Hi.. just to give some report about this mod..
I followed Chinese Website guide ( I was unable to open all files but I figured out what is needed to be soldered on motherboard)
I did modification but without success about stepping down voltage.. everything is placed as explained and Maschine boots.
2 resistors and one relay .. but voltage on PCI slot is still 20 v ( adapter is 20 v)
It gave me idea to pull out PCI pins that conduct power and add ,,voltage step Buck '' in between to lower voltage to 12 v. (But I believe that this will take a lot of time )
I also have to report that I found none of points, that shows me 12 v on voltmeter
So I am not sure if that voltage even exists on this slim motherboard because none of components use 12 v to operate. Voltage on board is mostly about 1.4v 3.3v; 5.1v
Maybe something else is needed to be added on board but as I said I was not able to open all files.
