1. A high-power Voltage Regulator Module (VRM) comprising:
a first voltage rail circuit board oriented in a first plane, comprising a first plurality of VRM elements, the first voltage rail circuit board being configured to produce a first rail voltage;
a second voltage rail circuit board comprising a second plurality of VRM elements, the second voltage rail circuit board being oriented in a second plane that is substantially parallel to the first plane, and the second voltage rail circuit board being configured to produce a second rail voltage;
a first capacitor circuit board oriented in a third plane that is substantially perpendicular to the first plane;
a second capacitor circuit board oriented in a fourth plane that is substantially parallel to the third plane;
a first plurality of conductors coupling the first voltage rail circuit board to the first capacitor circuit board and to the second capacitor circuit board; and
a second plurality of conductors coupling the second voltage rail circuit board to the first capacitor circuit board and to the second capacitor circuit board.
