Ask “stabilizer or power strip for my PC?” and the honest answer is that they solve three different problems. A spike guard stops surges but does nothing about low voltage. A stabilizer (AVR) corrects sagging or spiking mains but goes dark in a power cut. A UPS with built-in AVR does both and keeps you running long enough to save and shut down. If your area sees genuine voltage swings — the reason most people search this in the first place — a UPS with AVR is usually the buy, with a plain stabilizer as the cheaper option when your grid only sags rather than fails. Prices below are Amazon.in and move around; treat them as ballparks.

Buying tips
- Diagnose before you buy: a spike guard fixes surges, a stabilizer fixes sag and swell, a UPS with AVR fixes both plus outages. Buying the wrong one is the most common mistake here.
- If you get power cuts at all, skip the plain stabilizer and buy a UPS with AVR — a stabilizer will not keep your PC alive for the thirty seconds you need to save your work.
- Size it properly: add your PC and monitor wattage, then leave about 30% headroom. A 600VA UPS is roughly 360W of real capacity.
- A modern PC with an 80-PLUS power supply on a stable urban grid may need nothing more than a decent surge protector — the PSU already tolerates a fairly wide input range.
- Plug the PC and monitor into the battery/stabilised outlets, not the surge-only ones. Mislabelled outlets are why people think their UPS failed.
- For a UPS, check that the output waveform (pure or simulated sine) is one your PSU accepts cleanly; some active-PFC supplies are fussy with cheap stepped-wave units.
