I have just completed this mod with the above PSU.

@Rave

Hi,

Which model RT-50 did you use? Can it also be use on the A1200 model?

Thanks

Howard

Rogue ProgramsThese days, the Internet is flooded with a range of maiulcois programs such as spyware, adware and Trojans. These gain access to your computer through loopholes in application software or in the operating system. To eliminate these programs and fix your computer, scan with a compatible anti-virus program. Registry ErrorsThe Windows Registry holds information regarding hardware and software settings on your computer. If a maiulcois program corrupts the Registry, it may result in a blue screen error.These problems could be fixed either manually, by editing the Registry directly, or with third-party software that can check and repair a corrupted Registry. Always back up the Registry before attempting to edit it.

Why use a power supply that is weaker than a A500 psu originally was.. +5v was 4.5amp on A500psu and +5v is what is important. You are in effect making it as weak as A600/1200 psu. While it will work for most machines, heavily expanded ones may have problems.

Another thing to consider is many of these caged psu’s were designed to be in a fanned enclosure,and although the 500 might only push the specs,this should be considered. The data sheet should indicate if a fan is needed.

Mean well makes some terrible psu’s(not all). Many have high ripple and some come with poor quality caps. As usual check the datasheet.

I hope this doesn’t come off as negative,i just want to point out the facts to users.

Ma saresti in grado di farne uno per un A1200 che monta PPC e Bvision?

Esiste qualche dettaglio in più di questo progetto?

A bit late to the party… I have RT-50B that I’m trying to use in a project with one loose A500 motherboard. It works and powers it up fine, but I have slight waves going across my monitor that I don’t have when using normal Amiga PSU, aka noise. Is it possible to get rid of it, or that’s just how it goes when using these kinds of PSUs?

Excellent job with the pictures. One question though, what did you do with the large black cable (in IMG_1402 & 1406?) I.e, the one which comes out together with the five connectors on the left/DC-side (and was soldered onto the other side on the original PSU)? I can’t see where it goes, and it’s not hooked up to any of the terminals on the new PSU, AFAIKT. (It disappears in the rightmost corner of pic IMG_1402 – http://www.nightfallcrew.com/wp-content/gallery/commodore-amiga-500-replacement-power-supply/thumbs/thumbs_IMG_1402.jpg

Thanks again for documenting this. Guessing a lot of Amiga owners are going to replace their ailing with a new Meanwell PSU.

Thanks for clarifying that @Dave. I guess I’ll just cut off (& terminate) that cable then. I was thinking of hooking it up to ground (based on suggestions from others), but not sure if there’s any real benefit in this.

btw-it’s funny how all the pics and the videos (that I’ve seen so far) omit this little information as that cable is quite prominent. :)

Cheers,

Martin
