There is no single reliable monthly cost for running a 24/7 YouTube stream on a Lenovo ThinkCentre Tiny. You need the exact computer and its measured wall power while streaming, then multiply its monthly energy use by the marginal electricity rate on your bill.
The calculation below makes those inputs visible and gives illustrative arithmetic scenarios, not ThinkCentre specifications. It also keeps the computer’s consumption separate from a Tiny-In-One monitor, internet service and any other equipment.
Why the exact model and your tariff matter
“ThinkCentre Tiny” describes a family of small desktop computers, not one fixed configuration with one known power draw. The specific model, generation, processor and configuration are not stated in this question. Without them—and without a measurement of the PC while it is doing the intended work—there is no evidence-based figure to plug into a monthly bill.
The tariff matters just as much. The same amount of electricity costs different amounts in different places, and the rate that applies to additional use may not be the headline rate printed beside a bill’s total. A household can have separate charges, time-of-use rates or tiers. For this estimate, you want the applicable marginal price: the price for the extra unit of energy your stream adds.
This is an electricity calculation for the computer, not a full operating budget. Internet access, a monitor, a router, speakers, lighting, backup power and any other devices can add costs. Keep those boundaries clear so a useful estimate does not become an unsupported promise about the total cost of a channel.
If you are still deciding how to run the broadcast, compare the energy calculation with the operational work involved in keeping a local computer on and connected. The steps for scheduling a 24/7 YouTube live stream help explain the broadcast side; they do not establish what a particular computer will draw from the wall.
Calculate energy for continuous operation
For a device that draws a steady average of P watts, a 30-day month contains 720 hours. The energy calculation is:
Monthly energy in kWh = P watts × 720 hours ÷ 1,000
Then calculate the electricity cost:
Monthly cost = monthly energy in kWh × your marginal electricity price per kWh
The division by 1,000 converts watt-hours into kilowatt-hours, the unit used on electricity bills. The formula assumes the device is powered continuously for all 720 hours and that P represents its average draw across that period. A stream’s monthly total can differ if the machine is switched off, loses power, or has a workload that changes its consumption.
For example, the arithmetic for an assumed 10 W continuous load is 10 × 720 ÷ 1,000, or 7.2 kWh in 30 days. This is a calculation, not a claim that any ThinkCentre Tiny draws 10 W. If the relevant rate were an assumed $0.15 per kWh, the corresponding cost would be 7.2 × $0.15, or $1.08. The rate is included only to show how the multiplication works; use your own bill’s applicable rate and currency.
Use a consistent month length when comparing options. A 30-day month makes the arithmetic easy to reproduce. For a more exact bill period, multiply average watts by the actual number of hours in that period and divide by 1,000. Do not mix one setup’s 30-day estimate with another setup’s bill-period total and treat the difference as a hardware saving.
Illustrative draw scenarios, not PC specifications
The table uses three assumed continuous loads to show how the formula behaves. None is a measured ThinkCentre result, a Lenovo specification, or a claim about typical consumption. The example rate is also an assumption, not a suggested or universal tariff.
| Assumed continuous draw | Energy in 30 days | Cost at an assumed $0.15/kWh |
|---|---|---|
| 10 W | 7.2 kWh | $1.08 |
| 20 W | 14.4 kWh | $2.16 |
| 30 W | 21.6 kWh | $3.24 |
The useful comparison here is proportional: under the same month length and tariff, doubling the assumed average watts doubles the calculated energy and electricity cost. That relationship comes directly from the formula. It does not tell you which row resembles your computer. The only way to choose a row responsibly is to measure the actual setup or obtain a relevant power figure for the precise configuration and workload.
These figures cover only the assumed PC load. They do not include the electricity used by an external display, router, speakers, lighting, a camera or backup equipment. Nor do they include internet service charges or any separate costs associated with preparing and operating the stream. If several items remain on, measure or estimate each one separately and add the kWh before applying the relevant rates.
