[QUOTE="Lordedmond, post: 583029, member: 44824"] Bet its the UPS chucking spikes out , they do not produce good sine wave ( the very best ones do ) its more of a rounded square wave that could be causing PSU problems. They also produce odd order harmonics 9th these also can cause random events to happen . The OP did state the he had an event with the UPS 20% down in 20 secs is odd the UOS should do 15 mins if correctly sized . I would look else where for the problems [/QUOTE]
