I have three power sources feeding my 5-year old BlizzardPPC:
* A 3.5" power connector connected to the A1200 floppy power point. This can get very hot. :-x
* A power connector fitted to the BPPC fan power.
* A power connector fitted to the original A1200 power point. This is fed via a 5.25" power connector. This was my last attempt at fixing my power problems, and it worked - or at least, it solved the crashes.
As you can see, the BPPC is a HUGE power hog, and you'll have problems no matter what the PSU. Before I set things up like this I blew two A1200 power bricks trying to squirt more power into the A1200 motherboard (even though I have a tower with a heavy duty PSU). I don't get crashes any more, but my A1200 still doesn't have enough juice to power my scandoubler. Bye-bye AGA. Pah.
