PC Builder — Build a Custom PC for Your Budget
Tell us your budget and what you'll use it for — gaming resolution and refresh, AI/ML, content creation, or general — and our AI assembles a complete, compatible PC from real catalog parts, each linked to its Amazon or eBay listing, with estimated FPS and a shareable link. Free, no sign-up.
Prefer a finished parts list? The Reddit-consensus 2026 gaming PC builds (1080p, 1440p, high-refresh 1440p and 4K) and the 2026 build-your-own gaming PC guide price every part and put the whole build in one Amazon cart.
Building for local AI? What r/LocalLLaMA and r/buildapc concluded, with every thread linked: a 16GB-card local-LLM build · used RTX 3090 (24GB) vs a new GPU · what runs on an RTX 3060 12GB · gpt-oss on a 12GB GPU.
How it works
- Set a budget and pick a use case (gaming, AI workstation, creator, general).
- For gaming, choose your target resolution, refresh rate, and games.
- Get a complete build — CPU, GPU, motherboard, RAM, storage, PSU, case, cooler — every part checked for socket, memory, and power compatibility.
- Buy the parts on Amazon or eBay, swap any component, and share your build.

Frequently asked questions
- Is the SpecPicks PC Builder free?
- Yes — it is completely free with no sign-up. Set a budget and a use case and you get a complete, compatible parts list with each part linked to its Amazon or eBay listing, plus a shareable link.
- How does the PC Builder choose parts?
- It assembles a complete build from real catalog parts matched to your budget and use case, then checks CPU socket, RAM generation, and PSU wattage so every part is compatible. Prices come from stored listing data, never fabricated.
- Can it build a gaming PC for 1080p, 1440p, or 4K?
- Yes. Pick your target resolution and refresh-rate and the builder sizes the GPU and CPU accordingly and shows estimated FPS for popular games from public benchmarks.
- Can it build an AI or LLM workstation?
- Yes. Choose the local models you want to run (such as Llama, Qwen, or DeepSeek) and the builder sizes GPU VRAM to fit the largest one and estimates tokens-per-second throughput.
- Are the prices real and up to date?
- Prices come from Amazon and eBay listing data that is refreshed on a rolling schedule, so they may have changed — each part links to its listing, where the current price is set. The builder never shows an invented price; a part not in our catalog yet links to a live search instead.
- Can I share, tweak, or save a build?
- Yes. Every build gets a shareable link you can reopen on any device, swap any component in, or save as a new build — no account required.
