Our calculators are educational planning aids. They are not substitutes for measurement, product specifications or professional advice.
CPU and GPU estimates
Hardware categories and compatibility guidance are approximate. Our site does not inspect your computer, run a benchmark, test exact games or guarantee a frame rate. Bottlenecks vary with resolution, settings, game engine, thermal behavior and background workloads.
Power supply estimates
PSU results rely on the values you provide plus your selected headroom. They do not verify transient power spikes, connector standards, overclocking, PSU quality, future upgrades or manufacturer minimum recommendations. Always check official device guidance and safe installation instructions.
Electricity estimates
Energy cost results use watts × operating hours ÷ 1000 × price per kilowatt-hour. They do not automatically account for variable load, power factors, tiered utility pricing, fixed fees or taxes. Actual bills may differ.
External information
Third-party product references, prices, benchmarks and linked websites may change. We cannot guarantee that external information remains current, accurate or suitable for your use.
Limitation of responsibility
Use tools at your own discretion. To the extent permitted by applicable law, we do not accept liability for losses arising from reliance on estimates or purchase decisions based solely on this website.
