Best $400 Gaming PC Build, Ultimate Budget Build

Looking for the best $400 gaming PC of 2019? Well, you’ve come to the right place, not only are we going to help to show you how to build a fantastic PC on a tight budget, but we’re also going to provide you with support along the way!

If you have any questions during this process, feel free to leave a comment below, and I promise to get back to you as soon as I can!

If you’re interested in seeing other price points of pc builds, check out our overall listing of PC builds here.

We Also have an even more in depth article discussing PC builds ranging from $200-600, and we included a unique upgrade path that isn’t normally discussed. See our new article about our cheap gaming PC’s here.


$400 might not seem like a lot, but you’d be surprised as to how good of a PC you can get. This PC build isn’t able to run new games on ultra settings, but it can handle breakout titles like Fortnite or Apex Legends without breaking a sweat.

Thankfully we’re out of the cryptocurrency craze of 2018 allowing us to build a PC that would’ve cost upwards of $500 plus for under $400!

With this build, you should expect to play most newer titles on medium settings. This includes graphically demanding AAA gaming titles such as The Witcher 3 or Sekiro Legends Die Twice. As I said earlier this game mops the floor with battle royales and other graphically demanding games like Minecraft. You should expect medium to high quality while getting a consistent 60FPS when playing these types of games.

If you like playing the latest games on ultra settings check out my other builds that are more expensive as that is not what this build is for. I’d recommend you get the $600 build if possible. It’s only a few hundred dollars more, but it makes a HUGE difference.

With that being said, with this $400 build, you’re still getting something that’s more powerful than most consoles and can play any new game out there in 2019.

All right no time to wait around! Let’s get into the $400 ultimate budget build that’s going to dominate 2019!

Build Breakdown

The Thermaltake Versa H15 Mini-Tower Case is a well-built case for a solid price. Many cheaper cases have a mediocre look to them, but the Versa H15 looks like a gaming computer that is worth another $30 on top of its actual price! Not only does it look nice, but you’re also getting something that’s well-built and is designed with airflow in mind.

This deal is also sweetened with Thermaltake’s 3-year warranty which protects you from any potential risk. Honestly, the Versa H15 is a no-brainer for people on a tight budget and that makes it a perfect candidate for this build

If you do want to find other cases, below is a link  that you can use  to find cases that will fit this build

Power Supply:

Thermaltake makes some of the most affordable, yet high-quality power supplies for computers, so it’s no surprise that they’d be one of my top choices. I chose the 500 Watts Thermaltake power supply for this build and It should power everything just fine. Even with its low price the case remains highly efficient maintaining 80% efficiency. Thermaltake also gives you a 3-year warranty with the purchase of this power supply

The Thermaltake 500 watts power supply isn’t anything special, but for those on a budget, this is something that I’d consider to be one of your top choices as it offers insane value for the price and is an essential edition to this $400 gaming PC build.

Video Card:

Yep, this is the star of the build and the reason why this build can still play on such good settings even though, it is so cheap. The GTX 1030 is an awesome little graphics card that to me personally is the best entry level 1080p graphics card on the market at the moment. This little card can be used to play most modern games on high settings at 1080p making it an awesome card to have. If you are not gaming at 1080p then this thing will perform even better, but I would still recommend 1080p if you have a monitor capable of it.


While the Ryzen 1200 is a quad-core processor, It beats out anything that intel has in the same budget range and is quite honestly the best budget CPU that’s on the market right now. It’s part of AMD’s new ryzen generation series and man does it impress. While processors are very important when it comes to gaming, the main thing we want is a processor that won’t bottleneck the CPU and I can safely say that the G4400 is more than powerful enough for the GTX 1050.


The Asus 320M-K motherboard of this build is an awesome micro-ATX board that is very affordable but still gets the job done. The motherboard complements the processor very well and there are no compatibility issues. For AMD, it’s the best budget motherboard on the market at the moment and if you ask me it easily competes with motherboards at a higher price-range.


Entering 2019, 8GB’s of RAM is absolutely essential. That’s why even though we’re on a tight budget, I had to make sure to include this. I could cheap out and go for 4GB’s of RAM, but that would be a major mistake! RAM stands for random access memory and it’s what your PC uses to keep tasks running quickly. The more RAM the more demanding things you can run. Most games use around 3-4 GB’s of RAM nowadays.  No matter how good your PC is if it runs out of RAM it’ll lag out on you. The RAM I chose was Patriot’s 2x 4GB option. It’s not the best RAM in the world, but it gets the job done at an affordable price

Hard Drive:

Western Digital is easily one of my favorite hard drive makers. They provide some of the best prices to value hard drives that you can find that are also extremely reliable. This $400 gaming PC build features WD’s 1TB hard drive. This hard drive will provide enough space to play many games and should last you for a long time. If not, Western Digital offers a 2-year limited warranty that you can work with.

If you wanted to save, you could go down to a 500GB hard drive in the beginning and then get another hard drive when you have more money in the future. I recommend just getting the 1TB hard drive though.

