Commodore Amiga 500 full replacement Power Supply

Commodore Amiga 500 replacement Power Supply

Gallery:

This is a full replacement of the power supply of the Amiga 500 with a similar one of the last generation. This type of switching power supply fits perfectly inside the case of the original psu.

The repair will not be made because this psu is very common at very low prices, i don’t waste even a second to find the multiple faults, i prefer devote to other things less common.

    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.

    @Mech

    This is just an example of how you can do, certainly i will not use this power supply 24h switched on.

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

    @Mikrokernel

    Ciao Mikro

    Questo ALIM dato il basso amperaggio non va bene su 1200 carozzati , va benissimo su un 500/600/1200 liscio senza nulla, per la tua situzione ti consiglio di optare per modifiche con ATX, vedi post:
