So I had to work out how to use a Power supply Voltech 240V-12V (23A) 13.8V Output to power the HP board, so a bit of research and AI, I came up with using a 12V to 19V 10A 190W DC-DC Boost Step Up Power Converter Voltage Regulator Module and a 7.4x5.0mm DC Tip Plug Round Connector Laptop Power Cable For HP / for Dell N with two resistors one a 220k and the other a 120k.
The mother board now powers up and runs this web site as you are reading, yes the whole site runs off this mother board, its a i7 with 12G memory and runs on Ubuntu 26.04, will post a image of the mother board soon.