Why’d I Exclude Optical (CD) Drive: 

I excluded the optical drive because there is no real need for one anymore. I really can’t remember the last time I used mine and it is definitely not essential to building a gaming PC any longer.  This build is already very tight so in order to get more performance, I decided that an optical drive just wasn’t worth it. I understand that some people might still want the Optical Drive, so I have linked a good one below that also comes at a great price point.

If you did want an optical drive here’s one below that I found that was cheap yet very high quality.

View Latest Price

You can’t use that new PC of yours to its full potential if you don’t have a few peripherals(accessories). Here are a few peripherals that I would recommend you getting. Keeping in mind that this is a budget build I’m going to try to keep this cost low, but just like getting a TV with a console and a good stereo you still need to pay a significant amount to get these. The good thing is once you do get these, they will last you for a good deal of time before you need to upgrade.

Recommended Monitor: Acer SB220Q IPS Ultra-Thin

Acer SB220Q IPS Ultra-Thin Zero Frame Monitor
  • 21. 5 inches Full HD (1920 x 1080) widescreen IPS display
  • And Radeon free Sync technology. No compatibility for VESA Mount

This is the best 1080p budget monitor out there. Made by Acer, A very reputable company, this monitor is 21.5 inches in length and weighs about 4 pounds. For the price, you really can’t go wrong due to amazing color contrasts amazing brightness and the matte display. If you are looking to get a 1080p monitor on a budget this is the one to get.

Recommended Keyboard/Mouse – Redragon S101 Gaming Keyboard Mouse Combo

Redragon S101 Combo
  • PC GAMING KEYBOARD AND GAMING MOUSE COMBO: Includes Redragon RGB Backlit Computer Gaming...
  • RGB BACKLIT GAMING KEYBOARD; 7 different RGB Lighting modes & effects, 4 backlight brightness...

The Redragon S101 Combo is probably the best budget keyboard and mouse you are going to find. One thing Redragon knows how to do is make combo’s, and when you are getting an LED set that actually feels better than some $80 combo sets that I’ve used, then that says something. The keys feel very responsive and feel as though you are using a high-tier gaming keyboard. The mouse has different levels of DPI(How sensitive a mouse is) making this very customizable. I 100% recommend this combo set if you are on a budget.

Recommended Headset: HyperX Cloud Stinger Gaming Headset

HyperX Cloud Stinger
  • Lightweight headset with 90 degree rotating ear cups
  • 50 millimeter directional drivers for audio precision

First of all, this is a really stylish headset. The Mpow EG3’s Gaming Headset is definitely eye candy, but what’s most important in a gaming headset is the sound quality and the mic. The sound quality of this headset is loud and very clear which provides an overall dynamic experience. The Mic is also good and clear with low static. Overall this headset is good, but what really sets it apart is its very low price. If you are looking for a nice stylish budget headset then this is it.

Recommended Wifi: Netgear NightHawk AC 1900

For those of you who aren’t going to be using an ethernet cable and are looking for an affordable wifi adapter. I’d recommend the Netgear NightHawk wireless USB adapter. For the price it’s a really good deal considering that adapters that only provide much slower speeds cost more than the NightHawk adapter. It’s reliable and will allow you to connect to the internet and play games (specifically online ones) with zero to no connection based lag.

Operating System Options

Ok, Now it’s time to talk about Operating Systems. So what are operating systems? Operating systems are basically software’s that manage computer hardware and also provide different services. There are many operating systems, but the biggest ones available to you are Windows and Ubuntu(Linux). These are both good choices but for the most people Linux will not be sufficient as it is an Open source program and Windows will be the choice for you. Since most of you are new to PC building, I will briefly go through each program and why you should or shouldn’t go with them.

Ubuntu (Linux)


Linux is free and if you are on a budget then, this might be what you want to go with. The one problem with Linux has been that it is not widely supported by game makers at the moment (although this is changing quickly due to steam releasing an OS based on Linux!). It is also very technical and can easily become overwhelming if you allow it to.


Windows 10 Logo

Windows is a familiar program that everyone knows and chances are you’ve already used it before. This is probably the go to bet for most people. The main reason to get this OS is because of all games being made for windows, but with popularity comes problems in the form of viruses and trojans that you need to pay attention too.

Windows 7, 8 or 10? 

I would recommend getting windows 10. not only does Windows 10 offer many gaming improvements over its predecessors, but it’s also the best looking OS out of the bunch in my opinion. Support for the older versions also decreases as the world begins to move to newer operating systems.


Windows 10 USB Version

  • Produce 3D objects easily
  • Improved gaming capabilities
  • Comprehensive systems protections

Windows 10 Disc Version

  • New and improved start menu
  • Downloadable apps that work across platforms

  1. Hi i have this exact same build and I seem to have fps drops in games like League of Legends and even Counter strike. should I replace my g4400 and get an I3-7100? and Rainbow six:siege has terrible audio stutters and micro stutters it isn’t even playable.

