To keep an OBS sleep-sounds stream online during a power cut, battery-back up every part it depends on: the streaming PC and the internet equipment carrying its connection, usually the router and ONT/modem. Size that backup from the actual combined watt load and the runtime you need—not the UPS’s VA label alone. OBS automatic reconnect can help after a network interruption, but it cannot power a switched-off PC or guarantee that a stream will restart unattended after a total shutdown.
What can fail during a power cut
A stream can stop at three different points: the PC can lose power, the router or ONT/modem can lose power, or the connection beyond your apartment can fail. These require different remedies. A router-only backup does not keep OBS running if the PC shuts off, and keeping the PC on does not help if its internet path is down. OBS notes that dropped frames and disconnections can reflect network conditions outside the software. OBS connection troubleshooting
Think of the setup as two independent continuities: electricity for the equipment and a working route to the streaming service. A UPS can help with the first; it cannot establish that your ISP’s wider network remains available during a local outage.
Keep the whole required setup powered
List the devices that matter
For a typical OBS setup, include the PC, router, and ONT/modem in your backup plan. Include a monitor only if you need it to control or recover the setup during the outage; it may not be needed for the stream itself once everything is running. Add any other device the network path or audio playback actually depends on.

Measure the load and choose the outage you want to cover
Check the equipment labels or measure the running setup’s power draw in watts. Decide whether you want to ride through brief interruptions, keep streaming for a longer cut, or have enough power to shut down cleanly. Those are different targets and call for different capacity. Do not assume a runtime from a product’s VA rating or from another person’s setup.
Choose backup power by watts and runtime
Watts and volt-amperes (VA) describe different limits. Check both the UPS’s maximum output watts and its VA rating against the connected load, and follow the manufacturer’s capacity guidance. Then use the manufacturer’s runtime chart for your measured load; actual runtime depends on the battery and its condition. Schneider Electric explains the distinction between watts and VA and recommends matching the connected load to the unit’s capacity. APC: Watts versus VA

| Option | What to check | Best fit |
|---|---|---|
| Computer UPS with battery backup | Output watts and VA, runtime at the combined PC-and-network load, and whether the equipment tolerates the transfer and output characteristics. | Brief interruptions or a controlled shutdown, depending on the unit and load. |
| Home inverter and battery | Capacity for the full setup, expected runtime at that load, installation requirements, and equipment compatibility. | Longer-duration household backup; Schneider Electric India distinguishes this use from emergency UPS backup. |
| Portable power station | Output capacity, runtime at your measured load, transfer behavior, and compatibility with the PC and network equipment. | A possible alternative where its specifications fit the required load and duration. |
Apartment installation, permissions, ventilation, and service requirements vary by building and device. Check local and building-specific requirements before installing an inverter or battery system. For any backup option, follow the PC and power-device manufacturers’ guidance on transfer behavior and output waveform.
Configure OBS to recover from a connection interruption
- In OBS, open Settings → Advanced and find Automatically Reconnect. OBS documents this as the location for the automatic reconnect setting. The available controls and defaults can vary by release, so check the installed version and confirm the behavior with your streaming platform. OBS Studio overview
- Review the retry behavior in your installed OBS version. OBS’s output reference describes configurable reconnect settings and retry intervals that double on each attempt. OBS output reference
- Use a wired connection from the PC to the router where practical. If connection problems continue, check the selected server and bitrate as well as your network; OBS’s connection guidance covers these causes. OBS connection troubleshooting
Automatic reconnect is for an output connection interruption while OBS and the PC are running. It is not a power backup, and it does not by itself restart a PC or prove that OBS, the stream, and the streaming platform will resume after a complete shutdown.

Test the outage and recovery sequence before relying on it
- Save your OBS profile and scene collection, and confirm the sleep-sounds source is still available after a normal restart.
- Connect the PC and the network devices you intend to back up. Test the UPS or other backup under that full load, then compare the result with the manufacturer’s runtime information.
- With a controlled test, verify the stream during a power transition and check that the streaming platform receives it again after a connection interruption.
- Separately test the recovery sequence after a full PC power loss. Confirm what happens after power returns: whether the PC starts, the operating system loads, OBS opens with the right profile, the source plays, and the platform shows the stream.
Do not treat unattended restart as guaranteed. It depends on the backup device, PC firmware, operating system, OBS startup configuration, credentials, and streaming platform. The OBS reconnect documentation covers output reconnection, not a universal end-to-end restart after total power loss.
Troubleshooting: identify which link failed
| Symptom | Likely cause | What to check |
|---|---|---|
| OBS and the PC shut off as soon as power fails | The PC is not on battery backup, or the connected load exceeds the backup’s usable capacity. | Check the UPS output limits and connected watt load; include the PC, not just the router. |
| The PC stays on, but the stream disconnects | The router or ONT/modem lost power, or the network connection beyond the apartment failed. | Back up the required network devices too. If they remain powered, troubleshoot the connection, server, and bitrate; a local backup cannot ensure ISP-side availability. |
| OBS remains open but does not reconnect | The connection may not have recovered, or the installed reconnect settings and platform behavior may differ. | Check the network and OBS reconnect controls, then test with the actual streaming platform. |
| The stream does not resume after a total shutdown | OBS reconnect does not start a powered-off PC or establish a full automatic restart sequence. | Test the PC’s power-on behavior, operating-system startup, OBS launch configuration, source availability, credentials, and platform status separately. |
| Backup runtime is shorter than expected | The real load, battery condition, or the unit’s runtime curve differs from the assumption. | Use the manufacturer’s chart for the measured connected load and account for battery condition; do not estimate runtime from VA alone. |
