Summary: Connect to 110 VAC. Plug in Mac. Connect UPS and Mac with included USB cable. Turn on the Mac and OS X finds and identifies the UPS. The shutdown preferences can be found in "System Preferences" or by clicking on the icon, a rectangle with a lightning bolt inside, in the toolbar at the top of the screen. Select the shutdown parameters and you're done. Battery charge as a percentage shows next to the icon. Remaining runtime shows next to the icon when power fails.
Pros: Excellent runtime with iMac G4 1 Ghz PPC
Cons: Included PowerChute software should not be used with Apple Macs. APC did not know this and it caused a lot of confusion.
Summary: I purchased two of these for my LCD tv's that I purchased recently. These are great because they condition the electricity going to your electronics. If your home has a problem like a brown out or black out, you won't get an energy spike. The energy spikes can and will cause damage to TV's, stereos, Tivo's and cable boxes. I think an ounce of prevention is worth every dollar spent on these. Buy one for each item to protect, it's good insurance!
Summary: This is a must have item for any computer user. If you've ever had a power failure in the middle of a project you'll wish you had this piece of gear. Check out the details on the APC WEB site and their price; Overstock beats the MSRP by far. My only issue is that it was sold for less here only a few days ago along with free shipping. Buy one now - still a good price! Super easy to install and use.
Summary: This device is small enough to be placed on the desk or the floor without getting in the way. It runs silently and with no noticeable heat generated. USB connection to the PC and software on a CD to monitor the unit and close the PC in the event of mains power failure. Sufficient capacity to power a desktop PC, router and other equipment e.g. a Humax box. A surge protected additional outlet happily powers a printer.
Great little UPS at a good price and relatively efficient

Summary: Some UPSs I've used get quite warm suggesting that they are not especially efficient. This model seems to remain cool, a lot more efficient than other earlier model APC UPSs I have used. The other advantage is that it comes with a USB interface to both manage the UPS and also to alert the attached device (in my case a NAS) that power has been lost and that it might consider shutting down gracefully.
Summary: I haven't had a chance to use this yet but thought this information would be useful for any other prospective buyers - this thing does not come with its own power cord. Furthermore all the sockets in the back are the same as the 3 pin sockets in a desktop computer so you can't just plug any old thing into it, you have to get an adaptor.
