How do I size a UPS for a home office?

Measure the actual wattage of the PC, monitors and network devices that must stay on, then choose a UPS whose watt rating exceeds that load with sensible margin. VA alone is not enough because each model also has a watt limit.

How long will a UPS run my equipment?

Runtime depends on battery capacity, battery condition and the connected load. Use the manufacturer's runtime chart for the exact UPS and measured wattage rather than a generic duration claim.

What is the difference between line-interactive and online UPS designs?

A line-interactive UPS corrects common voltage variations and switches to battery during an outage, while an online double-conversion unit continuously regenerates its output. Online models offer stronger isolation but usually cost more and use more power.

Is pure sine-wave output important?

Pure sine-wave battery output is the safest choice for modern active-PFC PC power supplies and sensitive equipment. Confirm the waveform specification in battery mode, not only when mains power is present.

Can a UPS power a gaming PC during load shedding?

A normal desktop UPS is primarily intended to bridge short interruptions or allow an orderly shutdown, not sustain high-load gaming through a long outage. Size from measured gaming load and the manufacturer's runtime curve if longer operation is required.

Should the router and fibre ONT share the UPS?

Keeping the router and ONT powered can preserve connectivity when the ISP network remains available. Include both devices in the load calculation and provide the correct output connections.

Can a UPS shut down a PC automatically?

A UPS with compatible USB or network management can signal supported shutdown software when battery capacity becomes low. Test the configuration periodically rather than assuming the cable alone enables it.
