The following embodiments further illustrate the points of the present invention in detail, but are not intended to limit the scope of the present invention in any way.

[0023] The graphics card power consumption monitoring and anomaly warning system and method disclosed herein are used to monitor the power consumption of a graphics card and issue warning information when an abnormal situation occurs. As will be understood by those skilled in the art, a graphics card is an expansion card in a personal computer with a graphics processing unit (GPU) as its core. Its purpose is to provide a microprocessor other than the central processing unit to help calculate image information, convert the display information required by the computer system, and provide progressive or interlaced scan signals to the display device. It is an important component connecting the monitor and the personal computer motherboard. Hereinafter, in order to avoid obscuring the focus of this disclosure, the internal components or detailed configurations of the graphics cards included in the various embodiments may be simplified or their unnecessary descriptions may be omitted.

[0024] Please refer to Figure 1 and Figure 2 , Figure 1 This is a functional block diagram of a graphics card power consumption monitoring and anomaly warning system according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the power connection terminal of a display card power consumption monitoring and anomaly warning system according to an embodiment of the present invention. Figure 1 As shown, the graphics card power consumption monitoring and abnormal warning system 1 includes a graphics card 11, a power connection terminal 12, at least one prompting device 13, and a microcontroller 14. The graphics card 11 includes a power element 110. The power connection terminal 12 is disposed on the graphics card 11 and has multiple detection pins, and the power connection terminal 12 is used to connect to a power supply 20. The at least one prompting device 13 is used to output a prompt message when triggered. The microcontroller 14 is disposed on the graphics card 11 and connected to the multiple detection pins and the at least one prompting device 13. It is used to determine an input power provided by the power supply 20 based on a connection status information of the multiple detection pins and a preset power table, determine whether the input power matches a required power of the power element 110, and trigger the at least one prompting device 13 based on the matching result of the input power and the required power. The preset power table contains a correspondence between multiple preset connection states and multiple preset power levels.

[0025] In this embodiment, the graphics card 11 may include a circuit board. The power connection terminal 12 is a connector disposed on the circuit board of the graphics card 11 for receiving power supplied by the power supply 20. Figure 2 As shown, the power connector 12 has multiple power pins 121 and multiple detection pins 122. For example, the power connector 12 can be a PCIe 5.0 12VHPWR connector, which includes 12 power pins 121 and 4 detection pins 122. The 12 power pins 121 can be used to transmit a 12-volt current signal, supporting a maximum input power of 600 watts. Please refer to Table 1, which shows the correspondence between the pins and signals of the PCIe 5.0 12VHPWR connector.

[0026] Table 1:

[0027] foot position Signal 1～6 +12V3 / V4 7～12 COM S1 CARD_PWR_STABLE S2 CARD_CBL_PRES# S3 SENSE0 S4 SENSE1

[0028] The four detection pins 122 are used to connect to the power supply 20, and the detection pins will have different connection states depending on the input power provided by the power supply 20. Specifically, the SENSE0 and SENSE1 pins of the four detection pins 122 can be connected to the power supply 20, and each can be connected to the ground terminal or the open circuit terminal of the power supply 20. In this way, the microcontroller 14 can determine whether the SENSE0 and SENSE1 pins are in a grounded or open circuit connection state based on the detection signals obtained from the SENSE0 and SENSE1 pins. It should be noted that this disclosure is not limited to this PCIe 5.0 12VHPWR connector, and other types of connectors with detection pins can also be used, and the number of detection pins is not limited to two.

[0029] Please continue to refer to this. Figure 1 In this embodiment, the prompting device 13 may include one or more of a light-emitting diode, a display, and a sound output device. The microcontroller 14 may include one or more processing / control units with data receiving, recording, processing, storage, and output functions. The processing / control unit may be, for example, a processor, a programmable logic controller, or any combination thereof. The microcontroller 14 is connected to the plurality of detection pins and is used to determine an input power provided by the power supply 20 based on a connection status information of the plurality of detection pins and a preset power meter, wherein the preset power meter contains a correspondence between multiple preset connection states and multiple preset power levels.

[0030] Please combine Figure 1 and Figure 2 refer to Figure 3 , Figure 3 This is a flowchart illustrating a display card power consumption monitoring and anomaly warning method according to an embodiment of the present invention. Figure 3As shown, the display card power consumption monitoring and abnormal warning method disclosed herein may include the following steps executed by a microcontroller: Step S11: Obtaining connection status information of multiple detection pins of a power connection terminal on the display card; Step S13: Determining an input power provided by a power supply based on the connection status information and a preset power table, wherein the preset power table contains a correspondence between multiple preset connection states and multiple preset power; Step S15: Determining whether the input power matches a required power of the power element; and Step S17: Triggering at least one prompting device based on the matching result of the input power and the required power.

