Is it a current trip or an earth leakage one?
i cant be 100% sure i share a house with ten other people and the breaker is in somone elses part of the house (i dont want them sussing it me that keeps blowing the power ill get the shit kicked out of me :)

im pretty sure its an earth leak because of the three switching power supplies (all of them will be leaking a bit i guess)
i was thinking ill get a cumalative spike as they all come on at the same time

i have had the thing running and all seems well, it only trips when i power up
