Build a Cheap Gaming PC: 8 Budget Parts (2025)

Building a capable gaming PC doesn't have to drain your wallet — a well-planned budget build under $700 can handle modern titles at 1080p without compromise. Per Gamers Nexus, a smart component selection in early 2026 can deliver strong 1080p gaming performance for well under $700 when you prioritize GPU and CPU value. Whether you're a first-time builder or upgrading an aging rig, knowing which parts give you the most frames per dollar is everything.

Build a Cheap Gaming PC: 8 Budget Parts (2025)

Below you'll find detailed information about each aspect, including important details and considerations.

1. CPU

The CPU is one of the most critical budget decisions when building a cheap gaming PC, since overspending here can blow your entire component budget. For budget builds, AMD's Ryzen 5 5600 (around $100–$120) or Intel's Core i3-12100F (around $80–$100) deliver solid gaming performance without breaking the bank. Either handles modern titles at 1080p without bottlenecking a mid-range GPU.

Budget picks:

• AMD Ryzen 5 5600 – ~$100–$120, 6 cores, excellent price-to-performance
• Intel Core i3-12100F – ~$80–$100, strong single-core speeds for gaming
• Avoid overspending on 12+ core CPUs — gaming rarely uses more than 6–8 cores

2. Motherboard

Choosing a compatible, no-frills motherboard keeps costs down in a budget gaming build without sacrificing stability. Match the board to your CPU socket — B550 for AMD Ryzen 5000 series or B660/H670 for Intel 12th/13th gen — and skip premium features like overclocking support you won't use. Expect to spend $70–$120 on a reliable entry-level board.

What to look for:

• B550 (AMD) or B660 (Intel) chipsets offer the best budget value
• Ensure at least 2 RAM slots and 1 M.2 slot for future storage upgrades
• Avoid X570/Z690 boards — overkill cost for a budget build

3. GPU

The GPU is the single most important component for gaming performance, making it the part worth allocating the largest share of your budget toward. For a cheap gaming PC targeting 1080p, the AMD RX 6600 (around $150–$180 used or refurbished) or Nvidia RTX 3060 (around $200–$230) offer strong frame rates in most modern titles. According to Gamers Nexus, prioritizing GPU spend over other components is the key principle in any budget gaming build.

Top budget GPU options:

• AMD RX 6600 – ~$150–$180, excellent 1080p performance per dollar
• Nvidia RTX 3060 – ~$200–$230, adds ray tracing and DLSS support
• Check used GPU markets (eBay, Facebook Marketplace) for 20–30% savings

4. RAM

RAM is one of the easiest places to save money when putting together a budget gaming rig without sacrificing real-world performance. For most games in 2025, 16GB DDR4 is the sweet spot — it handles modern titles comfortably while keeping costs low. Spending beyond that is unnecessary unless you're streaming or running heavy background apps simultaneously.

What to look for:

• 16GB DDR4-3200 kits typically cost $25–$40 (two 8GB sticks for dual-channel)
• Dual-channel configuration improves performance over a single stick at no extra cost
• Match RAM speed to your motherboard's supported spec to avoid paying for unused headroom

5. Storage

Choosing the right storage is critical for keeping your cheap PC build fast and functional without blowing the budget on overkill drives. A 500GB–1TB SATA SSD dramatically improves boot times and game load speeds compared to an HDD and costs as little as $30–$55. NVMe SSDs offer faster transfer speeds but the price premium rarely justifies itself in a budget build focused on gaming.

Budget storage options:

• 500GB SATA SSD: ~$30–$40 (Kingston A400, Crucial BX500)
• 1TB SATA SSD: ~$50–$60 — best value for most budget builders
• Avoid spinning HDDs as your primary drive — load times hurt the overall experience

6. Case

The case is one area where budget builders can cut costs without any performance penalty whatsoever — airflow and fit matter far more than aesthetics. A mid-tower ATX or Micro-ATX case in the $30–$60 range provides adequate ventilation, cable management options, and room for standard components. Verify it supports your motherboard form factor and has enough clearance for your GPU length before purchasing.

Key considerations:

• Popular budget picks: Fractal Focus G (~$50), Cooler Master Q300L (~$40)
• Prioritize cases with at least one pre-installed fan to cut additional cooling costs

7. Power Supply

Choosing the right PSU is one of the most budget-sensitive decisions in a cheap gaming PC build — an underpowered or inefficient unit can damage components or force costly upgrades later. For a budget build using a mid-range GPU and CPU like the Ryzen 5 5500, a 550W–650W 80+ Bronze certified unit typically covers everything without overspending.

What to look for:

• 550W–650W capacity handles most budget GPU + CPU combos
• 80+ Bronze rating balances efficiency and cost (~$40–$65)
• Semi-modular designs reduce cable clutter in smaller cases

8. Operating System

Windows 11 Home is the standard OS for gaming PCs, but at ~$139 retail it can strain a tight parts budget. Many builders legally reduce this cost by purchasing OEM licenses (~$20–$30 from authorized resellers) or temporarily using Windows without activation until they can afford a key.

Cost-saving options:

• OEM Windows 11 Home keys: ~$20–$30 online
• Retail boxed copy: ~$139 (not recommended for budget builds)
• Linux (free) works for some games via Steam's Proton layer

Final Words

From sub-$300 starter rigs to capable $600 mid-range machines, building a cheap gaming PC has never been more achievable. Save even more by buying used PC parts to stretch your budget further without sacrificing performance.
