Buying Guide: Ups Power Supply
📋 Table of Contents
1How do I know what capacity UPS I need for my setup?
Add up the wattage of all devices you want to back up (check power labels or specs), then choose a UPS rated for at least that total. For example, a gaming PC and monitor might need 800W, so a 1000VA or 1500VA UPS would be suitable for several minutes of runtime.
2What's the difference between VA and Watts on a UPS?
VA (Volt-Amps) is the apparent power rating, while Watts is actual usable power—usually about 60-70% of the VA rating. For real runtime estimates, multiply the VA by 0.6 to get a closer idea of actual backup capacity.
3Should I buy an online or offline UPS?
Online UPS constantly regulates power and switches instantly during outages, making it better for sensitive equipment like servers. Offline UPS is cheaper and fine for basic protection of PCs and home appliances, though there's a brief switchover delay.
4How long will a UPS actually keep my devices running?
Runtime depends on battery capacity and how much power you're drawing—a 1500VA UPS might run a single PC for 20-30 minutes, but only 5-10 minutes with multiple high-power devices. Check the manufacturer's runtime charts or use their calculator tools for your specific load.
5What should I check before buying a UPS?
Verify the number and type of outlets (standard plugs, IEC sockets), whether it has surge protection for other devices, battery replacement cost, and warranty period. Also check if it fits your space and has a battery management system to keep the battery healthy over time.
