Gaming Performance

A 300 dollars with cheap PC build can give you smooth gameplay of games in low-intensity settings and at 50+ FPS. Sure, you won’t be able to play video games under ultra-HD or 4K settings, but that’s totally fine for casual gamers like you.

What Games You Can Play

For a $300 PC build, you can expect to play games that are within 60FPS. Our build can allow you to play most competitive title games, but if you are looking forward to playing PUBG, then you should consider getting a $500+ build.

300 dollar PCs are great options for those who love playing low-intensity games such as League of Legends, DOTA 2, Counter-Strike: Global Offensive, and more. But, to get you more games to play, getting a dedicated GPU and upgrading to a better processing power should be your go-to goal.

Accelerated Processing Unit

An Accelerated Processing Unit (APU) works just the same as a CPU, but the only difference is that APU comes to its built-in graphics. APU is powered by Vega Graphics, a more robust yet also more affordable option as compared to Intel CPUs.

On the other hand, APU’s graphics will entirely depend on the RAM. If you want to get more out of the APU, increasing your RAM is the best way to go.

If you need a comparison in mind, the 3200G APU that comes with Vega 8 Graphics can work as seamlessly as the NVIDIA GEFORCE GT1030. For a much lower price, choosing APUs can be an excellent decision for building your 300 dollar gaming PC.

For processing power, we don’t just want the best CPU under 300 dollars. Rather, we want an APU. The AMD Ryzen 3 3200G is always ready with its cutting-edge Vega 8 graphics.

The best advantage of purchasing this motherboard is it can house any AM4 CPU you wish to purchase from the market.

Best RAM: Patriot Viper Steel Series DDR4 8GB

Gaming PC Under $300 Top 6

When you get an integrated graphics card, you should know that such a GPU doesn’t come in with their VRAM. They will take off your computer system’s RAM that can make your computer’s performance slower. Your main goal should be not to reduce your computer’s RAM at all costs, just to save up from not buying a VRAM.

We found these Patriot Viper RAM sticks that are made for budget builds to help you have cost-efficient gameplay every single time. We considered that our 300 dollar PC build doesn’t come with a dedicated graphics card since we are on a tight budget, so dual VRAM sticks are the best way to boost your 300 dollar computer’s performance.

The Patriot Viper Steel DDR4 8GB RAM sticks come with 3000MHz to 4400MHz RAM, which suits our $300 budget for an excellent performance. The 8GB RAM just has excellent specifications for low profile gaming; then you can push forward into getting a 16GB RAM or higher in the future.

Best SSD storage: Crucial BX500

Gaming PC Under $300 Top 7

We want to get the best performance from our prebuilt gaming PC under 300 dollars even with a limited budget, so we decided to choose an SSD rather than the traditional HDD for this build. Using an SSD is much faster, and it also helps your computer boot up within seconds.

The Crucial BX500 is relatively a little expensive for this build since it is an SSD, but you can always opt for an HDD if you are really on a tight budget. Yes, HDD’s are indeed cheaper, the prices between SSD and HDD are of a far range from each other, but performance-wise, you get the best value when choosing an SSD.

We might only be getting a 240GB SSD over choosing a 1TB HDD, but we want to stick with faster boot and responsiveness that an SSD has to offer. It is also worth knowing that the Crucial BX500 is 300% much faster than a regular hard drive, so what’s not to love?

  • Improved overall responsiveness
  • High energy efficiency
  • Micron 3D NAND
  • Limited 3-year warranty

Bonus: EVGA 100-BR-0450-K1 450 BR Bronze

Gaming PC Under $300 Top 8

A power supply unit in a computer has a crucial part in efficiency and long-term use. The top recommendation that we can give you is not to settle on power supplies with unknown or generic brands just because you want to keep your budget tight. Settling over to cheap brands may not be a great investment since they might wear off quickly after just months of using it.

