I have a desktop at my home and for desktop, as we all know that UPS is one of the mandatory part that we should have connected with our system. As we may have some data which may be some important for us and we may not be able to compromise with loosing that data.
So UPS should be like it should be able to provide the power for our system for as long time as possible. this is one of the brands that produce such powerful UPS. I have UPS of this brand for my desktop system. Its backup time is around two hours if it is fully charged. I bought it two year before and till now I didn’t get any issue with it
