[0028] In the current server test environment, the power integrity verification of various external devices is a crucial step to ensure the stable operation of the system. Traditional testing methods rely on directly plugging external devices into the corresponding interfaces of the server motherboard. However, this method is restricted by the complexity of the motherboard's physical layout and interface compatibility, resulting in a cumbersome and inefficient testing process. Therefore, the inventor has proposed the following improvement solutions through research, which will be described below.

[0029] Please refer to Figure 1 , an embodiment of the present utility model discloses a computer peripheral power test fixture, which includes: a circuit board 10, on which there are multiple peripheral connection interfaces of different standards, and the peripheral connection interfaces are used to connect external devices of corresponding standards. There is also a power input interface 30 on the circuit board 10, and the power input interface 30 is used to connect an external power supply to supply power to the peripheral connection interfaces. It can be understood that by setting multiple peripheral connection interfaces of different standards in this embodiment, it is possible to support the connection of a variety of external devices with different standard interfaces, meeting different test requirements. Moreover, the computer peripheral power test fixture of this embodiment works independently of the motherboard, reducing the interference of other system components and improving the accuracy and reliability of the test.

[0030] Furthermore, the peripheral connection interfaces include one or more of the RDIMM DDR5 standard interface 20, SODIMM DDR5 standard interface 21, CAMM DDR5 standard interface 22, UDIMM DDR5 standard interface 23, E3.S2C standard interface 24, PCIE5.0 standard interface 25, and OCP3.0 standard interface 26. It can be understood that the RDIMM DDR5 standard interface 20, SODIMM DDR5 standard interface 21, CAMM DDR5 standard interface 22, UDIMM DDR5 standard interface 23, E3.S2C standard interface 24, PCIE5.0 standard interface 25, and OCP3.0 standard interface 26 are applicable to most external devices in the prior art. For example, the RDIMM DDR5 standard interface 20 is applicable to server DDR5 memory modules, the SODIMM DDR5 standard interface 21 and CAMM DDR5 standard interface 22 are applicable to PC DDR5 memory modules, the UDIMM DDR5 standard interface 23 is applicable to desktop DDR5 memory modules, the E3.S2C standard interface 24 is applicable to E3.S CXL memory disks, E3.S hard disks, and E1.S hard disks, the PCIE5.0 standard interface 25 is applicable to network cards and RAID cards, and the OCP3.0 standard interface 26 is applicable to OCP cards.

[0031] Furthermore, in computer devices, especially in high-speed and low-power storage devices and interface standards, a 3.3V voltage is a common power supply requirement. To ensure that the test fixture can be compatible and stably supply power to these devices, a 3.3V conversion chip 40 is also provided on the circuit board 10 of this embodiment. The 3.3V conversion chip 40 is electrically connected between the power input interface 30 and the peripheral connection interface, and is used to convert the electrical energy input by the power input interface 30 into 3.3V electrical energy for output. By integrating the 3.3V conversion chip 40, the test fixture of this embodiment can stably supply electrical energy to external devices that require 3.3V power supply, solving the problem of voltage mismatch. It should be noted that the 3.3V conversion chip 40 and the voltage conversion circuit belong to the prior art and will not be elaborated here.

[0032] Specifically, since the external devices connected to the RDIMM DDR5 standard interface 20, E3.S2C standard interface 24, PCIE5.0 standard interface 25, and OCP3.0 standard interface 26 usually require an input of 3.3V electrical energy, therefore, the 3.3V conversion chip 40 in this embodiment is electrically connected to the RDIMM DDR5 standard interface 20, E3.S2C standard interface 24, PCIE5.0 standard interface 25, and OCP3.0 standard interface 26 respectively, so as to provide 3.3V electrical energy for them when powered on.

[0033] Furthermore, a 3.3V power output interface 60 is also provided on the circuit board 10. The 3.3V power output interface 60 is electrically connected to the 3.3V conversion chip 40 and is used to connect a cable and provide 3.3V output electrical energy for it. It should be noted that although there are already various different standard peripheral connection interfaces on the above-mentioned test fixture, there are still some external devices that cannot be adapted. Therefore, for these external devices, the 3.3V power output interface 60 proposed in this embodiment can be used. One end of the cable is connected to the 3.3V power output interface 60, and the other end is connected to the power input interface 30 of the external device to supply power to it through the 3.3V power output interface 60.

[0035] Specifically, since the external devices connected to the SODIMM DDR5 standard interface 21, the CAMM DDR5 standard interface 22, and the UDIMM DDR5 standard interface 23 usually require an input of 5V electrical energy, the 5V conversion chip 50 in this embodiment is electrically connected to the SODIMM DDR5 standard interface 21, the CAMM DDR5 standard interface 22, and the UDIMM DDR5 standard interface 23 respectively to provide 5V electrical energy for them when powered on.

The 5V power output interface 70 is electrically connected to the 5V conversion chip 50 and is used to connect a cable and provide 5V output electrical energy for it. It should be noted that although there are various different standard peripheral connection interfaces on the above test fixture, there are still some external devices that cannot be adapted. Therefore, for these external devices, the 5V power output interface 70 proposed in this embodiment can be used. One end of the cable is connected to the 5V power output interface 70, and the other end is connected to the power input interface 30 of the external device to supply power to it through the 5V power output interface 70.

[0037] Specifically, since the external devices connected to the RDIMM DDR5 standard interface 20, the E3.S2C standard interface 24, the PCIE5.0 standard interface 25, and the OCP3.0 standard interface 26 usually also require an input of 12V electrical energy, the power input interface 30 in this embodiment is a 12V input interface. The power input interface 30 is electrically connected to the RDIMM DDR5 standard interface 20, the E3.S2C standard interface 24, the PCIE5.0 standard interface 25, and the OCP3.0 standard interface 26 respectively to provide 12V electrical energy for them when powered on. Furthermore, the above 3.3V conversion chip 40 is used to convert the input 12V electrical energy into 3.3V output electrical energy, and the 5V conversion chip 50 is used to convert the input 12V electrical energy into 5V output electrical energy.

[0038] In one embodiment, the circuit board 10 is a rectangular circuit board 10. The peripheral connection interfaces are provided in the middle of the board surface of the rectangular circuit board 10.
