1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsA fanless mini PC can add only a modest amount to an electricity bill, but the answer depends on its measured wall draw, how long it runs, and the price you pay per kilowatt-hour. In a 2024 wall-meter test, CNX Software measured a MINIX NEO Z100-0dB at 14.7–17.9 watts during YouTube playback. Run continuously, that is about 10.6–12.9 kWh in a 30-day month—roughly $1.27–$1.55 at an illustrative $0.12/kWh, not a universal electricity rate.
What the measured example means for your bill
The cited result is for one fanless mini PC, not an average for the category. CNX Software reported the same 14.7–17.9 W YouTube playback range in two review configurations in 2024:

- Windows 11 with Chrome playing YouTube at 8K60.
- Ubuntu 22.04 with Firefox playing YouTube at 8Kp60.
Both tests used Wi-Fi 6, a VGA monitor connected through an HDMI-to-VGA adapter, and wireless input dongles. The systems and software differed, so the similar ranges do not prove that operating system, browser, or peripherals never affect consumption. See CNX Software’s Windows 11 review and Ubuntu review.
At 14.7–17.9 W, the PC uses roughly 129–157 kWh over 365 days of continuous playback. The bill impact is that energy multiplied by your applicable electricity rate. A separately powered monitor is not automatically included in a PC-only measurement.

Calculate the cost for your schedule and tariff
Use average power measured at the wall, rather than a processor’s advertised power figure or a power adapter’s maximum output rating. The formula is:
Energy (kWh) = average watts × hours ÷ 1,000
Usage cost = energy (kWh) × price per kWh

These examples apply the formula to CNX Software’s 14.7–17.9 W playback range. The dollar estimates use an illustrative $0.12/kWh rate cited by Mini PC Lab; it is not a current or universal tariff. Substitute the usage rate on your own bill. Fixed account charges are not part of the marginal cost of running the PC.

Why a different fanless PC may use more or less
Resolution and frame rate, hardware video decoding, browser, operating system, network connection, USB devices, display arrangement, and power supply can all affect a real setup. So can the measurement boundary: a meter at the PC adapter’s wall plug includes adapter losses and anything powered by the PC, but not a monitor plugged into a separate outlet.
Do not treat processor TDP or the adapter’s rated capacity as measured electricity use by the complete system. GMKtec’s measurement guide explains the difference between processor design power, adapter output capacity, and socket power. ASUS’s official CF40/Fanless Chromebox CF40 energy declaration reports 2.96 W idle, 0.32 W sleep, and 0.13 W off for a representative model under its stated compliance procedure. Those are idle, sleep, and off figures—not YouTube playback results—and should not be compared directly with the MINIX playback test.

Measure the setup you actually plan to run
- Choose the measurement boundary. For the mini PC alone, plug an energy meter between the wall outlet and the PC’s power adapter. To include a separately powered monitor, measure it separately or use a clearly defined combined setup.
- Recreate a representative session. Use the browser, operating system, video quality, network connection, peripherals, and monitor arrangement you expect to use.
- Record accumulated kWh and duration. A reading over a representative session captures changes in consumption better than a brief glance at an instantaneous watt reading.
- Calculate energy and cost. Divide accumulated kWh by session hours to find average kW, or use the meter’s average-watt figure if available. Multiply the energy used over your schedule by your applicable per-kWh rate.
GMKtec’s guide to measuring watts and kWh covers the calculation and meter boundary. The value of your own meter reading is that it reflects your equipment and conditions, rather than assuming another PC behaves like the MINIX review unit.

Keep a YouTube stream running without leaving the PC on
If your goal is continuous playback of uploaded videos as a YouTube live stream, a fanless mini PC is one do-it-yourself option, but it still needs power, a working internet connection, and a streaming setup kept running. A cloud service is an alternative when you do not want a computer or home connection to stay on.
