Watch products with ShopSavvy for price drops, stock alerts, deals and more.

The CyberPower CP900AVR UPS generally operates pretty quietly. From what we've gathered, it does make some noise, but it's usually minor and hardly noticeable unless the battery kicks in during a power outage or while it's charging. Some folks have mentioned a soft hum, but it's not too disruptive, so it should be fine for both home and office use where you might be worried about noise.

The unit has a capacity of 900VA and 560W with 10 outlets—5 of them are battery-backed and surge-protected, while the other 5 are just surge-protected. It also has Automatic Voltage Regulation (AVR) to help keep voltage levels steady and protect your devices from power fluctuations, which is super helpful if you experience brownouts or voltage spikes.

In terms of performance during power outages, it’s generally reliable. Depending on the load, you might get up to 4 hours of runtime with a light 20W load, or around 17 minutes with a heavier 300W load. This should give you enough time to safely shut down essentials like modems, routers, PCs, and home entertainment systems, preventing data loss and preserving settings during power interruptions.

That said, some people have mentioned a few downsides. There are concerns about the battery lifespan and the unit’s USB features for automatic shutdowns, especially with Mac systems. There have even been occasional reports of units failing sooner than expected, though experiences seem to vary.

Despite these issues, many still find the CyberPower CP900AVR a worthwhile investment, particularly with its three-year warranty and solid connected equipment guarantee.

All in all, while the CyberPower CP900AVR does make a bit of noise, it usually isn’t a big deal for most users. If you’re looking for a budget-friendly and reliable way to safeguard your gear from power issues, it’s definitely worth considering. Just keep an eye on those potential USB compatibility and battery lifespan quirks.

It can handle up to 900VA and 560W, making it a good fit for things like desktop computers, routers, and networking gear.

One cool thing about the CP900AVR is its Automatic Voltage Regulation (AVR). This feature smooths out minor voltage fluctuations without needing to switch to battery power. That way, it helps to extend the battery life and keeps your devices powered with a steady supply.

According to the manufacturer's product description, it has 10 outlets in total: five for battery backup and surge protection, and another five just for surge protection. So, you should have plenty of outlets for various devices.

But it's worth noting that there are a few downsides. Some folks mentioned it doesn't have display indicators for battery life and runtime, which could be annoying during longer outages.

Setting it up is usually pretty easy, and the build quality gets a thumbs up. However, there were a few mentions of a high-pitched noise when it's running and mixed results with USB connectivity for specific devices.

Still, if you're looking for balanced performance and reliability in a UPS system, this one seems to check most of the boxes.

Can the CyberPower CP900AVR UPS be used for a gaming PC?

Published: May 22nd, 2024
Last Updated: July 10th, 2024

Yeah, the CyberPower CP900AVR UPS could work well for a gaming PC.

It's got a decent capacity of 900VA/560W and has 10 outlets. Five of those outlets provide both battery backup and surge protection, so you can keep things like your gaming PC, monitor, and router running during power issues. This can really help prevent data loss if the power suddenly goes out.

One cool feature is the Automatic Voltage Regulation (AVR). This keeps minor power fluctuations in check without draining the battery, which is great since gaming PCs can be pretty sensitive to power changes.

The UPS is also pretty compact, which makes it easy to fit into your setup, and it's simple to start using—just plug it in and it starts charging. It weighs about 20.9 pounds, so it's not too tough to move around if needed.

From what we've found, it holds up well during power outages. However, actual runtime depends on what you connect to it. For example, one person reported their Starlink router stayed on for about 1 hour and 50 minutes. So, the time you get will vary based on your gear.

This matches up with what the manufacturer says, and it should give you enough time to save your game and shut down safely.

There are some quirks, though. Some folks have had trouble with automatic shutdown features, especially on Macs.

USB connection issues and software compatibility can be tricky if you're using a Mac, so keep that in mind.

All in all, the CyberPower CP900AVR is a solid pick for keeping your gaming PC and other electronics running through power surges and outages. Just watch out for those potential Mac compatibility hiccups.
