Recommendation on small business UPS

Hi guys,

Wondering if anyone might be able to recommend a UPS for small office environment. Looking to to enable around 15 minutes up time before safely shutting down a HP Proliant ML30 server and Synology NAS in the event of power outage.

I have done as much research as I can bare at this point. Looking for best bang for buck for around $1500 max $2000. Still undecided on the following:

1) Eaton 5PX 2000VA discounted from $1459 to $1063

2) APC SMX1500RMI2U 1500VA $1562

3) APC SMC3000RMI2U C 3000VA $1927

4) Cyberpower Pro PR2200ELDSL 2200VA $800

Thanks in advance.



    What’s the power draw? I’d go the Eaton but also think that 2000VA sounds like it might be excessive for 15 mins runtime.


    I've just purchased an Eaton from eBay seller futu_online just for home use and after a couple of tests it's living up to expectations.

    As kipps ^^^^^^ said 2000VA does sound a little bit of an overkill but better too much than not enough maybe.


    Power draw Im not 100% sure however the ability to be able to add more devices like PBX, router & switch would be great.

    I'd also prefer Eaton over APC myself and that is in no small part due to APC being owned by parent company Schneider Electric, who are incompetence and negligence personified, but that's a whole other can of worms.

    I've used both brands in my career as a Sys Admin and as a general rule, the Eaton battery packs are much cheaper to replace, their IPM/monitoring/graceful shutdown software is free and works as advertised (if a little rough in the UI) and I haven't seen any failures amongst their PowerWare range for years.

    Also, what these fellow Sys Admins said here and here.

    There was a time when the only UPSs you saw in most server racks and data centres were APC, but that time has well and truly gone since Schneider acquired them back in 2007.

    Why are you doing your research naked?🤨

    From your list, I would go with the Eaton.


    I don't know much about the $500+ price point you're looking at but I assume you have a way of setting it up so the UPS can automatically trigger a safe shutdown for more than one device since you have a server and NAS?

    I know there's ways using a network monitor or something but that was overkill for me and I ended up only protecting my desktop PC (rather than my NAS) with the Cyberpower NAS. Works fine for my needs but not sure if it'll get you 15mins runtime (1200VA) as it depends on power draw needs.
