Initializing...
Plan, compare, and configure your perfect custom PC. Free. No account. No guesswork.
Explore
Browse GPUs, CPUs, motherboards, RAM, storage, coolers, power supplies, and cases - all with full specifications, real benchmark scores, and current market price ranges. Click any part to see everything about it instantly.
Budget
Set a price and a use case - gaming, productivity, or balanced - and our recommendation engine allocates spending across categories using performance-per-dollar ratios. The result: the best possible build at your exact price point.
Compatibility
Socket mismatch. Wrong RAM type. Underpowered PSU. Our compatibility engine checks every connection in your build in real time and flags issues the moment they appear - not after you’ve already ordered.
Performance
Every component carries a normalized performance score derived from 3DMark Time Spy, Cinebench R23, CrystalDiskMark, and PassMark. Compare parts based on how they actually perform, not what the box says.
Power
See total system power draw update live as you add each component. Know your PSU headroom, avoid thermal throttling, and pick the right cooling solution for your build.
Share
Builds save automatically in your browser. Share yours with anyone using a compact URL - they see your exact configuration loaded instantly. No accounts needed on either end.
Building a custom PC can feel overwhelming, especially if you are doing it for the first time. With hundreds of components across dozens of categories, choosing the right parts that work together within your budget is a challenge. Build Your Setup was built to simplify that process. Our free online PC builder gives you everything you need to plan a custom gaming PC, productivity workstation, or general-purpose desktop without spending hours cross-referencing spec sheets and compatibility lists.
Unlike basic part-picker tools that only list components, Build Your Setup provides an interactive visual experience. Browse through GPUs from NVIDIA and AMD, explore the latest Intel and AMD Ryzen processors, pick the right motherboard chipset, select DDR5 or DDR4 RAM at the right speed, choose NVMe or SATA storage, and configure your cooling solution and power supply - all in one place with real-time feedback on compatibility and total system power draw.
Our recommendation engine does not guess. It uses normalized performance scores derived from published benchmarks. For GPUs, scores come from 3DMark Time Spy, Fire Strike, and PassMark tests. For CPUs, we weight Cinebench R23 single-core and multi-core results based on your selected use case. Gaming builds prioritize single-thread performance and GPU power, while productivity builds weight multi-thread throughput and fast storage higher.
When you set a budget, the engine allocates spending across categories using proven ratios. A gaming-focused build directs more budget toward the GPU, while a balanced build spreads funds more evenly. You can always override any recommendation and pick components manually - the tool adapts to your choices and continues checking compatibility regardless of how you build.
We display researched market price ranges for every component based on pricing data gathered from Amazon, Newegg, Best Buy, B&H Photo, and Micro Center. These are typical price ranges, not live feeds. For every component, we provide direct links to major retailers so you can check current pricing and availability. Build Your Setup does not sell components directly and does not earn affiliate commissions.
Build Your Setup runs entirely in your browser. Your build configuration, theme preference, and budget settings are stored locally on your device - never on our servers. There is no account to create, no email to verify, and no data to worry about. Whether you are researching parts for a budget gaming PC under $800 or planning a no-compromise enthusiast setup with the latest RTX 4090 and Ryzen 9 7950X, Build Your Setup gives you the tools to build with confidence.
Everything you need to know about building your PC with our tool.
Build Your Setup is an interactive, visual PC planning and comparison tool. Unlike traditional calculators that just check if cables plug in, our engine analyzes your component choices to detect performance bottlenecks, estimate real-world game frame rates, and optimize your budget allocation.
Yes, 100% free. There are no paywalled features, no premium tiers, and no hidden subscriptions.
We aggregate historical market data from major hardware retailers (including Amazon, Newegg, Best Buy, B&H Photo, and Micro Center) to provide realistic target price ranges. Because hardware market prices fluctuate rapidly, these act as baseline estimates to help you budget effectively before you shop.
Absolutely. Your configuration saves automatically directly to your browser's local storage as you work. You don't need to log in or create an account to save your progress.
Our physical and electronic validation engine checks your build in real time. It flags socket mismatches (like trying to put an AMD chip in an Intel board), memory generation mismatches (DDR4 vs DDR5), dimensional conflicts (large GPUs inside mini-ITX cases), and power supply constraints.
Our recommendation engine relies entirely on clean, normalized hardware benchmark data from synthetic runs like 3DMark Time Spy and Cinebench R23, combined with real-world in-game telemetry data. Ratios are adjusted based on whether your target profile is pure gaming, rendering/productivity, or a balanced build.
No. Build Your Setup is purely a planning and validation platform. We do not sell hardware directly, handle inventory, process transactions, or run dynamic affiliate links. We simply provide clean data to help you shop confidently at your preferred retailers.
When you click "Share," our tool generates a unique, highly compressed URL query string containing your exact part choices (e.g., buildyoursetup.com?build=gpu-4090...). Anyone who clicks that link will instantly see your exact setup loaded into their browser, with no signup required on either end.
Completely. Because we use client-side state, your build choices, system configurations, budget allocations, and theme preferences never touch a remote server. Your data belongs entirely to your machine.
We support all modern web browsers leveraging standard web engines, including Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge across both desktop and mobile layouts.
The easiest way is to use a PC compatibility checker like ours. It automatically cross-references your selected CPU, motherboard socket, RAM generation (like DDR4 vs DDR5), case dimensions, and power supply wattage to ensure all parts fit and work together perfectly.
A bottleneck occurs when one component severely limits the performance of another (e.g., a high-end RTX 4090 GPU paired with an older budget CPU). You can avoid this by ensuring your CPU and GPU are balanced for your target resolution. Our engine highlights severe bottlenecks automatically.
No. DDR5 RAM has a completely different physical layout and pin configuration than DDR4. You must use DDR5 RAM with a DDR5 motherboard, and DDR4 RAM with a DDR4 motherboard. Our compatibility engine prevents you from mixing them up.
Your required wattage depends heavily on your CPU and Graphics Card. A good rule of thumb is to take your system's estimated total draw and add 20-30% headroom for stability and future upgrades. Our tool automatically calculates your real-time wattage requirements as you pick parts.
Yes! Case size determines motherboard compatibility (ATX, Micro-ATX, Mini-ITX), maximum graphics card length, and CPU cooler height clearance. You must check that your GPU and cooler will physically fit inside your chosen case.
Absolutely. There is no restriction on mixing CPU and GPU brands. An AMD Ryzen processor will work perfectly with an NVIDIA GeForce graphics card, and an Intel processor works flawlessly with an AMD Radeon GPU.
