More often than not, people who want to build their first gaming computer don’t want to invest more than $500. In this post, you will find a balanced PC for casual gamers for around $400.

This post is also motivated by the many requests I received to design a cheaper version of the $500 Console Killer gaming computer. So, here’s my attempt at designing the cheapest gaming PC while keeping two premises: it has to be easily upgradeable and it must include an SSD, which will dramatically boost the overall computer value.

If you see errors, misleading information, or you just don’t agree with me I would really appreciate your comments so we all can improve this post together. Try to be nice to each other and be collaborative.

Ryzen Version For This Budget?

Before you ask for it, I’ve been thinking about adding a Ryzen version of the $400 build lately. Here are my conclusions:

The cheapest Ryzen CPU is the Ryzen 3 1200, which is 20-40 dollars more expensive than the used in this build and it’s also the direct competition of the i3-7100. Adding the remaining parts would increase the budget close to the $500, so we can discard this option.

If you want a Ryzen-based build, I’d recommend you to take a look at the $500 Ryzen build here.

I’ve also been thinking about designing a gaming PC with a more powerful CPU but without a GPU, for those who want to buy later or don’t need it right now. This can be done with the 2nd generation of Ryzen processors, but still, their integrated GPU is less powerful than the one used here.

I wouldn’t recommend going that way for a simple reason: getting a better CPU also implies getting a better PSU, a better case, a better CPU fan, or even buying more RAM for when you get the GPU.

And that my friends, would be the same as buying the $800 build without the GPU.

That being said, I guess we can’t get anything better with this tight budget… at least until the new generation of GPU’s and CPU’s are released.

Best Budget Gaming PC Build Under $400

I’m really excited to introduce you this build because it’s just the best gaming PC you will find around within the $400 range. I’ve been studying what other “expert” websites recommending gaming computers under 400 dollars and I can tell you that the build you will find here in this post beats them all.

'SD STARTER 400 IA'

Intel Pentium Gold G5400 Radeon RX 550 2GB
4 GB RAM DDR4 SSD 120 GB
uATX 178 W
  1. Cooler Master MasterBox Lite 3.1

  2. Gigabyte B360M DS3H

  3. Intel Pentium Gold G5400

  4. Ballistix Sport LT 4 GB DDR4-2666 CL16

  5. ASUS RX 550 2GB

  6. ADATA SU800 3D-Nand 128GB

  7. EVGA 500 W1

Why am I so sure about that? I’m using an Intel CPU + Radeon GPU, while others usually use a crappy AMD CPU. It is really hard to fit this combination of CPU + GPU in such a low budget. And this is only possible thanks to the new Intel Coffe Lake processors.

Using an Intel processor is always a better choice for gaming computers, as they are known to have a better performance per core, which is what we are interested in to get the most out of the latest games.

As of today, Intel beats AMD and Nvidia USUALLY beats AMD, at least in the gaming industry.

In this case though, a GTX 1050 and a Radeon 550 2GB are pretty much the same in terms of performance, and lately, due to the graphics cards stock shortage that is heavily affecting Nvidia prices, the Radeon is definitely the best option.

Now you know what to look out for when deciding on one or another build you may see on the internet.

Before digging into the details, here are the goals and main characteristics of this build:

  • It allows you to play up to non-so-demanding AAA Games at 1080p + High settings + 30 to 40 FPS. This category includes games like Rise of the Tomb Raider, Doom, Overwatch or Fallout 4 among others.
  • And of course, you will also be able to play at Ultra / +60 FPS on games like LoL, Dota 2 (or any other MOBA game), Counter Strike, Paladins, War Thunders, FIFA 17 and any Indie game with low graphics requirements.
  • If you want to upgrade your computer to play ANY current game at 1080p with Ultra settings, all you have to do is to buy a better GPU, like the GTX 1060. With this upgrade, your computer would be as powerful as the $600 gaming build. The point here is that this computer is really easy to upgrade.
  • Unlike any other builds you can find around, this one includes an SSD. And this really makes a difference no matter the CPU or GPU you are using.

IMPORTANT NOTE

This build has been designed to cost EXACTLY $400, with a margin error of 5 dollars. I want to note here that it is highly recommended to get 8GB of RAM, instead of 4GB.

Why am I not including it by default? Adding the extra RAM would exceed the estimated budget of this build.

The good thing about getting just one single 4GB RAM module is that you can get another one later to take advantage of the Dual Channel. So I leave this decision entirely up to you.

Case – Cooler Master MasterBox Lite 3.1

The Cooler Master MasterBox Lite 3.1 is a micro ATX case with one USB 3.0 and one USB 2.0 in the front bay. It allows up to 3 cabinet fans and has enough room to install a full sized GPU (up to 380mm).

Another thing to note is that the PSU space is located at the bottom, which improves the computer cooling airflow, lowering the inside temperatures, and also you will get a cleaner interior.

It supports up to 3 120mm fans and also supports liquid cooling systems for the CPU.

It includes dust filters installed on the front and bottom that prevent dust from entering.

Check the Cases Guide to see other models within the same price range.

