APC SRV1KRILRK-E uninterruptible power supply (UPS) 1 kVA 900 W

Product Overview

AI-generated summary

The APC SRV1KRILRK-E at £629.90 ex‑VAT is one of those “safe choice” small-office UPS units that’s less about flashy features and more about doing the boring job properly: keeping a server, network switch, or key workstation alive long enough to ride out brownouts and give you time to shut down gracefully. APC is generally reliable with software and battery management, and for typical UK business power issues (brief drops, spiky voltage, noisy sites), this class of UPS can be genuinely worth it—especially if downtime would cause more pain than the UPS costs.

That said, £629 for a 1kVA/900W unit is only a good deal if you’re clear on your load. If you’re trying to protect multiple devices at once (or anything power-hungry), you could end up with a short runtime that’s basically “blink and it’s gone”, which makes it feel expensive. I’d buy this for a single small server, a NAS, router/firewall, or a comms rack starter setup where you mainly want clean power and controlled shutdown—not for backing up a full office of gear.

Who I’d recommend it for: UK SMEs resellers/IT managers standardising on APC for predictable behaviour, and anyone whose priority is reliability and sensible runtime for a modest, well-understood load. Who I wouldn’t: teams needing long runtime (look at larger capacity or additional battery options) or customers who don’t know their actual wattage—because with UPS buying, “looks right on paper” is where people waste money.
