To estimate the electricity cost of a fanless PC running a YouTube stream 24/7, measure the computer’s average power draw at the wall, then multiply its annual energy use by your electricity rate. The formula is annual cost = average watts ÷ 1,000 × 8,760 hours × price per kWh. The actual cost depends on your PC’s measured draw and your local tariff; a CPU’s TDP or the number printed on its power adapter cannot tell you either one.
Estimate the annual cost at your electricity rate
A year of uninterrupted operation is 8,760 hours (365 days × 24 hours). Convert watts to kilowatts by dividing by 1,000, multiply by 8,760 to get annual kilowatt-hours (kWh), and multiply by the price you pay per kWh.
- Measure average power: Record the PC’s average wall draw in watts while it is doing the streaming workload you want to estimate.
- Calculate annual energy: Average watts ÷ 1,000 × 8,760 = annual kWh.
- Apply your tariff: Annual kWh × your electricity price per kWh = annual energy cost.
For an estimate over a different period, replace 8,760 with the number of hours in that period. The calculation assumes continuous operation at the measured average draw and a constant per-kWh rate. It estimates energy charges; it does not include fixed bill charges or other tariff components that may apply.
Worked example: hypothetical 10 W average draw
A steady 10 W draw for a year uses 10 ÷ 1,000 × 8,760 = 87.6 kWh. The following rates are hypothetical arithmetic examples, not claims about any location’s electricity tariff or a fanless PC’s measured streaming draw. Currency units are shown generically because the applicable currency and rate depend on your bill.

- Elegant Fanless Cooling Design - This fanless PC features passive cooling system that prevents overheat. It provides a quiet and stable computing environment,supports 24/7 operation. While its unique design ensures dust resistance and silent operation, please note that fanless mini PCs will have a surface temperature of 55°C to 70°C, which is hotter than the case temperature of traditional fan-cooled mini PCs, but meets the safety standards of the International Electrotechnical IEC62368-1:2018
| Hypothetical electricity rate | Annual cost at 10 W | Monthly average |
|---|---|---|
| 0.05 currency units/kWh | 4.38 currency units | 0.365 currency units |
| 0.12 currency units/kWh | 10.512 currency units | 0.876 currency units |
| 0.24 currency units/kWh | 21.024 currency units | 1.752 currency units |
| 0.40 currency units/kWh | 35.04 currency units | 2.92 currency units |
For another average wattage at the same rate, multiply a row’s costs by your wattage ÷ 10. For example, a 20 W average draw costs twice as much as 10 W at the same tariff and runtime. Doubling the hours or the price per kWh also doubles the energy cost.
Measure the PC’s whole-system draw at the wall
The key unknown is the computer’s average power while it streams. The available figures do not establish a measured draw for a named fanless PC running a continuous YouTube stream, so an idle reading, CPU specification, or generic mini-PC figure should not be presented as that workload’s actual consumption.

Use a plug-in electricity meter or watt meter to measure the complete PC at the socket during your own streaming setup. Let the stream run long enough to capture representative operation, and use the meter’s average-watt reading if it provides one. The useful measurement is the computer’s wall draw during the work being estimated; this includes power-supply conversion losses that CPU TDP and adapter ratings do not capture.
- Measure the PC alone if you want the PC’s electricity cost.
- Measure the complete setup if you want the cost of everything needed to keep the stream running. Include the monitor, speakers, router, or other equipment in the metered setup and name what was included.
- Use a representative workload. Idle and active readings can differ; do not substitute an idle reading for the streaming workload without noting that limitation.
What the estimate includes—and what it cannot tell you
The result is an energy-cost estimate based on measured average watts, operating hours, and the rate per kWh you supply. It is not a general cost figure for all fanless PCs. A PC’s draw can vary with its hardware, settings, workload, and attached equipment; your measured result is specific to the conditions you recorded.
