How to Build a Custom Gaming PC on a Budget

8 May 2025

Building your own gaming PC is one of the most rewarding tech projects you can take on. Not only do you get to customize every aspect of your build, but you also get better value for your money compared to pre-built options. However, if you’re on a budget, things can get tricky.

But don’t worry! In this guide, I’ll walk you through the step-by-step process of building a custom gaming PC on a budget without sacrificing performance. Ready? Let’s dive in!
How to Build a Custom Gaming PC on a Budget

Why Build a Custom Gaming PC Instead of Buying Pre-Built?

Before we get into the specifics, let’s address a key question: why build instead of buy?

- Cost Efficiency – Pre-built gaming PCs often have inflated prices due to labor and branding. When you build your own, you control where every dollar goes.
- Upgradability – A custom-built PC gives you more flexibility to upgrade parts later, extending its lifespan.
- Better Performance for Price – You can allocate your budget wisely, prioritizing the most critical components for gaming.
- Personalization – You get to pick the parts that match your exact needs—whether it's RGB lighting, a specific case design, or high-end cooling solutions.

Now that we’ve covered the "why," let’s move on to the "how."

Setting Your Budget

First things first—how much are we talking?

A solid budget gaming PC typically falls in the $500-$800 range. Here’s a general breakdown of how you should allocate your budget:

| Component | Estimated Budget Allocation |
|-----------------|----------------------------|
| CPU | 25-30% |
| GPU (Graphics) | 35-40% |
| RAM | 10-15% |
| Storage (SSD/HDD) | 10-15% |
| Motherboard | 10-15% |
| Power Supply (PSU) | 5-10% |
| Case | 5-10% |

These percentages will vary based on your needs, but it’s a good starting point.

Choosing the Right Components

1. Processor (CPU) – The Brain of Your PC

Your CPU determines how well your system handles multitasking and overall performance. For budget builds, AMD Ryzen 5 and Intel Core i5 are excellent choices.

Best Budget CPUs:
- AMD Ryzen 5 5600G (includes integrated graphics, saving money if you don’t buy a GPU immediately)
- Intel Core i5-12400F (great for budget gaming with a discrete GPU)

If you’re on an ultra-tight budget, go for an APU (Accelerated Processing Unit) like the Ryzen 5 5600G. This includes decent integrated graphics, letting you game without a GPU until you can afford one.

2. Graphics Card (GPU) – Your Gaming Powerhouse

The GPU is arguably the most important component for gaming. But graphics cards can be crazy expensive—so how do you get the most bang for your buck?

Best Budget GPUs:
- NVIDIA GTX 1660 Super – Solid 1080p gaming performance
- AMD Radeon RX 6600 – Great value with high frame rates in most games
- Intel Arc A750 – A new but surprisingly good budget option

If GPUs are too expensive, consider used or refurbished options from trusted sellers. Just make sure they’re in good working condition.

3. RAM – The More, The Merrier... To an Extent

For gaming, 16GB of RAM (2x8GB) is the sweet spot.

- Best Budget RAM: 3200MHz or 3600MHz DDR4 RAM kits
- Brands like Corsair Vengeance LPX and TeamGroup T-Force are great options

You don’t need 32GB of RAM unless you’re live streaming or doing heavy content creation. Stick to 16GB, and you’re golden!

4. Storage – SSD vs. HDD

An SSD is a must-have for loading games faster. A 512GB NVMe SSD is the best budget option, but if you need extra storage, add a 1TB HDD for games and media files.

Best Budget Storage Options:
- Kingston NV1 500GB NVMe SSD – Affordable and fast
- Western Digital Blue SN570 1TB – More capacity without breaking the bank
- Seagate Barracuda 1TB HDD – Cheap storage for extra files

5. Motherboard – The Backbone of Your Build

Your motherboard should:
- Support your chosen CPU
- Have enough slots for upgrades
- Offer budget-friendly features like Wi-Fi, M.2 support, and good I/O

Best Budget Motherboards:
- AMD Builds: MSI B450 TOMAHAWK MAX II
- Intel Builds: ASUS PRIME B660M-A

Buy B-series motherboards to save cash while still getting decent features.

6. Power Supply (PSU) – Don’t Cheap Out Here!

Your PSU powers everything, so don’t compromise! Aim for at least 80+ Bronze rated PSUs from reputable brands like EVGA, Corsair, or Seasonic.

Best Budget PSUs:
- EVGA 600W 80+ Bronze
- Corsair CV550 80+ Bronze

A bad PSU can fry your entire system—so go for quality over price here.

7. PC Case – Where It All Comes Together

Your case should have good airflow, cable management, and enough space for your components.

Best Budget Cases:
- NZXT H510 – Minimalist design with decent ventilation
- Cooler Master MasterBox Q300L – Great airflow at a low price
- Fractal Design Meshify C – If you can spend a little extra

Make sure your case fits your motherboard size (ATX, Micro-ATX, Mini-ITX) before buying.

Assembly – Putting It All Together

Now, let’s get to the fun part—building your PC!

Step 1: Prepare Your Workspace

- Work on a flat, non-carpeted surface to avoid static electricity.
- Gather your tools: Screwdriver, zip ties, thermal paste (if needed).

Step 2: Install the CPU & Cooler

- Lift the CPU socket latch, carefully place your CPU in (aligning the marker), and lock it in place.
- Install the cooler—either the stock one or an aftermarket model.

Step 3: Slot in the RAM & Storage

- Insert RAM sticks into the DIMM slots (check your motherboard manual for the correct placement).
- Install the NVMe SSD, securing it with a screw.

Step 4: Mount the Motherboard & PSU

- Secure the motherboard into the case.
- Install the PSU and route the power cables neatly.

Step 5: Install the GPU & Connect Cables

- Insert the GPU into the PCIe slot and tighten it with screws.
- Connect the power cables for the CPU, GPU, and motherboard.

Step 6: Power On & Install Windows

- Plug everything in, turn on the power, and boot up!
- Install Windows via USB drive and download drivers.

BOOM! You now have a custom-built gaming PC on a budget!

Final Tips for Saving Money

- Buy Used Parts Wisely – Platforms like eBay and Facebook Marketplace have great deals.
- Wait for Sales – Black Friday, Prime Day, and back-to-school sales can save you $$$.
- Start Small & Upgrade Later – Build what you can now, then improve over time.

Conclusion

Building a budget gaming PC isn’t just about being cheap—it’s about smart choices. By picking the right components and prioritizing where you spend your money, you can build a solid gaming rig without breaking the bank.

So, what are you waiting for? Get out there and start building your dream gaming PC!
