Things to Know Before Building a PC
Building a PC isn’t just about putting parts together; it involves planning and understanding your goals. Ask yourself:
- What will you use the PC for?
- Gaming, streaming, content creation, or office work?
- What’s your budget?
- Prices range from $800 to $3000, depending on the build.
- Do you want to upgrade in the future?
- Choose a motherboard that supports expansion options.
- Should you buy or build?
- DIY builds give you control and customization, but pre-built PCs offer convenience.
Once you answer these questions, you’ll know which parts to buy.
Components Required to Build a PC
A successful build requires the right parts. Each component has a specific function and needs to be compatible with others. Here’s a breakdown:
1. Processor (CPU) – The Brain of the Computer
The CPU handles all major calculations and controls how quickly your PC performs tasks.
- Top Picks in 2024:
- AMD Ryzen 7800X3D for gaming.
- Intel Core i9-14900K for multitasking and heavy workloads.
The best CPU build for gaming focuses on cores, clock speed, and gaming optimization.
2. Graphics Card (GPU) – For Gamers and Creators
A GPU processes images and video, ensuring smooth performance.
- Latest GPUs: NVIDIA RTX 5000 series and AMD RX 7900 XT.
- Features: Ray tracing, VR support, and AI-based graphics enhancements.
If you’re following Tom’s Guide on how to build a gaming PC, a high-end GPU is essential.
3. Motherboard – The Backbone of Your PC
The motherboard connects all components. Make sure the CPU, GPU, and RAM are compatible with it.
- Look for PCIe 5.0 slots for future GPU upgrades.
- Choose a model with Wi-Fi 7 and multiple USB ports for convenience.
4. Memory (RAM) – Speed and Multitasking
- Minimum: 16GB DDR5 for most tasks.
- Recommended for Gaming: 32GB DDR5.
- RAM speeds directly affect how fast programs load and run.
5. Storage – Fast Loading Times with SSDs
Storage determines how quickly your PC boots and loads files.
| Type | Speed | Recommended Use |
|---|---|---|
| NVMe SSD | Extremely fast | Boot drive, gaming |
| SATA SSD | Fast, but cheaper | Secondary storage |
| HDD | Slow, but affordable | Backups, media storage |
NVMe SSDs ensure your PC runs at top speed, while HDDs provide extra storage space.
6. Power Supply Unit (PSU) – Reliable Power Source
Your PSU powers all components. Calculate how much wattage your system needs, typically between 650W and 850W for gaming builds.
- Use 80 Plus Gold or higher-rated PSUs for better efficiency.
- Modular PSUs help with cable management.
7. Cooling System – Keep Temperatures Low
Keeping your PC cool ensures stable performance.
- Air cooling: Easier to install and cheaper.
- Liquid cooling: Better for high-performance systems.
Proper cooling prevents thermal throttling, which slows down your system under high temperatures.
8. PC Case – Protection and Airflow
The case houses all components. Ensure it fits your GPU size and has enough room for cooling fans. Cases with RGB lighting are popular for gamers.
How to Build a PC from Scratch: Step-by-Step Assembly
Here’s a straightforward step-by-step guide to assembling your PC.
Step 1: Install the CPU First
Begin with the CPU since it’s the most critical component.
- Open the CPU socket on the motherboard.
- Align the gold triangle on the CPU with the socket.
- Gently place the CPU in the socket and close the latch.
This answers the common question: “When building a PC, what do I install first?” It’s the CPU!
Step 2: Attach the RAM Modules
- Open the RAM slots on the motherboard.
- Insert the RAM sticks until they click in place.
- Install them in alternating slots for dual-channel performance.
Step 3: Install the SSD or HDD
- Secure the NVMe SSD into the designated slot on the motherboard.
- For SATA drives, connect the power and data cables to the drive and motherboard.
Step 4: Mount the Motherboard in the Case
- Install the motherboard’s I/O shield into the case.
- Align the motherboard with the standoff screws and secure it in place.
Step 5: Add the Power Supply (PSU)
- Place the PSU at the bottom of the case.
- Route the cables through the back panel for a cleaner look.
Step 6: Install the Graphics Card (GPU)
- Insert the GPU into the PCIe slot on the motherboard.
- Secure it with screws to prevent movement.
Step 7: Connect the Power and Cables
- Use the PSU cables to power the motherboard, GPU, and storage.
- Plug in the case’s front panel connectors to the motherboard.
Step 8: Test and Boot Your PC
- Plug in your monitor and keyboard.
- Turn on the PC and enter the BIOS menu.
- Ensure the system detects all components.
If your PC boots successfully, congratulations! You’ve built your own computer from scratch.
