I'm having difficulty selecting the correct UPS for my home configuration.
I have 2 machines I'd like to keep online. We have been having daily power failures (2-4 seconds) and I think that can't be good for the H/W.
So I got a cheap Ultra UPS but it turns out this was completely the wrong choice for 2 systems that have 500 W PSU's each. I'm not sure what I expected, but I didn't expect the UPS to just shut off.
The nominal load for my systems should be around 130 W, and if the GPU is working hard then it could get as high as 400W.
Still I know the rules - I should have gotten at least a 1200W UPS.
So, now is this 250W UPS utterly useless?
