Amiga 4000 power supply
« on: December 10, 2013, 02:01:29 PM »
I was taking another look at my broken A4000 and decided to check power supply voltages.  It is currently putting out 4.45v, 10.32v and -10.67v.  Is this adequate to power my A4000 or are the voltages too weak?  I am getting that rhythmically flashing green screen.

Power supplies can measure different voltages with different cards but the measured looks bad.

I took these measurements with nothing in the case except the motherboard and power supply. I wanted just enough load on the power supply for it to power up.
