UPS Related Help Needed

[Boomwebsearch]

Hi members of the LinusTechTips community forum, I am planning to buy a new UPS unit which has to be able to provide power to a load of 900 watts at the maximum and am not sure which model to select. I prefer to buy one from CyberPower for my usage application and have noticed that they have two models which would match what I am looking for (one would be the CyberPower LX1500GX and the other one would be the CyberPower CP1500AVRLCD UPS. These ones cost within around 10 dollars of each other because they are both on sale and I am wondering what the difference/s would be between them and which one would be the better option.

Get the PFCLCD model instead.

Also your PC doesn't use anywhere near 900W.

The power supply for the PC which I plan to connect to this UPS is going to be 250 watts although I plan to connect my home network, a monitor, and a NAS device to it. Therefore, I wanted to invest in a larger unit which would offer longer run-time also, if the power was to fail. Within this price range there is the CyberPower GX1325U for around 120 dollars and that is similar to the other ones which I am comparing although it has a lower battery capacity and wattage which it would be able to provide. Although, I guess that having active PFC as a compatibility of the UPS is not bad, I do not really need it as the devices which I plan to connect do not have active PFC.

It's not for the PFC, it's for the pure sine wave instead of simulated sine wave.

I think that sine wave would only be needed if you are going to connect a device with active PFC, and since I do not have a device that has active PFC, I guess that it would be good as an added bonus although not really sure if there would be any benefits still of using a sine wave model.

No, some power supplies will shut off when power goes out as the UPS transitions from wall power to battery power with a simulated sine wave.

This is why pure sine wave is best, it will work with everything.

A UPS is useless if your devices turn off when power goes out.
