This is absolutely fine and safe for a computer and you'll see no difference compared to a more expensive pure sine unit. Every single time this is posted there's always some idiot fear mongering about simulated sine, and an argument ensues.

Not everything needs a pure sinewave.

I've bought a few of these, a few of their pure sine waves, and over 50 different UPS units of various brands for small office installs. I've replaced the batteries in many of those units a few times over the years (keep in mind all of these units have batteries that will die between 2-5 years depending on different factors). Not saying so to brag or browbeat, just providing background of how I have at least a bit of experience with UPS.

For Pure vs Simulated sine wave, there are definitely devices that won't work with simulated, I've seen it myself many times. One thing to remember that even with simulated, everything will work when there is power, it's when the power goes out and the battery kicks that the more 'sensitive' devices will either just turn off, reboot, or have other issues. A lot of people have experienced this issue and have sworn off simulated sine UPS just to be safe and have a UPS that can work with everything if they get new devices later. People who have never had the issue probably don't think it even exists, thus the arguing (complicated by the fact devices have evolved a bit to handle simulated better and simulated UPS have gotten better too). How do you know you need real vs simulated sine? Trial and error is really the only guaranteed method.

Regarding lithium replacements like lifepo, if you don't know anything about it I'd recommend against trying it unless someone online has demonstrated it works with this particular unit and you get the exact same batteries as they do. Otherwise experimenting with batteries not designed for this UPS kind of defeats the purpose of the battery backup in the first place since it might fail when you need it most.

For CyberPower and this unit specifically, I'd comment that battery replacement is a little more tricky than some other brands. Unless they've changed the design you have to pull the front off the unit and be careful when pulling the batteries out since the front panel is just dangling by it's wired connection to the rest of the unit (could unplug it but then might damage the connector). If you're looking for the easiest and smoothest battery replacement experience should probably go with another brand (although arguably it really only becomes a problem when you have to do it for 5+ units at the same time). Other than that, I haven't noticed any issues with how the CyberPower units operate.

Just my 2 cents in case someone wanted a quick bit of info. Probably more detailed and in-depth reviews on Youtube and such.

Oh, few protips: Write the month and year somewhere on the unit when you first get it. Makes it easier to remember how long the battery lasted. Also although a lot of units supposedly should tell you when the battery is going to die, I've had a lot of them just suddenly give out or the warning will come only minutes before it dies. So it's important to test them, most people say monthly but as long as you do it at least once every several months you might hopefully catch an issue before it happens at a crucial time.

Picked one up for $130 a month ago. Works just fine. Seems to have a nicer run time than the older version.

In a previous thread, some mentioned swapping the lead batteries with LiFePO4 ones. Does anyone know where I can buy the replacement LiFePO4 batteries that will fit?

It will not charge that battery completely the battery chemistry needs 14.5 volts and if you put it in there it will only charge up to about 65% which will reduce your runtime

For the uninitiated, what do you need the difference for? I'm just trying to protect my $700 pc.

Store is closed or I would call -- is this also $110 in stores, any cheaper? I know these are heavy so I'm not sure if they tack on an added cost to the item for online orders?

Surge protector will do. I have a sine wave ups for my NAS server only so it does a safe shutdown. Most other equipment I'll just run a surge protector.

Make sure it's enough power also, I got the smallest one and my windows box rebuild and video card is now more than the unit can supply so it sets off the alarm on it..
