If you can carry it, it's portable.
Does anyone here know much about the internals of the 1st Xbox 360 PSU? I'm talking about the big heavy original one (the 203 W one).

In particular does anyone know if each of the 12V lines (3) are separately monitored for overcurrent or just the whole rail? Also, does anyone know at what point the overcurrent protection trips? Thanks a lot.
