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

A budget PC for web browsing, email, and video streaming costs $400 to $600. A gaming machine that runs current titles at high settings costs $1,200 to $1,800. A workstation for video editing, 3D rendering, or software development costs $2,000 to $4,000 or beyond. The price difference comes down to the processor, graphics card, and storage — the three parts that determine what your PC can actually do.

You are not paying for a brand name or a factory warranty. You are paying for parts: a CPU, a motherboard, RAM, a power supply, a case, storage, and (usually) a graphics card. Each part has a real cost, and that cost changes based on what the part does. A processor that handles gaming costs three to five times more than one that handles email.

The total also depends on what you already own. If you have a monitor, keyboard, and mouse, you only buy the tower. If you are starting from nothing, add $150 to $300 for those peripherals. If you need Windows, add $100 to $140 for a license.

Key Takeaways

  • A basic PC for everyday tasks costs $400 to $600; a gaming PC costs $1,200 to $1,800; a workstation for professional work costs $2,000 and up.
  • The processor and graphics card account for 40 to 60 percent of the total cost and determine what the PC can do.
  • You will spend $50 to $150 on the power supply, $50 to $100 on the case, and $80 to $200 on storage, depending on speed and capacity.
  • If you do not already own a monitor, keyboard, and mouse, add $150 to $300 for those items.
  • Windows licenses cost $100 to $140; Linux and some other operating systems are free.

Budget PC: $400 to $600

A budget PC handles email, web browsing, video streaming, and document editing without lag. It will not run new games or edit video. The processor is usually an AMD Ryzen 5 or Intel Core i5 from the current or previous generation, costing $120 to $180. The motherboard costs $80 to $120. RAM is 16 gigabytes and costs $40 to $60. Storage is a 512-gigabyte solid-state drive (SSD) and costs $40 to $60.

You do not need a dedicated graphics card for this build. The processor has built-in graphics that handle everyday tasks. The power supply costs $50 to $80. The case costs $40 to $70. Total: $410 to $590 before monitor, keyboard, mouse, and Windows.

This machine will last four to six years for everyday use. The bottleneck is usually the storage — a 512 GB drive fills up fast if you keep photos or video files. Plan to add an external hard drive ($60 to $100) or upgrade the internal drive later.

Gaming PC: $1,200 to $1,800

A gaming PC runs current games at high or ultra settings, 60 frames per second or higher, at 1440p resolution (the standard for gaming monitors). The processor is an AMD Ryzen 7 or Intel Core i7, costing $300 to $450. The graphics card is the biggest expense: an NVIDIA RTX 4070 or AMD equivalent costs $500 to $700. These two parts alone account for $800 to $1,150 of the total.

RAM is 32 gigabytes and costs $80 to $120. Storage is a 1-terabyte SSD and costs $80 to $120. The motherboard costs $150 to $250. The power supply must be robust — 750 watts or higher — and costs $100 to $150. The case costs $80 to $150. Total: $1,190 to $1,840 before monitor, keyboard, mouse, and Windows.

A gaming monitor (1440p, 144 Hz or higher) costs $250 to $400. If you do not have one, add that to the total. This machine will handle games released over the next three to four years without major upgrades. After that, the graphics card will need replacement to stay current.

Workstation PC: $2,000 to $4,000 and up

A workstation handles video editing, 3D rendering, software compilation, or data analysis — tasks that demand fast processors, large amounts of RAM, and fast storage. The processor is a high-core-count chip: an AMD Ryzen 9 or Intel Core i9, costing $500 to $800. RAM is 64 gigabytes or more and costs $200 to $400. Storage is a 2-terabyte or larger SSD and costs $150 to $300.

A dedicated graphics card is often necessary. For rendering and design work, an NVIDIA RTX 4080 or higher costs $1,000 to $1,500. For video editing, a mid-range card like an RTX 4070 ($500 to $700) is often enough. The motherboard costs $200 to $350. The power supply must handle sustained high load — 850 watts or higher — and costs $150 to $250. The case costs $100 to $200. Total: $2,200 to $4,000 before monitor and peripherals.

A professional monitor (color-accurate, high resolution) costs $400 to $1,000 or more. This machine will remain useful for five to seven years because the processor and RAM are the main drivers of performance, and both age more slowly than graphics cards.

What each part costs and why

Processor (CPU): $120 to $800. Entry-level chips handle everyday tasks. Mid-range chips ($300 to $450) handle gaming and light creative work. High-end chips ($500 to $800) handle rendering, compilation, and heavy multitasking. The cost reflects the number of cores, clock speed, and power efficiency.

Graphics card (GPU): $0 to $1,500. Budget and workstation builds often skip this — the processor has built-in graphics. Gaming and professional rendering demand a dedicated card. Entry-level cards ($150 to $300) handle older games. Mid-range cards ($400 to $700) handle current games at high settings. High-end cards ($800 to $1,500) handle new games at maximum settings or professional rendering.

Motherboard: $80 to $350. The motherboard connects all the parts. A cheap board ($80 to $120) works fine for budget builds. A mid-range board ($150 to $250) offers more features and better power delivery for gaming. An expensive board ($250 to $350) is built for overclocking or professional work.

