In general, one large power supply is more efficient than several smaller ones. In addition, in a network environment, you then get additional losses converting AC to DC then back to AC in the UPS.

One of my current projects is the "Allie Moore IPS-35A15V", a high efficiency power supply for my home network. It will supply 12-15V (programmable by a BMS or PMS) at up to 35A to float charge a 12V battery and operate loads. Most home networking equipment use 12V so they can simply be connected to the 12V bus. Other devices use DC/DC converters. (I also plan to develop the "Allie Moore ATX-400DC12V", a 12V DC input ATX power supply.)
