Abstract: A power supply is described. The power supply includes a main power connector and one or more circuit boards rigidly connected to the main power connector, including mechanical and electrical connection. The main power connector has a body that includes a plurality of contacts. The main power connector is configured to mate with a corresponding connector on a motherboard in a computer. The motherboard is coupled to one or more processors. A first plane including a first circuit board in the one or more circuit boards is substantially parallel to a symmetry plane of the body. The symmetry plane includes a direction of insertion of the main power connector when mated with the corresponding connector. The one or more circuit boards include one or more switched mode power supplies to convert an input signal to one or more output signals.
