A method and apparatus for adjusting power supplied to a device when the device has a first and a second power input. A first voltage level and a ground potential are provided and a second voltage level is created as a function of the first voltage level. The second voltage level is then buffered with a power transistor and, if the second voltage level is needed for a particular device, the buffered second voltage level is selectively applied to the device. The circuit is disabled when the second voltage supply is not needed.

A circuit board module for a supercomputer includes quick connections for power, ground, coolant quick connects, and circuit quick connects. The quick connections provide for insertion of modules with substantial savings in time and effort. The electrical power and ground connections and the liquid coolant connections engage and disengage automatically upon insertion and removal of the modules. The circuit quick connects require only insertion of a camming tool for connection and disconnection. The modules require no bolting or unbolting of clamps or hoses for the various connections.
