CSPS-ATX12VO V2

Overview

Huawei/HP 460W/750W/1200W server CSPS redundant power supply adapter ATX12VO standard module board/power cage. It leads to standard PS-ON, PWR-OK, and 12VSB, and the line sequence and level comply with the ATX12VO standard. Output one 10pin motherboard socket of atx12vo, three-way XT60 interface CPU or graphics card 12v, can support dual CPU + one graphics card or 1U + dual cards. Each xt60 socket can support a maximum of 12v30a@360W continuous output (without exceeding the power limit) ).
At the same time, the module board reserves a switch that can switch between ATX mode and forced on mode. In the forced on mode, the output is turned on directly regardless of the pson signal, and can be used as an ordinary 12v switching power supply.
Can be used with atx12vo to convert old atx24pin, link: https://oshwhub.com/sinonzxc/atx12vo-24pin
Thanks: Mr. Mo Yanluoxian helped me with proofing and verification
