[0002] CRPS power supplies are designed to provide redundant power support and fault recovery capabilities for server systems. They ensure server availability, reliability, and continuity, reducing system downtime and the risk of data loss. ATX power supplies primarily convert 220V AC power from the power outlet to DC power for internal PC use, supplying power to the motherboard through various interfaces. Currently, CRPS-to-ATX power supply backplanes on the market are mainly used for rack server power supply designs. They typically only have two CRPS slots and corresponding ATX standard power output interfaces, supporting only a fixed power redundancy mode. They cannot flexibly adjust the power redundancy configuration according to actual needs. When a power supply fails or has an abnormal connection, it can easily cause the motherboard to lose power, affecting its normal operation and making it difficult to meet the needs of more application scenarios.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1: This embodiment of the present invention provides a four-channel CRPS to ATX power supply backplane, such as... Figure 1 and Figure 2 As shown, the four-way CRPS to ATX power supply backplane is configured with 3+1 or 2+2 power redundancy. The four-way CRPS to ATX power supply backplane includes: a CRPS power board 1; four CRPS power sockets 2, all connected to the CRPS power board 1, and each for connecting a PSU power supply 3; wherein each CRPS power socket 2 is assigned a physical address; at least one ATX power board 4, all connected to the CRPS power board 1, and each for connecting a motherboard 5 to provide power outputs for P12V, PSV_STBY, P5V, and P3V3.

[0029] Furthermore, in this embodiment, the CRPS power board 1 establishes a connection with four CRPS power sockets 2 via a first I2C bus, and with at least one ATX power board 4 via a second I2C bus. Since each CRPS power socket 2 is assigned a physical address, I2C polling scanning can be implemented to locate the address bit.

[0030] Specifically, the CRPS power board 1 includes a backplane chip used to control the load balancing of the power supplies. For example, when one or two power supplies fail or experience contact problems, another working power supply can immediately take over their operation. After replacing the power supply, all four power supplies work together again, thus achieving load balancing. The four PSU power supplies 3 are identical. It should be noted that this embodiment does not specifically limit the model of the backplane chip; the actual application should be considered.

[0031] Furthermore, in this embodiment, the ATX power board 4 includes a power control chip, which controls the power output of P12V, PSV_STBY, P5V, and P3V3. The power control chip is model TPS53819.

[0032] By combining the backplane chip of CRPS power board 1 with the power control chip of ATX power board 4, not only can power input control be effectively realized, but it is also convenient to repair in time when a fault occurs. This effectively solves the problem of the difficulty in repair when a fault occurs due to the integration of power input control on the motherboard in the existing technology, as well as the problem of defaulting to low power output when the connected CRPS power supply has different power.

[0033] Specifically, the ATX power supply board 4 also includes an IPMI protocol communication interface. The motherboard 5 establishes a communication connection with the IPMI protocol communication interface through the I2C hardware interface, thereby enabling the motherboard 5 to monitor the parameters and status of each power supply, such as output voltage, current, and error status.

[0034] Specifically, the ATX power board 4 also includes a 24-pin power connector, an 8-pin power connector, a PCIe 12VHPWR power connector, and a SATA hard drive power connector, all of which meet the ATX 3.1 design specification. In practical applications, connections are established with the corresponding power connectors via one 24-pin main power connector, three 8-pin 12V power connectors, one PCIe 12VHPWR auxiliary power connector, and two SATA hard drive power connectors.

[0035] In this embodiment, there are four ATX power supply boards 4, each connected to a CRPS power supply board 1 and each connected to a motherboard 5. Therefore, the four-channel CRPS to ATX power supply backplane in this embodiment supports the simultaneous operation of four motherboards 5. When one of the PSU power supplies 3 is removed during operation, the motherboard 5 whose power supply is removed will perform address addressing through the IPMI protocol communication interface provided by the corresponding ATX power supply board 4 and report the anomaly through the BMC so as to adjust the power load in a timely manner.

[0036] Furthermore, in this embodiment, the PSU power supply 3 includes a PRSNT pin, and the CRPS power board 1 obtains the connection status of the PSU power supply 3 by detecting the PRSNT pin. The four-channel CRPS to ATX power supply backplane in this embodiment also includes an alarm device for triggering an alarm when the number of connected PSU power supplies 3 is less than four. In addition, in practical applications, alarms can be triggered based on the actual status of the PSU power supply 3 through multi-dimensional alarm conditions, such as triggering alarms based on abnormalities in the temperature, voltage, or current of the PSU power supply 3, ensuring that the server system can promptly alert when abnormalities occur in the PSU power supply 3.

[0037] Specifically, the alarm device includes at least one of a buzzer alarm module, an indicator light alarm module, and a remote alarm module, supporting diverse alarm methods to ensure users can promptly issue alarm signals in different environments. The buzzer alarm module, indicator light alarm module, and remote alarm module can be installed in any suitable location. For example, if fewer than four PSU power supplies are connected, the buzzer alarm module will be triggered, and power will be cut off.

[0038] This utility model's four-channel CRPS to ATX power supply backplane supports 3+1 or 2+2 power redundancy designs, making it applicable to various scenarios such as cloud gaming, cloud rendering, and cloud computing. It accommodates higher power and efficiency power supplies, and the power channels of this backplane are highly compatible with the PCB material, facilitating maintenance. In practical applications, it meets the requirements of real-time monitoring and adjustment mechanisms, dynamically adjusting load distribution based on actual performance and load demands, according to parameters such as the power supply's actual output power and temperature, thereby optimizing the distribution and improving load balancing accuracy.

[0039] Example 2: This embodiment of the present invention also provides a server, which includes the four-channel CRPS to ATX power supply backplane provided in Example 1. The description of the four-channel CRPS to ATX power supply backplane is provided in Example 1 and will not be repeated here.

[0040] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
