#8 pin voltage
The #8 pin voltage is always zero. Can this only be caused a bad power supply?
#9 pin 4.94vdc #14 pin 4.02vdc then drops to zero when comp is switched on. Dell 9150 with flashing yellow light. |

Re: #8 pin voltage
Check out the sticky, very good explanation.
Test your power supply with a multi meter

Re: #8 pin voltage
Well, assuming that your testing by the procedure in the sticky, then what you're measuring is the power good signal sent from the psu. If it doesn't send enough of a signal, the computer will not start. Try another psu to make sure, but sounds like that's what's needed.
