Using the U.S. Energy Information Administration’s 2025 residential average of 17.30¢/kWh, a computer drawing an average of 10 W would cost about $15.15 a year to run; at 20 W, about $30.31; and at 35 W, about $53.04. Those are illustrative calculations, not measured results for a specific Intel mini PC or FFmpeg setup.
Estimate the annual electricity cost
For a machine running all year, calculate:
Average wall watts ÷ 1,000 × 8,760 hours × electricity price per kWh
As an Amazon Associate I earn from qualifying purchases.
Equivalently, multiply average watts by 8.76 and then by the price per kilowatt-hour. The 8.76 factor converts one watt running for 8,760 hours into annual kilowatt-hours. Use the all-in marginal rate from your own electricity bill, expressed in dollars per kWh, for a local estimate.

| Average wall power | Annual energy at 24/7 operation | Approximate annual cost at $0.173/kWh |
|---|---|---|
| 10 W | 87.6 kWh | $15.15 |
| 20 W | 175.2 kWh | $30.31 |
| 35 W | 306.6 kWh | $53.04 |
The $0.173/kWh rate is the U.S. residential average for 2025, reported by the U.S. Energy Information Administration in 2026; the annual data are preliminary. These wattage values are scenarios chosen to illustrate the calculation, not benchmarks for Intel mini PCs. Electricity prices vary by location and tariff.

If the system runs fewer than 8,760 hours in a year, substitute its actual annual hours. For example, multiply its measured average watts by actual hours, divide by 1,000, then multiply by your per-kWh price. This estimate covers the computer’s electricity only; it excludes internet service, purchase cost, cooling and other equipment.
Why there is no universal FFmpeg mini PC wattage
The answer depends on the complete computer’s average power at the wall during your actual streaming workload, not just the processor’s advertised TDP. Intel describes TDP as a thermal design target associated with a theoretical maximum load; it is not the measured wall draw of the whole PC. Intel also notes that power is lower under lighter loads and may temporarily exceed TDP in some conditions.

FFmpeg can read live inputs, filter or transcode media, and write outputs. Intel graphics can accelerate video encoding, decoding and processing in FFmpeg, with paths such as VAAPI and Intel Media SDK/oneVPL. The supported codecs and the acceleration path depend on the particular Intel GPU, drivers, FFmpeg build and chosen encoder. A workload using hardware acceleration may differ from one relying on software encoding, but the exact power difference for your system cannot be inferred from the processor name alone.
There is no measured wall-power result established here for an unspecified Intel mini PC running an identified YouTube streaming command and set of settings. Treat any estimate based on assumed watts as an estimate, not a device-specific prediction.

Measure your own setup at the wall
- Check your electricity rate. Find the marginal price per kWh on your bill or tariff. Use your own rate rather than the U.S. average if you want a local cost.
- Connect a plug-in electricity usage monitor. Measure the complete mini PC at its power outlet, not just a CPU sensor or a TDP figure.
- Run a representative streaming workload. Use the intended FFmpeg input, filters, output resolution, frame rate, codec and hardware-acceleration setting. Let the system settle into its normal operating pattern.
- Record average watts over a representative period. Include typical variations in activity rather than taking only a momentary reading.
- Calculate cost. For 24/7 operation, use average watts × 8.76 × your dollars per kWh. For a different schedule, use average watts ÷ 1,000 × annual operating hours × dollars per kWh.
For a useful comparison between configurations, measure them under the same encode workload, resolution, frame rate, codec, annual hours and electricity rate. Keep whole-system wall power distinct from CPU package power and TDP.
