Frequently Asked Questions
What size UPS do I need for a home computer?
Add up the wattage of the tower and the monitor, then pick a unit with room to spare above that figure. A single desktop and one screen fall under a 600W rating. Leave headroom if you plan to plug in a router or a second monitor later.
What is the difference between a dry battery UPS and one with a built in battery?
A dry battery unit, such as the Hikvision model in this range, connects to an external battery that you buy and replace on its own cycle, which lets you choose the capacity and the replacement timing. A unit with an internal battery arrives ready to run and takes up less space, but the replacement pack has to match the unit. Both are stocked in this range.
Which brands of UPS in this capacity do you stock?
This range covers APC, Vertiv, Kotohira and Hikvision, spanning entry level boxes for a home PC through to premium units for equipment that has to stay running. Availability of any single model changes, so contact us or visit the Karachi showroom to confirm before you order.
Compact backup power for a desktop, a CCTV recorder or a counter PC, with dry battery and internal battery models from APC, Vertiv, Kotohira and Hikvision.
Up to 1kVA UPS
Up to 1kVA UPS units cover the smallest tier of backup power, sized for one computer, a shelf of network gear or a security recorder rather than a rack of servers. Buyers in this range want the load to stay alive through a load shedding cycle or a voltage dip, long enough to save open work and shut the machine down in order. Most of what is here is a tower box that sits under a desk or beside the equipment it protects.
Four makers account for most of what sits in this bracket. APC and Vertiv hold the established end, with the APC Easy UPS BV line on one side and Vertiv Liebert ITON and GXT units on the other. Kotohira fills the middle of the range for buyers who want a plain backup box without extra management features. Hikvision offers a dry battery unit rated at 600W, which pairs with its own recorders and cameras. The price spread runs wide, from entry level units for a home PC through to premium models aimed at equipment that cannot drop mid task.
How to choose
Three decisions settle most purchases in this bracket.
- Start with the wattage your equipment draws rather than the VA figure printed on the carton, because a tower PC and a single monitor sit below a 600W rating while a laser printer on the same outlet will trip it.
- Next comes battery type: a dry battery model takes an external battery that you size and replace on your own schedule, while an internal battery keeps the footprint small and ties you to a matching replacement pack.
- Last, count the sockets you need to keep alive and leave one free, since people add a router or an ONT later and end up daisy chaining a power strip into a unit that was at its limit.
A single home desktop with a monitor is the common case, and an entry level unit carries it through a short outage. Shop counters running a billing PC and a printer want more headroom than the arithmetic suggests, because the printer spikes when it starts. A CCTV setup with a recorder and a handful of cameras runs for hours on a dry battery unit sized for the job. Anyone protecting a workstation that runs long jobs, or a small rack shelf that has to stay reachable, should look at the Vertiv Liebert side of the range and at the parent Computer and Server UPS category for anything above this capacity.
Mega Computer has sold power protection to Pakistani buyers since 1986 and keeps this range on the shelf at its Karachi showroom, so you can compare unit sizes and socket layouts in person before you commit. Orders ship with nationwide delivery across Pakistan, and you can settle by cash on delivery or online payment. Every unit carries its manufacturer warranty, and our team will tell you what that covers on the battery as against the electronics, because the two terms often differ.
One practical note on ownership: the battery is the part that ages, not the inverter, so plan on a replacement well before the unit stops holding charge. Keep the box in open air rather than inside a closed cabinet, since heat shortens battery life faster than load does. If you buy a dry battery model, budget for the battery and the connecting leads at the same time so the unit is ready to work the day it arrives.
