Recommended tiers
| Tier | Example class | Good fit | Watch out for |
|---|---|---|---|
| Budget | APC BE600M1-class 600VA unit | Router, modem, small switch, tiny utility host | Limited runtime for NAS or larger hosts |
| Best value | CyberPower CP1500PFCLCD-class 1500VA sinewave UPS | NAS plus networking gear and one efficient host | Measure real load before assuming runtime |
| Upgrade | Smart-UPS / managed UPS class | Rack, multiple hosts, clean shutdown signaling | Battery replacements and used-unit age |
What matters most
- USB signaling for shutdown automation.
- Enough watt capacity for the real load.
- Replaceable batteries.
- Runtime long enough for graceful shutdown, not all-night operation.
What I would buy first
For a small home lab, I would protect the router, switch, NAS, and primary host. If budget forces a choice, protect storage and network gear before nonessential compute.
Source checks: APC's BE600M1 page lists a 600VA Back-UPS with 7 NEMA outlets and USB charging; CyberPower's CP1500PFCLCD page describes a 1500VA/1000W PFC sinewave UPS for computers, networking devices, and home entertainment gear.
