APC SRV1KI-E uninterruptible power supply (UPS) Double-conversion (Online) 1 kVA 900 W 3 AC outlet(s)

Product Overview

AI-generated summary

If you’re buying this APC SRV1KI-E, you’re basically paying for “steady power, low fuss.” A double-conversion (online) UPS is overkill for some offices, but for critical kit—network switches, servers, VoIP, storage gear—it’s the right kind of protection because it doesn’t simply wait for the power to go out. Instead, it conditions the mains continuously, which helps if your site has brownouts, dirty power, or nuisance trips. At £403.80 ex-VAT, it’s not bargain-bin pricing, but for the peace of mind on a small rack/office setup, it can be good value—especially if your aim is clean uptime rather than just “keep a PC alive for a few minutes.”

That said, be realistic about capacity and expectations. A 1kVA / 900W class UPS can still be undersized if you’re powering multiple power-hungry workstations or anything with a large surge draw. Also, it’s a “buy the UPS, then plan the batteries” type of purchase: real runtime depends heavily on load, and online units tend to be more power-hungry than line-interactive models. I’d recommend this for small businesses or IT teams protecting a handful of always-on devices, where you want dependable conditioning and not just emergency ride-through. If you only need basic protection for low-power equipment and your power is already clean, a cheaper line-interactive option often gives better bang-for-buck.
