A Dell OptiPlex Micro’s 24/7 YouTube streaming electricity cost depends on the exact generation and configuration, its average power draw while encoding, and your all-in electricity rate. Measure the complete system at the wall during the stream you intend to run, then multiply its average watts by 8.76 to estimate annual kWh.
There is no reliable universal “OptiPlex Micro streaming wattage”. An idle certification value, a playback test from a different model, or a third-party estimate can help explain the arithmetic, but none is a measured result for your live-encoding workload. The worked example below is illustrative, not a prediction for your computer.
Why one Dell Micro cost does not fit all
OptiPlex Micro covers different generations and configurations, not one fixed computer. Processor, memory, storage, power settings and background activity differ. So do the encoder, video, codec, resolution and frame rate you run. These affect the work the system does, and therefore can affect its wall draw.
The workload matters as much as the model. A computer waiting at the desktop is not encoding a live stream. Playing a YouTube video in a browser is also different: it receives and decodes video rather than encoding and sending your own programme to YouTube. A reading from either state cannot stand in for a 24/7 live-stream measurement.
Published figures illustrate the problem. ENERGY STAR’s record for the Dell OptiPlex Micro 7010 (D15U), accessed in 2026, lists 7.7 W short idle, 1.3 W long idle, 1.3 W sleep and 0.3 W off for Category I1. These are category-specific certification values, not streaming results. In a different example, U-Labs reported about 18 W average for a tested OptiPlex 7040M playing 1080p YouTube video in Firefox on Linux Mint. That is local playback on that setup, not live encoding.
A further contrast: ServeTheHome reports about 12–14 W idle on 120 V for its tested OptiPlex 7090 Micro. Beat&Win lists 13 W active power for an OptiPlex 5080 Micro i3/8GB/256GB as an estimate. Neither number establishes the streaming draw of your system. Different generations, states and methods should not be ranked as though they were a controlled comparison.
The useful answer for your bill comes from your own machine. Keep the model and configuration, the stream settings, the measured wall watts and your electricity price together. If you compare configurations, compare the same workload and use the same kind of wall measurement.
Measure the exact system during encoding
Measure the complete computer at the wall while it runs the actual intended stream. Include its normal power supply and any equipment whose consumption you want counted. A measurement at the wall captures what is drawn from the outlet, rather than relying on a processor specification or an idle state. This research does not establish a particular meter model, so choose a suitable meter for your local outlet and follow its instructions.
Before recording a reading, configure the stream as you plan to operate it: same resolution, frame rate, codec, bitrate, encoder and source material. A static image with no audio may not exercise the system like a moving video with sound. YouTube’s encoder settings guidance recommends testing with audio and movement similar to the real stream and monitoring stream health. It also recommends constant bitrate encoding and a two-second keyframe interval, not exceeding four seconds. These are stream setup recommendations, not wattage estimates.
Let the stream settle into its normal running state, then observe power across a representative period rather than treating a momentary display as an average. Encoding activity and background tasks can vary. Note the average watts shown by the meter and the conditions that produced it. There is no one observation period established here as universally sufficient; choose a period that captures the normal pattern of your system, and repeat the measurement if the result varies materially.
Record enough detail to make the number useful later: OptiPlex model and processor, memory and storage, operating system and encoder, video format, output settings, and whether other devices shared the meter. If you change the stream from 1080p30 to a higher frame rate, change codec, or add substantial background work, measure again instead of assuming the old average still applies.
YouTube recommends RTMPS and supports H.264, H.265 (HEVC) and AV1 among its encoder options. Its bitrate guidance varies by codec, resolution and frame rate; for example, it lists 14 Mbps for H.264 at 1080p30 and 10 Mbps for AV1 or H.265 at 1080p30. Those are recommended output bitrates, not a formula for computer power. Use the 24/7 bitrate guide to choose a sensible stream target, but base the cost estimate on a wall measurement.
Network reliability is a separate operating concern. YouTube advises leaving 20% upload bandwidth headroom above the stream bitrate, because shared network use or disruption can affect the broadcast. That headroom does not itself tell you how many watts the computer uses. For stream parameters, the recommended 24/7 YouTube settings guide gives a place to plan the output before you measure it.
Calculate monthly and annual energy use
A watt is a measure of power at a point or averaged across a period. A kilowatt-hour (kWh) is energy used over time, which is the unit commonly used for electricity billing. For a computer left on continuously, convert the measured average watts into kWh as follows:
Annual energy (kWh) = average wall watts × 24 hours/day × 365 days/year ÷ 1,000
Since 24 × 365 ÷ 1,000 equals 8.76, the shorter form is:
Annual energy (kWh) = average wall watts × 8.76
For an average of 13 W, the calculation is 13 × 8.76 = 113.88 kWh per year. This is an arithmetic example, not a claim that an OptiPlex Micro uses 13 W while streaming. If you run the stream for less than the full year, use your actual scheduled hours instead: average watts × total hours ÷ 1,000 gives kWh for that period.
For a monthly average, divide the annual energy by 12. With the same illustrative 13 W input, 113.88 ÷ 12 = 9.49 kWh per average month. Calendar months have different lengths, so an invoice for a particular month may differ from this average. A leap year also changes the precise yearly total slightly; for a planning estimate, the standard 365-day calculation is clear and easy to reproduce.
