APC SRV6KRIRK uninterruptible power supply (UPS) Double-conversion (Online) 6 kVA 6000 W

Product Overview

AI-generated summary

The APC SRV6KRIRK is the kind of “proper” online UPS you buy when you don’t want to think about power quality anymore. Double-conversion/online models are typically chosen for servers, storage, and networking where a transfer event, dip, or noisy supply can cause expensive downtime. At ~£1.8k ex-VAT for 6kVA/6kW class kit, it’s not a budget buy, but it can be good value if you actually need clean, continuous power and you’re willing to plan the install properly (rack/placement, cabling, and any required battery run-time).

That said, I wouldn’t buy it “just because” you want a UPS. If your environment is mostly PCs/office kit, a simpler UPS can cost a lot less and still do the job. Also, make sure you’re clear on battery runtime expectations—online UPS systems depend on the batteries being sized and maintained for your target outage window. If you’re not going to get the full benefit (right load, right deployment, realistic runtime), you’re essentially paying extra for features you won’t use. For who it suits: small-to-mid server rooms, fibre switches, NAS/SAN, and any business where uptime is worth paying for and power quality is a real risk.
