APC SRV5KRIRK uninterruptible power supply (UPS) Double-conversion (Online) 5 kVA 5000 W

Product Overview

AI-generated summary

The APC **SRV5KRIRK** is one of those “buy once, stop thinking about it” online UPS units. Double-conversion (true online) is overkill for some offices, but it shines if you’ve got **server rooms, storage, networking gear, or anything that really can’t tolerate voltage swings**—especially on shaky sites or where power quality is inconsistent. For £1,543 ex‑VAT, you’re paying for reliability and cleaner power rather than flashy capacity. If you’re reselling or standardising kit across a few client sites, this kind of model tends to be the sensible choice because it’s predictable to manage and less likely to cause headaches during outages.

That said, I wouldn’t rush to buy it for **small desks, POS systems, or anything where a basic line‑interactive UPS would keep people running**. Online UPS units are typically less efficient than simpler topologies, and if you don’t actually need that level of protection, it’s wasted spend. Also worth considering: APC 5kVA/5kW class UPSs usually make more sense when you’ve sized the loads correctly—if you’re running lots of servers and networking you’ll feel the value; if you’re under-leveraging it, the cost per useful runtime won’t look as great. In short: **great fit for critical IT protection**, avoid it when the requirement is modest or power quality isn’t an issue.
