How to Build a Gaming PC: The Ultimate Guide for 2023

Building your own custom gaming PC can be an extremely rewarding hobby that allows complete personalization and better performance for the money compared to pre-built systems.

This comprehensive guide will walk you through everything you need to know about assembling your own high-end gaming computer from start to finish.

Step 1: Determine Your Budget

The first step is deciding how much money you want to spend on your new custom gaming rig. PC builds can range drastically in budget from just a few hundred dollars for entry-level setups to $5,000+ for top-of-the-line systems.

As a benchmark, aim for spending around $800 – $1,500 if you want a gaming PC that can handle modern games at 1080p resolution and high settings.

Here is an approximate budget breakdown for a mid-range PC:

  • PC Case – $50 to $100
  • CPU (Processor) – $200 to $300
  • CPU Cooler – $50 to $100
  • Motherboard – $100 to $200
  • RAM – $60 to $120
  • Graphics Card – $300 to $600
  • SSD Storage – $50 to $100
  • Power Supply – $50 to $150
  • Operating System – $90 to $110
  • Monitor – $150 to $300
  • Peripherals – $50 to $150

Of course, you can spend less or more within each component category depending on your exact performance needs and budget.

Step 2: Select Your CPU (Processor)

Your PC’s central processing unit (CPU), commonly referred to as a processor, is one of the most important components. It handles essential computation tasks and directly impacts overall system performance.

For gaming, some top CPU choices include:

  • Intel Core i5/i7/i9 – Excellent performance for high-end gaming and multitasking. Models include 10th/11th/12th Gen Core i5, i7 and i9.
  • AMD Ryzen 5/7/9 – Great value CPUs ideal for gaming. Look for Ryzen 3000, 5000 and 7000 models.

Ideally, choose a more recent generation CPU with 6, 8 or even 12 cores. Expect to spend around $200 to $500+ on your processor depending on exact model.

Step 3: Select Your GPU (Graphics Card)

The graphics processing unit (GPU), or graphics card, handles rendering all the complex graphics when gaming. The GPU significantly impacts gaming visuals and performance.

Some popular options:

  • NVIDIA GeForce RTX – NVIDIA’s RTX 3000 series cards like the RTX 3060 or RTX 3070 offer phenomenal value for 1080p and 1440p gaming. Expect to spend around $300 to $800.
  • AMD Radeon RX – AMD also makes powerful GPUs suitable for gaming like the RX 6600 XT and RX 6800 XT in the $300 to $700 range.
  • NVIDIA GeForce GTX 1660 – Older generation budget cards like the GTX 1660 and GTX 1660 Ti are lower cost options under $300.

Ideally, aim for at least a GeForce RTX 3060 or Radeon RX 6600 XT tier card for smooth high fidelity gaming. Avoid any cards under 4GB of VRAM.

Step 4: Choose Compatible RAM

Your gaming PC will need sufficient random access memory (RAM) to handle running graphics-intensive games smoothly.

For modern systems, 16GB of RAM is recommended at minimum for ideal performance. But you can get by with 8GB if on a tight budget.

For RAM speed, aim for at least DDR4-3200 memory or faster. Focus on low CAS latency as well for responsiveness.

Any DDR4 RAM from top brands like Corsair or G.Skill that meets these specs will work great. Expect to pay around $60 to $150 for 16GB depending on speed.

Step 5: Pick Your Storage

Gaming PCs need fast and spacious data storage. Here are the best options:

SSD (solid state drive):

  • 500GB to 1TB SSD for your operating system, core applications and some games ($50 to $100).
  • M.2 NVME SSD for blazing transfer speeds if your motherboard supports it.

HDD (hard disk drive):

  • 2TB to 4TB 7200RPM HDD for storing your entire gaming library and files long term ($60 to $100).

Using a smaller SSD for your OS and apps paired with a larger HDD for data storage gives you the perfect combo of speed and capacity.

Step 6: Select a High-Quality Power Supply

Never cheap out on your PC’s power supply unit (PSU). A low-end PSU can damage components.

For a mid-range gaming PC, a 550W to 750W 80+ Gold certified PSU from reputable brands like Corsair, EVGA or Seasonic is recommended. Expect to pay $70 to $150.

