TechFuel HQTechFuelHQ’s PC Builder parts dataset covers 126 components — CPUs, GPUs, motherboards, RAM, storage, PSUs, and cases — with verified specifications, compatibility fields, and per-row source pages. Street prices were removed on 2026-08-01 for Amazon Associates policy compliance; specs and compatibility data are unaffected. Open CC BY 4.0 data.

What this is — the PC Builder parts dataset, verified and honestly dated
- 126 parts, 7 categories — CPU, GPU, motherboard, RAM, storage, PSU, case — with the specification and compatibility fields the PC Builder runs on.
- Every row added in the 2026-07-29 expansion cites its source — the manufacturer, Newegg, or B&H specification page its specs were read from.
- Prices were removed on 2026-08-01. They were Amazon-observed street prices, and our Amazon Associates participation means Amazon price data only appears through Amazon's approved mechanisms. The change log below has the full story.
- Open data (CC BY 4.0). Fork it, remix it, build on it — attribution required.
The short version
This page is the canonical home of the TechFuelHQ PC Builder parts dataset — 126 off-the-shelf components with verified specifications and the compatibility fields that make a build checker possible: socket, supported chipsets, RAM type, TDP, GPU length, PSU wattage, case clearance. The interactive PC Builder is built directly on this file and does the compatibility math for you.
The dataset’s founding rule is freshness honesty: every row carries the date it was last verified, and a date only moves when the row is actually re-confirmed. Numbers we cannot stand behind do not ship — rows have been retired under that rule, and on 2026-08-01 the same rule retired an entire field. The details are below, stated plainly, because a dataset that documents its own corrections is worth more than one that pretends it never needed any.
Why the prices left, in plain language
Until 2026-08-01 this dataset also carried street prices. The 97 rows added in the 2026-07-29 expansion each recorded a price observed on Amazon.com, attributed to the exact listing it was read from. That attribution was the honest way to publish an observed number — and it is also what made the arrangement untenable: TechFuelHQ participates in the Amazon Associates program, and the program’s policies only permit showing Amazon price data through Amazon’s own mechanisms, which keep displayed prices current. A dated public snapshot, openly licensed for reuse, is not that.
So the price fields came out — price_usd, price_source, and price_asin on all 97 expansion rows. The 29 pre-expansion rows went through the same review the same day, and the same reading reached them: their original methodology note lists Amazon among the retailer sources, and without per-row attribution there is no way to clear any individual figure as non-Amazon. Their prices came out too. The dataset now carries no prices at all — and nothing else changed: the specifications, the compatibility fields, and the per-row source specification pages are exactly as verified.
Re-pricing from sources that carry no such restrictions — manufacturer MSRPs, other retailers — is planned. When prices return, they will return with the same per-row provenance discipline the specs already have.
What the dataset covers
| Category | Parts | Spec highlights |
|---|---|---|
| CPU | 30 | cores, threads, boost clock, TDP, socket, supported chipsets |
| GPU | 25 | VRAM, board power, length, recommended PSU |
| Motherboard | 16 | socket, chipset, RAM type, form factor |
| RAM (DDR5) | 13 | capacity, speed, timings, rank |
| Storage (SSD) | 15 | interface, rated speeds, endurance |
| Power supply | 12 | wattage, efficiency rating, connectors |
| Case | 15 | form factor, max GPU length |
97 of the 126 rows were verified on 2026-07-29; 23 carry 2026-07-24 and 6 carry 2026-06-09, kept because their exact SKU could not be re-confirmed on the later pass. Each row’s last_verified field tells you which is which.
How verification works
Verification is a deliberate pass, not a scrape. In the 2026-07-29 expansion, any candidate part whose specifications could not be confirmed against a page that actually loaded was dropped rather than estimated — 41 candidates went that way, including every part from several vendors whose sites refuse automated retrieval. That constraint is visible in the data: NVIDIA add-in-board rows skew toward ASUS because it was the one board partner whose specification pages could be read. PCIe lane counts appear only where a retrieved page stated them explicitly.
One row was retired in the same pass: a DDR5-7200 kit whose stored figure had drifted far from anything observable in the market. Rather than leave a number we could not stand behind in an openly licensed dataset, the row came out. The 2026-08-01 price removal is that same rule applied at field scale.
Where the specs come from
Some links below are affiliate links; if you buy through them TechFuel HQ may earn a small commission at no extra cost to you. Commissions never influence which products get recommended — see our disclosure.
Expansion rows (2026-07-29) cite the manufacturer, Newegg, or B&H specification page each was read from, in the row’s source field. Pre-expansion rows were compiled from manufacturer pages, TechPowerUp, Tom’s Hardware, and verified retailer listings. Performance-tier labels are TechFuelHQ editorial assessments based on aggregate review consensus — except where a part appears in a TechFuelHQ open bench dataset, in which case its tier is anchored to first-party measurements. Treat them as rough tiering, not head-to-head benchmark claims.

The raw JSON carries the per-row last_verified dates and the full methodology note in _meta, so downstream projects can key off both directly.
The same JSON is mirrored on Kaggle for dataset discovery. The canonical file served here is version 2.1.0 and contains no price fields; this page owns the correction history and current compatibility contract.
Change log
- 2026-08-01 — v2.1.0. Prices removed from the 29 pre-expansion rows after the same policy review: their original methodology note lists Amazon among the retailer sources and no per-row attribution exists to separate the figures. The dataset is now entirely price-free. Three dollar-band part notes retiered to plain tier language.
- 2026-08-01 — v2.0.0. Price fields (
price_usd,price_source,price_asin) removed from the 97 expansion rows for Amazon Associates program-policy compliance; three part notes that referenced observed prices rewritten. Specs, compatibility fields, and source pages unchanged. Re-pricing from non-restricted sources planned. - 2026-07-29 — v1.2.0. Expansion from 30 parts to 126; per-row
sourceprovenance introduced; one stale row retired; 41 unconfirmable candidates dropped rather than estimated. - 2026-07-24 — v1.0. Initial public release, 30 parts.
The dataset version at each change is recorded in the raw JSON’s _meta, and dataset_version above always matches the file being served.
