Hello Folks, I am in need of a high powered ups for my new system that I am currently working on. I was looking for something along the lines of 2200VA with expandable battery option for extending battery runtime. However, everything I have seen thusfar quotes a 45dba to 50dba noise level. Is there anything out there that is fanless at this power level, or at least runs silently UNTIL it is running of batteries? I need to be able to power a 1KW PSU, a 500W psu, a 30" LCD, a 20" LCD and a bunch of misc peripherals.
