A4000 PSU to ATX Converter Cable

Use a readily available ATX power supply in your Amiga A4000 or A4000T with this converter cable.

Adapter simply plugs onto a standard ATX Power Supply and into A4000 motherboard.

Adapter cable is fitted with a power on/off switch on a 50cm cable.

Wow, this looks better than the Elbox adapter mess and cheaper

keropi · 17 November 2006, 13:27

better than elbox's one? are you sure? the elbox pcb also has a chip on it...

The chip isn't needed for a standard case, only tower conversions which use an ATX style momentary switch.
Neater than either though is to buy the appropriate plug for the A4000, remove all the spare wires from the ATX PSU, and fit the new plug in place of the ATX connector, remembering to leave the wires for the power switch free so that you can connect them to something (I swapped the power button on my ATX case with a turbo button from an old AT machine, and fitted a little plug to the end of the power wires to make removal of the PSU easy)

Hi

Ive got one of these, brand new i bought off a friend. My 4000D power supply still works, but im having some stability issues so i thought ill try this adaptor out. But the amiga wont boot, just grey screen with atx and adaptor. Tried 2 atx power supplies now one 185w and the other 450w. Go back the original 4000D power supply and it will boot.

Measured the voltages on the end of the adaptor and everything is in the right place.

Any ideas?

Check that the molex pins where they go into the A4000 board, sometimes one will push back up inside the connector. The solution is to pull the pin back out and move the little side fins out a bit before pushing it back in place.

That looks good there is no movement

zharn · 11 December 2013, 12:35

just measured the voltages on a zorro slot

atx psu - 4.7 and 12.67

4000d psu - 4.91 and 11.82

ill try a couple more psu tomorrow

Ok tried 3 atx power supplies now, even took the 4000D board out and measured the voltages on the underside of the motherboard just to make sure its making contact and it is

loaded up the power supply with 3 hard drives still nothing (dark gray screen caps lock lights up they off)

connected all the 5v rails on the motherboard connector (like i have to do with 1200 to make the power supply stay on) - nothing (dark gray screen caps lock lights up they off)

plug in original power supply and it works

Im out of ideas, putting it back together

zharn · 12 December 2013, 10:06

how can i simulate power good?, can you simply put a 5v line on it?

zharn · 15 December 2013, 02:22

Was was my dads yesterday, so i reclaimed an atx supply he wasnt using and it works on the 4000D? So ive taken photos of all the supplies ive tested and posted a .rar file in the zone. Can someone tell me why the (20131215_111058_works.jpg) only works?
