Question about using ATX PSU for DC Power

tech3475

Hi, my apologies if this is the wrong place to ask but it seemed like it made the most sense.

 

In a few months I'm going to be putting my Amiga 1200 into a new case and power it using an ATX PSU, one thing I'd also like to do as part of this project is to internalize the scan doubler I use at the same time and power it using the ATX PSU.

 

The Scan Doubler in question is a GBS-8220, according to the manual (link: https://www.mikesarcade.com/estore/datasheets/GBS-8200-booklet.pdf), it can take 5V 2A but the issue I have is how to power it safely.

 

The original idea was just to solder it to a molex connector on the 5V rail and power it directly, but I'm concerned over whether this is safe without some kind of protection in place (I've seen resistors used for example or a fuse for similar purposes).

 

The other idea is to get some kind of circuit regulator and possibly use the 12V rail, stepping down to 5V.

 

Any advice is appreciated.

 

Thank you.

  • I should give more details.

     

    The Amiga mobo is going to be put in a new case and powered by the PSU using the standard motherboard connector via an adapter I’m buying.

     

    The Scan Doubler I plan on powering through the molex connector you’d typically use for disk drives using a spare molex plug I have. So in the case of say that adapter I mentioned earlier, it would be used only for the Scan Doubler and nothing else.

     

    I already have an external DC adapter for the scan doubler but I’m trying to internalise it if possible.

    powered by the PSU

    Is this the ATX PSU you are looking at using?

     

    I think some pictures of what you have would help the E14 community to make better suggestions.

     

    ps: glad to see the Amiga is still being used. In my opinion the Amiga and Atari 1040ST were great computers that brought low-cost processing up to another level; appealing to both professional and gaming users.
