    Samsung 860 EVO 1TB SATA SSD

  • Install storage drives
  • Plug all power and data cables in where they're required (storage, case, motherboard, graphics card, etc)
  • Turn your PC on
  • Install your OS
  • Install and update ALL drivers

  • In-depth Walkthrough

    If you’ve never built a computer before, then you probably want to take some time to learn the basics before getting ahead of yourself. To do that you have a couple of options you can choose from.

    The first, and probably the easiest way for most people to learn is finding a walkthrough on YouTube from a reputable tech channel. Here’s one by BitWit as an example.

    Alternatively, I’ve put together an in-depth guide on how to build a PC as well as a FAQ to address the most common questions and problems. I've also put together a short post covering 10 of the most common mistakes people make when building.

    Recommended Add-ons/upgrades

    Below you’ll find some suggested add-ons for this build, some I’ll mention more in-depth further down this page, but some are pretty self-explanatory like optical (DVD/CD) drives and your operating system.

    q? encoding=UTF8&ASIN=B075RM5BHV&Format= SL110 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=websitepcgame 20&language=en USir?t=websitepcgame 20&language=en US&l=li1&o=1&a=B075RM5BHV

    Windows 10 (USB Installer)

    Windows 10 is your best bet when it comes to picking an operating system. This version is a USB installer.

    q? encoding=UTF8&ASIN=B07HY6QWXN&Format= SL110 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=websitepcgame 20&language=en USir?t=websitepcgame 20&language=en US&l=li1&o=1&a=B07HY6QWXN

    Asus RTX 2080 Ti ROG Strix

    They’re expensive, but an RTX 2080 Ti is the best GPU on the market right now.

    q? encoding=UTF8&ASIN=B06XX8Q1CL&Format= SL110 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=websitepcgame 20&language=en USir?t=websitepcgame 20&language=en US&l=li1&o=1&a=B06XX8Q1CL

    NZXT Kraken X62

    Instead of air cooling, another option is an all-in-one liquid cooler like the 240mm NZXT Kraken X62.

    portable DVD writer

    Samsung Ultra-Slim External CD DVD±R/RW

    A lot of people are moving away from internally mounted optical drives, and it’s easy to see why! This one is definitely one of the cheaper & better external optical drives to consider.

    Build Breakdown

    This is the ultimate single GPU 4K gaming PC build, without a doubt. It hasn't been until the release of the GTX 1080 Ti that a single card 4K build was even really possible without lowering the settings so low that gaming wouldn't be enjoyable anyway.

    Keep in mind that the price listed above is just for the core components and you will still need to add anything that you don't already have; mouse, keyboard, audio, those kinds of things.

    Case: NZXT's H510i is an upgrade on their previous H500i and before it, the S340 - some of the best cases of previous years. The H510i improves on the old design and offers great airflow options as well as a great layout that caters to clean cable management.

    The best PC fan is super important to protect your gaming rig. This case comes with a built-in RGB/fan controller, 2x Aer F120mm fans, and RGB light strips to add some feature lighting. It's built entirely from steel and although that makes it heavy, it also makes it very durable and gives it the high-quality feel this case deserves.

    NZXT's H510i case

    Motherboard: The Gigabyte Z390 Aorus PRO is a high-end LGA 1151 socket, Z390 chipset, ATX motherboard that's perfectly suited for this build.

    The Z390 Aorus PRO has all of the ports, headers and slots you'll need for everything in this build, and then some. Including built-in 7.1 audio, an Ethernet controller, a total of 10x USB ports, 2x M.2 slots, numerous case fan headers, support for custom watercooling, and even built-in RGB lighting.

    The Gigabyte Z390 Aorus PRO

    Processor (CPU): Intel's 8 core/16 thread i7 9700K is a complete and utter beast when it comes to pretty much anything. It's unlocked, so you can overclock it if you wish, but you won't have to because it readily blows most other CPUs clean out of the water. The i9 9900K is an all-around incredible CPU regardless of what you're using it for.

    Since the i9 9900K does not come with a stock CPU cooler, I've added on a be quiet! Dark Rock 4 to keep you covered. It's an awesome air CPU cooler and will keep your 9900K cool, even while lightly overclocked. If you would prefer a closed loop liquid cooler instead, I'd suggest checking out something like the NZXT Kraken X62!


    Graphics Card (GPU): The 8GB GDDR6 RTX 2080 Super is a complete and utter powerhouse when it comes to gaming. It completely blows away the last generation's GTX 1080 Ti and especially its little brother the GTX 1080. Simply put, the RTX 2080 Super is one of the best cards you could buy right now in terms of sheer gaming performance! It's only outmatched by the far more expensive RTX 2080 Ti or a $3000 Titan.

    8GB GDDR6 RTX 2080

    Asus's ROG STRIX RTX 2080S is absolutely no exception. It comes factory overclocked and features some of the best cooling you could have on a GPU - plus some decent RGB lighting. For connectivity, it has 2x HDMI, 2x DisplayPort, 1x USB Type-C, making it 100% VR ready.

    As I mentioned, the only way to get a stronger GPU is upgrading to an RTX 2080 Ti, but on its own, it costs a little over 50% of what this entire build does.

    System Memory (RAM): 16GB of DDR4 RAM is more than enough for any dedicated gaming PC. With that in mind, I picked you out 16GB of Kingston's HyperX Predator RGB RAM at 3200MHz.

