It looks like APC is trying to make its uninterruptible power supplies a little less power-hungry, with its new Back-UPS ES 750 model promising both a boost in efficiency and a savings, however small, on your power bill. Among other things, the ES 750 (which apparently replaces the previous model of the same name) can automatically cut off power to unused peripherals when your computer's in sleep mode, which APC says should save you on average $40 a year on your power bill compared to competing models. Otherwise, you'll get all the features you'd expect in a model of its class, including ten power outlets (five of which have battery backup), and 450 watts of power which, depending on what you have plugged in, can give you up to 70 minutes of run time. Look for this one to set you back an even $100 when its released sometime in January.