The worst part is that it may even damage other computer components. It is always safe to pick a branded PSU with a rating of 80+, just like the EVGA 450 BR that we chose. It comes with an 85% higher efficiency rate under high or regular workloads. So far, it is one of the best brands for PSUs that avid and frugal gamers can always pick.

This EVGA BR 450 is also equipped with a quiet fan, which the manufacturer states to run for a longer lifespan. The easy and on-the-go installation of this power supply is also impeccable since you can simply plug and play, wherever you go.

  • Heavy-duty protection
  • Quiet cooling fan
  • 3-year warranty

These components are hand-picked and well researched to help you find the right product for your $300 budget without compromising the performance.

Let’s go over the other considerations that you might have to think about before buying the best CPU for gaming 2021. These categories will help you further understand the importance of picking the correct hardware before building your custom gaming pc.

Budget

Budget is one of the first areas to consider before building your custom gaming PC under $300. If you’re planning to splurge on triple title A title games, with 100fps, then $300 is barely enough to get you this gaming PC. But, there are so many other games you can play even on a tight budget, including some of the most popular MMORPG games of today.

What’s important in having your budget is that you would exactly know which hardware will be best to pair up with other hardware in terms of specifications and affordability. Since our focus is to build a $300 gaming PC, then you cannot expect high-end gaming unless you upgrade.

Having a budget ahead of time helps you understand the limitations that you have before purchasing hardware. All of the products that we have listed above came from Amazon, and you should know that the prices might fluctuate from time to time. You might want to check sale dates to get more discounts for your PC build.

Besides, you still need to account for other stuff like the best $300 gaming monitor, gaming peripherals like mice, keyboards, headsets, and so on, and you also need to spend money on the games itself.

Building Ease

If you’re having your first PC building, it might seem a little challenging to build your own rig. Take time to research different cases, and choose something that will help you have a smoother installation process. Also, make sure that the case can accommodate all your components as you install them inside.

Alternatively, you can simply opt for a prebuilt gaming PC, like the HP Pavilion Desktop Computer.

Performance

Even with a limited budget of $300, you can still very much build a good quality PC. In fact, most gamers usually build a computer that can work well for gaming and working too. The good news is that we have created the exact computer for $300 perfect for gaming, as well as any simple everyday tasks.

From tons of tabs and Microsoft Office tasks, our gaming PC build under 300 dollars is quite impressive, all thanks to its multi-core features. The cores help run programs and processes simultaneously without lagging.

Overclocking

In gaming, we would want our PC to feel snappier than usual, right? That’s when overclocking comes in. The hardware’s quality is becoming more and more extensive which makes overclocking much easier for computers now.

To give you a better idea, overclocking can give your computer a better and faster application processing without paying more for the performance. You just have to be careful because one motherboard flared up when we tried overclocking it, so make sure to don’t overdo it.

For our $300 PC build, one thing to note is that you’ll likely only get light overclocking, but even so, you won’t really need much overclocking for AMD Ryzen chips, since they are extremely efficient when it comes to performance.

Upgradability

Upgradability is also another important factor to account for when you’re building your gaming PC. In reality, gamers don’t really stick to one hardware, they would always aim for better upgrades. Plus, your components will not last forever too.

Before building your gaming rig, make that your machine is always ready for upgrades. Don’t get too excited when upgrading too, you have to minimize the number of components that need upgrading, so you can prioritize which hardware needs the upgrade the most.

The good news is, the $300 gaming PC build that we created comes with the latest motherboard that is very open to future upgrades. And, the PC case that we have selected is also a solid choice for adding additional storage if you need it in the future.

Design

Who doesn’t want an eye-catching computer, right? While the hardware is important, you would feel more satisfied with your 300 dollar PC build when it looks sleek, aesthetic, and modern. However, aesthetics don’t come cheap- just like performance.

The Rosewill case that we have selected is pretty decent in terms of aesthetics. However, if you want to up your game, there are various cases that come in high-end designs and styles that you can choose from if you increase your spending budget to around $400 to $500.
