A UPS for a Delhi office costs between ₹2,500 and ₹1,20,000 in 2026, depending on what you need to protect. A single desktop needs a ₹2,500–₹5,000 line-interactive UPS; a small server or network rack needs ₹8,000–₹35,000; and a proper server room needs an online double-conversion UPS from ₹25,000 up to ₹1,20,000 or more. At CNC (Classic Network and Computers, West Patel Nagar), every quote starts with a free load assessment — we measure what your equipment actually draws before recommending a size.
Here is the real 2026 price list we quote for UPS and power conditioning in Delhi, plus a simple sizing method so you don’t overpay for capacity you’ll never use.

Offline vs line-interactive vs online UPS — what’s the difference?
- Offline UPS (cheapest) — switches to battery only when power cuts. Fine for a basic desktop; the 5–10 millisecond switchover is too slow for servers.
- Line-interactive UPS — adds voltage regulation, so it also handles Delhi’s daily voltage fluctuation without draining the battery. The right choice for desktops, CCTV, and small racks.
- Online double-conversion UPS — the equipment runs on rebuilt power permanently, with zero switchover time. Mandatory for servers, medical equipment, and anything that must never see a dirty waveform.
How to size a UPS correctly (the 70% rule)
Add up the watts of everything the UPS will carry, divide by 0.7, and you have the minimum VA rating. Example: a server drawing 400 W plus a switch drawing 60 W is 460 W → 460 ÷ 0.7 ≈ 660, so a 1 KVA online UPS runs it comfortably with headroom for backup time. Undersized UPS units fail early and give minutes less backup than promised — this is the most common mistake we correct on Delhi office power audits.
Why Delhi offices also need voltage stabilisation
Delhi’s supply regularly swings between 180 V and 260 V, especially in summer. A UPS battery is not designed to absorb this all day — a servo stabiliser or power conditioner in front of your sensitive equipment extends both UPS life and equipment life. We explain the details in our guide on whether your Delhi office needs a power conditioner and how power conditioning protects sensitive electronics.
Frequently Asked Questions
What size UPS do I need for a 10-computer office in Delhi?
Either one 5–6 KVA line-interactive unit (₹35,000–₹60,000 range) or individual 1000 VA units per desk (₹3,000–₹5,000 each). Individual units are cheaper to start; a central unit is easier to maintain. A free load assessment settles it.
How long will a UPS give backup during a power cut?
Standard internal batteries give 5–15 minutes at full load — enough to save work and shut down safely. For longer runtime, external battery banks can extend backup to 1–4 hours.
Which UPS brand is best for offices in Delhi?
APC and Eaton for servers and critical loads; Luminous and Microtek for desktops and CCTV where value matters. CNC supplies and services all four with GST invoice and manufacturer warranty.
Does CNC provide UPS AMC in Delhi?
Yes — UPS units, batteries, and stabilisers are covered under our IT AMC plans, including runtime testing and battery health checks.
