The Best Gaming PC Under $400 In 2023

$400 gaming pc
Quick Reminder
The total cost of our gaming builds generally doesn’t exceed the target budget. We always pay attention to the final cost and each of our builds strictly remains under a particular budget most of the time

If you want to play most of the modern titles on a Gaming PC for under $400, then you will be happy to know that it is totally possible. 400 dollars may not be enough to max out graphics but it is certainly sufficient to have good eye candy without compromising much on the performance.

We know that it is difficult to keep up with the latest PC hardware releases and researching for a good configuration can be exhausting. You don’t need to do that as we have already prepared for you the list of best PC parts for this awesome $400 gaming PC.

We keep our listed parts updated regularly to give you the best possible configuration for the money and at the same time, we try to make the build easily upgradable in the future.

Is $400 Good For A Gaming PC?

$400 is adequate for those who are looking to get decent framerates at 1080p without going too hard on the graphical settings. With this PC, you can expect decent performance on low-medium settings in most AAA titles and on up to high settings in esports games such as CSGO, Fortnite, Valorant, LOL, etc.

Fps will range from 40-70 depending on the title and the settings used but overall, it is easier to get this much performance without having major dips.

In 2023, $400 doesn’t give you a lot of options to choose from especially in the GPU category. We have limited budget CPUs and GPUs that can fit into this budget as a lot of money is invested into other PC hardware such as RAM, Motherboard, PSU, Storage, and Case. Fortunately, we have APUs as well that bring both CPU and GPU on the same chip and perform just as well as a dedicated budget GPU.

For this build, we will be looking at what we can get for this budget and what will be the best for you.

For the $400 build, it is best to spend around $100 on a CPU and up to $200 if we opt for an APU to skip on a graphics card. For $100-$200, we have some very good CPUs that feature 4-6 cores and hyperthreading as well. More cores mean faster processing and better multitasking but at the same time, the single-core performance matters a lot.
If the processor is a locked one, then it is better to go with a locked chipset motherboard as well but in the case of an overclockable processor, an unlocked chipset motherboard will help you overclock the CPU for some additional performance. Most importantly, the motherboard should have all the necessary ports and slots for installing PC components and connecting peripherals.
I recommend going with 8GB RAM at the minimum. This will eliminate all sorts of bottlenecking and will be sufficient for 1080p gaming. 16GB will be great for a no-compromise performance but that depends on the cost of the total build as we would like to not exceed our total budget by a big margin.
Graphics Card
We have very few dedicated graphics cards that cost $100 or less and can outperform some of the best APUs available today. Unless the CPU-GPU combo is cheaper and better than an APU, we would skip the GPU to avoid a cost increase.
Storage Drive
Solid State Drive is our priority. SSDs are fast and they acquire less space. They help in speeding up the boot of OS as well as games. For this $400 build, I recommend going with at least 500GB of a SATA SSD or NVME if possible.
Power Supply
Whether you build a $400 PC or a $4000 PC, a reliable power supply is a must. It should provide all the cables and connectors to power up your components and should be at least 80 Plus rated for good power efficiency. Generally, 400-500 watts of a reliable power supply will do the job just fine for our $400 build.
The selection of our case should be based on the motherboard used, pricing, features, and space clearance. It is better to go with a micro-ATX tower for budget builds if the motherboard is micro-ATX, however, if a good ATX tower costs nearly the same as a good micro-ATX case, we will go with the former.

Parts list For $400 Gaming PC

Processor and GPU

AMD Ryzen 5 5600G and Vega 7
AMD Ryzen 5 5600G and Vega 7
Cores/Threads- 6/12
Clock- 3.9/4.4GHz
TDP- 45W-65W
Overclocking- Yes

There is no better APU than the Ryzen 5600G for under $150. Being a powerful 6-core APU, it completely eliminates any need for an entry-level GPU as well. Ryzen 5600G is based on the Zen 3 architecture that is faster in IPC compared to the Zen 2-based previous-gen APUs. It features 6 cores and 12 threads clocked at 3.9/4.4GHz of base/boost frequency and supports overclocking too. This makes it an excellent choice for a budget build well as a mid or high-end gaming PC.

The iGPU on the chip is the Vega 7 which features 7 GPU cores and a core clock speed of 1900MHz. Vega 7 is generally more powerful than some of the current budget GPUs under $100 like the Nvidia GT 1030. Vega 7 can play almost any game at 1080p with low to medium settings and with constant 40+ fps. For games that are less graphical intensive or are old, medium settings should be the choice.

