Just wondering whether the standard power supply boxed with the CD32 was rated the same as the A1200 one or was it higher like an A500 one? Can't see any reason for it not to be same as A1200 but just curious!
-
they are the same
-
never checked really , but i do run an cd32 with sx-1 and 8mb fast , 20gb hardrive and a FMV without problems..
-
My CD32 PSU is 23W, whereas my A1200 PSU is 25W. I also have an A500 PSU rated at 60W, which I have converted for use with my CD32 + SX32-Pro combo.

?
I plugged my A500 PSU on my A1200 and vice versa, and no problem.

If you have a FMV card, then you only have 4megs not 8. :-)
I am however wondering how did you get the 20gig formatted and paritioned as I am currently trying to format a 40gig I just bought and having major problems. OS3.5 or 3.9 won' t boot off of it, telling me something about a resource.library. OS3.1 boots fine you then I cant get any software on the work partition without it telling me there is a checksum error.

oops forgot to mention I am running a CD32/SX-1 with FMV and 8meg (4when FMV installed) also tried the 40gig on my CD32/SX32 128mb 68030 50mhz. still the same problems. I tried installi stuff from a CD but the CD refuses o boot, even one of those CU AMIGA cd's

How do you Dual Boot? DId you make 2 boot partitions? like HD0 and DH0? I did this but OS3.5 or 3.9 wont boot.

@ lempkee
I had to use a bigfoot supply to get my (almost identical) setup going. The CD32 supply wasn't enough (very crash prone, distorted RGB output).
On second thought, that might have been a C64 supply. Well, it was enough for the CD32+FMV, at least :-D
I wonder where my real CD32 psu is...

My original CD32 power supply can handle My CD32 wih SX32 pro 50Mhz with 50Mhz FPU 128Mb ram and 2.1gb HD, with DSS 8+,SuperGenSX, Floppy drive and SCALA Echo all connected at once, not to mention................ internal fan, without a single problem...............I have had multiple SX32's and an SX-1............the problem isnt the power supply.......it is the backplate of the SX32 and how certain ones seem to suck more power or disriute power differently.........I tried 3 or 4 of them and this is the case..........on the ones that wouldnt work..I tried more power.....and then they worked.
my SX-1 with internal fan and FMV card and withall attachments works fine also,............interestingly adding an SX-1 to a CD32 enhances the brightness and clarity of the image, even through the S-Video and composite outputs, I would have thought it would degrade it because of more power being sucked out, but such is not the case.

I found this (http://www.ianstedman.co.uk/Amiga/amiga_hacks/Amiga_Power_supplies/amiga_power_supplies.html#Stock_Amiga_Power_Supply_ratings) while I was looking around for info on the A500 PSU. Hope this helps.
Regards
edit: And it may be of use to others, got power consumptions of various setups there as well. To get a power in watts you'll have to use the equation for ave power in an AC circuit, which I'm not going to try and type without maths symbols
:-P

My cd32 power supply will power my CD32, SX-1, 8meg ram, 812meg mini laptop harddrive and an external floppy. However, if I plug headphones in, it doesn't have enough power to boot (it works if I plug them in after the OS has loaded though).

leirbag: i use a fmv card yes but i have a switch for the fastmem and as soon as i use the fmv it disconnect the 8mb jumper and swith to 4mb! , very easy..
and how to install os3.9 , well i advice you to check out the other threads here on amiga.org , but i will tell u here the basics , some versions of the CD (3.9) needs you to install the Recovery disk FIRST and then boot with that! , yeah it sounds insane but thats what i had to do, but then again thats what i always do as thats what the docs say :)
when you do that then the "libs" problems wont appear after install , this is because its locked when in use and the 3.9 installer locks it for some weird reason.
anyway more answers in the os3.9 and exec threads recently discussed here on amiga.org
also, i use SFS and a idefix EIDE99 in my sx-1 ..
cheers

I have OS3.9 on DH0 and OS3.1 on DH1. Both partitions are ticked as bootable in HDToolbox. I just select whichever partition I want to boot from at startup. The reason for having OS3.1 too is because some games (mostly older hard disk installable games) don't like OS3.9.
I plugged my A500 PSU on my A1200 and vice versa, and no problem.
That's right, because they have the same connector. But I changed the connector on my 60W A500 PSU to a CD32 (round not square) power connector.

Get outta here! really? it does this automatically? or do you have to hit a switch? wont this damage one of your boards?
I have software that lets me run Video CD's from workbench and SCALA in full screen from my SX-1, so If i had this little hack of yours,are ou saing that I will have 8megs and then when I tell my software to run a VideoCD that all of the sudden the 8megs switches to 4 megs and then runs the VCD wihout me touching any hardware? and then switches back once the VCD stops playing?
if so.......LET ME HAVE THAT HACK!

@cyberus
Nice link. I was really after more detail, though... ;-)

@Abou27
My stock CD32 was rated at 17 Watts. It would not power my SX32 Pro + HDD + Floppy.
@Leirbag28
Have you had problems with the SX32 shuttle board too?
I have to position mine correctly for the damn thing to work. I soldered wires from the PSU to the CPU to overcome the supply drop problem.

@Stedy
"Have you had problems with the SX32 shuttle board too?"
No I have had no problems with this board,but did with my First SX32pro 50Mhz.............the problem was that the heat the 030 and FPU were generating was causing the SX32 circuit board to become bent out of shape going downwards till it stopped functioning. I still have that board. But the original CD32 power supply, powered it completely fine even when completely loaded and then some. As I said earlier, if your CD32 power cant handle the SX32, its because of the way your particular backplate of your SX32 handles the power, and I dont think there is anything you can do about it but add a bigger power supply. Also I soldered a fan directly to the CD32 power connector rather than take it from the Disk drive port as i usually did......even though my SX32 works fine like that, I wanted to have a floppy always connected.
My hopes one day is to connect the FMV card at the same time with he SX32 both internally.
