We’ve all been there. You’re ninety minutes into a critical project, the deadline is looming, and you’re in that state of perfect flow. Suddenly, the lights flicker, your screen goes black, and a deafening silence replaces the hum of your computer. That horrible, sinking feeling hits your stomach as you realise you’ve just lost an hour of unsaved work. Or perhaps you’re in the final moments of an intense online gaming match, about to clinch victory, when a momentary power blip disconnects you, erasing your progress and frustrating your team. In today’s hyper-connected world, where our work, entertainment, and communication rely on a constant stream of electricity, these interruptions are more than just minor annoyances. They are data-destroying, productivity-killing events. This is precisely the problem the APC Back-UPS BE850G2-FR 850VA UPS aims to solve, acting as a silent sentinel for your most critical devices.
- The APC Back-UPS Essential family provides Assured electrical power protection for wireless networks, computers, game consoles, and other electronic devices at home or in the company.
- 8 power outlets available, 6 of which provide simultaneous battery power and overcharge protection (surge protection) and 2 only Protection against overcharging.
What to Consider Before Buying an Uninterruptible Power Supply
An Uninterruptible Power Supply (UPS) is more than just an oversized power strip; it’s a key solution for digital peace of mind. At its core, a UPS provides two critical functions: surge protection and battery backup. Surge protection shields your sensitive electronics from damaging voltage spikes caused by lightning, grid fluctuations, or heavy appliance use. The battery backup is the hero of the story, instantly kicking in during a power outage or brownout, giving you precious minutes to save your work and shut down your equipment gracefully. This prevents corrupted files, damaged operating systems, and protects hardware like hard drives and power supplies from the shock of a sudden shutdown. It’s an essential investment for anyone who values their data and their hardware.
The ideal customer for a device like the APC Back-UPS BE850G2-FR 850VA UPS is a home office worker, a small business owner, a dedicated gamer, or anyone with a network-attached storage (NAS) device. If you have a desktop computer, external monitors, a router, and other peripherals that need to stay online, a UPS is non-negotiable. However, it might be overkill for someone who only needs to protect a television or charge a laptop (which has its own built-in battery). For those needing only to protect against electrical spikes, a simpler surge protector might suffice. For those with extremely high-power gaming rigs or multiple servers, a more powerful UPS with a higher VA rating would be a more appropriate choice.
Before investing, consider these crucial points in detail:
- Dimensions & Space: A UPS is not a small device. The APC Back-UPS BE850G2-FR 850VA UPS measures 13 x 36.5 x 12 cm and weighs a hefty 4.5 kg. Before purchasing, you must identify a suitable location with adequate ventilation, typically on the floor or a sturdy shelf near your equipment. Some models, including this one, offer wall-mounting options, which can be a fantastic space-saver.
- Capacity/Performance: The “850VA” rating is the key metric here, indicating the maximum load the UPS can handle. You need to calculate the total power draw (in Watts) of the devices you want to protect. A typical home office setup (desktop PC, monitor, router) will be well within the capacity of this model, providing several minutes of runtime. Overloading a UPS will drastically reduce its battery life or cause it to fail, so matching capacity to your needs is paramount.
- Outlets & Connectivity: Consider how many devices you need to protect. This model provides 8 total outlets: 6 with full battery backup and surge protection for critical hardware, and 2 with surge protection only, perfect for printers or lamps. The inclusion of modern USB-A and USB-C charging ports is a significant convenience, allowing you to charge mobile devices even when the power is out.
- Ease of Use & Maintenance: A good UPS should be simple to set up and forget. Most, like this APC model, require you to connect the internal battery before first use—a simple but crucial step. The key long-term maintenance is battery replacement. We found that the battery in this unit is easily user-replaceable, with a convenient access door, ensuring you can extend the life of the UPS for many years without having to replace the entire unit.

First Impressions: A Solid Build with Modern Touches
Unboxing the APC Back-UPS BE850G2-FR 850VA UPS, the first thing we noticed was its weight. At 4.5 kg, it feels substantial and well-built, a reassuring quality for a device tasked with protecting thousands of pounds worth of electronics. The design is functional and understated, a black tower that will blend in discreetly under a desk. Following the clear, pictorial instructions, the first step is to connect the internal 12V battery. A small panel on the bottom slides off, revealing the battery terminal. Connecting it requires a firm push, but it’s a straightforward, one-time setup process. This is a standard safety procedure for shipping UPS units, and it’s something many first-time buyers might overlook.
Once powered on, the unit is completely silent during normal operation, a huge plus for a home office or studio environment where fan noise can be distracting. The layout of the eight outlets on the top is spacious, although as some users have noted, using multiple bulky transformer plugs can be a tight squeeze. The inclusion of both USB-A and USB-C ports right on the front is a standout feature, immediately setting it apart from older designs and showing that APC is catering to the needs of modern users with multiple mobile devices. You can explore its full feature set and user reviews to see how these ports are integrated.