    • Michael, there are so many parts to consider for this, if you are running a 1080p monitor, and you have a decent graphics card – your CPU will likely be the bottleneck. What you probably want to do is install MSI Afterburner to see what usage your CPU and GPU are using, and you will be able to tell where your main bottleneck is to upgrade.

  2. Hello, i,m thinking about using this build, but my problem is that i already have an amd monitor, and the gpu here is nvidia, so the freesync of the monitor isn,t compatible with the nvidia gpu, can you recomend me an amd gpu in the same range of the nvidia monitor listed here? Thanks!

    • Answering that question is like answering “How long is a piece of string?”. For general computing, this computer will last you for ages, for gaming – this is still a very respectable build and can produce good resolution & fps, which should be able to handle games in the future without problem. You get what you pay for typically, so if you’re able to save a few more dollars check out our slightly more expensive builds

  3. Hi! I’m considering trying this build. I just want know will it run all\most current mmos (BDO, Blade & Soul, Divinity 2, Dragon’s Dogma Online, the upcoming Dauntless etc)? Mmos will be my focus.


    • Hey Keith,

      Everything in this build should be able to handle most MMO’s easily, but I would recommend potentially looking into upgrading to the G4600 CPU. It’s about $30 more, but as MMO’s are more CPU heavy, I’d say it’s a worthy investment.

      Let me know if you have any questions.

  4. Hey there, I have just found the world of computers and was wondering if this build can support 1080p video editing and content creation really well?

    • Hey Jake, this build should hold its own, but I’d recommend checking getting a G4600 instead of the G4400 to better handle the 1080p video editing! Let me know if you have any more questions!

  5. Hi Frank will this build be able to run modern games, GTA, Fallout, Prey that kind of stuff at 1080p and 60 fps? I don’t need high settings

      • Good thing for gamers on a budget is that entry graphics cards and CPUs are getting better and better. This combo will handle any game out there at an affordable price.

        • Hey Frank just some quick questions
          1: Can I make a boot drive of Windows from my Windows 10 laptop?
          2: What does the GB mean after the graphics card name (1060 w/ 6gb vs 2gb)
          3: Can this computer run 1440p games at a passable framerate?
          4: Is 1440p even worth it? I try to find stuff online but I can’t see any noticeable difference?
          5: Can the CPU run a game and Youtube video at the same time?
          6: How quiet will this build be?
          Thank you so much for your help

          • Hey Abe,

            1. Yes, you can!
            2. Contrary to popular belief, graphics cards do use memory as well! They need dedicated memory for graphics rendering that’s faster than RAM. in simple terms more memory just means that it can better process games.
            3. I wouldn’t get this build for 1440p at all. I’d recommend getting a $600+ build for anything decent at that resolution.
            4. If you’re on a 1080p monitor then you’re not going to see any difference, but I believe it’s worth it!
            5. Yes!
            6. This build should be pretty quiet as long as you don’t overload it.

            If you have any more questions, let me know!

    • Hey Berto,

      This build will be able to run modern games with a mix of medium and high settings and achieve between 50+ fps. If you really want that smooth 60 this should be able to handle all the games above at 60+ FPS.

  6. Hi Frank,
    i was thinking about buying my younger brother a gaming PC for Christmas but I don’t want to spend TOO much money aha. he likes games like Overwatch and CSGO. would you recommend this PC for games like these?

    • Hey Jessie,

      This gaming PC build would be perfect for someone who likes games such as CSGO and Overwatch but’s on a budget. Luckily both games are very polished, and he could easily run them on max settings at a pretty good framerate on 1080p settings.

  7. Would this be a good build for $400? A friend of mine has this build wants to sell it to me for $400, is it worth it?
    CPU: AMD Phenom X4
    Motherboard: ASUS Sabertooth 990FX R2.0
    8 GB of DDR3 1866 mHz RAM
    500 Watt PSU
    120 GB SSD
    nVidia GTX 550ti
    Windows 10
    NZXT S340 Razer Edition Mid-Tower Case

    • While that build has a nice case, everything else about it is completely inferior to this build. Especially the graphics card and CPU. The RX 460 destroys the 550 ti in terms of performance and the AMD Phenom X4 is nowhere near the i3-6100 either. If you’re going to be spending $400 I recommend you get this build as it’s superior to your friends PC in every way. A few years ago this might’ve been a good deal, but now? This build is probably worth less than $250.

        • Yah, but even with the windows this PC build just isn’t worth it. It’s severely weaker than this build for the exact same price. He’d one hundred percent regret buying his friends PC if he plans on doing any real gaming.

  8. As a begginer in the sort of stuff could I please get why it has no cooler refered? If its for a motive like its an obvious choise or something, could i please get a recommendation?

    • Hey Filipe,

      This build comes with stock coolers that should be more than enough for this build. You could always get an aftermarket cooler if you want in the future.
