I wanted to buy a UPS for my PC. I was going over some and I came across a variety of sine waves that different UPSes generate;
- Stepped Sine Wave
- Modified Sine Wave
- Simulated Sine Wave
I know power in the line is Pure Sine Wave (but this is highly unlikely as dirty power flows in the lines in my country). Which of these waves will cause least damage to PC hardware?
If you wanna know the specific UPS I am talking of, here they are. Look down for 'Power Protection' and Im talking of the first set of Line Interactive UPS.

– fixer1234 – 2015-05-11T16:03:59.9331What exactly is your question? The UPS should actually filter these waves, and not transfer them to your hardware, I think you are worried about nothing. – Ramhound – 2012-10-24T13:04:27.770
The spec says that these ARE the output waveforms – Fasih Khatib – 2012-10-24T13:05:52.087
1The UPS should actually present a sine wave to the downstream side. It does filter out variability in the upstream side, but the downstream components (PC, Monitor, etc.) expect and need a sine wave (AC) coming to them. – EBGreen – 2012-10-24T13:10:54.477
Having said that, it is unlikely that the method that the UPS uses to present a produces waveform will make much difference either way. – EBGreen – 2012-10-24T13:12:15.160
