Undependable Power Supply

Posted by Jim Jagielski on Tuesday, May 13. 2008 in Technology

Through the years, I've used lots and lots of UPSs. Lots. I have never had such troubles as I have had with the Cyber Power units. They are basically worthless. They have a lifetime of maybe 1 year (with basically NO usage at all... Maybe a total of 3 cycles, down to only say 75% capacity) and fail without warning. Power hiccup and they simply die. You plug 'em back in, run the diagnostic tests and "Lordy Lordy All is in perfect operating condition!"... unless, of course, you unplug the unit from the wall at which point it will go belly up and die with nary a whimper. I can see UPSs failing... it happens, sure. But with every other UPS type I've ever used I've gotten advance notice when the unit is starting to go south. Not with these. You have absolutely no idea if it's good or bad. It will fail at the drop of a hat and with no warning at all. Avoid 'em.
