Souped up A1200 power requirement advice needed

[-Acid-]

I've got an A1200 here running an Apollo 060 clocked up to 66mhz, it has a Lyra keyboard adapter, Indivision 1, DVD drive, 1 floppy drive and a mechanical 3.5" hard disk. This all runs fine on the PSU I have in it. I recently acquired a Mediator and a Voodoo 3 graphics card for it, I installed these and booted up without the hard drive connected. It booted to the kick start screen and in the early startup menu it sees the Mediator. I decided to plug in a CF adapter instead of the hard drive to check things over before messing with my hard drive's WB install. On the first boot up it found the CF card and started to boot to the point where I think it restarts for load module but when it resets it wouldn't go any further, as if it had stopped seeing the drive just sitting on a black screen. I powered it off and checked connections but now when I boot it doesn't even recognise the drive is there (card and it's contents are fine in WinUAE). Put my real hard drive in and doesn't see that either.

The PSU did not come with the Power Tower as I had to get a stronger one to power the 060. The last time I had a Mediator I could not get it to work and sold it, but at the time I didn't think about the power requirements so i'm hoping this is the problem. Next I disconnected the DVD drive, floppy drive and removed the Voodoo card. Best it can muster now is seeing the partitions if I boot from cold and go straight to the early startup menu and then I can boot with no startup and get to a dos prompt. If I try to boot normally it goes straight to the kickstart screen after a few seconds and then if I soft reset and check in the early startup menu nothing is there hd wise. If I connect the floppy drive it doesn't even see the CF drive attached to it from the first boot.

So now i've only got the main board, mediator, indi, lyra and cf attached and it still is incapable of booting properly. Disconnecting the other bits sort of made some progress so what does anyone think my next move should be? Should I be looking for a more powerful power supply? and if so will either of these fit the bill?

ive got a power tower with sortof similar config,i changed my power supply as the one that was in it failed

it still wouldnt boot,without the apollo?

I didn't try that i'll give it a crack.

Removed Apollo and it still does the same thing. Sees the CF card though, tries ...... okay i'll own up (feel like a right tit now).

I realised it might be a problem with scsi.device... I was loading the A4000 one on the A1200 duh... it's loaded up from the CF card now with the floppy attached, i'll just reattach everything else now and make sure there's no power problems.

youll prolly have to boot it from floppy,just use a workbench disk so the harddrrive spins up but dont boot from harddrive

Right new problem with this system which could be related so i'll continue on this thread.

I've recently added a Mediator to the system with a Voodoo 3 (i've also added a Sound Blaster PCI 128 and a Realtek network card but I had the problem i'm about to describe even when it just had the Voodoo attached to the Mediator).

When Workbench loads up the majority of the time the keyboard will not respond when typing on it or if I open a shell or a text editor a random character is constantly appearing as if they key in question is being held down but no other key will respond. Examples i've seen today are the letter k and the number 4, a couple of times I've loaded Opus 4 and tried to scroll down one of the listings but it kept jumping back to the top of the list when I let go of the slider (sometimes the other way around). Sometimes the caps lock light will come on when pressed and sometimes it won't, control A A works and resets the machine every time no matter what else is going on. If I boot without startup into a dos prompt the keyboard seems to work normally.

I'm using the same PSU as pictured in the first post and the hardware in the system now is the Mediator, Voodoo3, Sound Blaster PCI 128, NIC card, Apollo 060 (overclocked to 66mhz 64mb ram), two hard drives, dvd drive, lyra2, 1 floppy drive and a buffered interface. The PSU sticker says the total output for the +5V linei s 20 amps, is this enough to power all of the hardware in this system? could a lack of power be causing this weird keyboard behavior?

The same thing happens with an A2000 keyboard and two A4000 keyboards, all of these keyboards work perfectly on my A4000.
