March 8, 201313 yr Hindsight...I shouldn't have loaded the wall socket with 2 surge protectors, 2 computers, 4 monitors, etc. Stupid mistakeThat all depends... on what else is on the circuit. It could be you have three sockets in the room and all on the same circuit... there could be 'a gazillion' things plugged in... or e.g. maybe all bedroom sockets are on the same circuit. Could be the socket you plugged into has relatively nothing else on it (not likely but...) then no problem... you see? It's not the socket that was overloaded rather the circuit - and my guess because the failing psu pulled more amps (plus with whatever else was on the circuit) than it should have if running normally, it tripped the breaker. You can fairly easily find out if you were pushing the circuit too hard. 15amp breaker (typically) x 120v and roughly 80% of 1800 watts for a continuous load... (1400w or so). Find out what the circuit is rated for... what is on the circuit (in watts)... add it up and make sure it is less than what the circuit is rated for. A computer (or whatever on the UPS or a powerstrip) will take a bit to determine actually watt usage. There are watt meters one can purchase, but a site like this http://www.extreme.outervision.com/PSUEngine should be sufficient for a ballpark figure.