Motherboard – Gigabyte B360M DS3H

For builds mounting 8th Intel generation (Coffee Lake), the Gigabyte B360M DS3H provides all you need.

This micro ATX board comes with all the features needed for either entry-level or high-end builds for an unbeatable price and the reliability of a big company as Gigabyte!

The main features of this motherboard are:

  • Intel Optane Memory
  • DDR4 2666 RAM support
  • Tested with the major RAM brands to ensure maximum compatibility
  • Supports RGB light strips, which can be customized using the included the RGB Fusion software

It also includes a pretty handy feature called Dual BIOS: the motherboard has two BIOS, main and backup, protecting users from BIOS failure due to virus, hardware malfunction, improper OC settings or power failure during the update process.

And, of course, it also has latest-generation ports for all your needs: 4x USB 3.1 ports and 1x M.2 port to plug in a super fast SSD.

Check the Motherboards Guide to see other models with the same chipset.

Processor – Intel Pentium Gold G5400

And here is the KEY piece of the build, one of the new Intel’s Coffe Lake processors, the Intel Pentium Gold G5400.

But, why is this piece that important?

This processor is as powerful as the older Intel i3-7100 but there is a price gap between them of 30 dollars, which means we are getting an i3-7100 but 33% cheaper. Isn’t that awesome?

This also means that this build can be easily upgraded with better components in the future while reusing the same CPU and motherboard.

As for the technical specifications, the G5400 has 2 cores (4 threads) at 3.7 GHz and the integrated GPU HD Graphics 630.

The processor comes with a basic CPU cooler with pre-applied thermal paste.

Check the Processors Guide to see other models within the same price range.

Graphics Card – ASUS RX 550 2GB

Here is the ASUS RX 550 2GB with 2GB of GDDR5 memory, a base clock of 1100 MHz and 1183 MHz in OC mode.

Thanks to this little GPU, you will be able to play most of the current games at 1080p at 30 FPS, which is something pretty awesome given its price.

There’s no big difference Compared to the Nvidia GTX 1050, they both perform very similarly in most of the games.

The main difference is their prices, which have diverged a lot during the past 6 months: the cheapest GTX 1050 you can find these days will be around the $170, while you can get an RX 550 for as low as $100.

You can find a video where these two GPUs are compared in several games here.

With this GPU you can play all the current games at 1080p, low to medium-high graphics settings and stable 30 – 45 FPS and even it could hit 60 FPS on some games like FIFA’s, Borderlands’, CoD’s and others.

It also supports DirectX 12 and it is Vulkan ready, two 2016 new technologies that will be used shortly in new games.

Check the Graphics Card Guide to see other models within the same price range.

RAM – Ballistix Sport LT 4 GB DDR4-2666

As for the RAM, it is always a good idea to choose modules of the same frequency and, preferably, in groups of two. That is, if you want to install 16GB of RAM, instead of buying a single 16GB module, try to find a 2x 8GB pack.

When building super tight budget PC builds, I think the most intelligent decision is starting with one single module of 4GB DDR4 2666Mhz.

That way, you will be able to keep the build quality standards as high as possible. Nevertheless, I strongly recommend you to get another 4GB DDR4 2666Mhz RAM module as soon as you can.

I chose a 2666Mhz memory because it is the new standard frequency supported by the new chipsets introduced by the AMD’s Ryzen and Intel’s Coffee Lake’s processors, so you will exploiting its full potential.

Why shouldn’t I use one single RAM module? Learn all about choosing the best modules in the RAM Guide.

Storage Unit – ADATA SU800 3D-Nand 128GB

As I said earlier, this build features a 128GB SSD, the ADATA SU800 3D-Nand 128GB specifically.

This model was released in 2016 and it has proved over and over to be one of the best SSD available, with +1000 5-star reviews on Amazon.

It is fast (520 Mb/s write speed) and pretty durable and the selling price is pretty much unbeatable for what it offers.

Do you want to learn more about SSDs and the different options currently available in the market? Read the SSDs Guide.

Power Supply – EVGA 500 W1

It is hard to find a model that meets the quality standards while keeping a low budget but the 80 PLUS “White” Certified EVGA 500 W1 clearly nails it.

This is without a doubt the best PSU in the market to be used in tight budget gaming computers.

The EVGA 500 W1 features a quiet and auto-regulable fan which makes it pretty silent, which is something rare to find in this price range.

Other than that, it also has heavy-duty protections (that you won’t definitely find in any other PSU for this price) including UVP (Under Voltage Protection), OPP (Over Power Protection), and SCP (Short Circuit Protection).

Why are PSUs so important in every computer? Find it out in the Power Supplies Guide.

Alternative Parts

Sometimes, you will find that some of the build’s components are not available because there is no available stock or the product is no longer available. Here you will find some alternatives for those components that are likely to vary both in price and availability.

Peripherals and Extras

If you are building a gaming computer from scratch you will probably need a monitor, a keyboard, a mouse, extra storage or even a Windows 10 copy.

