There is no single monthly electricity cost for a 24/7 YouTube stream on a Dell OptiPlex Micro. The answer depends on the exact computer and setup, its average power draw at the wall while streaming, and the electricity rate on your bill.
You can calculate a useful estimate without guessing at a model’s wattage: measure the running setup, convert its average watts to monthly kilowatt-hours, then multiply by your delivered price per kilowatt-hour. The U.S. average below is an example only, not an OptiPlex measurement or your tariff.
Why one OptiPlex cost cannot fit every stream
“Dell OptiPlex Micro” names a family, not one fixed configuration. Models, processors, memory, attached storage and other components vary. So do the stream workload and the peripherals that are left on. A figure quoted without those details can look precise while answering a different question from yours.
The computer’s power supply label is not a measurement of its usual consumption. For example, Dell’s OptiPlex 3070 Micro specifications list a 65 W supply and its average efficiency. Those details describe the supply, not the computer’s observed draw while broadcasting. Multiplying 65 W by every hour in a month would treat its rated capacity as if the computer continuously used that much power.
Even official computer records need careful reading. An ENERGY STAR record for a Dell OptiPlex Micro 7010 configuration gives values for specified idle, sleep and off test categories, as well as a model TEC figure. Those are useful certification data for that configuration and those categories. They are not measurements of that machine running a 24/7 YouTube stream, so they cannot stand in for your streaming average.
The practical input is average AC power drawn at the wall during the real workload. That boundary matters: a computer-only reading excludes a display or other equipment, while a reading at a power strip may include it. Pick the boundary that matches what you want to budget, then keep it consistent if you compare arrangements.
Measure average wall power while streaming
Use a plug-in electricity meter or another suitable meter that reports power in watts. Put it between the mains outlet and the equipment you intend to count. Start the stream with the same video, resolution, encoding settings and peripherals you plan to use overnight. A reading taken before the broadcast starts, or while the computer is idle, answers a different question.
Do not rely on a single instant reading if the meter or workload fluctuates. Let the stream run normally and observe the readings over a representative period, long enough to include ordinary activity such as encoding, playback and any expected transitions. Use the meter’s reported average if it provides one; otherwise, record readings at intervals and calculate their arithmetic mean. You are estimating the usual draw, not trying to capture a brief peak.
Write down what is included. If the computer, monitor, audio interface and router all run from the measured strip, the average covers those items together. If you measure only the OptiPlex, the result does not include the router or other equipment. This distinction is especially useful when a stream remains online while a display is switched off, or when a router serves the rest of the home regardless of the broadcast.
For a fair comparison between two PCs or configurations, measure them under the same stream workload and with the same measurement boundary. Keep the resolution and encoding settings alike, and either include the same peripherals or exclude them from both readings. A comparison made with different workloads can reflect the settings rather than the hardware. For practical setup checks before leaving a stream unattended, see this YouTube live-streaming preflight checklist.
A wall-power measurement does not have to become a project. The aim is to replace a guess with a defensible average that matches your own channel. If you cannot measure today, use a clearly labelled hypothetical wattage in the calculation, then replace it when you can take a reading. Do not present that placeholder as an OptiPlex specification.
Convert the reading into 30-day energy use
Electricity bills usually charge for energy in kilowatt-hours (kWh), while a meter may show power in watts. For a continuous 30-day month, there are 24 hours in each day. Convert watts to kilowatts by dividing by 1,000, then multiply by the hours running:
Monthly energy (kWh) = average wall watts × 24 × 30 ÷ 1,000
Since 24 × 30 ÷ 1,000 equals 0.72, the same calculation can be written more simply:
30-day energy (kWh) = average wall watts × 0.72
That is a conversion factor, not a claim about how much any OptiPlex draws. For example, insert your measured average in watts in place of the variable. A measured average of W watts gives W × 0.72 kWh over 30 continuous days. Keep more digits through the calculation and round the result at the end, rather than rounding your wattage early.
A calendar month may contain a different number of days, and a stream may not run for every hour. For d operating days, use average watts × 24 × d ÷ 1,000. If it runs for h hours instead, use average watts × h ÷ 1,000. For example, scheduled maintenance or a planned shutdown reduces the operating hours in the same direct way; there is no need to call a 30-day estimate an exact bill forecast.
It can help to keep a short calculation note alongside the measurement: average watts, what was plugged into the meter, stream settings, operating hours and the month length assumed. If you later change the video format, add a display or move the equipment onto a different power strip, you can see whether the comparison remains like-for-like. The HD-versus-SD guide for YouTube Live can help you think through stream quality as one of the settings to hold constant while measuring.
Apply the electricity price on your bill
Once you have monthly kWh, multiply by the applicable delivered electricity price per kWh:
Monthly electricity cost = monthly energy (kWh) × price per kWh
If your energy price is shown in cents, convert it to dollars before multiplying. For a rate of r cents per kWh, the dollar rate is r ÷ 100. A measured setup using E kWh at that rate costs E × r ÷ 100 dollars for the period. Use the unit printed on your bill and check whether it is a per-kWh price rather than a daily or monthly charge.
