Step-by-Step Guide to Building a PC on a 3D PC Building Website

Step 1: Choose a reliable 3D PC building platform

Start by selecting a well-reviewed 3D building platform that fits your needs, with options that include real-time part pricing, compatibility checks, and full 3D visualization features. Popular options have large libraries of up-to-date parts from all major manufacturers, so you can find exactly what you’re looking for. You can create a free account on most platforms to save your builds as you work.

Common mistake to avoid: Don’t use outdated platforms that don’t update their part libraries regularly, as you may pick components that are no longer available or have inaccurate compatibility data.

Step 2: Define your build goals and budget

Before you start picking parts, decide what you primarily want to use the PC for, such as gaming, content creation, school work, or office use, and set a rough budget you want to stay within. This will help the platform filter appropriate part recommendations and prevent you from overspending on features you don’t need. You can always adjust your budget later as you explore different part options.

Pro tip: Allocate roughly 30-40% of your budget to your GPU if you’re building a gaming PC, or to your CPU if you’re building for video editing or 3D rendering work.

Step 3: Select your core components with compatibility checks

Start picking your core parts in order of priority: first your CPU, then your compatible motherboard, RAM, storage, GPU, power supply, and case. The platform will flag any compatibility issues as you select each part, such as a CPU that won’t fit your motherboard or a power supply with insufficient wattage. Take time to compare performance benchmarks and user reviews for each part before making a selection.

Common mistake to avoid: Don’t pick a case before you select your motherboard and GPU, as some larger parts won’t fit in smaller compact case designs.

Step 4: Assemble your build in the 3D workspace

Once you have all your core parts selected, enter the platform’s 3D assembly mode to digitally put your PC together step by step, just like you would in real life. This lets you see exactly how each part fits into the case, check cable routing space, and make sure all components have enough airflow to stay cool during use. You can rotate and zoom the 3D view to inspect every angle of your build.

Pro tip: If you’re new to PC building, follow the platform’s guided assembly prompts to learn the correct order to install parts, which will make your physical build much easier later.

Step 5: Test performance and adjust your build as needed

Most 3D building platforms offer estimated performance benchmarks for popular games and software based on your selected parts. Review these metrics to see if your build meets your performance goals, and swap out parts if you need faster speeds or want to cut costs. You can also adjust your part selections to stay within your original budget without losing too much performance.

Common mistake to avoid: Don’t overspend on high-end parts that offer only small performance gains for your specific use case, as this will stretch your budget unnecessarily.

Step 6: Save and export your final build plan

When you’re happy with your 3D build, save it to your account and export the full parts list, which typically includes current pricing from different retailers, part model numbers, and direct purchase links. You can also generate a shareable link to send your build to friends or online communities to get feedback before you buy any parts. Many platforms also offer step-by-step physical build guides based on your exact part selections.

Pro tip: Check if the platform offers price alert features, so you can get notified when any of your selected parts go on sale to save extra money on your purchase.

Challenges to Be Aware Of

Part availability and pricing discrepancies: The platform’s listed prices and stock status may not always match real-time retailer updates, so you may need to cross-check prices before making a purchase. You can mitigate this by setting price alerts and checking multiple retailer sites when you’re ready to buy parts.
Learning curve for advanced features: If you want to use more complex features like custom water cooling or overclocking simulations, you may need to spend extra time learning how those tools work within the platform. Most platforms offer free tutorials for these advanced features if you want to expand your skills.
Overwhelm from too many part options: New builders may feel overwhelmed by the thousands of available parts, especially if they don’t have clear performance goals. Start with the platform’s pre-made build templates for your use case, then adjust parts as you learn more about what you need.
