on an other forum an apple guy claims the apple imac power supply does not out put 5 volts to the M/B
I find that hard to believe as every PC M/B has 6 separate 5 volt line coming in from the P/S
any body know for sure if apple imac mid 11 21.5 has NO 5volt line out from the P/S to the M/B
the guy said the M/B takes in 12 volts and converts that down to 5 volts for sata usb ect on the M/B not the P/S
unlike a PC but like a laptop that has 12 volt power in from the battery
any body know or have a mid 11 imac P/S pin out both at the P/S and at the M/B end of the main power connectors ?
or know if a delayed or separate signal is needed to get the 5 volt power up and running ?
