Abstract
The display card determines whether the first power voltage and the second power voltage supplied by the power supply are within inconsistent input timings, and ensure the third power voltage can be generated accurately to the graphics processing unit to work normally. Therefore, even when the display card cooperates with power supplies having different standards, the graphics processing unit is avoided from malfunctioning or being operated imprecisely by inconsistent timings of input power sources in reaching the display card.