Higher-end PSUs with fuller modularity and premium efficiency ratings provide more headroom for growth. But a 80+ Gold PSU with at least 550W or more capacity will work great for most gaming setups.

Step 7: Choose a Compatible Motherboard

The motherboard is the central PCB circuit board that connects all your components together. For gaming PCs, focus on boards with compatibility for modern CPUs, plenty of RAM slots, M.2 connectors and PCIe x16 slots for graphics cards.

For Intel CPUs, Z690 and B660 chipset motherboards offer excellent performance. For AMD, X570, B550 and X370 chipsets have great gaming support. Expect to pay $100 to $300+ depending on features.

Top brands like ASUS, MSI, Gigabyte or Asrock make quality options. Just make sure your specific CPU socket and RAM generation is supported.

Step 8: Pick a Gaming Case You Like

Your PC case houses all components and reflects your style. Look for cases with:

  • Solid airflow from multiple cooling fans
  • Dust filters to maintain cleanliness
  • Ample interior space for components
  • Room for future expansion and upgrades

Premium gaming cases from brands like NZXT, Corsair, Cooler Master or Lian Li offer excellent quality for around $100 to $200. But good budget cases exist for $50 as well.

Choose based on your budget, preferred aesthetics and desired features like RGB lighting or tempered glass panels.

Step 9: Assemble the Physical Build

Once you have all your components and case, it’s time for the fun part – actually building your PC!

Here are the general steps for physically constructing your system:

  1. Unbox all components and prepare your case by removing any drive bay covers needed.
  2. Install the CPU, CPU cooler, RAM modules and M.2 SSD onto the motherboard if applicable.
  3. Mount the motherboard inside the case using included standoffs and screws, usually near the back panel.
  4. Connect front panel wires from the case to the motherboard header.
  5. Insert the power supply into its case mount and connect all necessary PSU cables.
  6. Attach any 2.5”/3.5” drives into open drive bays with SATA cables.
  7. Insert your graphics card into a PCIe x16 slot and connect power cables from PSU.
  8. Manage all cables neatly using cable ties and channels. Close up the case.

Consult your motherboard manual thoroughly, work carefully, and don’t force components. The process takes a few hours for beginners but is very rewarding.

Step 10: Install Your Operating System

After completing the physical PC build, it’s time to install your OS and get everything running!

For gaming PCs, Windows 10 or Windows 11 are the ideal operating systems. You can download and install Windows 10 for free, or purchase a license key to unlock full customization.

To install, you’ll need an 8GB+ USB flash drive. Use the Media Creation Tool to load the OS installer onto the drive. With your new PC powered on, boot into the flash drive BIOS menu and select it as the boot drive to begin installing Windows.

Follow the on-screen prompts while letting Windows install necessary drivers. Once complete, boot into your fresh OS!

Step 11: Install Components and Peripherals

After Windows is set up, install and update any remaining components and peripherals:

  • Motherboard chipset/GPU drivers
  • Gaming mouse, keyboard, headset etc.
  • Fans and RGB lighting controllers
  • External optical drive if needed
  • WiFi adapter or ethernet cable

Visit your motherboard OEM’s site to find the latest chipset, audio and networking drivers. Keep all system software, drivers and Windows updated.

Step 12: Overclock Components (Optional)

One of the appeals of custom gaming PCs is overclocking components to push even more performance out of your rig.

Overclocking isn’t for complete beginners, but tools like MSI Afterburner make overclocking GPUs straightforward. You can also overclock CPUs, RAM and more with some BIOS tweaking.

Do ample stability testing at incrementally higher clock speeds. Stop overclocking if system crashes or components overheat. Conservative overclocks of around 5-15% can comfortably boost FPS and speed without issues. But take it slow!


Building your own gaming PC is deeply rewarding and results in better performance per dollar compared to pre-builts.

Carefully choose components that fit your budget while allowing future upgrades. Take your time meticulously assembling the physical build.

With quality parts, sensible component selections and a methodical assembly process, you can construct an awesome custom gaming rig perfect for your needs as a PC gamer.
