For £104 ex-VAT, this APC Back-UPS 650 is one of those “safe choice” little workhorse units. If you’re protecting a small office setup—think a single workstation, a basic network switch/router, maybe a monitor or two at most—this is exactly the right class of UPS. The value is in the reliability and the fact it’s dead-simple: it’ll handle short outages and brownouts without you having to think about it. I also like that the battery is user-replaceable by APC; it’s a real cost-control feature because you’re not throwing the whole unit away when the battery finally gives up.
That said, I wouldn’t buy it for anything more demanding or power-hungry. It’s not for servers, line-interactive “proper” protection expectations, or anything where you need minutes of runtime—this is primarily there to ride out brief disruptions and keep you from corrupting work. Also, if you’ve got equipment that draws closer to its practical limits (e.g., larger monitors, laser printers, or anything that spikes), you’ll be disappointed. Overall: if you want dependable, budget-friendly protection for one or two small devices in a typical UK office, it’s a sensible purchase. If you need sustained uptime, step up to a higher-capacity model.