As the APU is also overclockable, you can increase the core clocks of both the CPU and the GPU to have a good impact on the performance. For this, I recommend using the Ryzen Master software as it helps overclock, the CPU, GPU, and RAM as well. To know exactly how much performance you are going to get in different games, watch the video below.


Corsair Vengeance LPX 8GB DDR4
Corsair Vengeance LPX 8GB DDR4
RAM size- 8GB
Type- DDR4
Clock- 3200MHz
CL Timings- 16-18-18-35

Corsair Vengeance 8GB RAM is an excellent choice for budget builds as it brings both high clock frequency and low latency for quicker operations. This RAM module comes with an 8GB capacity featuring a clocked speed of 3200MHz which is ideal for Ryzen CPUs, especially the APUs where the iGPU utilizes the main system RAM.

The tested latency of this module is 16-18-18-35 which is tighter than most budget RAM modules out there and to cool the PCB continuously, it comes with an aluminum heat spreader on the top. 8GB will be the right start for this gaming build and in the future, you can add another stick for a no-compromise workload.


Gigabyte B450M DS3H WiFi

Chipset- B450
RAM support- 64GB, 3600MHz
Storage- 4x SATA, 1x M.2
PCI-E slots- 2x PCI-E x1, 1x PCI-E x16

To overclock the Ryzen 5600G, it is important to have at least a B400 or B500 chipset motherboard. The Gigabyte B450M DS3H Wifi will not only allow you to overclock but also features an inbuilt Wifi adapter. The board is definitely cheaper than most competitors and costs nearly $80. It gives you dual DIMM slots for RAM installation and supports RAM frequencies up to 3600MHz which is definitely good enough.

There is a single PCI-E x16 slot for discrete GPU if you ever want to install one in the future and two PCI-E x1 slots for expansion cards like Wifi cards if you want to have a wireless connection. Except for these, the board is very basic and brings all the important slots/ports you will need. At the I/O, you will get a PS/2 port for older peripherals and 8x USB ports for newer ones.


Western Digital SN570 500GB
Western Digital SN570 500GB
Brand- Western Digital
Capacity- 500GB
Interface- NVME
Read/Write- 3500/3500MB/s

I always recommend going with an SSD no matter what budget you have. Using an SSD makes your PC a lot faster than using more RAM. Currently, both SATA and NVME SSDs are cheaper than ever and for this build, I chose the Western Digital P2 500GB NVME SSD that gives you 4X more read/write speed than the entry-level SATA SSDs.

It has Read/Write speeds of up to 3500/3500MBs which makes the operation blazing fast and your games will load in a couple of seconds. With 500GB of storage space, you can store your OS and games easily. However, it is recommended that you buy another 1TB SATA SSD in the future if you ever run out of space.

Power Supply

Cooler Master MWE White 450
Cooler Master MWE White 450
Wattage- 450W
Power Efficiency- 80+ White
PCI-E- 2x 6+2 Pin
Warranty- 5 years

To power everything, all we need is a decent 450 Watts of power supply from Cooler Master. The MWE 450 is an excellent choice for the price and brings flat black cables for easy cable management. It comes with dual 6+2 pin power cables that will be handy if you upgrade to a discrete GPU.

It is rated at 80 Plus which means less heat generation and more than 80% of power efficiency on typical loads. Moreover, you will get OV/UV protection features to avoid any physical damage to other PC components.


Cooler Master MasterBox Q300L
Cooler Master MasterBox Q300L
Type- Micro-ATX
Dimensions- 387 x 230 x 381mm
Weight- 3.7Kg
Material- Steel, Plastic

To host all of our components, we need at least a Micro-ATX form factor case. There aren’t enough good ones that are cheap but the MasterBox Q300L is one of the best and most affordable choices right now. I have used this case in one of my previous builds and I can say that it is really spacious.

It doesn’t feel like a Micro-ATX chassis but more like a mid-tower except that it doesn’t have a lot of expansion slots to fit a full ATX motherboard. As we are using a micro-ATX motherboard, all of our components will fit perfectly. Even if you were to add and upgrade the already used components, you would be able to do easily due to the spacious interior.

It features a fully ventilated front panel with a dust filter to allow a good amount of air without letting the dust inside. Moreover, the ventilation is extended to the top also where you can install two 120mm fans for balanced airflow. The case comes with an acrylic side panel for a clear view of the inside and is easy to handle.

The case has an adequate number of routing holes and good clearance at the back for easy cable management too. In my opinion, there isn’t any major CON except that it is lightweight and doesn’t have a tempered glass side panel for a more premium look.

