APC SRV1KRIRK uninterruptible power supply (UPS) Double-conversion (Online) 1 kVA 800 W 3 AC outlet(s)

Product Overview

AI-generated summary

The APC SRV1KRIRK is the kind of small online UPS you buy when you don’t want to be thinking about power quality at all. Double-conversion generally means your connected gear gets a steady, conditioned supply regardless of what the grid is doing—so it suits things like network gear, VoIP, lab/office servers, NAS units, and any “it must stay up” IT kit where a hiccup can turn into downtime and calls. At £436.43 ex-VAT, it’s not cheap for a 1kVA class device, but the value is in reliability and predictability rather than raw battery runtime.

That said, it’s also worth being honest: if your priority is long runtime during outages, this size/unit cost won’t magically give you hours of backup. You’ll want to match the UPS to your actual load and realistic outage expectations (and check whether extended runtime options/battery behaviour matter for your use case). If you only need basic protection for a couple of desktops or you’re on a reasonably stable supply where brief sags/brownouts aren’t an issue, you could often spend less with a simpler line-interactive UPS and be fine.

**Who should buy:** UK SMEs and IT teams protecting critical “always-on” business infrastructure where stability matters more than chasing the lowest upfront cost. **Who should skip:** anyone mainly concerned with very long backup times, or buyers looking for maximum value without investing time in load sizing and outage planning.
