Yeah when I clicked your link to the APC site, it said $180 odd. i usually trust Amazon to reflect a pretty decent price, I don’t often look much further.

think this looks ok for my purpose. Might just bite the bullet on this? £334 not sure how that value goes in the scheme of things. Thanks again everyone. https://www.amazon.co.uk/dp/B0041MP81Y/ref=cm_sw_r_cp_api_fabc_HNH0FVBGAK9YZ8BRGT1K

Sounds good to me. Thanks for the help.

I heard that there were UPS that would communicate with Unraid servers, to be able to shut the array down before the UPS ran out of power, which sounded like a great extra. I'm not sure how i can tell if a UPS is compatible with this feature on unraid. Im looking for a UPS to supply my main unraid server, and my backup if it happens to be running at the time of power loss. I have calculated my Main Server to draw approximately 268W, i have used Outer vision PSU Calculator for this, it also mentioned for a 600 VA UPS. And my server draw approximately 180W, with a recommended of 400VA. Obviously, it cannot be known if the power outage would occur when the backup server is running, so it's best to cover all basis. The server is turned on over IPMI to do the backup, then switched off again... In a ideal world, and I'm not sure if this is possible, it would be convenient for my router to be on the UPS, and if the power is out for a hour or so, it would be able to remain functional... Any advice greatly appreciated.
