So this makes it a straight swap out solution? Buy an ATX PSU that will fit in the case, take out the old PSU, insert the new and connect it up using this cable... That simple?

Is it also the same for the A4000 cable you have available? How does the A4000 version work with the A4000's existing on/off switch that uses a long bar to push the on/off on the actual PSU?
