Does anyone here use one of these UPS?

I have a CP1500PFCLCD with an RMCARD205 and I’ve been reasonably happy with it. I put my stuff in a nice 25u startech rack because cat, so I was looking to take advantage to upgrade to a bit beefier UPS.

The PR1500RT modesls look to use the same network card so I figured I could save some money switching if I stay with the brand.

I just have a concern about fan noise and was wondering how loud or quiet these things are since I will be sitting next to it all day when working. It doesn’t need to be silent, since nothing else in the rack, though currently nothing like the levels of typical rack equipment. I don’t care if it’s loud if power goes out, just what it’s like when it’s on line power with a fair amount of load.

I was also wondering about the perceived value of the cloud (PR1500RT2UC / PR1500RTXL2UC) vs non-cloud version. Does anyone find value in this feature if they’ve used it? It seems quite expensive and maybe fairly redundant to the network card.

I don’t really see myself wanting to add the extended battery module either, but that feature is clearer to me.

Just trying to do some research to balance what I spend vs ending up with buyers remorse because I’m missing a feature I end up wanting or can’t stand the noise it makes. Thank you.
