Disclaimer
Last updated: 2026-07-07
Hardware Math is an independent website offering free PC-hardware calculators — power-supply (PSU) wattage sizing, monitor PPI and viewing-distance math, and GPU power-connector checks — alongside educational guides. This page explains what our tools can and cannot do, and the limits of what you should rely on them for.
In short: our results are planning estimates, not professional advice. They are a starting point to help you think through a build or purchase, not a substitute for the manufacturer's official specifications or the judgment of a qualified professional. Please read this page before acting on anything the site tells you.

Results Are Estimates for Planning Only
Every number Hardware Math produces — recommended PSU wattage, pixel density, viewing distance, connector counts, and so on — is an estimate generated from simplified models and sample data. It is intended to help you plan and compare options, nothing more.
Our calculators do not, and cannot, account for every variable in a real system. Factors such as component tolerances, ambient temperature, overclocking, transient power spikes, cable and adapter quality, firmware behavior, and how a specific unit performs in your specific case are outside what a general-purpose web calculator can model.
Treat our output as a rough guide. Give yourself sensible headroom, and confirm the details before you spend money or assemble hardware.
Not Professional Advice
The content and calculations on this site are provided for general informational and educational purposes only. They are not, and must not be relied upon as, professional advice of any kind.
Specifically, nothing here constitutes:
- Electrical advice — we are not electricians, and our estimates are not a substitute for proper electrical assessment, wiring, or safety inspection.
- Engineering advice — thermal, mechanical, or power-systems engineering decisions require qualified expertise we do not provide.
- Safety advice — building and operating PC hardware involves electricity and physical components; follow manufacturer safety instructions and consult a professional when in doubt.
- Legal or financial advice — purchase, warranty, and budgeting decisions are yours to make, ideally with appropriate professional input.
If your decision has safety, financial, or legal consequences, consult a suitably qualified professional. Do not treat this website as one.
Always Verify Against Official Manufacturer Specifications
Before you buy, build, or connect anything, verify every relevant detail against the official specifications published by the manufacturer of the actual part you are using.
This includes, but is not limited to: PSU rated and peak wattage, rail configuration and connector layout; GPU power-connector requirements and recommended system wattage; motherboard, case, and cooler compatibility and clearances; and monitor resolution and panel specifications. Manufacturer documentation for your exact model number is always the authoritative source — our figures are not.
Where our results and a manufacturer's official specification disagree, the manufacturer's specification is correct and ours should be disregarded.
No Guarantee of Accuracy or Outcomes
We build and maintain these tools in good faith, but we make no warranty or guarantee — express or implied — regarding the accuracy, completeness, reliability, or timeliness of any calculation, guide, or data on the site.
In particular, we do not guarantee:
- That any estimate is accurate or complete for your situation.
- That any two components identified as compatible will actually work together in your build.
- That a system built to our suggestions will be stable, perform as expected, or meet your needs.
- Any particular purchase outcome, price, availability, or satisfaction with hardware you buy.
You are responsible for your own build and buying decisions.
Hardware Data Is Best-Effort Sample Data
The hardware information behind our calculators is best-effort sample data compiled for illustration and planning. It may be incomplete, outdated, or contain errors, and it is flagged as needing verification.
Component specifications change, new models are released, and older entries may not reflect current products. Never assume a value in our data matches the part you intend to buy — check the manufacturer's current official specification for that specific model before relying on it.
Trademarks and No Brand Affiliation
Hardware Math is an independent website. We are not affiliated with, endorsed by, sponsored by, or otherwise connected to any hardware brand or manufacturer, including (for example) NVIDIA, AMD, Intel, Amazon, Corsair, Seasonic, or Cooler Master.
All product names, brand names, logos, and trademarks mentioned on this site are the property of their respective owners. They are used only for identification and descriptive purposes — to help you understand which kind of hardware a calculation or guide refers to — and their use does not imply any endorsement, partnership, or affiliation.
External Links
Some pages may link to third-party websites, such as manufacturer specification pages or reference material. These links are provided purely for your convenience.
We do not control third-party sites and are not responsible for their content, accuracy, availability, security, or privacy practices. Including a link does not imply that we endorse the linked site or anything on it. When you follow an external link, you leave Hardware Math and the terms and policies of that other site apply.
No Affiliate Links (and Future Policy)
As of the date at the top of this page, Hardware Math contains no affiliate links. We are not currently an Amazon Associate and are not a member of any affiliate or referral program, and we earn no commission from any purchase you make.
If we ever add affiliate links in the future, we will disclose that clearly and update this page and our related policies to say so. Until then, no such relationship exists, and any brand or product mention is purely for information.
A Note on How the Site Works
Hardware Math is a fully static website. Every calculation runs locally in your own browser. There is no backend server, no database, and no server-side processing, so the data you enter is not transmitted to us or stored anywhere off your device.
The site has no user accounts, no login, no contact form, and no analytics, advertising, or third-party trackers. It sets no cookies at all. The only client-side storage we use is your browser's localStorage, holding a single value — your light or dark theme preference — which stays on your device and is never sent anywhere.
Use at Your Own Risk and Limitation of Liability
You use Hardware Math and rely on its results at your own risk. Because our output consists of planning estimates that you are expected to verify against official manufacturer specifications, you remain solely responsible for your hardware choices, builds, and purchases.
To the extent permitted by applicable law, Hardware Math and its owner will not be liable for any loss or damage — including damage to hardware, cost of replacement parts, wasted purchases, downtime, or lost data — arising from your use of, or reliance on, this website, its calculators, its guides, or its data. This limitation reflects the fact that the site is free, static, and provided as a good-faith planning aid, and it does not seek to exclude any liability that cannot lawfully be excluded.
Governing law and jurisdiction for this disclaimer are [jurisdiction to be specified by the site owner].
Reporting a Data Error
We want the site to be as accurate as possible. If you spot a mistake in a calculation, a guide, or the hardware data, please tell us so we can review and correct it.
You can report errors by email at simon.agentinfra@gmail.com. Please include the page or tool involved, the specific value or statement you believe is wrong, and — if possible — a link to the manufacturer's official specification, so we can verify and fix it quickly.
Changes to This Disclaimer
We may update this disclaimer from time to time as the site evolves. When we do, we will revise the last-updated date shown at the top of the page. Your continued use of Hardware Math after a change means you accept the current version.
