I have recently bought three bare motherboards with the memory boards, but unfortunately, but unfortunately, they have proprietary power supply connectors. Custom 10 pin and a 20pin, that fits a standard ATX PSU.
I kinda hope, that I might be able to splice something from an standard ATX PSU, but I don't have the pinout.
I did some continuity measuring with a multimeter and came up with this:
G is ground, numbers have continuity between each other, ie. 1 to 1 and 2 to 2.
I don't know, what the blanks are, or at least, I don't know where to measure them.
The 10pin looks completely custom, but the 20 pin might just be a standard ATX pinout, if flipped horizontally.
If that is true, that means, that 1 is +5V and 2 is +3.3V.
It could also mean, that the CPUs and maybe even the RAM is running mainly from the 3.3V, which could make using a modern PSU a bit complicated.
Is an adapter like this a viable option, or am I stuck searching for a custom PSU?
