APC SRV3KIL-E uninterruptible power supply (UPS) 3 kVA 2700 W

Product Overview

AI-generated summary

The APC SRV3KIL-E is the sort of “small-but-serious” UPS you buy when you’ve got a few critical systems that can’t just ride out a power flicker—think server, storage, network gear, VoIP, or a small office rack where one ugly outage turns into downtime and lost billable hours. At £1,207 ex-VAT for 3 kVA/2700 W, it’s not cheap for a basic UPS, but it’s in the zone where you’re paying for reliability and the APC ecosystem (monitoring and predictable behaviour under load). If your risk is power cuts, sags, or short interruptions, this is the kind of unit that can actually keep everything running long enough for a controlled shutdown or until mains comes back.

That said, I wouldn’t buy it just to “cover a PC” or as a generic backup for non-critical kit. The value depends heavily on your real power draw and what runtime you need—UPSs get expensive fast if you’re trying to chase long run-times. Also, confirm it fits your environment: ventilation, where the batteries will live, and whether you’ll want monitoring/managed shutdown. If you’re running a mix of devices with peaky loads, it’s worth double-checking compatibility with your load rather than assuming the headline watts will translate neatly. Overall: a solid choice for a small business rack with genuinely business-critical uptime needs—just make sure the load and runtime requirements justify the price.
