Prebuilt vs. Building Your Own PC in 2026: Which Is Cheaper?

For years the rule was simple: build it yourself and save money. The 2025–2026 memory shortage broke that rule. Large builders like Dell, MSI and Skytech locked in RAM and SSD supply before prices jumped, so for a stretch their finished systems cost less than buying the same parts at retail.

What the comparisons showed

In December 2025 Tom's Guide priced several popular prebuilts against matching parts lists. RTX 5050, 5060 Ti, RX 9070 XT and RTX 5070 Ti systems all came in cheaper than DIY, in some cases by $200 or more, and the DIY totals often didn't even include a case or power supply. Builders have since raised some prices, so the gap now changes model to model.

When a prebuilt makes sense

• Your budget is under about $1,500 and you want a current GPU.
• The listing names the exact CPU, GPU, RAM amount and SSD size (not just "RTX graphics").
• It comes with at least 16GB (ideally 32GB) of dual-channel RAM and a 1TB NVMe SSD.

When DIY still wins

• You're reusing parts: a case, PSU, SSD or RAM from your old PC.
• You want a specific high-end part (a 9800X3D, a quiet case, a quality PSU) that prebuilts skimp on.
• You plan to upgrade often. DIY boards and PSUs are usually more upgrade-friendly.

Prebuilt red flags

• Unnamed power supply brand or wattage.
• Single-stick RAM (halves memory bandwidth).
• Proprietary motherboard or case that blocks future upgrades.
• No airflow: solid glass front with one fan.

Price it both ways: build the same spec in the PC Atlas Wizard, then compare that total to the prebuilt.
