The power brick that plugs between the wall and your cube converts the 120V/220V (depending on where you live) 60 Hz AC power from the wall to 28 V DC and sends that to the cube. The DC-DC board inside the cube converts the 28V DC into the 5V, 12V and 3.3V (and possibly more) DC supplies for the various components of the cube. That's all.
