Building a Gaming PC from Scratch in 2025
Building your own gaming PC might sound complicated but it’s actually a lot of fun and easier than you think. With all the advancements in technology, it’s the perfect time to try it. For a seasoned gamer or just starting out, this guide will show you the most important information you need to start building!
Step 1: Set The Budget
First figure out how much you’re willing to spend. Gaming PCs can range from cheapish to I just spent my entire paycheck levels, so it’s important to know your limits. This is a quick breakdown of what to expect in 2025:
- Budget Build ($800-$1,200): Perfect for 1080p gaming and everyday tasks.
- Mid-Range Build ($1,200-$2,000): Handles 1440p gaming and streaming like a pro.
- High-End Build ($2,000+): Ideal for 4K gaming, VR, and future-proofing.
Once you’ve set your budget, try to stick to it but be willing to add a bit more if it’s making a big difference for you. It’s easy to get tempted by incremental upgrades, but you can always add more later.
You can always add more later also means to keep in mind parts future proofing such as getting a motherboard with the latest PCIE version so that it will last you longer.
Step 2: Choose Your Components
This is the fun part! Picking out the parts that will make your PC. Many nicely colored boxes with nice shiny stuff inside waiting to pulled out of their packages.
What you’ll need:
- Processor (CPU): The brain of your PC. In 2025, AMD and Intel are still the top choices. Look for at least 6 cores for smooth gaming.
- Graphics Card (GPU): This is what makes your games look amazing. NVIDIA and AMD are the leaders as usual. If you want the fancy ray-tracing effects, make sure your GPU supports it.
- Memory (RAM): 16GB is the sweet spot for gaming in 2025, but if you’re into multitasking or streaming, go for 32GB.
- Storage: An NVMe SSD (1TB is a good start) will give you fast load times. Add a larger HDD if you need extra space for games and files.
- Motherboard: Make sure it’s compatible with your CPU and has enough ports for your needs.
- Power Supply (PSU): Don’t skimp here! Get a reliable PSU with enough wattage for your components.
- Case: Choose one that fits your style and has good airflow. Make sure it’s compatible with your motherboard size (ATX, Micro-ATX, etc.).
- Cooling: Stock coolers are fine for budget builds, but consider an aftermarket air cooler or liquid cooling for high-end setups.
- **Peripherals ** PC Monitor or Screen, Keyboard and Mouse are the bare minimum. Add speakers / headphones and a printer if you need to print.
Step 3: Assemble Your PC
Time to get your hands in and unbox everything! Here’s how to put it all together:
- Prepare Your Workspace: Clear a table, get a phillips head a screwdriver, and ground yourself to avoid static damage (just touch a grounded metal object before handling components).
Take the motherboard out of its box and place it on top of it’s anti-static shoelding bag. - Install the CPU: Carefully place the CPU into the motherboard socket. It should drop right in without any force.
- Attach the Cooler: Follow the instructions for your cooler. Apply thermal paste if it’s not pre-applied.
- Install RAM: Push the RAM sticks into the slots until they click. Check your motherboard manual for the correct slots.
- Mount the Motherboard: Secure it to the case using the included screws.
- Install the GPU: Slot it into the PCIe slot on the motherboard and screw it into the case.
- Connect Storage: Mount your SSD/HDD in the case and connect it to the motherboard and PSU.
- Wire Everything Up: Connect the power supply to the motherboard, GPU, and storage. Don’t forget the case fans and front panel connectors (power button, USB ports, etc.).
- Double-Check Connections: Make sure everything is securely connected before closing the case.
- Connect PC monitor to power and Display port or HDMI out ports on the GPU.
- Connect keyboard and mouse to USB ports at the back of the PC. Slowest USB 2.0 ports are fine for this unless your keyboard has a built-in USB 3.0 or 3.2 gen 2 hub then you need to plug in the keyboard USB cable into a fast port on the motherboard.
Step 4: Install the Operating System
Now that your PC is built, it’s time to start it finally but you’re not done yet:
- Create a Bootable USB: Download Windows (or your preferred OS). For Windows use the Media Creation Tool to create a bootable USB drive.
- Boot from USB: Plug the USB into your PC, power it on, and enter the BIOS (usually by pressing DEL or F2 during startup). Set the USB as the boot device.
- Install the OS: Follow the on-screen instructions to install Windows or another OS.
- Install Drivers: Download the latest drivers for your GPU, motherboard, and other components from the manufacturers’ websites.
Step 5: Test It
Your PC is up and running—great job! Now, let’s make sure everything’s running well:
- Run Benchmarks: Use tools like 3DMark or Cinebench to test performance.
- Monitor Temperatures: Check that your CPU and GPU aren’t overheating during gameplay.
- Optimize Settings: Tweak in-game settings for the best balance of performance and visuals.
- Keep It Clean: Regularly dust your PC and update drivers to keep it running cool like new.
