Title: PSU for Amiga 1200
Post by: Skunkfish on 14:33, 07 April 21
I did consider posting this in some Amiga forums, but that would involve signing up and dealing with all of the bickering....

I picked up an Astec AA21430 for pittance a little while ago, which I'm hoping to use to replace my aging A1200 PSU in a nice 3D printed case.
(PSU is this model: http://www.azsurplus.com/index.php?main_page=product_info&cPath=43_44&products_id=3946)

Ideally I'd like to replace the AT-style power connector with some sort of DIN socket for power, and knock up a cable with a plug for that on one and and the 5-pin square power connector for the Amiga at the other...

Keeping in mind the current required for the Amiga and wanting to avoid any voltage drop due to the Amiga's sensitivity, can anyone suggest a suitable socket/plug for this?

Would this be any good? https://uk.rs-online.com/web/p/dc-power-connectors/6677287

Every connection is a potential failure point. I'd connect an original Amiga power cable directly to the PSU.

Ah, so you've seen my soldering skills?!  ;D


Point taken, although I wasn't planning on sacrificing the original PSU for the cable....

Sure, I could just buy one ready to go - but where's the fun in that?

And where are you going to get an Amiga 5pin square plug without using an original?

If you like CISCO power supply, you should have buy this one for less : https://www.consolekabels.be/a-54163779/voedingen/amiga-500-500-600-1200-aftermarket-voeding/#description (https://www.consolekabels.be/a-54163779/voedingen/amiga-500-500-600-1200-aftermarket-voeding/#description)

Somebody out there's been churning out some new ones for a couple of years now, I think the quality is supposed to be reasonable as well....

The link wasn't the one that I purchased, there's a seller on eBay selling dozens of the things for £5.45 each (inc delivery): https://www.ebay.co.uk/itm/192940058212
