I am trying to upgrade my Amiga 4000 power supply with a Corsair sx450 and the Amigakit adapter. When I connect it, my 4000 does not power on. The fan spins for like one second and then nothing. The original power supply works perfectly and the 4000 works perfectly.
Also I can take the new power supply and connect it with an adapter to an Amiga 500 and the 500 boots fine which leads me to believe that the new PSU is good.
I have tried connecting the floppy drive and DOM to the new PSU when it is connected to the 4000 with no change.
Can anyone tell me what I am missing here?
