APC Back-UPS 425VA / 255W UPS Battery Backup Surge Protector (BE425M)

Bottom line: The APC Back-UPS 425VA / 255W UPS Battery Backup Surge Protector ($62.50 on Amazon as of 2026-10-20 22:16 UTC): Up to 15 minutes of runtime on a 100W load — covers most short outages; main trade-off: 255W output ceiling rules out gaming PCs and anything with a discrete GPU.

Pros & Cons

Pros

  • ✓ Up to 15 minutes of runtime on a 100W load — covers most short outages
  • ✓ 6 outlets split 4 battery-backed and 2 surge-only, so wall warts don't waste protected sockets
  • ✓ Wall-mountable, compact chassis fits dorms, apartments and under-desk setups

Cons

  • ✗ 255W output ceiling rules out gaming PCs and anything with a discrete GPU
  • ✗ Runtime shrinks fast above 100W — not a safe-shutdown window for big loads
  • ✗ Only 4 of the 6 outlets are battery-backed
  • ✗ Battery is a consumable; expect replacement well before the chassis wears out

Manufacturer description

The APC Back-UPS BE425M is a compact 425VA / 255W battery backup built for the equipment you never want dropping offline: the router, the modem, the VoIP phone, the small home-office box under the desk. Six well-spaced outlets split the job — four combine battery backup with surge protection, and two are surge-only, so wall warts and non-critical gear stop crowding out the protected sockets. On a 100W load, APC rates the BE425M for up to 15 minutes of runtime, which is enough to ride out the brief outages that account for most interruptions, or to shut a machine down cleanly instead of…

SpecPicks Verdict

SpecPicks scored APC Back-UPS 425VA / 255W UPS Battery Backup Surge Protector 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

Will the APC BE425M keep my router and modem online during a power outage?

Yes — that is its stated design target. APC rates it for up to 15 minutes at a 100W load, and a typical router-plus-modem pair draws far less than that, so real runtime on networking gear alone is usually longer.

Can I run a desktop PC on the BE425M?

Only a very low-power one. The unit tops out at 255W, so a gaming desktop with a discrete GPU will exceed it. It is intended for routers, modems, VoIP phones and small home-office electronics.

How many outlets have battery backup?

Four of the six outlets provide battery backup plus surge protection. The remaining two are surge-only. All six are well-spaced to fit bulkier adapters.

What warranty and equipment protection does APC include?

APC lists a 3-year warranty on the unit, plus connected equipment protection against power-related damage. Check the product listing for the current coverage limit, terms and claim conditions in your region.

Can the BE425M be mounted on a wall?

Yes. The compact chassis is wall-mountable, which is why it is commonly used in apartments, dorm rooms and small workspaces where floor and desk space is tight.
