Abstract
A power subsystem including a mechanism for satisfying a predetermined power limit in a computer system. The power subsystem may include a split power supply and a voltage regulator. The split power supply may include at least a first voltage supply line and a second voltage supply line. The voltage supply lines may be closely matched voltage sources, each configured to provide relatively the same voltage amount. The voltage regulator may step-down a voltage provided by each of the first and second voltage supply lines to generate a desired voltage for a load. The first voltage supply line may be isolated from the second voltage supply line to limit power provided through either the first or the second voltage supply line from exceeding a predetermined power limit. The predetermined power limit may be a power limit set by U.L. standard #60950, i.e., 250 Watts.
