Questions worth asking
Do I really need a UPS for my computer?
A UPS is recommended if you want to avoid data loss or hardware damage during power outages. It provides battery backup so you can save your work and shut down safely, and it also protects against surges and voltage fluctuations.
What is the difference between a UPS and a surge protector?
A surge protector only protects against voltage spikes. A UPS contains a battery that provides temporary power during outages, and it also includes surge protection. A UPS offers more comprehensive protection.
How long can a UPS keep my computer running?
Runtime depends on the UPS capacity and the power draw of your equipment. A typical 1500VA UPS can power a desktop computer for several minutes, enough to save and shut down. For longer runtime, you need a larger UPS or additional battery packs.
What is pure sine wave output and why does it matter?
Pure sine wave output produces a smooth, clean AC waveform similar to utility power. Many modern power supplies (active PFC) require this type of power to operate correctly. Simulated sine wave can cause issues or even damage some equipment.
Can a UPS protect against power surges?
Yes, all UPS units include surge protection circuits. They absorb and divert excess voltage from surges, protecting your connected devices. The level of protection varies, so check the joule rating.
How do I determine the size of UPS I need?
Add up the wattage of all devices you plan to connect. Choose a UPS with a watt rating that exceeds this total. Also consider the runtime you need. For a typical desktop computer with monitor, a 1000VA to 1500VA UPS is often sufficient.
Are UPS batteries replaceable?
Most UPS units have user-replaceable batteries. Over time, batteries degrade and lose capacity. Replacing them extends the life of the UPS. Check the product manual for replacement procedures.
Can I plug a power strip into a UPS?
It is not recommended to plug a power strip into a UPS unless it is specifically designed for that purpose. Doing so can overload the UPS and void warranty. Instead, connect devices directly to the UPS outlets.
The bottom line
For most home and office users, the APC Back-UPS Pro 1500VA offers the best balance of pure sine wave output, capacity, and features. If budget is a concern, the CyberPower CP1500PFCLCD provides similar performance at a lower price. For basic protection of a router and modem, the APC BE600M1 is a dependable choice.
