APC Smart-UPS On-Line SRT3000RMXLI - 3000VA, 8x C13 & 2x C19, rackmount

Product Overview

AI-generated summary

The APC Smart‑UPS On‑Line SRT is exactly the kind of UPS you buy when you *can’t* afford the “maybe” scenarios—power glitches, brownouts, weird mains quality, or those annoying micro‑outages that don’t trip anything obvious but still upset sensitive kit. In practice, the appeal of an On‑Line double‑conversion design is that it’s much more forgiving for servers, SAN/NAS, network cores, hypervisors, and any infrastructure where uptime and clean power matter more than squeezing every last pound out of the budget. At £3,064.55 ex‑VAT, it’s not cheap, but it’s in the right ballpark for an on‑line, rack‑ready system meant for serious rack deployments rather than “nice to have” office backup.

That said, I’d think twice if your environment is mostly tolerant to short interruptions (e.g., desktop workstations) or you’re only protecting against complete power loss—an on‑line UPS can be overkill, and you’ll pay for complexity you don’t need. Also, sanity‑check your total spend on the eventual battery replacements over the lifecycle, and whether your rack has the space and airflow to keep it happy. Bottom line: this is a solid buy for UK B2B server/network infrastructure where power quality risk is real, but it’s a poor value choice for lighter-use setups where a simpler line‑interactive unit would do the job.
