Yeah, i hate that filthy feeling.

Most gpos run 10a max - and i have a 4-port one in my office that i GUARANTEE runs more kit than you do, and i ain't nowhere near tripping. Hell, even a kilowatt pc power supply at 240v is still just over 4amps, and that is rare. And if you overload it's an IMMEDIATE trip, not a 'oh we don't know what did it'.

It ain't you. Waking up finding something's tripped your safety switch is a fault
