This makes your custom gaming pc build future-proof for upcoming hardware releases.

Step 5: Check deals and bundles

In 2025, GPU and CPU prices have stabilized compared to the chaos of previous years, but deals still vary by season.
Keep an eye on sales events like Black Friday, Prime Day, or Newegg Gamer Week – you can often save $100–$300 on a full beginner gaming pc build.

Quick Pro Tip

If you’re new to this, avoid prebuilt systems that promise “ultra performance” for suspiciously low prices. Building it yourself ensures you know exactly what’s inside, and you can easily upgrade down the line.

Step-by-step assembly: how to build your gaming PC (for beginners)

Here’s where the magic happens – the assembly process. Whether you’re building a best budget gaming pc or a high-end powerhouse, these steps remain mostly the same. So grab your screwdriver, ground yourself (literally – static discharge is no joke), and let’s build your dream rig!

Step 1: Prepare your workspace

Before you even touch the components, find a clean, well-lit surface – ideally a table big enough for your PC case and parts. Avoid carpeted floors; static can damage sensitive components.

You’ll need:

• Phillips screwdriver (preferably magnetic)
• Anti-static wrist strap
• A small bowl or tray for screws
• Patience (lots of it)

Pro tip: Keep your manuals nearby – every motherboard and case is slightly different.

Step 2: Install the CPU

1. Open your motherboard’s CPU socket latch carefully.
2. Align the CPU’s triangle mark with the one on the socket – it only fits one way.
3. Gently lower the CPU into place and lock it down.

Don’t force it. CPUs are like puzzle pieces – they only fit one way, and breaking a pin is heartbreak in silicon form.

Step 3: Add your cooler

If you’re using the stock cooler, attach it with the pre-applied thermal paste facing the CPU. For aftermarket coolers, apply a small pea-sized amount of thermal paste before mounting.

Tighten screws evenly and connect the CPU fan cable to the CPU_FAN header on your motherboard.

Step 4: Install your RAM

Open the RAM slots by pressing the clips outward.
Insert the RAM sticks into alternating slots (check the motherboard manual for the correct configuration).
Push until you hear a click – that sound means victory.

Screw it in gently – don’t overtighten.
Plug in the 24-pin power cable and the 8-pin CPU cable from your power supply later once it’s installed.

Step 6: Install the power supply (PSU)

Slide your PSU into the bottom or rear compartment of your case (depending on design).
Ensure the fan faces the correct direction – usually outward or downward toward ventilation holes.
Secure it with four screws and keep the cables tidy.

Step 7: Add storage drives

Insert your NVMe SSD into the M.2 slot on the motherboard and secure it with a tiny screw.
For additional SSDs or HDDs, mount them in drive bays and connect them via SATA cables.

Step 8: Install your GPU

Now, for the star of the show.

1. Remove the PCIe slot covers from your case.
2. Insert your GPU into the top PCIe x16 slot until it clicks.
3. Screw it securely to the case frame.
4. Plug in the PCIe power connectors from your PSU.

This is the moment you’ll probably take a photo – and yes, you’ve earned it.

Step 9: Connect case cables

This part can test your patience. Connect:

• Front panel connectors (power switch, reset, LED)
• USB 3.0 / USB-C headers
• Audio header
• Case fans to motherboard fan headers or fan hubs

Your motherboard manual will be your best friend here.

Step 10: First power-on test

Before you close everything up, perform a test boot.

1. Connect the PSU to power.
2. Press the power button.

If you see fans spinning and lights turning on – congrats! If not, check power cables and CPU/RAM seating.

Once you get a signal on your monitor (the BIOS screen), you’ve officially succeeded in your ‘how to assemble a gaming pc’ mission.
