About TweakGearPro
Free, client-side PC build & hardware calculators — built to be used, not just read.
Who runs TweakGearPro
TweakGearPro is an independent editorial research project run by The TweakGearPro Editorial Team. We are not affiliated with, endorsed by, or sponsored by any hardware vendor, retailer, or testing lab — and we do not sell hardware. The team is responsible for every page, figure, and calculator on this site.
Our approach
Data is compiled from official manufacturer datasheets, board-power specifications, and published benchmark sources, with retrieval dates on every page. Every figure is verified against a source before it is published; anything unverified is marked as pending or omitted entirely. The open dataset is refreshed annually with a versioned changelog.
Why a calculator toolkit
Search engines now answer a lot of “what is X” hardware questions directly in AI Overviews. A static article about PSU sizing gets zero clicks because the answer is already on the results page. A calculator is different: an overview can describe the formula, but it cannot run it against your exact parts. So TweakGearPro is pure interactive tools — you click to get your number.
How the estimates work
Every calculator runs entirely in your browser (client-side JavaScript). There is no backend, no account, and no data leaves your device. The math uses typical manufacturer board-power and spec values, plus simple rules of thumb (headroom percentages, TDP vs cooler ratings, VRAM by workload). They are planning aids, not purchase guarantees.
Independence
TweakGearPro is not affiliated with, endorsed by, or operated by any hardware vendor — NVIDIA, AMD, Intel, ASUS, Corsair, or others. Brand and model names appear only as common references. Always verify figures against the official datasheet for the exact part you plan to buy or build with.
Calculators
PSU Wattage, Power Draw, Thermal Headroom, Bottleneck Estimator, GPU VRAM, Build Cost (TCO), Monitor Hz → FPS, and Unit Converter.
What we are not
We are not a hardware vendor, a retailer, a testing lab, an overclocking service, or a licensed professional advisor. Where a product or service helps, we point to reputable third-party providers, but we hold no special endorsement from them and our recommendations are never paid for. Specifications change — always verify with the official datasheet before buying or building.
