PC building costs range from $400 to $3,000 depending on what you want to do

A working PC costs between $400 and $600 if you browse the web, watch video, and use documents. A PC for gaming or video editing runs $1,000 to $1,500. High-end gaming or professional work can reach $2,000 to $3,000 or more. The price depends almost entirely on the processor and graphics card you choose — those two parts often account for half your total budget. Everything else (motherboard, RAM, storage, power supply, case) scales with them but costs far less individually.

Your actual cost also depends on what you already own. If you have a monitor, keyboard, and mouse, you only budget for the tower itself. If you need those too, add $150 to $400. Used parts can cut costs by 20 to 40 percent, but carry the risk that they may fail sooner or lack a warranty.

Key Takeaways

  • Budget $400 to $600 for basic web browsing and documents, $1,000 to $1,500 for gaming, and $1,500 to $3,000 for video editing or professional work.
  • The processor and graphics card together usually cost 40 to 60 percent of your total budget; everything else scales down from there.
  • You will need a monitor, keyboard, and mouse separately unless you already own them — add $150 to $400 if you do not.
  • Buying used parts can lower your cost by 20 to 40 percent but means no manufacturer warranty and a higher chance of failure.

Budget breakdown for a basic browsing and documents PC

A PC for email, web browsing, spreadsheets, and video streaming costs $400 to $600 for the tower. You need a processor like an Intel Core i3 or AMD Ryzen 5 (around $100 to $150), 16 GB of RAM ($40 to $60), a 512 GB solid-state drive ($40 to $60), a motherboard ($80 to $120), a 500-watt power supply ($50 to $80), and a case ($50 to $100). You do not need a dedicated graphics card because the processor has one built in.

This setup handles multiple browser tabs, video calls, and streaming without lag. It will not play new games smoothly or edit video quickly, but it does what most people do every day. The parts are widely available and have long track records, so failures are uncommon.

Budget breakdown for a gaming PC

A PC that plays current games at good frame rates costs $1,000 to $1,500. The processor (Intel Core i5 or AMD Ryzen 5) runs $200 to $300. The graphics card — the most expensive single part — costs $300 to $600 depending on how new it is and how demanding the games are. Add 16 GB of RAM ($50 to $80), a 1 TB solid-state drive ($70 to $100), a motherboard ($120 to $180), a 650-watt power supply ($80 to $120), and a case ($80 to $150).

At this price point you can play games like Baldur's Gate 3, Starfield, and Cyberpunk 2077 at medium to high settings with 60 frames per second on a 1440p monitor. If you want higher frame rates or maximum settings, add $300 to $500 more for a better graphics card. If you play older or less demanding games (Valorant, League of Legends, Minecraft), you can drop to $700 to $900.

Budget breakdown for video editing and professional work

A PC for video editing, 3D rendering, or software development costs $1,500 to $3,000. You need a faster processor like an Intel Core i7 or AMD Ryzen 7 ($350 to $500), 32 GB of RAM ($100 to $150), a 2 TB solid-state drive ($150 to $250), and often a dedicated graphics card ($300 to $800) depending on the software. Add a motherboard ($150 to $250), a 750-watt power supply ($100 to $150), and a case ($100 to $200).

The extra RAM and storage matter because video files are large and editing software uses a lot of memory at once. A faster processor cuts the time your computer spends rendering. If you work with 4K video or complex 3D models, budget toward the higher end or beyond. If you edit mostly 1080p video or do light coding, $1,500 to $1,800 is usually enough.

Where the money actually goes

The processor and graphics card together typically cost 40 to 60 percent of your budget. In a $1,000 gaming PC, those two parts might cost $500 to $700 combined. Everything else — RAM, storage, motherboard, power supply, case — scales down from there. This is why upgrading a PC later usually means replacing the processor or graphics card, not the smaller parts.

The power supply and case are the parts people most often underspend on, then regret. A cheap power supply can fail and damage other parts. A cheap case makes building harder and leaves less room for cooling. Spending an extra $30 to $50 on each is worth it. RAM and storage are the easiest to upgrade later, so if you are tight on budget, start with less and add more in a year or two.

How used parts change the cost

Buying used graphics cards and processors can cut your total cost by 20 to 40 percent. A graphics card that costs $400 new might cost $250 to $300 used. A processor that costs $300 new might cost $200 to $250 used. Used RAM and storage are less common but also cheaper when available.

The trade-off is that used parts have no manufacturer warranty and may fail sooner. A used graphics card might have been mined with (run continuously at high load), which shortens its life. Used processors are usually safe because they rarely fail, but used power supplies are risky because failure can damage everything connected to them. Buy used parts from sellers with return policies if possible, and avoid used power supplies unless you know the seller well.

What you need to buy separately

The tower itself is only part of the cost. You also need a monitor ($150 to $400 depending on size and refresh rate), a keyboard ($30 to $150), and a mouse ($20 to $80). If you already own these, you can skip them. If you do not, budget an extra $200 to $400 on top of the tower cost.

You may also want speakers or headphones ($30 to $200), a desk and chair (highly variable), and cables or adapters. Most of these are optional or can be added later. The monitor is the one thing you need right away to use the PC at all.

Frequently Asked Questions

Can I build a PC for under $400?

Yes, but it will be very basic. You can find used parts or older new stock for $300 to $400 total, but the processor and graphics will be several years old. It will handle web browsing and documents but not games or video editing. New parts at that price are hard to find because manufacturers do not make low-end components anymore.

How much more does a PC cost than a laptop?

A PC with the same performance as a laptop usually costs $100 to $300 less because you are not paying for a screen, keyboard, or battery. A $1,200 gaming laptop might match a $900 gaming PC. However, you need to buy a monitor separately, which narrows the gap. A laptop is cheaper if you already have a monitor and keyboard you can plug into.

Do I need to spend more if I want the PC to last longer?

Not necessarily. A $600 PC from five years ago still works fine for browsing and documents. A $1,200 gaming PC from five years ago still plays games, though at lower settings than it did when new. Spending more gets you better performance now, not longer lifespan. The parts that fail first (power supply, fans) cost the same whether your PC is $500 or $2,000.

What if I want to upgrade later instead of buying everything now?

Start with a $600 to $800 PC and add a graphics card later when you have more money. Or start with 16 GB of RAM and add another 16 GB in a year. Storage and RAM are the easiest to upgrade. Upgrading the processor or motherboard later means replacing more parts, so if gaming is your goal, buy a decent graphics card from the start.

Are there hidden costs I should know about?

No major ones. You might spend $10 to $30 on thermal paste, cable ties, or adapters during building, but these are small. Windows 11 costs $120 if you do not already own a license, though you can use it free with a watermark for as long as you want. Antivirus software is free (Windows Defender is built in). The main costs are the parts themselves and the peripherals.
