Got some question regarding UPS/PSU

Lawk Duski · Jun 11, 2015

Hello, im looking for a UPS to buy, now there are some available here but i dont know which brand is it nor i know which ones i need. so i have some questions.
My power supply is Corsair CX600
Does PSU wattage or voltage have anything to do with UPS?
Is there some specific things i should look at before buying the correct UPS?
What is Pure sine wave?
electricity goes off so much here. so to prevent damage to my PC i need a UPS.
Thanks!

The UPS must be able to supply the maximum amount of power that attached devices require. Depending on what is in your PC, that could be 100W-730W just from your PC.
Cheap UPS units output a stepped square wave, a [poor] approximation of a sine wave that generally works, but may put more stress on PSUs and other attached loads. Some PSUs (I don't believe yours is one of them), may even "see" such a waveform as bad power, and shut off.
I personally use Cyberpower APFC units. I believe their waveform is a clipped triangle, which is more similar to a sine wave, particularly the way it crosses the -0- line (e.g. it doesn't "linger" there, as some stepped square waves do). They are not particularly expensive, especially compared to actual true sine-wave units. Like competitors from APC, they have user-replaceable SLA batteries.

whats the number on the ups? like 1500VA or 1000VA or 750 or 500?

They have several models, of varying capacity. I realize you may not be able to purchase from Newegg, but here are the ones they have:

I believe mine are the first and third (sorted by price).