'Extras & Peripherals - 1080p 60 Hz'

1080p 75Hz Monitor Non-mechanical Keyboard
USB Wifi Adapter 1TB 7200 rpm HDD
  • For the Win10 license, I recommend you getting it from Kinguin instead ($25) –> link

Even though we are in 2017, every time someone asks me for a 1080p gaming monitor I recommend the Asus VG245H, released in August 2016. This is just the best 1080p monitor of the moment. Period. It features a TN panel with just 1ms of input lag, FreeSync compatible and a refresh rate of 75 Hz. You can read a mini review here:  Asus VG245H Review – The Best 24″ FHD FreeSync Monitor Under $200.

As for the keyboard and mouse, if you have a tight budget I would recommend you the Coller Master Devastator II combo bundle. For just 30 bucks you get a decent quality keyboard and mouse. The best way to check if a product worth the money is checking the customer reviews and this product is a true winner. It has 4 out of 5 stars and +300 customer reviews. You won’t find anything better for this price.

If you want to forget about running short of free space then you should consider the option of getting a standard HDD just to store static data like images, music, torrent downloads, games, etc. Just remember to keep the operating system installed on the SSD to get the fastest performance levels.

How To Build a Computer

There are tons of tutorials and video tutorials out there about how to put together the different PC parts.

The Newegg guys did a great job with a series of video tutorials which I highly recommend.It's an easy process if you follow the process step by step and you will feel like a god when you see that you build your Gaming PC from scratch!

If you have never built a computer before don't worry, I know the idea of putting together all the parts and dealing with all the cables can be overwhelming.

That's OK. If I can do it you can as well.

What would I recommend you is to have a quick look at the following video so you can get an idea of what's this about.

And if you have any questions feel free to comment at the end of this post :)!

Things To Note

  • Nomenclature: the configurations are named according to the used CPU and GPU:
    • IN: Intel CPU, Nvidia GPU
    • AA: AMD CPU, AMD GPU
    • IA: Intel CPU, AMD GPU
    • OC: the configuration is designed for Overclocking.
  • Internal storage: the best option here is to add an SSD exclusively for the Operating System. This will increase the general performance a lot. A second standard HDD can be used to store games and general data.
  • Power supply: the chosen power supplies will give you more than enough room to satisfy the computer needs. The Intel CPU . Nvidia GPU have lower consumption rates. For example, an i3-8350K with a GTX 1060 will consume up to 300W, which is really low. In those cases, the recommended PSU capacity is 450W, so it works under optimal conditions.
  • Component brands: you can be sure that the brands used are first brands only, just the best of the best. There are maybe some of them that don't sound familiar to you but they are still top brands in their respective business sector.
  • You don't need to buy all the build components at the same time: unlike consoles, you can buy the build's components as you could afford them and once you have all the parts start to build it. You can even buy all the parts except the GPU (if you bought an Intel CPU, which includes a basic integrated GPU) and add the dedicated graphics card a couple of months later.

I've been always an avid gamer with limited resources. This led me to learn how to build the best gaming computers within tight budgets. Now, I want to share the knowledge I've acquired over the years with the world!

    1. Hi Hondo,

      Short answer: no.

      Long answer: I only include the main build parts’ price to calculate the final build price because. It’s upon each person to decide whether they need to buy a Windows OS, use they current produce license, or if they want to install Linux (which is free), or maybe another OS.

      So, due to that variety of options, this is something that I can’t take into account when calculating the price of the computer builds. I hope it makes sense to you.

      Thanks for your interest and if you have any further question just raise your hand,
      Adrian

        1. Yes of course, and you could also have both installed in two separate partitions of the same hard drive.

          If you are planning to use Windows in the near future, you can grab an official free copy and buy the license whenever you are ready. Link: https://www.microsoft.com/es-es/software-download/windows10

          Just keep in mind that in order to install both Linux and Windows, you will need to install Windows first.

          Here are some guides you may find useful:
          * How to install Linux: https://www.cnet.com/how-to/how-to-install-linux/
          * Dual boot: http://www.howtogeek.com/214571/how-to-dual-boot-linux-on-your-pc/

          Hope this helps 🙂

  1. I think 4GB of Ram is way to low for any PC build let alone a gaming one. Windows 10 will use almost 4GB by itself. I realize you were trying to fit a tight budget but, 8GB is the absolute lowest for any gaming PC.

    1. Yeah, you are totally right. I will add a note above the build’s detail to warn about this. It’s really difficult to replace any of the current parts without breaking the build balance.

      Thank you so much for the heads up!

    1. This case supports up to 315 mm GPUs and up to 155mm CPU coolers.

      So yes, the Corsair SPEC-ALPHA is a great choice, especially if you want to upgrade the main components of this build in the future.

    1. Yes, you can! In fact, up until recently, the recommended PSU for this build was the EVGA 430 W1 (instead of the 500 W1).

      The thing is that the 500W version is cheaper than the 430W.

      In any case, for a build like this, 400W should be perfectly fine 🙂

    1. I wouldn’t go for anything beyond the GTX 1060 3GB. This also includes the 1050 Ti.

      The CPU (Intel G4650) would bottleneck a 1060 6GB, so unless you are also willing to upgrade the CPU, I’d simply go for one of the mentioned above.

    1. Correct, most of the parts come with their own required cables, so don’t worry about that
