Powering a Colecvision with an Arcade Style Switching Power Supply

[Timmy Two-Step]

Theoretically, is it possible to power (at least temporarily for testing purposes) an old Colecovision with one of those switching power supplies that are used inside arcade cabinets.....

(you can get them on Amazon for $25-35).   Appears to have the +12v, +5v and -5v needed for coleco operation.    Why couldn't I just wire it up to the connections on the colecovision?

Any amperage issues?   I don't want to blow anything out.

 

I am 99% sure my power supply is failing as I get varied results when I direct test the plug itself on the 12v line specifically .....

I'd be concerned about the electrical noise those cheap supplies put out. There have been multiple attempts at adapting similar supplies in the past with mixed results.

 

I would personally recommend one of two solutions. First, the colusb, but I'm pretty sure it isn't in stock (and hasn't been for quite some time). The other one is a 2 piece solution. This adapter:

and the matching meanwell psu brick (from a reputable dealer like Digikey or mouser). It's probably going to run around $60-70 all together with shipping. But it's been tested by multiple people to be noise free.

 

A company called Keelog also makes one. It seems to be solid, but the cable is a little short, and some of the soldering inside may be questionable from what I have read here on AA. But it does use a reputable meanwell supply inside.
