Abstract: A scheme is provided for dynamically adjusting an amount of power drawn from individual power sources to optimize the power usage without violating power limits. Coarse adjustment is provided through dynamic phase reallocation while a fine adjustment is provided through dynamic current steering. By adding a control loop around current steering techniques in digital voltage regulator controllers, power drawn from multiple input rails is balanced. The apparatus allows users to maximize the power delivered to discrete graphics cards without violating PCIe specifications. This allows maximum performance with minimal bill-of-material (BOM) cost.

Abstract: An apparatus is described. The apparatus includes an add-in card having a power connector to receive power other than through the add-in card's host connector. The power connector fitted in a notch of a printed circuit board of the add-in card so that, when the printed circuit board is oriented to have an upper surface with semiconductor chips disposed thereon, an upper surface of the connector is above the upper surface of the printed circuit board and a lower surface of the connector is below a lower surface of the printed circuit board.

Abstract: An apparatus is described. The apparatus includes a semiconductor chip package having a semiconductor chip therein. The semiconductor chip package to communicate a temperature of the semiconductor chip. The apparatus includes a heat sink that is thermally coupled to the semiconductor chip package. The heat sink has fins. The apparatus includes a fan. The apparatus includes a temperature sensing device. The temperature sensing device is to sense a temperature of an ambient before the ambient is warmed by the fins. A rotational speed of the fan is to be determined from the temperature of the semiconductor chip and the temperature of the ambient.
