The manufacturer commented on the review belowSee comments My CyberPower CP1350PFCLCD PFC Compatible 1350VA 810W Pure Sine Wave Tower UPS arrived today in perfect condition and I immediately put it to the test with my oscilloscope monitoring the output under load (my Dell XPS 9000 computer and LCD monitor). I was thrilled to see a nice smooth sine wave output when running on battery power which was not the case with a Tripp Lite model G1010USB that claimed to have a "PWM sine wave" output but instead was a stepped square wave and my computer refused to run with that UPS.If you have a modern computer and it won't work with the cheaper UPS backup supplies when the power fails it is most likely because your computer has a PFC type power supply which WILL NOT WORK on any type of waveform other than a pure sine wave!Some people complain that they wish the battery capacity was higher so they can run on battery power for tens of minutes if not an hour but the purpose of ANY UPS in this catagory is to allow the user to safely...Read more amznJQ.onReady('jQuery', function() { amznJQ.available('popover', function() { var widgetDom = jQuery("#R3RGWTY0YNR57C_imageSection_F3EF8640-AF32-11E5-ABF6-B5D7475B768F"); var images = widgetDom.find(".review-image-thumbnail"); for (var c=0;c

It's dwarfed by my standard mid-ATX towers. Eyeballed relative to one, it's about half the width, half the height, and two-thirds the depth. Positively petite for a tower UPS and roughly the size of the APC it replaced were that one upturned. Extras include a short coaxial cable and an RJ-11 phone wire. Build quality seems quite good, with an attractive combination of gloss and matte black plastic. Once booted, the UPS is completely silent with mains power. It buzzes quietly when on battery. There is no internal fan.That said, let's drill down the major features of the PFC series:Line-interactive - In the consumer world, there are three major types of UPS...Read more
