ACA1232 - Power consumption.

[bbond007]

So does anyone use these weak PSU's with a similar configuration? Am I worrying too much about it - I guess there's an unlikely chance its 'just enough', or should i hack the end of the a600 psu onto an ATX PSU, or is there another option?

Thanks.

I used my stock A1200 PS with an 030/40 with FPU and 32MB ram, CF card on 4xIDE, subway, PCMCIA wireless and it was all working well. I started having issues on cold boot when I added an Amigamaniac SVIDEO adapter to the mix.

I would suggest getting a A500 PS shell and mounting a micro ATX PS inside...

I have an A-power PS that I mounted inside the stock A1200 PS. I only did that because the rocker switch in the a-power broke. Micro ATX would never fit in a stock A1200 PS. Perhaps it would fit in the A600 unit.

I say to do that just to replace the aged and less efficient components with newer switching style PS.

There's always this:

$32 for a 300-watt PSU with Amiga lead already attached, doesn't seem like a bad deal.  Don't see any reason why you'd have to put it in a desktop case or tower case, just kick it under the desk on the floor, right?  ;-)

I have something like that as well, actually forgot I owned it until I moved. It was sold as "bigfoot" PS. I think it came from Softhut. Anyway, its ok, just ugly and very loud for my otherwise silent A1200. I used very briefly it when I broke the rocker switch on the a-power in my move. The sound was driving me crazy...

You could make the same thing with a micro and it would be a little more attractive at least, but if at least if you start with the micro you have the option of mounting it in the A500 PS chassis.

wth is that, antenna cable? I'll pass no judgement on someone elses work but  it's a bit 'whackier' than what i'd thought of hacking together.

I do like the idea of a USB connector for power...

I could see potential problems with those exposed wires everywhere if you had pets or children... maybe not, i'm no safety expert... Anyway

Too bad Mitch does not make the a-power anymore. You'd really like that.

If you wanted stuff the A600 PS chassis you could always retrobrite it to remove the UV, but I'd probably look into making it black with some sort of plastic paint. The stock A1200 one is black anyway

Sounds like a fun project

isn't there a small low power mains atx power pack for a tiny pc that i could use? one that is low wattage, cheap, requires no active cooling and could be fitted in the chunky a600 brick? wishful thinking i guess;)

I guess they made both colors...

There was someone who mounted a micro ATX(including fan) in A500 brick and the result was quite nice. That is why I suggested it. I had acquired a micro ATX OS from somewhere and after seeing that project I was going to do one of my own but I found that the A1200 PS(my black one) is quite a bit smaller than the A500 one used. I don't know if there is a physical size difference between the A600 and A500 bricks.

I also read an article (perhaps Tomsharware) where someone removed the fans from PC PS and they were still able to operate reliably without a fan. I don't know if this due to the fact that CPU fans provide enough airflow through the case.

I once had a 486 computer that I used to run some satellite equipment. I removed the fan from the PS and ran it that way for years....

My A1200 was a NOS from Amigakit like 3-4 years ago.

Its a 1D4 and I took the MB to do a different MB fix for multiscan artifacts and at that point I inspected to see if I needed the timing fix and it did not. It did not look like those components were ever populated... so not all need timing fixes.

I run with Blizz1260.