Performance Deep Dive: How the APC Back-UPS BE850G2-FR Holds Up
A UPS can look great on paper, but its true value is only revealed when the power goes out. We put the APC Back-UPS BE850G2-FR 850VA UPS through a series of real-world tests to see if its performance matches its promises. We connected a standard home office setup: a mid-tower PC, a 27-inch LED monitor, a broadband router, and a NAS drive, with a combined load of approximately 300 watts.
Power Protection in Practice: Seamless Switching and Runtime
The most critical test for any UPS is the switchover from mains to battery power. We simulated a power outage by unplugging the UPS from the wall. The transition was instantaneous and seamless. There was no flicker on the monitor, no interruption to the PC, and no dropped network connection—exactly what you expect. A series of audible beeps immediately alerted us to the power loss, which is loud enough to be heard from another room but not so jarring as to be panicked. The power button also began to flash, providing a clear visual cue.
With our 300W load, the UPS provided just over 7 minutes of runtime. This is ample time to save all open documents, close applications, and perform a proper, safe shutdown of the computer and NAS. For a lighter load, such as just a router and a laptop, you could expect significantly longer runtime, potentially keeping your internet connection alive for over an hour during an outage. The unit also includes an RJ-45 port for data line surge protection, safeguarding your router or modem from electrical surges that can travel through phone or ethernet lines, a feature often overlooked but vital for comprehensive protection. This level of reliability is why so many people choose this trusted name for power protection.
Connectivity and Design: A Mix of Convenience and Compromise
The physical design of the APC Back-UPS BE850G2-FR 850VA UPS is one of its strongest assets. Having eight outlets is a significant advantage over smaller, entry-level models. We were able to plug in our entire workstation—PC, monitor, speakers, NAS, and router—into the battery-backed outlets, with a desk lamp and a phone charger plugged into the surge-only sockets. This intelligent separation ensures that battery power is reserved for only the most critical equipment. As confirmed by one user, the ability to mount it vertically on a wall is an excellent feature for those with limited floor space, helping to keep cables tidy and off the ground.
However, the design isn’t perfect. We also confirmed a minor annoyance mentioned in user feedback: the orientation and spacing of the outlets can make it difficult to use all of them if you have multiple large “wall-wart” style power adapters. They can easily obstruct the adjacent sockets. This is a common issue with many power strips and UPS units, but it’s something to be aware of when planning your setup. The front-facing USB ports are, without a doubt, a fantastic modern convenience. Being able to charge a phone and a tablet directly from the UPS, especially during a power cut, is a feature that really sets it apart from older competitors and adds immense practical value.
The Battery Conundrum: A Critical Point of Concern
While our test unit functioned perfectly out of the box, we cannot in good conscience ignore a significant and recurring theme in user reviews: the issue of battery age. Numerous customers have reported receiving brand new, sealed units, only to find a quality control sticker indicating the internal battery was tested one, or even two, years prior to their purchase date. Unsurprisingly, many of these batteries were dead on arrival, unable to hold a charge, rendering the UPS useless until a replacement battery was sourced. The unit would emit a constant beeping alarm and flash a red light, indicating a battery fault.
This appears to be a logistical or stock rotation issue in the supply chain rather than a fundamental flaw in the product’s design. It’s a frustrating and unacceptable experience for a customer buying a new product. However, on the positive side, this issue highlights a key strength of the APC Back-UPS BE850G2-FR 850VA UPS: the battery is designed to be easily user-replaceable. A simple slide-off panel provides access, and a new battery can be swapped in within minutes. While you shouldn’t have to do this with a new purchase, it means that in 3-5 years when the original battery naturally degrades, you can easily and affordably extend the life of your investment, which is a major long-term benefit. We strongly advise anyone who purchases this unit to check the date on the QC sticker and test the battery function immediately upon receipt.
Advanced Features and Missing Accessories
For users with a NAS or a home server, one of the most valuable features of a UPS is its ability to communicate with the protected device. This allows the UPS to signal the server to perform an automated, graceful shutdown when the battery is running low, preventing data corruption if you’re not there to do it manually. The APC Back-UPS BE850G2-FR 850VA UPS supports this functionality via its data port and APC’s free PowerChute software. However, we were disappointed to find—as were many other users—that the required RJ-45 to USB communication cable is not included in the box. This feels like an unnecessary cost-cutting measure on a product at this price point. It’s a standard cable that must be purchased separately, which is an inconvenience for anyone wanting to use this essential feature right away.
