Buying Guide
What should you consider when choosing a computer backup power supply?
- Power capacity (VA/W): Match to the total load you want to protect. More devices and higher-power equipment require larger units.
- Outlet mix: Determine how many battery-backed versus surge-only outlets you need for peripherals, routers, and external drives.
- Runtime expectations: Consider typical outages in your area; estimate runtime at a representative load to avoid abrupt shutdowns.
- Display and monitoring: An LCD panel or software that reports battery status helps plan maintenance and response during outages.
- Battery type and lifespan: Sealed lead-acid remains common and affordable; lithium options offer longer life but different handling.
- Form factor and placement: Ensure the UPS fits your desk or cabinet and allows proper ventilation.
- Surge protection: Look for integrated surge protection for sensitive electronics beyond just the battery backup.
Frequently Asked Questions
- How long can a 600VA UPS run a typical computer?
