I have the base Mid-2011 21.5" iMac. I wanted to protect my investment and my files! The iMac uses an Active PFC power supply so a pure sine wave UPS is required for proper functionality. The USB connection on this unit integrates perfectly with the OSX power save panel. Connect the USB cable and a set of options for automaically shutting down the iMac while being powered by UPS become available. You can adjust to shut down after x minutes or x% of UPS power remaining. I was also concerned about the power draw, and was originally considering a larger unit - but with the iMac and one external drive connected the load is only about 20%, and the estimated battery runtime is about 40 minutes. Checked it by pulling the plug - got the notice on the iMac screen that it's now running on battery and to save your work soon. The display on the unit is very informative and it has a small form factor. For OSX compatibility, price, and performance this UPS can't be beat.


Strong Ventilated Lines up properly Well packaged






Rackmountable, 8x 20amp battery backup outlets that are broken into two groups of four with individual circut breakers for both groups. The LCD panel is a VERY nice touch allowing you to scroll through your output wattage, input/output voltage and Hz, it also gives you a % of what your total power draw through the unit is out of the 1650w availible, tells you your battery charge % and an estimated runtime based on the current power draw, The LCD has a blackout timmer if not used (30sec aprox) usefull when you dont want that bright blue screen on. heavy duty construction and good packaging.
