APC 450VA overview

  • 1Description

Designed for computers, wireless networking devices, gaming consoles, security systems, and other electronics, the Back-UPS BN450M from APC not only provides power to your critical electronics when the power goes out, but also offers surge, spike, and lighting protection for attached devices. It offers six total NEMA 5-15R outlets, two of which are surge-only outlets and four of which are battery backup & surge outlets, with three of the outlets featuring block spacing to allow bulky transformers to be plugged in without covering other outlets.

The BN450M provides an output capacity of 255W / 450 VA, a nominal output voltage of 120V, an output frequency of 50/60 Hz ±3 Hz, an input voltage of 120V at 50/60 Hz ±3 Hz using its included 5' cord with a NEMA 5-15P plug, has a surge energy rating of 180 joules, and a square waveform. Its sealed, lead-acid battery is maintenance-free and has suspended electrolytes and can be recharged in around 8 hours. When its load is 10W, the BN450M has a runtime of around 214.6 minutes and can also run for 37 minutes when its load is 50W, 15 minutes when its load is 100W, 11 minutes when running a half load of 127.5W, 5 minutes when its load is 200W, and 3 minutes when it is running a full load of 255W. Protection is provided by a limited 3-year warranty and a lifetime connected equipment guarantee of $75,000.

General Features

Stay Connected for Hours During Storms and Blackouts
The BN450M is designed to maximize runtimes for devices such as multiple computers and television equipment that consume high amounts of power. After these devices are safely shut down, the BN450M continues to run low power loads (such as home networking equipment) for over 3 hours during extended outages.
Trusted Power Protection and Convenience
The BN450M features a total of six power outlets, all of which shield your devices against dangerous surges and spikes in voltage. Four of these are battery-backed outlets that will continue to provide power to connected devices when there is an outage. This UPS also offers 3 transformer block spaced outlets, so you can connect bulky transformers without covering other outlets.
ENERGY STAR Rated for Efficiency
The Back-UPS BN450M is ENERGY STAR certified for its efficient operation and ability to help realize lower energy costs.
Warranty and Equipment Protection Policy
The Back-UPS BN450M is covered by a limited 3-year warranty. It also comes with a limited lifetime connected equipment protection policy of up to $75,000. APC will repair or replace attached devices that sustain surge-related damage while properly connected to a registered Back-UPS uninterruptible power supply unit.


Safety-Agency Approved
Helps ensures the product has been tested and approved to work safely with the connected service provider equipment and within the specified environment.


Battery-Protected and Surge-Only Outlets
Battery-protected outlets reserve power capacity and run time for connected equipment that require UPS battery backup, while also providing surge-only protection for less critical equipment. Surge-only outlets protect secondary electronics from surges and spikes without reducing battery power used to run primary electronics during an outage.


Battery Failure Notification
This provides early-warning fault analysis on batteries, thus enabling timely preventive maintenance.
Automatic Self-Test
A periodic battery self-test ensures early detection of a battery that needs to be replaced.
Intelligent Battery Management
Helps maximize battery performance, life, and reliability through intelligent, precision charging.


LED Status Display
Quickly understand unit and power status with visual indicators.
Audible Alarms
Provides notification of changing utility power and UPS power conditions.

    APC 450VA reviews

    Back-UPS BN450M is rated 4.6 out of 5 by 58.
    Rated 5 out of 5 by from Not your usual use I bought this to be an emergency backup for a power dual reclining sofa. We have more than our fair share of power outages. I'm not as young as I used to be, and if the outage happens while I'm in the recliner, I'm stuck. They make battery power packs for recliners that are away from outlets, but they're pretty big bucks. B&H had this one on sale, so I thought I'd give it a try. Bingo! Works perfect! I cycled the chair about 10 times with zero problems. I only need it to work once in case I get trapped. Solved the problem, and saved some $$.

    Rated 5 out of 5 by from Very efficient for small loads I have purchased more than four of these units, all of them are in service and none have failed. (I am using them with loads < 100 watts) Many of these small UPS units have abysmal on battery efficiency. (Less than 30%) This unit is significantly better than any other I have run the comparison of battery Minute/Watts to delivered Minute/Watts I LOVE that the beeper defaults to OFF. I dislike that there is a hard coded timer that will shut down the UPS regardless of battery at about 2.5 Hours. I ended up buying two of them thinking the first one was defective. I was shocked when they both shut down at exactly the same time with different loads.

    Rated 1 out of 5 by from Don't buy The layout is very good. Unfortunately, this model doesn't work. We have purchased seven of the current model (with the molded battery connector on the bottom) and three of the previous model (the one where you have to remove the cover and attach the battery cable). The first three (prior model) worked just long enough for us to decide to purchase more, about a month. Then they started failing. The new model fails immediately within five minutes. The unit will beep once and the LED indicator on the power button will start short-flash-green-short-flash-green-long-flash-green and will shut down within 30 seconds. For no reason. Pathetic. We have relied on APC for over twenty years, we've decided we no longer can. Tripp-Lite maybe?

    Rated 5 out of 5 by from Good for short power-outages I live in Florida where we often have thunderstorms with short power-outages (few seconds). Each time my WiFi and router etc would restart... I've bought two BN450M and have connected critical internet equipment to one (router, WiFi, IP-telephone, file servers, total of about 80 Watts), and use the other one for remaining home-automation. I've kept laptops and printer and other power-hungry devices off. I've had the devices for about two weeks and have already experienced several short power-outages, and (HURRAY!) all my connected equipment sailed safely through without any interruption. (The very first power-outage after installation lasted 90 minutes, and that was too much for the capacity of this power-backup, but my intention was just to handle power-outages of less than few minutes, so I'm totally OK with that event!)

    Rated 5 out of 5 by from I can hear it The ups is a great deal for the price. I just wanted something to keep my cable modem and router up during brief power outages. The only complaint I have is that I can hear a faint high pitch whine coming from the unit. My MDF is in my bedroom closet so every once in a while I notice the noise while I'm in my bedroom.

    Rated 5 out of 5 by from Compact UPS Received this UPS free as a product sample. It replaced a large and heavy APC UPS used for my smart TV, DVR and DVD player. A few features that are important to me, as an off-grid homeowner - are the Sensitivity Mode and the adaption to Power Cycling. The latter will likely happen when my backup generator comes on when the solar system (due to days of foul weather) can't provide the household electricity. Haven't had a power failure since setting up this UPS. But I am confident that it will do the job when called upon. [This review was collected as part of a promotion.]

    Rated 5 out of 5 by from The Perfect Small UPS I bought the APC Back-UPS BN450M for my Cable Modem, main Eero router, Ooma, and 8-port switch. It is small and light but has more than enough outlets for this use. It will mostly help with short brownouts, but has enough power to keep these items running for quite a long time. I am very happy with this purchase