    If you feel that you might need more than 16GB, maybe because you want to try streaming or something like that, I'd suggest grabbing the 32GB kit instead.

    System Memory

    Power Supply (PSU): Seasonic's Focus+ Gold 650W is a top-level fully-modular power supply that offers a platinum level of efficiency for the cost of a gold-rated supply. It can reach 90% efficiency at 50% load and 87% efficiency at 100% load, it also boasts heavy-duty OVP, UVP, OCP, OPP, and SCP protections.

    Power Supply

    At only 140mm deep, the Focus+ 650 can easily fit inside of practically any case you might want to use. Its fully-modular platform allows for clean and concise cable management. On top of all of that, it even features a lengthy 10-year warranty just-in-case something not-ideal were to happen.

    Storage: As far as storage goes, 1.5TB of pure SSD storage is either really excessive or not excessive enough. Depending on which way you see it, this build has an insane amount of potential in terms of storage configurations. So, feel free to customize it as you see fit!

    There's also a reason for the two drives, the faster NVMe SSD is meant to be your primary boot drive (where Windows and your primary programs are installed) and maybe a couple of your more load-intensive games. Then, the SATA SSD is meant to be used as a mass storage drive (for the bulk of your games, etc). This type of setup will ultimately make your PC perform better than having everything on a single drive.

    This build is completely capable of playing AAA games in 4K at 60fps, less intensive games will run at much higher frame rates and you might even hit 144+ depending on the game!

    Operating System

    When it comes to picking out an operating system, you pretty much have two options.

    Windows, or Linux.

    Windows is the better of the two when it comes to out-of-the-box compatibility with programs and games; but Linux is favored by more advanced PC users for its heightened security and its ability to be heavily modified.

    Windows Home

    The choice comes down to which one you prefer. Generally speaking, I'd recommend going the Windows 10 route unless you're already familiar with Linux.


    If this is your very first PC, chances are you're lacking things like a mouse, keyboard, monitor and some kind of audio peripheral. If that's the case, take a look through the items listed below for some of my recomendations.

    q? encoding=UTF8&ASIN=B078HWN5CX&Format= SL110 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=websitepcgame 20&language=en USir?t=websitepcgame 20&language=en US&l=li1&o=1&a=B078HWN5CX

    BenQ EL2870U

    A great 28-inch 4K monitor with HDR10, Freesync, and a 1ms GTG response time. Has both HDMI and DisplayPort.

    q? encoding=UTF8&ASIN=B01N5IISXY&Format= SL110 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=websitepcgame 20&language=en USir?t=websitepcgame 20&language=en US&l=li1&o=1&a=B01N5IISXY

    Kingston HyperX Cloud II

    The best gaming headset you can get, in my opinion.


    WiFi is never the ideal solution for a gaming PC's internet connection. Just due to the nature of how WiFi works, it will almost always be inferior to a wired connection. That said, if you absolutely need/want to use a WiFi connection, you're going to need a WiFi adapter.

    q? encoding=UTF8&ASIN=B016K0896K&Format= SL110 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=websitepcgame 20&language=en USir?t=websitepcgame 20&language=en US&l=li1&o=1&a=B016K0896K

    Internally mounted dual-band AC1300 WiFi adapter. Operates on both 2.4 and 5GHz bands.

    q? encoding=UTF8&ASIN=B07P6N2TZH&Format= SL110 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=websitepcgame 20&language=en USir?t=websitepcgame 20&language=en US&l=li1&o=1&a=B07P6N2TZH


    One of the best USB-based AC1300 dual-band WiFi adapters.


    This is the ultimate single card 4K gaming PC build this far into 2018. It'll handle AAA games at 4K resolutions while putting out 60fps or better, less intensive games are going to run at significantly higher fps and you'll exceed 144fps in quite a few.

    If you came here looking for an awesome build for $2000, or you want the best single card 4K build you can find, this one is it, without a doubt.

    If you have any questions about the build or the suggested peripherals, feel free to ask me in the comment section or check out this FAQ!

    I added up the prices for the all pieces and it was $3,750 ish. Heck even one part was $1,700. Am I doing something wrong?

    It might be because of Covid and all of the part prices are up.

    Hey Branton, will the motherboard H170N Mini-ITX will work with the i9 that you recommend with this build? Here is the link to the motherboard I am mentioning. https://www.amazon.com/gp/product/B015CQ8D46/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

    Hey Branton! how is the i9-9900k compared to the AMD Ryzen 9 3900X? which would be better in terms of gaming performance and longevity?

    Hey! Looking to build my first 2020 gaming PC! I bought a prebuld PC in 2018 to stream and play but now I want something stronger to handle any games on high settings and my own build. I like the $2000 set up. However , do I just upgrade my pre build pc or wait for the RTX ?

    Are all this computer components upgradable?

    And how far past can 60fps can the games actually go? For a $2000 computer games should be running in 120 fps

    Reply to  Mark smith

    theyre talking about high res games at max settings, on a game like fornite this could asily run 300fps on low and probably 200 on epic

    November 16, 2019 9:05 am

    I’ve been a long time fan of the Total War series but could never play any of the games on the highest graphics settings. Would this be able to run the newest game (Total War: Three Kingdoms) on its highest setting?

    Good to hear! In that case it looks like I’ve found my build haha. Really love this site and the builds put on it, makes things so much easier for the less PC savvy people like myself haha.
