Thanks Tom, Ill look at that one,
Frank,
Its quite hard to guess power draw as I havent built it yet im going to say its similar to the values tom quoted maybe slightly less.
We get quite a few 5-10 times a year very small power outages and a few longer up to 5 mins however sometimes this trips our electric and its off till I flip the trip switch.
In the small cases i just want it to be protected when it fails I want it to run for 5-10 minutes advising me via email etc that power has been lost and that it will shut down in x mins. Obv i will have to run the modem router off the UPS aswell and probably the POE cctv switch for as long as it can once server is down so we are probably talking 70-150w load max, id suspect towards the lower range.
