very pleased to have got the little retention post at the blank end of the power supply (on the right front corner) pretty much exactly right the first try ^_^
the dowel in back (slightly visible here, more visible on the other side) is the other retention clip.
anyway the switch LED is powered by actual DC power out, the switch controls AC power in so the power supply is completely actually off when it's in "off" position, not just in standby or something. (It uses like 1.4 watts in standby so it's not like it's a lot, but why use any when you don't have to?)