[0031] In step S11, the microcontroller 14 can obtain connection status information of multiple detection pins 122 of the power connection terminal 12. For example, these detection pins 122 may include SENSE0 and SENSE1 pins, and the connection status information may include information that SENSE0 and SENSE1 pins are each in a grounded state or an open-circuit state. Specifically, the connection status information may include the connection status of SENSE0 and SENSE1 pins respectively connected to the ground terminal or open-circuit terminal of the power supply 20, that is, SENSE0 and SENSE1 pins may be in one of four connection states: "grounded / grounded", "open-circuit / grounded", "grounded / open-circuit", and "open-circuit / open-circuit".

[0032] In step S13, the microcontroller 14 can determine an input power supplied by a power supply based on the connection status information and a preset power table. In one embodiment, the preset power table can be pre-stored in the read-only memory (ROM) of the microcontroller 14. Please refer to Table 2, which shows the correspondence between multiple preset connection states and multiple preset power values ​​contained in the preset power table.

[0033] Table 2:

[0034]

[0035] For example, when the microcontroller 14 detects that the SENSE0 and SENSE1 pins are in a "ground / ground" connection state, it can determine that the power supply 20 provides an input power of 600 watts; when the microcontroller 14 detects that the SENSE0 and SENSE1 pins are in a "open / ground" connection state, it can determine that the power supply 20 provides an input power of 450 watts; when the microcontroller 14 detects that the SENSE0 and SENSE1 pins are in a "ground / open" connection state, it can determine that the power supply 20 provides an input power of 300 watts; and when the microcontroller 14 detects that the SENSE0 and SENSE1 pins are in an "open / open" connection state, it can determine that the power supply 20 provides an input power of 150 watts.

[0036] In step S15, the microcontroller 14 can determine whether the input power matches the power requirement of the power element 110. For example, the power requirement of the power element 110 can be pre-stored in the read-only memory of the microcontroller 14 itself, or the microcontroller 14 can monitor the power requirement of the power element 110 or obtain relevant data from other components; this disclosure does not limit this. Specifically, when the microcontroller 14 determines that the input power provided by the power supply 20 is not lower than the power requirement of the power element 110, it can determine that the input power and the power requirement are matched; conversely, when it determines that the input power provided by the power supply 20 is lower than the power requirement of the power element 110, it can determine that the input power and the power requirement are mismatched. In addition, the microcontroller 14 can also determine the power requirement based on a current state of the power element 110. As shown in Table 2, the initial power requirement of the display card is low when powered on, while the power requirement is high when it reaches a stable and continuous state.

[0037] In step S17, the microcontroller 14 can trigger at least one prompting device 13 based on the matching result of the input power and the required power. In one embodiment, the prompting device 13 may include multiple light-emitting diodes (LEDs) of different colors. When the microcontroller 14 determines that the input power matches the required power, it can trigger an LED of a first color (e.g., green); conversely, when the microcontroller 14 determines that the input power and the required power do not match, it can trigger an LED of a second color (e.g., red). Furthermore, if the computer case is transparent, these LEDs can be directly mounted on the graphics card 11; if the case is opaque, these LEDs can be mounted on the case and connected to the graphics card 11. This allows the user to intuitively understand and continuously monitor the working status of the graphics card.

[0038] In one embodiment, the prompting device 13 may include a display, and when the microcontroller 14 determines that the input power does not match the required power, it can trigger the display to show a warning message to notify the user. Further, if the computer case is transparent, the display can be directly mounted on the graphics card 11; if the case is opaque, the display can be an external screen or mounted on the case and connected to the graphics card 11. In one embodiment, the prompting device 13 may include a sound output device, and when the microcontroller 14 determines that the input power does not match the required power, it can trigger the sound output device to emit a warning sound to notify the user. This sound output device can be directly mounted on the graphics card 110, or mounted externally to the graphics card 110 and connected to the graphics card 11; this disclosure does not limit this. Additionally, the microcontroller 14 can also record power abnormality information in the system log for subsequent viewing and analysis by the user. It should be noted that the various embodiments of the above-mentioned prompting device 13 can be combined with each other. For example, when the microcontroller 14 determines that the input power does not match the required power, it can simultaneously trigger the red light-emitting diode to light up, trigger the display to show a warning message, and trigger the sound output device to emit a warning sound. In this way, this disclosure allows users to intuitively understand and continuously monitor the working status of the graphics card, enabling them to take appropriate measures in a timely manner when the graphics card power consumption is abnormal.

[0039] Through the above structure, the graphics card power consumption monitoring and anomaly warning system and method disclosed in this disclosure obtains connection status information of the detection pin of the graphics card's power connection terminal using a microcontroller. Combined with a preset power table recording the correspondence between multiple preset connection states and multiple preset power levels, it can determine whether the input power provided by the power supply matches the power requirement of the graphics card's power components, and can trigger at least one prompting device based on the matching result. Therefore, this disclosure allows users to intuitively understand and continuously monitor the graphics card's operating status, enabling timely and appropriate handling measures to be taken when the graphics card's power consumption is abnormal.
