Manufacturer description

When the power drops, the APC Back-UPS BE550G keeps your desk alive long enough to save work and shut down cleanly. This 550VA/330W battery backup delivers up to 22 minutes of runtime on a 100W load, enough to ride out most short outages with a router, modem, NAS, and a small PC still online. Eight well-spaced outlets split into four battery-backup-plus-surge and four surge-only, so you can prioritize the gear that must stay up and still protect printers and chargers on the surge side. RJ45 Ethernet line protection shields your network drop from surges traveling in over the cable, a common…

SpecPicks Verdict

SpecPicks scored APC UPS 550VA/330W Backup Battery Power Supply for PC using a rating × review-volume × price-fit model applied to published specs and reviews across the power protection category. APC's power protection lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for power protection of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

How long will the APC BE550G run my equipment during an outage?

APC rates the BE550G at up to 22 minutes with a 100W load. Heavier loads draw the 550VA/330W capacity down faster, so a full desktop plus monitor will get considerably less than a router-and-modem setup.

Can the BE550G power a gaming PC?

Not a high-draw one. The 330W output ceiling suits home-office PCs, Wi-Fi routers, modems, external drives, NAS units, and smart-home devices. A gaming rig pulling 500W or more exceeds what this unit can carry.

Are all 8 outlets battery backed up?

No. Four outlets provide battery backup plus surge protection, and the other four are surge-only. Put your PC, modem, and router on the battery side and leave printers or chargers on the surge-only outlets.

Can I replace the battery myself when it wears out?

Yes. The BE550G uses a user-replaceable battery, APC model APCRBC110, which is sold separately. That lets you keep the same chassis through multiple battery cycles instead of replacing the whole UPS.

Does it protect my internet connection as well as the outlets?

It includes RJ45 Ethernet data-line protection alongside the outlet surge circuitry, so surges arriving over the network cable are blocked too. APC covers connected gear with a 3-year warranty and equipment protection.
