Individual Computer's new PSU
I see you can now pre-order icomp's new dedicated Amiga PSU called the "CA-PSU" for A500, A600 & A1200. It's rated at 50W with a few interesting features like "cable drop compensation" but is fairly pricy too.
https://icomp.de/shop-icomp/en/shop/...mpact_200-240V Are existing Pico & Meanwell PSUs not reliable enough compared to this? |

I’ve been waiting to see what he designed as a psu replacement and I’m somewhat disappointed. That two brick design is straight up ugly looking. And I’m not a fan of having two anyways. Seems to me there could be a better way to implement it.

Wow. What a terrible product. Poorly designed, overpriced, and just simply ugly.

Edit: I do like the fact that the DC part is in what's basically a C64 cartridge shell! |

I think the bulk of the cost is going towards the custom CA-PSU converter rather than the off the shelf PSU brick, it makes me wonder though if we could attach any easily available PSU brick to this and make it work?

How can a power supply look ugly?
Next to this the inner values are important to have a stable AMIGA. |

@bippym sure it looks a bit rubbish, but I’m wondering how Hewitson can comment that it’s “poorly designed” and a “terrible product”?

"It's ugly"
I don't know about anyone else but I'm fussy about cable management, so don't keep any of my commodore power supplies on display. I recently got an uprated power supply for my CD32, Elsat Pro module, TF330 combo, and for some reason the pro module hates it so had to revert back to the original supply. I don't mind paying extra for something that is high quality and delivers. |

And according to the description... " It is the first power supply on the market that fully complies with the original Commodore specifications". So the price is not great but for a niche product we will never get mainstream prices. And iComp are rarely the cheapest option. AmigaStore.eu has a couple of replacement models already, starting at €55. Don't know anything about the build quality etc of those, but on paper they look like a better deal, especially if you want single brick design. At one point I was in contact with Ray Carlsen and while I was ok with his asking price, the whole thing with shipping from US + taxes, import charges, VAT would land at 3 times the price of this one, so local availability is another factor of course... |

I have seen a video where Jens talks about power supplies. Several are tested. True, the Mean Well units have higher ripple than the Amiga originally specified (but so do pretty much all of the supplies tested). How do we know that the low ripple specified by Commodore engineers was actually required? What incredibly sensitive component is on an Amiga that requires such low ripple?
I doubt very much that the Individual Computers supplies are poorly designed. More likely they are over designed and for that reason are too expensive. They fix a problem (excessive ripple) that I don't think exists. My Amiga certainly worked for a long time with a power supply that was far out of spec with its dodgy old capacitors, then it was replaced with a Mean Well and has performed flawlessly since. Aesthetically I hate the two-box solution but that's just a personal opinion. On the plus side you do get the power switch up where you can reach it. |

It should be noted too that ripple specifications are generally stated for maximum load, and that the ripple is lower when the PSU isn't operating at its peak. Given that most Amiga setups don't even max out the original PSUs' specified capacities, let alone a modern Meanwell, it can be assumed that the normal-use ripple from a Meanwell-based PSU will be lower than the specification given in the datasheets, because a typical Amiga setup is likely much lower than the PSU's rating. My tests on a very small sample of PSUs would indicate that this is the case anyway. Of course, heavy consumers like 040+ or PPC cards are a different story... |

I would guess, that a seizable portion of the price goes to the insurance company:
"CA-PSU is covered by a German product liability insurance." |

Honestly this looks like a great product. Off-the-shelf AC brick, then a custom power conditioner. Yeah it's an extra box but if it delivers best-in-class power, that's worth it.

Looks inconvenient with the cables going from the same direction into the C64 cart. Fine if you never go to demo parties with your amiga, annoying if your machine is regularly on the move. :-) Just thinking about the use case when packing up and tying your cables neatly.
Let's see once people start getting theirs. |

I think this looks a bit crappy, but it seems to have some practical reasons behind it for that.
The price is not much higher than what the competition asks for. And my experiences with Jens' products have been outstanding so far. If you are travelling to retro exhibitions with your Amiga a bit, or like visiting your friends place, the large CBM power brick is always kind of an unconvenience if you just want to have everything in one backpack. This would solve this problem for me. |

Lots of the competitors in this space don't even have a power switch

I would have loved the power switch to be near (or in) the connector at the Computer.
