering a more compact size at the expense of fewer slots for graphics cards and other PCIe add-in devices.

Your processor selection will also decide which motherboard will function with your system. This includes ensuring that the CPU sockets are properly aligned as well as having the appropriate chipset. For example, Intel Coffee Lake and Kaby Lake CPUs use the same LGA1151 socket, however, the former requires a 300-series chipset, and the latter was released with a 200-series chipset. Similarly, Ryzen and Ryzen 2nd Generation share the same AM4 socket, but the most recent AMD CPUs gain the most from the new X470 platform.

Depending on the size of your chassis and whether or not you’ve chosen an Intel processor, the ASRock Fatal1ty Z370 Gaming K6 (for ATX), Asus Z370-G (for Micro-ATX), or Asus ROG Strix Z370-I Gaming (Mini-ITX) all suit the bill.

Graphics cards

Graphics cards, the final component of every PC build’s essential components, define what your desktop will be able to visually present. While PCs with integrated graphics may handle simple tasks and even 4K streaming, building your own media and gaming box necessitates the separate graphical power that only a dedicated GPU can provide.

If you only want to play games at 1080p, consider the Nvidia GeForce GTX 1660 Ti or the Nvidia GeForce GTX 1660. Either of these GPUs is a good “bang for your money” option, with 60fps in most AAA games at 1080p. These cards should last you at least the next two years.


What exactly is RAM? RAM (random-access memory) is the lifeblood of any PC, and you’ll need plenty of it to keep things working smoothly. RAM, like short-term memory, stores bursts of information for a limited time in order to accomplish tasks rapidly, therefore all of your data will pass through this component of your PC.

With this in mind, when it comes to performance, we’ve always preferred capacity over speed. After all, nothing says ‘killer rig’ like having 38 Google Chrome Tabs open at the same time, along with Discord and a game of your choosing.

The Corsair Vengeance LED, HyperX Fury, and G.Skill Rampage V are all excellent memory kits that combine cost, speed, and durability. 16GB (2x8GB) of dual-channel DDR4 operating at 3200 MHz is great for gaming at 1080p right now and should last at least the next 3 to 4 years.


If RAM is your computer’s short-term memory, storage is its long-term memory. This is where you keep all of your data, whether it’s a document, a photo, a movie, game saves, programs, or even the operating system.

Similarly, storage exists in a variety of forms and rates. Hard drives are wonderful for storing a large amount of data at a reasonable cost. Meanwhile, the finest SSDs can be significantly faster, but enormous capacity come at a high cost.

Thankfully, SATA SSDs have grown so commonplace that the average Joe can now find drives with one or more terabytes of capacity for less than the price of a considerably slower hard disc. They’re all you need for a snappy system, and the Samsung 860 Evo comes highly recommended. Install your operating system and a few games, and watch your load times and overall user experience improvements.

NVMe SSDs are also popular because they may provide five-to-six times quicker data transfer speeds, and there are currently some cheap choices available. The Adata XPG SX8200 is a remarkably low-cost and fast drive. If you want to get right to the good stuff, the Samsung 970 Evo is the way to go.

If you have the opportunity, we recommend picking up a 1TB old school HDD for additional zoom. Western Digital’s Blue drives are usually a good place to start, and you can get them for a good price most of the time.

Power supply

Investing in the greatest PC power supply is the most important part of your PC setup because it provides electricity to all of the other components in your computer. Without this critical foundation, your PC will not even boot, and a system constructed on weak foundations would also fail.

In practise, you’re unlikely to need more than 650W for a single GPU design like the one we advocate here. When searching for a power supply, it’s best to pick one with 20% more capacity than you’ll need: 10% for overclocking and another 10% to ensure you’re not always taxing your PSU. The greater the efficiency rating (from good to best; bronze, silver, gold, platinum, etc.), the more efficient the system.

If you’re not sure how much power you’ll need, go to PCPartPicker(opens in new tab), enter your specifications, then check the top of the page to see how many watts the system will need from the wall.

Don’t cut corners here. When a cheap power supply fails, it might take your entire system with it.

CPU coolers

To cool either the Ryzen or the Intel processor of your choice, you’ll need one of the best CPU coolers. CPU coolers are classified into two types: air-coolers and liquid-coolers.

Air coolers, as the name suggests, use air to push heat through a network of heat pipes and fins known as a heatsink. These CPU coolers are normally inexpensive and simple to install, but they can occasionally interfere with the installation of RAM with tall heat spreaders or big graphics cards.

Liquid-coolers, on the other hand, are more sophisticated since they require a closed loop of coolant to keep CPUs cold. These are frequently more efficient than air coolers and can keep your CPU running at lower temperatures. The only disadvantage is that these liquid-cooling units can be more expensive and difficult to install at first.

There are a few passive coolers that are nothing more than smartly constructed heatsinks, thanks to technological improvements and an obsessive pursuit of dead silence.

Regardless matter the sort of CPU cooler you purchase, make certain that it is compatible with your system. If you select Intel, you’ll need the LGA 1151 socket, which supports most common Core processors. If you’re going with AMD, you should seek for the AM4 socket.
