[* black] Voltages are all measured with PIN 1 as reference.
[* black] Pin 5 is the PSU enable line - Logic board pulls this line low (0V) to enable PSU
[* black] Pin 4 voltage varies and is inversely proportional to PSU temperature. Higher Temp = Lower voltage. My measurement was taken at around 24**24 Deg Celsius.
