Build a PC in 2026
From free DIY planners to full custom-built powerhouses with RTX 5090s — here’s every site worth knowing this year.
Building a PC in 2026 is both more exciting and more complicated than ever. GPU prices are still volatile thanks to the AI-driven hardware crunch, RTX 5000-series cards from Nvidia have launched at steep MSRPs, and AMD’s Ryzen 9000 lineup is offering stiff competition at the CPU level. All of this makes choosing the right parts at the right price more critical than it’s ever been.
Whether you’re planning every component yourself or want someone else to handle the hard work, the websites below cover every approach — from free planning tools like PCPartPicker, to boutique builders like Xidax who’ll hand-build a machine with a lifetime warranty. We’ve updated every price, spec, and feature to reflect what’s actually available right now in 2026.
🛠️ FREE DIY PLANNING TOOLS
Still the gold standard for DIY PC builders in 2026. PCPartPicker lets you select every component from a massive database, automatically checks compatibility between parts, alerts you to conflicts, and compares live prices across retailers including Amazon, Newegg, and B&H. It also features a huge community of shared builds for inspiration, complete with user reviews and benchmarks.
- Real-time price tracking across all major stores
- Automatic compatibility warnings
- Huge community build library
- Wattage estimator included
- Doesn’t sell or build anything itself
- Requires you to know what you want
Newegg’s built-in PC builder tool combines part selection and purchasing in one place. Unlike PCPartPicker, everything you choose can go straight to your Newegg cart. It checks compatibility, offers bundle deals, and frequently has flash sales on GPUs and CPUs. A great option if you prefer buying everything from a single storefront rather than hunting across multiple retailers.
- Buy parts directly — no third-party redirects
- Frequent GPU/CPU flash sales
- Large in-stock component selection
- Prices don’t always beat Amazon
- Customer service can be hit or miss
🏭 CUSTOM PC BUILDER WEBSITES
NZXT’s BLD service walks you through a step-by-step questionnaire — you tell it your budget, the games you play, and your performance targets, and it recommends the best build for your needs. It’s one of the most beginner-friendly custom builder experiences available, with a clean minimalist aesthetic, RTX 5000-series GPU options, and quick turnaround times. They also launched a FLEX subscription rental model if you’d rather not pay upfront.

One of the oldest names in the custom PC game, iBUYPOWER has been building gaming rigs since 1999. Their Easy Builder tool lets you filter by processor type (Intel or AMD), price, storage, and GPU tier, and they offer both ready-to-ship RDY Prebuilts and fully custom configurations. In 2026 they’re bundling select RTX 50-series builds with free copies of Resident Evil Requiem and Crimson Desert — solid value-adds for gamers.
- Most affordable entry point on this list
- Ships in ~5 business days
- Wide GPU/CPU selection including RTX 5070
- Game bundles with select builds
- Budget builds use cheaper PSUs/motherboards
- Short 1-year warranty vs. competitors
Xidax has grown into one of the most reputable custom PC builders thanks largely to high-profile sponsorships (MrBeast, Unbox Therapy) and one standout feature: a lifetime limited warranty on parts and labor for all desktops. In 2026 they’re offering RTX 5090 configs from $4,200, RTX 5080 and 5070 Ti options, and extras like custom laser etching, powder coating, GPU water blocks, and Affirm financing from $66/month.
