APC SRV3KRILRK-E uninterruptible power supply (UPS) 3 kVA 2700 W

Product Overview

AI-generated summary

The APC SRV3KRILRK-E at £1,338.53 ex-VAT is the kind of UPS you buy when you want “reliable and boring” rather than experimenting. APC’s strength is predictable behavior under load—clean power, sensible switching, and good battery management—so this suits offices or small server rooms where downtime is expensive and you don’t want to babysit the hardware. Realistically, it’s a good fit for things like network gear, a single small server, CCTV NVRs, VoIP kit, and general IT infrastructure where brief outages happen and you need enough runtime to ride through them and/or shut down properly.

That said, you shouldn’t treat it as a magic backup for everything. At this price, the total cost picture matters: battery wear, replacement planning, and whether you’ve sized it correctly for your actual equipment draw (especially if you have line-interactive loads like certain PSUs and monitors). If you only need protection for a couple of desktops or light office IT, this is likely overkill. If you need long runtime for bigger loads, you may find yourself paying more than necessary unless the system supports the expansion you actually need (and that’s where many buyers regret not checking upfront).

**Who should buy:** UK SMBs, IT managers, and resellers wanting dependable UPS protection for critical networking/IT gear with sensible runtime expectations. **Who should think twice:** anyone with vague sizing, who needs extended runtime for heavy loads, or who only needs basic protection for non-critical equipment.