What Other Users Are Saying
Synthesizing feedback from dozens of users, a clear picture of the APC Back-UPS BE850G2-FR 850VA UPS emerges. On the positive side, many users praise its silent operation and effectiveness. One user, who works in a home studio, noted it “works perfectly without any noise,” protecting his PC, audio interface, and speakers flawlessly. Another stated simply, “It does the job. Our multiple local outages are absorbed.” This reflects our own experience that when you get a good unit, it performs exactly as advertised and provides true peace of mind.
However, the negative feedback is consistent and impossible to ignore. The primary complaint, by a wide margin, is receiving a unit with an old, dead battery. As one frustrated user wrote, “Product arrived today. Internal battery to be replaced – battery test certificate dated 2021. Unacceptable given the price of the equipment.” Another echoed this, “Like many, I received a UPS with a defective battery dating from 2021.” This significant quality control lottery is the product’s biggest weakness. The secondary complaint is the missing RJ-45 to USB cable, which, while less critical, adds an extra hassle and expense for technically inclined users.
How Does the APC Back-UPS BE850G2-FR 850VA UPS Compare to the Alternatives?
The UPS market is competitive, and while the BE850G2-FR is a strong contender, it’s worth seeing how it stacks up against other popular models from APC’s own lineup.
1. APC Easy UPS BVX1200LI-GR 1200VA UPS
- 1200 VA / 650 W emergency power supply
- 4 Schuko surge protected outputs with battery backup
For those with a more demanding setup, like a high-end gaming PC or multiple workstations, the APC Easy UPS BVX1200LI-GR is a logical step up. Its 1200VA rating provides a higher power capacity and therefore a longer runtime for the same load compared to the 850VA model. It also features Automatic Voltage Regulation (AVR), which actively corrects minor voltage fluctuations without switching to the battery, preserving battery life. The tradeoff is a larger footprint and fewer total outlets. This is the better choice for power users who need more capacity and advanced voltage correction, whereas the BE850G2-FR is more suited for standard home office protection.
2. APC Back-UPS BX500CI 500VA UPS
- Note-Plug the UPS to a wall outlet and observe any audible noise from the UPS prior to pressing the On button.Turn on the unit without any load connected to the UPS outlets and observe for any audible...
- English (Publication Language)
If your needs are more modest, the APC Back-UPS BX500CI offers a more budget-friendly solution. With a 500VA rating and only 3 outlets, it’s designed to protect a single, low-power workstation or just a router and NAS. It’s a barebones, no-frills device that provides essential battery backup and surge protection without the extra features like USB charging ports found on the BE850G2-FR. This model is ideal for someone on a tight budget with minimal equipment to protect. The BE850G2-FR, with its greater capacity and modern features, represents a much more versatile and future-proof investment for a typical user.
3. APC Back UPS PRO 1600VA UPS
- The APC Back-UPS PRO Series offers guaranteed battery backup and surge protection for high performance computer systems, networks, external storage devices, game consoles and other electronics.
- LCD interface - Quick and easy to read, provides information about the utility and UPS conditions
At the premium end of the spectrum is the APC Back UPS PRO 1600VA UPS. This is a prosumer-grade device with a massive 1600VA capacity, a detailed LCD interface for real-time monitoring, and a pure sinewave power output, which is safer for sensitive and high-end electronics. It’s designed for serious enthusiasts, small businesses with critical servers, or anyone running very expensive audio/video equipment. While vastly superior in features and performance, it comes at a significantly higher price. For the average home or office user, the BE850G2-FR provides more than enough protection and features, making the Pro model overkill unless you have very specific, high-end requirements.
Our Final Verdict: A Capable Protector with a Caveat
After extensive testing and analysis, our verdict on the APC Back-UPS BE850G2-FR 850VA UPS is positive, but it comes with a strong warning. Fundamentally, this is an excellent product. It offers a great balance of power capacity, outlet availability, and modern features like USB-C charging, all from one of the most respected brands in power protection. When it works, it works beautifully, providing silent, reliable protection that gives you the crucial window of time needed to save your work and safely shut down during a power outage. For the typical home office user, gamer, or small business owner, its feature set is nearly perfect.
However, the widespread and well-documented issue of units being shipped with old, depleted batteries is a significant gamble. It turns what should be a plug-and-play experience into a potential game of “stockroom roulette.” We recommend this UPS to anyone whose needs align with its features, but only with the strong advice to test it immediately upon arrival and be prepared to process an exchange if you receive a faulty unit. If you’re willing to navigate that potential hurdle, you’ll be rewarded with a top-tier power protection device. If you’re ready to secure your digital life against unexpected outages, you can check the latest price and secure your APC Back-UPS BE850G2-FR today.
