Description of design direction:

In order to cope with the impact of the next mining wave, I received Congliang's 3060 or better mining card for ￥599. I only have a 500W power supply at home. Of course, I must prepare a cheap and large server power supply that has been tested in the battlefield for many years, so I made this ALL IN BOOM ONE's adapter board is affordable, suitable for home use, and has sufficient interfaces. (Please do not use it on a computer with important information, there may be a boom at any time!!!, this is what picking up garbage is like, since you want to pursue excitement, you must follow through to the end).

Interface Description:

The line sequence should be (not verified!!!) the line sequence of Great Wall, which leads to three 8pins (CPU/GPU), two 5pins (converted to SATA power supply or large 4D interface power supply), a 24pin motherboard interface, and There is an XT60 interface. (Looking at the specifications, the XT60 seems to be able to exceed 30A for a long time, but some people say that it is fine even if it exceeds 60A for a long time. It has not been verified!!) It is suitable for low-power home use.

Component Description:

Both the 5v and 3.3v dcdc modules use the 1.5 yuan disassembled zxdn10. Compared with the 3~4A output of the kcores original mini560 (about 95% efficiency) module, the zxdn directly reaches 10A, which is quite enough, and 12A provides output protection. . The normal load efficiency is basically above 92%. Huawei's PW22A is also very powerful (but a bit more expensive). The 5V output can reach 25A, and the low load efficiency is also above 90% (data source: blog.iccfish.com Second-hand DC non-isolated step-down module>). But household equipment (5v and 3.3v) should not require such a large current. 
Keywords for connector purchase: 5557/5569; Vout = 0.591 The one is relatively large because my hands are shaky; most places that require excessive current are windowed, and remember to insulate them after adding solder.

Updated to V1.2 on May 25, 2022

The problem of reverse placement of ZXDN10 in the V1.1 version has been fixed, and many meaningless solder mask openings have been removed. The package of the CSPS connector has been updated to better fit the WINGTAT connector.
