I need a UPS with my new desktop computer, but I do now know which UPS is the best to go for. I have seen some UPS brands and some are not available in Pakistan, and are shown as being the best, but I need a UPS which is easily available in Pakistan. I would like the UPS to run the desktop for at least 2 hours, with a tube light, and fan.
You will be better of buying an inverter with an inva tubular battery to go with it. APC is a decent brand but is priced on the higher side. Check what is available in the local shops and make sure you get a very good quality battery with it. I would suggest 1400kva 24volts inverter with two inva tubular battries for your requirement. You should be able to run your desktop along with a fan and tubelight for atleast 8-9 hours provided you have 150amp battries with it.
