do someone know the Voltage of the output from power suply (black = 0, grau = 12V ? , brown = ? )
and the output from the DC - DC board?
Thanx

Hi, this URL mainly covers the repair of capacitors but if you scan down to page 13 there is a pinout of power supply connections. Hope this helps. Ralph

forget the power supply right now, check the dc/dc board, if you don't have the proper voltages there then ck the power supply.
looking straight into the dc/dc female plug...
onA - Grd-12vR -(?) -5.0vR -3.3vR
(?) - 12v - 12v - 5.0v - onB - 3.3v
the ? pins are probably grounds as well, but I'm not 100% sure - the 'R' voltages are only on when the power A and B pins are touched together ie. the computer is on

Hi, Thanx for help, but this is not the power supply of the model A1144, it's from the other G5-Model (A1058), I could not find anything about the A1144 on this page.

I was hoping the color id's for the different voltages would help you identify your supply voltages. Usually they use the same color codes.Good luck with your problem. Ralph
