We’ve updated our $400 build with a fantastic AMD Ryzen APU, a processor with integrated graphics. While the new generation of Ryzen chips has been released, the older ones still offer better price to performance and make sense in a build at this price. We’ve also updated our prebuilt computer recommendations, bringing you fantastic value for those who prefer to purchase rather than build.

With the 400 dollar gaming PC our main focus was to give excellent value for money whilst still providing a decent level of gaming performance. While we aren’t at the price range where value is at its absolute best, we have enough wiggle room in the budget to make 1080p gaming quite playable. While this may not be our cheapest gaming PC build, it’s still extremely affordable with a slightly stronger processor and graphical power.

We consider this build as being entry-level for both performance standards and build difficulty making it the perfect gateway into PC building, so let’s dive straight in.

Before we explore the hardware specs in more detail and why we chose them, let’s take a quick look at the build as a whole and precisely what it has to offer. We’ll discuss how we managed to stick to $400, some of the compromises that came up during the hardware selection process, and how it performs on a day-to-day basis.

What Do You Get For Your $400?

One of the biggest struggles we encountered when putting this build together, was sticking to that strict price of $400. Luckily for us, AMD APUs undercut their Intel rivals.

Like many price-conscious custom builds, the aesthetics were compromised for increased performance. The case is pretty basic but still offers some RGB and a user-friendly design.

Performance

At this price range, you need to be realistic with what performance you expect to achieve. For us, we focused on designing a build that can achieve 900p-1080p gaming, that is tailored towards low-intensive games such as CS: GO, Fortnite, and Overwatch. The APU should be able to churn out 60+FPS on these games on low-medium settings.

AMD APUs

If you’re new to PC building, then you’re probably a little confused at this point, especially with all the abbreviations we’re throwing around. So, let’s discuss the most important aspect of this build, the APU.

An APU, in layman’s terms, is a CPU and a GPU rolled into one. Yes, that’s the reason why this build doesn’t have a graphics card. Over the years, integrated graphics have become increasingly powerful. The VEGA 11 graphics that the 3400G comes equipped with has performance that lies somewhere between the GTX 1030 and the GTX 1050.

The great thing about these APUs is that you can upgrade to a more powerful standalone GPU down the line, and still have a powerful multi-core processor at your disposal. It truly is the best of both worlds.

How We Choose

Our team has years of experience behind them building PCs for a range of needs and budgetary requirements. All this knowledge combined with hours of research, user feedback, and onsite benchmarking is what goes into choosing the best components for our builds.

We look for value for money, how the components perform together, and focus on gamer’s needs to make sure our builds are the best bang for your buck.

We build all these PCs ourselves, in-house, so trust us when we say we want to make them as good as possible. We actually use all these builds ourselves day-to-day in the WePC offices.

How We Test

We build each of our selected PC’s from scratch to make sure all the parts we recommend work well together, fit into the selected case, and provide the best performance possible for the price range.

Once built, the PC’s are used in the office for everyday work as well as a range of games from light to heavy-duty. While we test, we also run benchmarking tests to see how well our builds perform, all while keeping an eye on the temperature of the components themselves.

We tested our AMD builds against their Intel counterparts and found that these CPU’s performed better across the board, and for a lower price. This is why we only recommend an AMD version.

NOTE: Due to the ongoing effects of the global coronavirus pandemic, some retailers are experiencing stock issues. WePC constantly updates our pages to reflect current availability, so if the PC or part you want shows as out of stock, check back later or check out these alternatives.

Prebuilt Gaming PC Under $400

It is always a great idea to build your own desktop computer, especially if you’re restricted on how much you can spend.

Nonetheless, not everyone is fond of building their own gaming computer due to the hassle that comes with it. If you’re one of the folks that aren’t overly keen on the idea of building your own, then you’ll be happy to know we’ve searched the web for the best prebuilt gaming PC for around $400.

In the Q1 of 2019, the shortage of GPU greatly affected custom-built prices, so we added these sections to our builds. This was what triggered the why you should buy a prebuilt PC now trend. While this advice was mostly only relevant for a short window in time, there are still great prebuilt gaming desktops in the $400 range:

Enough of the preamble– let’s break down each individual component in this system and why it was chosen over the other options out there.

Our best custom-built gaming PC for under $400 is an excellent example of good gaming performance when sticking to this price. Whilst the components that go into the design of this PC are considered low-end, they still provide some of the best price/performance in today’s market. With AMD’s flagship APU at its core, you’ll be able to take on low-intensive games such as; CS:GO, LOL, DOTA2, and Rocket League.

while keeping the price relatively low, we can sill squeeze in the 5600G, a 4core/ 4thread CPU with Vega 8 graphics, and a base clock speed of 3.6GHz, with a max boost of 4GHz. The 3200G provides enough power to play low-intensive games such as CS: GO, Fortnite, DOTA 2, and Rocket League at 1080p while maintaining smooth, playable FPS.

The motherboard is an area we can save some money on for this price range, and that’s why we’ve opted for the B450M. This board offers enough in terms of features and is compatible with Ryzen CPUs. That being said, it’s still effectively an entry-level board but slots nicely into this $400 build. Ultimately, if you’re looking for an affordable board that’s going to achieve everything you’d want from a gaming motherboard, then look no further.

Patriot is a trusted and reliable brand that brings some of the most affordable hardware offerings to our shelves. For that reason, we’ve gone for 8GB of their DDR4 Viper Series 3000MHz RAM kit in our $400 build. With this RAM, you’ll be able to push pretty much any game you want without trouble. That being said, your CPU will feel the effects long before your RAM does, so you are still limited to what the 5600G can do. On the plus side, the RAM is quick enough to extract excellent performance out of the CPU but you should opt for 16GB when you begin upgrading this machine.

You’ll be glad to hear that this build makes use of a super-fast SSD storage solution. If you aren’t familiar with SSDs and how they work, in basic terms, the technology inside an SSD differs dramatically from that of traditional HDDs. This means they can read/write data much, much faster. We’ve gone for Teamgroup’s 240GB SSD in this build as we think that’s enough to get you up and running. You might need to expand your storage capacity down the road to keep up with demand, but for a start, this is a great SSD to go with.

Of all the entry-level cases we’ve recommended here on WePC, this is definitely the most aesthetically pleasing. It also has great out-of-the-box cooling, a clean design, great airflow, and plenty of room for a GPU or a few extra hard drives down the line. The Zalman T7 currently showcases superb value for money and is the perfect option for this $400 gaming build. This PC case comes with two 120mm fans, providing your system with some airflow out of the box.

When buying a cost-effective PSU, we always recommend buying from reputable, reliable manufacturers. If you don’t, you run a serious risk of hardware malfunction down the line. For that reason, we’ve gone for a Gigabyte 450W bronze-rated PSU. It isn’t going to win any awards for the most outstanding PSU, but it certainly does the job and will provide efficiency and safety while you use it.