Is The $400 Gaming PC Upgradeable?

Definitely. Every gaming PC we recommend is upgradeable and this $400 PC is no exception. Whether you want to change your CPU without changing your motherboard, or whether you want to add a power GPU without changing your power supply, you can do all of that. However, we always advise you to be balanced in your approach when it comes to upgrading a single or multiple parts.

The first upgrade I recommend for this build is a discrete GPU. As the system uses an APU, the most obvious and excellent upgrade will be adding a GPU that will max out graphics on any game on at least 1080p resolution. For this, I recommend going with an RX 6600 XT or an RTX 3060 at the minimum. You don’t have to worry about bottlenecking as Ryzen 5600G can support high-end GPUs more powerful than the RX 6600XT/RTX 3060 without creating the least bottleneck.

The next good upgrade will be adding another stick of 8GB RAM module that will be sufficient for any gaming or non-gaming task. You can open multiple chrome tabs and run a game at the same time and will be still left with a few gigs of memory. For storing more games, add a 1TB of SATA SSD and you are good to go. For overclocking the Ryzen 5600G APU, you can get a 120mm AIO or a dual tower Air cooler and if you want to upgrade to a 240mm or bigger AIO cooler, make sure you change your case first to a mid-tower that supports big AIO radiators.

Finally, if you are not satisfied with the overclocking result, get a better and bigger ATX B550 or X570 motherboard that will not only provide you with a strong VRM with a lot of power phases but will also bring more PCI-E lanes for maximum bandwidth distribution to the components resulting in higher speeds. Before that make sure you also upgrade your case to a mid-tower to avoid any compatibility issues.

Best PreBuilt PCs Under $400

If you are not able to build a PC by yourself or if you don’t have time to do so, then you can get a PreBuilt gaming system that will get you started right away. There are a few PreBuilt systems for around $400 that can play games decently at 1080p resolution. You can’t expect better components on PreBuilt PCs especially the Power Supply, RAM, and Motherboard. Therefore, the performance can be a little slower and on top of that upgrading can be a bit harder.

Shinobee AMD Quad Gaming Computer
Shinobee AMD Quad Gaming Computer
AMD Athlon X4 950
Radeon RX 550 4GB
16GB DDR4, 256GB SSD+500GB HDD
Wifi and Windows 11 Prof

The Shinobee Quad Gaming PC is a perfect choice and is the best Prebuilt computer for $400 as it comes with some of the latest components that are suitable for the latest games. The CPU used is the Athlon X4 950 quad-core CPU that is installed on an AM4 motherboard. It is clocked at 3.8GHz and allows overclocking as well. With an AM4 socket motherboard, it is easily upgradable to a higher-end CPU and makes this PreBuilt better than the most $400 PreBuilts out there.

You will also get a dedicated Radeon RX 550 GPU that is as good as the Vega 7 if not better in some games. It comes with 4GB of VRAM and plays almost every game with medium settings at 1080p. The main system RAM is 16GB with a 256GB SSD and 500GB hard drive that is perfect to start off and won’t require any addition very soon. All of this is hosted inside a decent micro-ATX chassis that comes with a pre-installed RED LED fan and features a transparent side panel.

Shinobee ships this PC with Wifi and Windows 11 Pro pre-installed which will save you a lot of time and on top of that, you will get 2 years of warranty on parts and labor with 24/7 support. It is definitely a great competitor to the custom $400 gaming build we recommend.

HP Elite Minitower Gaming Desktop(Renewed)
HP Elite Minitower Gaming Desktop(Renewed)
Intel Core i7 with 4 cores
Radeon RX 550 4GB
Wifi and Windows 10 Prof

This one is from HP and comes with an Intel i7 quad-core processor. The page doesn’t list what generation it is but more likely it is one of the 2nd, 3rd, or 4th gen. It features a clock speed of up to 3.8GHz and features 8 threads. This should be enough for handling any game today and combined with the RX 550, the gaming experience will be just fine at 1080p.

It comes with 16GB DDR3 RAM, 128GB SSD, and a 1TB hard drive to store a good amount of games and files. This is really impressive at this price and just like most PreBuilt PCs, you will get Wifi and Windows 10 Pro pre-installed. HP is also providing an office keyboard/mouse combo bundled for absolutely free so you can save some money for future upgrades. This is a good desktop for $400 for which I don’t have any major complaints.

Final Words

$400 isn’t sufficient for a very smooth gaming experience but with some settings compromised, 40-70 fps is definitely achievable. With the configuration we recommend, you will be loving gaming more than ever before if you are a new member of the PC Master Race.