A scenario table is useful for planning, but it is easy to mistake example values for a benchmark. Resist that shortcut when making a purchase or budgeting for a channel. An estimate based on your measured wall draw and tariff is more useful than a precise-looking total built from an unspecified computer.
Find the PC’s actual wall draw
Start by identifying the exact model and configuration. Check the label or system information for the model or machine type, generation and processor. This helps you distinguish your Tiny from another member of the product family, but model identification alone still does not give you a measurement for the stream workload.
For a direct estimate, measure power at the wall with an electricity usage meter suitable for your outlet and region. Take the measurement with the computer running the encoder and the kind of content you intend to stream. Keep the intended resolution, frame rate, codec and connected equipment consistent with your planned setup. If the meter can record accumulated kWh over a representative period, that reading can be especially convenient: you can scale the observed energy to the period you want to estimate, provided the workload and operating pattern are representative.
A momentary watt reading is less informative if the machine’s activity varies. A video with movement and audio may exercise the encoder differently from an idle desktop, and a reading taken during setup may not represent steady streaming. Record the conditions alongside the measurement: what was running, whether the monitor was included, and which accessories were powered. If you later change the stream settings or add equipment, remeasure rather than treating the first result as fixed.
Do not substitute the AC adapter’s maximum rating for the computer’s operating consumption. The adapter rating describes a capacity, not a reading of how much power the PC actually uses continuously. Similarly, published figures for a different product or a different configuration are not a direct measurement of your own system.
The operating setup matters for stream reliability as well as energy. YouTube’s encoder settings guidance gives recommendations by codec, resolution and frame rate. For H.264 at 1080p and 30 frames per second, the cited guidance lists a recommended bitrate range of 5–14 Mbps. Treat that as YouTube’s setting guidance, not as a measured power requirement for a ThinkCentre. Choose settings for the content and test the actual stream, including representative movement and audio.
A looping playlist can be a straightforward source for a channel, but source choice does not remove the need to test the encoder. The practical considerations in using a YouTube playlist as a 24/7 livestream source are useful when you are deciding what the computer must keep playing. Measure after you have settled on that real workload, rather than estimating from an idle machine.
Apply the electricity rate on your bill
Once you have a measured average in watts, apply the tariff that would actually be charged for the additional consumption. If the bill gives a straightforward per-kWh rate, multiply that rate by the calculated monthly kWh. Keep the unit and currency explicit in your notes; a number without them is easy to misread when comparing estimates.
If your tariff changes by time of day, calculate each period separately. For example, if the computer’s average draw is effectively steady but different rates apply during different hours, convert each period’s hours into kWh and multiply by that period’s rate, then add the costs. If your bill uses tiers or includes charges that depend on total household consumption, consult the current tariff or bill details to work out the rate applicable to added use. Do not assume the bill’s average cost per kWh is identical to its marginal rate.
A simple worksheet can keep the estimate auditable:
| Input | What to enter | Why it matters |
|---|---|---|
| Average wall draw | Your measured watts under the planned stream workload | Sets the energy estimate |
| Operating hours | The actual billing period, or 720 for a 30-day month | Defines the period being estimated |
| Electricity rate | Your applicable marginal price per kWh | Converts energy into cost |
| Included devices | PC alone, or each separately measured device | Prevents an unclear cost boundary |
Keep the assumptions with the result. If you write down “PC: measured average watts; 30 days; local marginal tariff; monitor excluded”, another person can understand what the number means. A bill estimate that simply says “the stream costs this much” hides the assumptions and can mislead someone with a different tariff, a different computer or a different list of devices.
For readers comparing a local computer with a setup that does not depend on their own PC staying on, electricity is only one part of the decision. Consider whether you want to maintain the computer and network overnight, what happens after a power or connection interruption, and how you will check the broadcast. StreamNeo removes the specific burden of leaving your own computer running for the broadcast: you upload a video, provide your YouTube stream key, and the stream continues with the computer switched off. It is YouTube-only, so it is not the answer if your channel must broadcast to another platform.
