my ups system controls all 3 servers the total load is 0ver 800 watts on this baby and it only cost me £45 of ebay the reason for using this ups system is , last year we had a power cut and it took out my motherboard and 2 harddrives. this ups system will drevent this from happening again. the way this work is there are batterys inside the system that is used to power the system so if there is any cutoff or power spike the system switches to the batterys to stop any damage to the system.