The calculation assumes the average wall draw stays representative across the period. If your encoder spends time in different states, use an average that reflects those states rather than multiplying a brief high reading across every hour. Likewise, if you include a monitor, router or other equipment on the meter, the result is for the combined load. Decide whether you want the computer alone or the full streaming setup and keep the measurement consistent.
Apply your all-in electricity rate
Once you have kWh, multiply by your own all-in electricity price per kWh. Use the rate applicable to your supply and bill, including relevant per-unit charges if your tariff presents them that way. Do not assume a national or universal price: location, supplier, tariff and billing terms differ. Fixed charges may appear on the bill too, but they do not necessarily rise when one more device uses energy; avoid assigning the whole standing charge to the computer unless you are deliberately calculating a broader bill allocation.
Annual electricity cost = annual kWh × all-in price per kWh
Average monthly electricity cost = annual cost ÷ 12
Using the illustrative 13 W draw and a deliberately specified €0.35/kWh input gives 113.88 × €0.35 = €39.86 per year, or about €3.32 per average month. The €0.35 rate is an example input reported in a third-party estimate, not a statement of a current rate in any country. Replace it with your own bill’s rate and currency.
Beat&Win’s page for the OptiPlex 5080 Micro i3/8GB/256GB, accessed in 2026, lists 13 W as active power and gives a continuous-use estimate of 118.1 kWh/year and €41.35/year using €0.35/kWh. Its figures are an estimate, not a direct long-duration live-encoding test. The small difference from the arithmetic above reflects the source’s stated energy figure; the point is to show how assumptions produce a cost, not to treat either result as your bill.
For a useful comparison, keep the measured average and the electricity rate visible. If you are comparing an always-on computer with another operating method, calculate each at the same rate and include the same equipment. A comparison is only as sound as its inputs; a low idle figure for one device does not make a fair comparison with another device measured while encoding.
Read illustrative estimates correctly
A published estimate can help you understand the scale of the arithmetic, but it answers a narrower question than “what will my stream cost?”. Read the model, configuration, power state and method before borrowing its number. “Active”, “idle”, “video playback” and “live encoding” are not interchangeable labels.
| Figure | What it describes | What it does not establish |
|---|---|---|
| 7.7 W short idle; 1.3 W long idle, sleep; 0.3 W off | ENERGY STAR Category I1 values for OptiPlex Micro 7010 (D15U) | The 7010’s average while encoding a live stream |
| About 18 W average | U-Labs’ tested OptiPlex 7040M during 1080p YouTube playback in Firefox on Linux Mint | Live encoding draw, or draw for a different Micro |
| About 12–14 W idle on 120 V | ServeTheHome’s tested OptiPlex 7090 Micro | Encoding power or a universal idle range |
| 13 W active estimate | Beat&Win’s OptiPlex 5080 Micro i3/8GB/256GB estimate | A measured continuous stream result for your computer |
The record and reviews are useful precisely because they name a device and state. None gives a controlled measurement of the exact configuration in this article’s title running your intended 24/7 stream. Do not pick whichever figure makes the budget look simplest and label it “streaming”. Start with your own measurement, then use third-party examples only as context for how much workload and method matter.
When a result surprises you, check the setup before drawing a conclusion. Confirm that the meter is reading the complete system, that the stream is genuinely encoding rather than idle or simply playing a video, and that the recorded value is an average. Look for background jobs, peripherals, or a changed frame rate. Measure again under the settings you actually expect to keep.
Account for non-electricity costs
Electricity is only one part of the operating decision. If you already own the Micro, its purchase cost may be sunk for your immediate calculation, but repairs, replacement parts or eventual replacement still matter over a longer horizon. If you are buying a used system, condition and the exact configuration affect whether it suits the stream; an energy calculation cannot establish that it has enough encoding capability or will remain reliable.
A local always-on setup also depends on the rest of the chain. An internet interruption can stop the broadcast even if the computer stays on. YouTube advises testing in advance and checking stream health. The channel must be verified and have no live-streaming restrictions in the prior 90 days to stream, according to YouTube’s live streaming requirements. These are platform conditions, not energy-cost inputs, and should be checked on the current official page.
Operating effort has a cost even when it does not appear on the electricity bill. You may need to keep the computer, operating system and encoder configured, monitor interruptions, and restart or troubleshoot after a failure. If updates have interrupted your broadcasts, the Windows Update interruption guide is relevant to reducing one avoidable source of downtime; it does not remove the need to test your own configuration.
If the recurring job of keeping a local computer on and recovering it after a drop is the part you want to avoid, StreamNeo removes that specific computer-management burden: you upload the video, provide your YouTube stream key, and the stream can run with your own computer switched off. That changes the operating arrangement, not the need to check channel eligibility, content rights, stream settings and the current terms of any service you choose. Compare the full costs and trade-offs with a local setup rather than assuming one arrangement suits every channel.

FAQ
Can I use the OptiPlex’s idle power to estimate a 24/7 live stream?
No. Idle power describes a different state and does not measure live encoding. Measure the exact Micro at the wall while it runs your intended stream, then apply the formula to that average.
Is the 13 W figure a measured OptiPlex Micro streaming result?
No. It is Beat&Win’s active-power estimate for a specified OptiPlex 5080 Micro configuration, not a direct long-duration test of 24/7 live encoding. Treat it as an illustrative input only; your configuration and workload may differ.
How do I find the electricity rate to use?
Use the applicable per-kWh charge shown on your own electricity bill or tariff, accounting for the relevant variable charges in your all-in rate. Do not use the €0.35 example as a local price unless it matches your actual supply terms.
