Best $400 Gaming PC Build, Ultimate Budget Build

In Budget Gaming PC Builds, PC Gaming Builds by FrankLast Modified: / 20 Comments

If you are looking for the best $400 dollar gaming PC build, you have come to the right place. You will learn how to build an awesome PC while remaining under your budget. Well without further ado lets dive in.


$400 dollars might not seem like a lot, especially due to you needing to get so many different components to build a PC and yes, this isn’t going to be able to run any new games on ultra, but that doesn’t mean you can’t make a decent PC on this budget, especially since as 2016 ushers in, parts begin to drop in price making a computer that would’ve been $500+ a few months ago around $400.

With this build, you will be able to play most games on ultra settings and get over 30 frames per second, but you will probably struggle with new graphically demanding titles on the market such as Fallout 4 or The Witcher 3 to which you will most likely be on high to medium settings.

I would recommend this build for someone who wants to get into PC gaming, but isn’t very serious about it and mostly plays indie titles or less graphically demanding games such as Skyrim, or MMO’s.

If you like playing the latest and the greatest games on ultra settings check out my other builds that are more expensive as that is not what this build is for.

  • Screwdriver
  • (Optional) Static Wrist Band
  • Some Guidance…

I’ve never used a static wrist band and as long as you don’t build your PC on a carpet or touch a metal surface before you gaming you should be just fine.

Here is a video that you can use as a reference when putting this gaming PC together. It’s very easy to follow and Concise.

If you have any further questions about building a PC, that this video did not answer, feel free to leave a comment below and I will answer it promptly.

Build Breakdown


71omKMyMvNL._SL1000_The Cooler Master Elite 342 Mini Tower Case is pretty awesome value. Yes, you lose some beauty, but the case is small and easily houses everything in this build.  The Case can be changed as it is entirely up to you whether or not you like the design, but if you change the case don’t forget that this comes bundled with a 400W power supply that you will need to get. Other than that this case gets the job done and provides some awesome value that can’t be easily overlooked.

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

Find Other Cases

Power Supply:

The Power Supply Of this build is actually included with the Cooler Master case itself. At 400W it can run anything this build throws at it and still has some juice left to spare. If you don’t get the case above then you need to get a Power Supply.

If you are not going with the case I provided with my build find a power supply by clicking the link below

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 1050 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 Pentium G4400 is a dual-core processor, It probably beats out anything that AMD 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 Intel’s new skylake 6th gen 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 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 Intel, this is the best budget motherboard on the market at the moment and if you ask me it easily competes with other motherboards at a higher price-range.


Entering 2016, 4gbs or RAM just isn’t enough anymore. People recommending 4gbs of RAM aren’t looking into future-proofing your Gaming PC. 4gbs atm is Ok, but games are becoming more demanding and with 8gbs you eliminate most headaches such as having to close everything when running demanding games such as GTA 5 or Far Cry 4. That’s why I included 8gb’s in this build even though I’m on such a tight budget.

Hard Drive:

This might be the builds biggest handicap. With 1TB of storage, you really have to watch what you download, but this problem is easily corrected as you can always install another hard drive or SSD in the future. This build is meant to be a build that can take on consoles and with 1TB of storage, it’s capable of doing just that.

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.

Recommended Peripherals

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 G226HQL 21.5-Inch Screen LED Monitor


Check The Acer G226HQL’s Current Price

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 – CM Storm Devastator – LED Gaming Keyboard and Mouse Combo

Check The CM Storm Devestator Combo’s Current Price

The Cool Master Storm Devastator Combo is probably the best budget keyboard and mouse you are going to find. One thing Cool Master knows how to do is make combo’s, and when you are getting an LED set that actually feels better than some $80 dollar combo sets that I’ve used then that says something. The keys feel very responsive and feel as though you are using 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 – Etekcity Scroll Gaming Headset


Check The Etekcity Scroll Headset’s Current Price

First of all, this is a really stylish headset. The Etekcity Scroll 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 Wi-Fi – EDUP 600 Wifi Adapter


Check The EDUP Wifi Adapter’s Current Price

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 EDUP 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 EDUP 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 one’s 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 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 or 10? 

I would recommend getting windows 7 premium, and if you want to you can  upgrade to windows 10 for free in the future when it becomes a more stable OS.


I seriously enjoyed making this awesome build and hope that this $400 budget gaming build really helps some of you guys make an awesome PC for the price of a console. If this build isn’t what you are looking for, you can always check out my $500 gaming build.

  1. 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.

  2. 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.

  3. 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?

    1. Post

      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.