Keep the PC and monitor separate
The Lenovo figures sometimes encountered in this context apply to a monitor, not the Tiny computer. Lenovo’s ThinkCentre Tiny-In-One 24 Gen 5 specifications list monitor power consumption of 14 W typical and 34 W maximum. Those numbers describe that separate display; they must not be used as the ThinkCentre Tiny PC’s draw or presented as the energy requirement of a computer running a live stream.
The distinction is especially important because the Tiny-In-One is described as compatible with certain ThinkCentre Tiny and ThinkStation Tiny computers. Compatibility does not make the monitor specification a PC specification. A monitor and a computer are separate electrical loads, even when they are mounted together or sold as parts of a combined working setup. Lenovo’s Tiny-In-One 24 Gen 5 specification page identifies the product whose figures are being reported.
If you will leave a display on during streaming, include its consumption as a separate line in your estimate. If the screen can be switched off while the PC continues to run, your measurement should reflect that planned state. Do not assume that monitor power disappears from the system merely because it is physically attached, and do not add monitor figures to a PC-only estimate without stating that the boundary has changed.
The same rule applies to routers, speakers, lights, cameras and backup units: they may matter to the total cost of keeping a channel available, but they are not the PC. A wall meter on the computer alone gives a different answer from a meter on a multi-device power strip. Either boundary can be useful, as long as you label it and avoid counting a device twice.
Check the stream and the connection before leaving it unattended
Electricity cost is worth estimating, but a low estimate does not establish that a channel will remain live. Test the complete setup before relying on it unattended. Check that the source loops as intended, audio remains present, the encoder continues sending, and YouTube reports a healthy stream. The YouTube live stream settings guidance explains the stream key and encoder settings process; handle the key carefully and use the current instructions when setting up.
Upload capacity is another independent constraint. YouTube’s live encoder network guidance recommends that total outgoing stream bitrate fit within available upload bandwidth, with a 20% margin, and advises testing upload speed and network reliability. That is a recommendation for connection headroom, not a guarantee that a given internet service will hold a stream. Test at the location and time you expect to operate, especially if other people or devices share the connection.
Plan how you will notice and respond to a drop. A local PC may need attention after a power cut, an update, an encoder error or a router problem. Test recovery rather than assuming the system will resume correctly. For a channel built around recorded lessons, streaming recorded SSC exam classes around the clock offers a relevant example of the source-content context, while your own measurement and connection test determine the costs and practical fit of your setup.
The cost method remains simple even when the operating decision is not. Measure what you plan to keep powered, calculate energy across the actual period, apply the rate that applies to extra use, and keep service and equipment costs separate.

FAQ
How much does it cost to run a ThinkCentre Tiny 24/7?
There is no defensible universal figure without the exact model, its measured wall draw under the intended streaming workload and your applicable electricity rate. For a 30-day month, multiply average watts by 720 and divide by 1,000 to get kWh, then multiply by your marginal price per kWh. The scenario figures above are arithmetic examples, not specifications for this PC family.
How much electricity does a 24/7 YouTube livestream use?
For the computer alone, a steady average draw of P watts uses P × 720 ÷ 1,000 kWh over 30 days. Measure the actual setup while it is encoding the planned stream; an idle reading may not represent that workload. Add separately measured displays or accessories only if you want a total for those devices as well.
Are Lenovo’s 14 W and 34 W figures the Tiny PC’s consumption?
No. The cited 14 W typical and 34 W maximum figures are for the ThinkCentre Tiny-In-One 24 Gen 5 monitor. They are not measurements or specifications for the ThinkCentre Tiny computer, so do not use them as the PC’s draw.
Should I use the average rate or marginal rate on my electricity bill?
Use the marginal rate that applies to the extra consumption where possible, because the stream adds energy to your existing use. If the tariff varies by time or consumption tier, calculate the relevant periods or tiers separately using the current bill or tariff details. Keep the rates and period in your notes so the estimate can be checked later.
