Amiga 4000 SFX power supply adapter package

thingiverse

My sister recently acquired an Amiga 4000D with no power supply or any support hardware to suit. I printed some of the other available Amiga 4000D SFX adapters and wasn't quite happy with the rigidity or complexity of the whole package. Now the 4000 was a whacko machine with its ridiculous big relay rod running down the side to the power supply, which seemed superfluous to replicate... so I designed my own. The button is from mwieland's excellent power button relay rod set - if it ain't broke etc! The bracket itself is a bit thicker than other models I've and is designed with holes to save material where appropriate and slightly thinner in two spots on the front to allow the 4000's PSU hooks to function. The pattern matches common SFX power supplies (I'm using a Silverstone 450W) and allows the bracket to be bolted into place rather than resting under the supply, improving overall rigidity. The switch support bracket picks up on the two 5.25" holes and assumes the use of a CDROM drive or other 5.25" device in the top bay for support. It utilizes a cheap pushbutton toggle switch (Jaycar SP0718) which should be available cheaply from most electronics suppliers. The short relay rod is designed to work with mweiland's button and fits neatly between the switch and button. I retain it with a tiny bit of black tape to make a friction fit between the rod and button and some double sided tape to stop the rod rattling against the switch. You'll still need some form of ATX to A4000 adapter or to modify the power supply wiring to suit - if you're going that route, the 4000's PSU connector is a TE Mate'n'Lock type setup, the pins can be removed with a standard Molex pin remover and are TE part number 926894-1. Guides on building such adapters are available all over the place, I personally refer to the work of Ian Stedman. Hope somebody finds this as useful as I do!
