i haven't read the entire thread, but as well as the voltages to wire up, wasn't there a "power good" cable (green? grey) that had to be wired up as well? i know there was an extra ATX cable that needed wiring up, over the wiring it up for the A1200.

Sorry if this has been mentioned.

There is a PWR-ON wire that needs to be shorted to ground for the PSU to start, but this is connected to the spades on the AmigaKit adapter so it is wired to the power switch.
Modern PSUs have a sense wire that needs to be connected to the supply as well. This can be seen on the ATX connector - if there are two wires going into the same pin, then those two wires should be reconnected if you cut off the connector. I wired up an ATX PSU for my A2000 yesterday and it had a sense wire on the 3.3V supply. Although the A2000 is not using the 3.3V supply, I still had to connect the sense wire to a 3.3V supply wire or the PSU would not work.

yeah. that.

i use a NOS Dell SFF PSU, it's small, and only rated at 170W, but that's plenty for the Amiga, and i don't need to worry about minimum load.

hope it gets sorted anyway.
