So I have experienced two blackouts for past month in my apartment, we've been getting them often thanks to the idiots living next door (we share the same fusebox unfortunately). I have purchased UPS, this type: http://www.apc.com/resource/include/techspec_index.cfm?base_sku=BE400-FR It has failed me on both occasions. It can power mac pro (Quad, 2009, 4x HDDs, HD5870)+24" Display in sleep mode, but when I power it up so I can shut it down, it turns off after 3 seconds or so. It's probably my own fault that I didn't check requirements for Mac Pro before purchasing but maybe I could have faulty unit? All I really want to do is to power off the computer, which can take around 30-40 secs so I guess I'm not asking too much? Seems like power draw in the idle state is a lot for that UPS to handle. Can someone tell me what specs should I be looking at when getting a new UPS?
