May 7, 20179 yr Hello, I'm thinking of buying a UPS purely for graceful shut down, so not need to rebuild parity in event of power failer. I was thinking of this cheap and cheerful apc option, but might not work well with graceful shutdown automation in UnRaid? http://www.ebuyer.com/703990-apc-back-ups-300-watts-500-va-3-x-c13-input-bx500ci Any thoughts / guidance on good UPS that works well with UnRaid automation please?
May 8, 20179 yr As far as I can see, the linked UPS has no possibility to communicate with the PC/server. So it can't "tell" the PC to shut down if the mains are out. Not very useful for automation. APC units work well with unRAID. Look for a Smart UPS with USB interface. e.g. APC Smart-UPS C 1000VA LCD You might want to read around the forum, there are other brands too.
May 8, 20179 yr Another thought is that a 300 watt power supply might not be enough to keep your unRAID server running while it shuts down? What is the rating of the power supply in your server - you normally want a UPS with a similar or higher watt rating.

Btw - I'm running 3 x 3TB WD Reds, 1 x WD Green 3TB, 2 x M.2 500Gb Samsung Evo SSDs, 2 x 8Gb Corsair Ram and an i7 7700 3.6Ghz cpu Looks like a 600va should be more than enough? I'm thinking this one, any thoughts or guidance? http://www.ebuyer.com/752004-cyberpower-brics-lcd-line-interactive-1000va-600w-avr-ups-br1000elcd-uk Edited May 13, 20179 yr by huntjules wrong link to ups
May 13, 20179 yr Keep in mind, that your tower will power up in an event to prepare for shutdown. Idle specs are not the right assumption.