RAM (memory): $40 to $400. 16 gigabytes is standard for gaming and everyday use. 32 gigabytes is standard for gaming at very high settings and light creative work. 64 gigabytes or more is for professional rendering and data work. The cost per gigabyte is roughly $2 to $4.

Storage (SSD): $40 to $300. A 512 GB drive costs $40 to $60 and is tight for a gaming machine. A 1 TB drive costs $80 to $120 and is standard. A 2 TB drive costs $150 to $250. Faster drives (NVMe M.2) cost more than slower ones (SATA), but the speed difference matters mainly for large file transfers and game loading times.

Power supply: $50 to $250. A 550-watt supply costs $50 to $80 and is enough for budget and gaming builds. A 750-watt supply costs $100 to $150 and is standard for high-end gaming. A 1000-watt supply costs $200 to $250 and is for extreme gaming or workstations. The cost reflects efficiency rating (80+ Bronze, Gold, Platinum) and brand reputation.

Case: $40 to $200. A cheap case ($40 to $70) works but has poor airflow and cable management. A mid-range case ($80 to $150) balances cost and usability. An expensive case ($150 to $200) offers excellent airflow, cable management, and build quality.

Monitor: $100 to $1,000. A basic 1080p monitor costs $100 to $150. A 1440p gaming monitor costs $250 to $400. A 4K monitor costs $400 to $800. A professional color-accurate monitor costs $600 to $1,500.

Keyboard and mouse: $30 to $200. A basic keyboard and mouse cost $30 to $50. A gaming keyboard and mouse cost $80 to $150. A mechanical keyboard alone can cost $100 to $200.

Ways to spend less

Buy last-generation parts. A processor or graphics card from two years ago costs 30 to 50 percent less than the current model and still handles most tasks. The performance difference is small for everyday use and gaming.

Skip the dedicated graphics card if you do not game. Built-in graphics are free and sufficient for web browsing, video, and document work. This saves $150 to $1,500 depending on what card you would have bought.

Buy a smaller SSD and add storage later. A 512 GB drive costs $40 to $60. You can add a second drive ($80 to $150) in a year or two when you need the space. This spreads the cost over time.

Use Linux or a free operating system instead of Windows. Linux is free and runs on any PC. Windows costs $100 to $140. This is a one-time savings but a real one.

Buy a used graphics card from a reputable seller. Graphics cards hold their value reasonably well, and a used card from two years ago costs 40 to 60 percent less than new. Check the return policy and warranty before buying.

Ways to spend more

Buy the newest parts. A processor or graphics card released within the last three months costs 10 to 30 percent more than the same part three months later. The performance gain is usually small.

Buy premium brands. ASUS, Corsair, and Noctua charge more for the same performance because of build quality and customer service. The difference is real but not always worth the cost.

Buy fast storage. An NVMe SSD costs 20 to 40 percent more than a SATA SSD but is noticeably faster only for large file transfers and game loading. For everyday use, the difference is invisible.

Buy RGB lighting and tempered glass. These features add $50 to $150 to the case cost and do nothing for performance. They are purely aesthetic.

Buy a high-refresh-rate monitor. A 240 Hz monitor costs $300 to $600 and is useful only for competitive gaming. A 144 Hz monitor costs $250 to $400 and is the standard for gaming. A 60 Hz monitor costs $100 to $200 and is fine for everything else.

Frequently Asked Questions

Can I build a PC for under $400?

Yes, but it will be very slow. A $300 to $400 PC can handle email and web browsing but will struggle with video streaming and multitasking. You would be better off buying a used office PC ($150 to $250) and upgrading the storage and RAM later. The used route often costs less and performs better.

Is it cheaper to buy a prebuilt PC or build one myself?

Building is usually cheaper by $100 to $300 because you avoid the manufacturer's markup and labor cost. However, prebuilts come with a warranty and support. If you are not comfortable troubleshooting hardware, a prebuilt is worth the extra cost. If you are willing to learn, building saves money and teaches you how your machine works.

How much should I spend on a monitor?

Spend what matches your PC. A $500 gaming PC paired with a $400 monitor is unbalanced. A $1,500 gaming PC paired with a $150 monitor is also unbalanced. A good rule is to spend 15 to 25 percent of your PC budget on the monitor. For a $1,500 PC, that is $225 to $375.

Will my PC cost more to run than a laptop?

A PC uses more electricity than a laptop — roughly $10 to $20 per month depending on usage and local electricity rates. A laptop uses $2 to $5 per month. Over five years, the difference is $600 to $1,200. This is a real cost but usually worth it for gaming or professional work, where a PC outperforms a laptop by a large margin.

Do I need to upgrade my PC after a few years?

For everyday use, no. A budget PC from five years ago still handles email and web browsing. For gaming, yes — after three to four years, new games will run slowly on the graphics card. You can upgrade just the graphics card ($300 to $700) instead of building a new PC. For professional work, upgrades depend on the software and the tasks.
