US 10,146,265 B1 · Main board slot power control circuit

Abstract

A main board slot power control circuit will select a lowest priority interface card from a plurality of interface cards to reduce operation frequency, when the system power consumption is found to be too large. The main board slot power control circuit includes a power supply module, a control module, and a plurality of slots. The plurality of interface cards is plugged into the plurality of slots. The control module applies different priorities to the plurality of interface cards. The power supply module detects and determines when the system power consumption is greater than a predetermined value, and the power supply module outputs a control signal to the control module accordingly. The control module selects the lowest priority interface card to reduce operation frequency according to the control signal, and then the next lowest and so on until power consumption is found to be sufficiently reduced.

A main board slot power control system comprising:

a plurality of slots;
a power supply module coupled to the plurality of slots;
a control module coupled to the plurality of slots and the power supply module;
wherein when a plurality of interface cards is plugged into the plurality of slots, the control module is configured to assign different priorities to the plurality of interface cards;
the power supply module is configured to detect and determine whether a power consumption is greater than a predetermined value, and the power supply module outputs a control signal to the control module in response to the power consumption being greater than the predetermined value;
and the control module is further configured to determine whether the plurality of interface cards comprises a same type of interface cards according to the control signal, the control module selects an interface card having a lowest priority from the same type of interface cards to reduce operation frequency when the plurality of interface cards comprises the same type of interface cards.
