In every case, there was nothing wrong with them, just dead batteries. I've had good results buying APC Smart-UPS units at excess equipment auctions, usually at less than 5% of full price. Or rather, I've seen a few CyberPower units, but they were low-end home computer units. I have no experience with the other two brands. That kind of anti-customer activity should be discouraged. If you need further information, please ask.ĭo not buy the APC SMX UPSs with their proprietary protocol. Thanks to anybody willing to help me make a good choice.

Batteries seem to last less than APC ones.

Seems like OPTI-UPS and ONLINE USV have the same "Universal" battery policy

Batteries replacement (they claim they use "Universal" batteries that should be available at all major stores but who knows).

I personally would go with Cyberpower because of the lower price, but I'm still not sure about: There is yet again a good availability of replacement batteries. This however heavily impacts on energy efficiency (even when there is no power outage). OPTI-UPS seem to offer "Double conversion" thus providing more filtering and a more stable voltage (see for instance here: ).

NUT doesn't seem to support the PR* line of products (PR2200* is listed as "reverse engineered"). Not sure if I could run it on FreeBSD in compatibility mode though. There is a good availability of replacement batteries.ĬyberPower offers their Powerpanel Linux version so there seem to be Linux support for their devices. Either I get an additionnal card (AP9620 or a Network Management card which is much more expensive), or I consider alternatives. That being said, APC support on GNU/Linux or FreeBSD seems to be lacking lately because of their Microlink protocol. APC Support was very nice and a new unit was sent to me in less than 3 days. I already owned a few APC UPSs (BackUPS Pro) and one failed on me (twice !). Another brand available is Online USV (German brand) but their rackmount UPS are kinda expensive. These are about the only brands I can get around here (Europe).

OPTI-UPS Durable Series DS1500B-RM (~ 720$).CyberPower Professional Series PR1500ELCDRT2U (~ 670$).I was wondering if you could suggest me some UPS (with true sinewave output) with good FreeBSD support. I would like to put it in my (pseudo) 19'' rack in order to make better use of the space. Therefore I have to choose an UPS with good FreeBSD support in order to shut it down nicely in case power goes down for a long time. Even though I heard that ZFS can cope pretty well with power failures (if you have cache at least - which I don't), IMHO it'd be better not to rely on that alone. Since this server stores all of my data and serves as NAS, I would like to avoid sudden shutdowns due to power outage. I own a server on which I plan to install FreeBSD 9.1 with ZFS.