Your bill may include more than one charge, such as a supply or delivery component, a fixed customer charge, taxes or fees. The U.S. Energy Information Administration describes its average retail price as including delivered-electricity costs such as generation, transmission, distribution, taxes and fees. Your own account may itemise these differently. If you want a marginal estimate of the extra cost of running the stream, use the variable per-kWh charges that apply to additional use; a fixed monthly account charge will generally be there with or without this computer. If instead you want an allocated share of the full bill, explain which charges you included.
Rates can vary by location, supplier, plan and time of use. If your bill has time-of-use pricing, a single average rate can conceal a difference between when you run equipment and when electricity is cheaper or dearer. Use a weighted average based on when the stream operates if you have the rate information; otherwise label a flat-rate estimate as an approximation. The number on a national comparison page is not a substitute for checking your own bill.
For a household in India or another country, the same arithmetic works, but use the tariff and currency that apply to that account. Check the bill’s units and billing period. Do not transfer a U.S. dollar example into another country and treat it as a local estimate. If you are unsure which line represents a delivered per-unit charge, your electricity supplier’s current tariff information is a better reference than a broad international average.
Use the 2025 U.S. average as an example, not a tariff
The EIA reports a 2025 U.S. residential average retail electricity price of 17.30 cents per kWh. Its electricity price explanation makes clear that prices vary substantially by locality. The figure is a national residential average, not an OptiPlex measurement and not the rate on every household’s bill. The EIA’s electricity price FAQ provides further context for the reported prices.
At 17.30 cents per kWh, each continuous watt over a 30-day period corresponds to 0.72 kWh multiplied by $0.173 per kWh, or about $0.12. The arithmetic scenarios below show how the method behaves at different assumed wall draws. These wattages are illustrative inputs only: they are not measured OptiPlex values or claims about the draw of a particular model.
| Illustrative average wall draw | Energy over 30 days | Example cost at 17.30¢/kWh |
|---|---|---|
| 10 W | 7.2 kWh | about $1.25 |
| 20 W | 14.4 kWh | about $2.49 |
| 40 W | 28.8 kWh | about $4.98 |
The table multiplies the assumed watts by 0.72, then multiplies the resulting kWh by $0.173. Rounding can make a displayed total differ by a cent. To make the example yours, replace both assumptions: put in your measured average wall watts and your own delivered price. The EIA value is only a transparent reference point for readers who want to check the arithmetic before they have their bill at hand.
Count the full streaming setup you mean to budget
There are two useful questions: what does the computer itself add, and what does the entire always-on arrangement add? A meter at the computer’s plug answers the first more closely. A meter on a power strip with the router, monitor, audio equipment or other devices answers a broader question. Neither is wrong, but stating the boundary avoids comparing one setup’s whole strip against another setup’s PC-only reading.
Include a router only if you are trying to estimate the total electricity associated with keeping the stream online. If the router would remain on even without the stream, its consumption is not necessarily an additional cost caused by broadcasting. Similarly, a monitor may be needed for configuration but not for an unattended overnight run. Measure the actual operating arrangement, not every device you own.
The video workload matters as well. A static devotional image with audio, a lofi playlist, a news replay and a high-resolution visual loop may use different playback and encoding settings. This article does not prescribe one universal workload. When comparing settings, change one thing at a time and measure again. For a music station, continuous playback also matters; see how to keep a YouTube music stream playing when its playlist ends.
A computer left on for streaming may also be responsible for reboots, operating system updates, scheduled jobs or other household tasks. If those happen during the measurement window, decide whether the goal is typical monthly use including them or a clean streaming-only estimate. A longer observation can make occasional activity less dominant, while a short test might capture an update and overstate the usual average.
There is also an operational choice behind the electricity calculation. Running your own PC means you control the machine and its settings, but it must remain powered and connected, and the calculation should include the devices you need for that arrangement. For creators whose specific difficulty is keeping a home computer on through the night, StreamNeo removes that particular need by turning an uploaded video into a YouTube live stream without leaving their own computer running. It is YouTube-only, so it is not a general-purpose broadcast option for other platforms; the electricity arithmetic still depends on what equipment you operate at home.
If the measurement shows that your stream’s energy use is acceptable, the next concern may simply be reliability and a clean unattended setup. If the cost is more than you want to carry, test whether a different configuration or operating arrangement suits the channel, then measure that arrangement on the same basis. A spreadsheet cannot make that choice for you, but it can separate the electricity cost from the other reasons you might choose a particular streaming method.

FAQ
How much does it cost to run a PC 24/7?
Multiply its average wall power in watts by 0.72 to estimate 30-day kWh, then multiply by your delivered price per kWh. For a different month or schedule, substitute the actual operating hours. Without those two inputs, a single monthly cost would be a guess.
How much electricity does a Dell OptiPlex Micro use while streaming?
The model family and the word “streaming” do not establish a universal wattage. Measure the particular computer at the wall during the stream and with the settings and peripherals you intend to use. Certification idle values and a power-supply rating describe different things, not the live-stream average.
Is the 2025 U.S. average the rate I should use?
Only if it happens to match the applicable price on your bill, which a national average does not establish. The 17.30¢/kWh figure is useful as a labelled example for checking the calculation. Use your own delivered price for a personal estimate.
Should I count the router and monitor?
Count them if your question is about the total setup and they are included in the measured power. Leave out devices that are outside your chosen measurement boundary, and be clear about that boundary. If a device would be on regardless of the stream, its energy may not be an additional cost caused by broadcasting.
